How to properly delete projects in PlatformIO? - c++

I use PlatformIO with Visual Studio Code on Windows 10.
Now whenever I:
create a Project with a name X
close Visual Studio Code
delete the Project folder X
open Visual Studio Code
create a new Project with the same name X
I get an empty project with a main.cpp file as expected, but the IDE shows an error for the line:
#include <Arduino.h>
The Error says: "Include Error recognised. Update your includePath." (Translated)
However, if I try to build, it compiles just fine. Even uploading and running works.
This include error appears not only with Arduino.h but with all includes, even if the file is in the exact same location. And it appears in other files than just main.cpp as well.
Can you tell me why this happens? How can I reuse the project names of deleted projects? Or If I should not delete projects like this (delete the project folder), how else would I delete a project?
I tried this with multiple project names and different boards, always with the same result.
Things I tried so far:
I found a Folder .cache in the PIO directory. But unfortunately renaming it (after step 3) did not help: after restarting PIO it recreated the folder as expected but the error message is still here.
In the same location there is a file homestate.json that among other things contains the path to recently opened projects. I removed those entries without luck.

I am just starting out with VSCoode and PlatformIO so i can't tell you why all of what you are seeing is happening is happening.
I use VSCode v1.63.0 on Windows 10.
If you want to delete the old project name, reuse it or not, you can bring up the Command Palette under the View menu (Shift-Control-P for me) and search for Workspace: Remove Folder from Workspace...., it will only be listed if you have projects in the workspace. A list of projects will be displayed, selected which one to delete and click on it. There will not be a confirmation prompt.

Cannot compile resource for application manifest in C++ Builder 2006

I am trying to add the application manifest to a program built with C++Builder 2006, by following this article.
(The manifest is to obtain admin rights for my program, which contains "setup" in his name and so it triggers the “This program may not have installed correctly” warning).
I have the MyApp_Setup.exe.manifest in the project folder, along with the MyApp_Setup1.rc file, which is present in the project.
When i try to build, i get:
[RC Fatal Error] MyApp_Setup1.rc(1): File creation failed
What i'm doing wrong, or what should I do?
question edited 'cause i messed up the filenames and the output error didn't matched
Found the problem.
In the project options I always set an "_obj" output folder, but the resource compiler WANTS an existing "debug_build" folder to write the .res file.
It don't create the directory, hence the error in the file creation.
If i remove the "Obj" option, or once you have the "Debug_Build" folder present, everything compiles.

Where should i save codeblocks projects?

so i downloaded codeblocks codeblocks-13.12mingw-setup-TDM-GCC-481.exe
when i try to run main.cpp i get this error message:
Failed to open 'C:\Users\$imba\Documents\Codeblocks projects\test\main.cpp'.
this is a detailed summary of what i did prior to opening main.cpp
i selected the defaults all the way through the end. I created a seperate folder (called Codeblocks projects) in my documents to save the projects in.
now when i went to create a new folder, i selected console application, C++ and then i named my project test. i decided to create the project in the Codeblocks projects folder that i created. the resulting filename comes out to be C:\Users\$imba\Documents\Codeblocks projects\test\test.cbd
i then selected
GNU GCC Compiler,
'Create Debug Configuration: Debug'
output dir: bin\Debug\
object dir.: obj\Debug\
i selected create Release configuration,: 'Release'
output dir.: bin\release\
objects output dir.: obj\ Release
Finish
when i double click on main.cpp is when i get the error message
Failed to open 'C:\Users\$imba\Documents\Codeblocks projects\test\main.cpp'.
please help, i need this program for my course.
Try saving it in a folder in C:\, like C:\Cpp\. Code::Blocks may be having problems with the space or the $ in the file path.
I just created a new folder CB-Project under my D: drive where I have codeblocks installed.
You may want to look in the directory that you have CB installed in first, you may also find this in program file (x86) or the codeblocks sub directory. Look for a file named that may have proj or project in it's name. If you don't find it you can just create a new folder. You will have to put the new folder name in the CB path so it will find it.

New to Xcode can't open files in c++?

I've been using windows in a class I've been taking but I am trying to run a basic code to figure out how to open/close/input/output from files on Xcode and the code I usually use on visual studios isn't working any idea why? thanks!
#include <string>
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream fin;
ofstream fout;
string input;
fin.open("inputFile.txt");
if(fin.fail())
cout << "File failed to open." << endl;
fin >> input;
fout.open("outputFile.txt");
fout << input;
}
Put your .txt files in the same directory where your main.cpp file is (or anywhere you like).
In Xcode go to Product > Scheme > Edit Scheme > Run (on the left) > Options (middle top)
Down under Options for "Working Directory" check “Use custom working directory” and set it to the directory where you .txt files are located.
To work with the files, you will have to specify just file names, e.g. in_file.open("inputFile.txt"); no path is necessary.
Here's a completely different approach: Have Xcode copy the input file for you.
Select your project in Xcode
Select Build Phases
Click the '+' button to create a new Build Phase
Select New Copy Files Build Phase
Select Products Directory
Click the '+' button to add your file
Click Add Other
Select your input file and click Open
Check the Copy items… checkbox and click Finish
Now every time you build your project, the input file will be copied to the same folder as the executable no matter where it is built. Of course, to see the output file, you'll still need to find the executable in Finder.
The answers don't really explain the problem so I thought I'd do that.
When you pass a relative path like "inputFile.txt" to file APIs, it's treated as relative to the working directory when the program is executed. This is the same as the 'working directory' when you use cmd.exe or Terminal.app or command lines in general. The Unix command pwd ("print working directory") displays the current working directory. On Windows running the command cd with no arguments performs the same function. (On Unix running cd with no arguments will change the working directory to the user's home directory.)
When you run a program from the command line, the command line shell sets the program's working directory. When you run a program from within an IDE, the IDE sets the working directory. Since, unlike on a command line, there's no obvious answer for what the IDE should set as the working directory, Visual Studio and Xcode set the working directory to different locations by default: Visual Studio sets the working directory to $(ProjectDir), the directory containing the Visual Studio project file; Xcode sets the working directory to the build products directory, i.e. the location the executable was written to.
Some possible solutions to your problem are:
Do not use a relative path, and therefore don't depend on the working directory. This isn't much help in making the program more portable, because the absolute paths will also differ between platforms, and so you will still have to 'configure' the program for each platform. In fact using an absolute path is worse, because it means your source code must differ, whereas it would be better to keep that difference confined to each platform's build configuration.
Configure the IDE to use your desired working directory. Visual Studio can be configured by right clicking the project, selecting Configuration Properties > Debugging > Working Directory, and setting the working directory to the desired path (potentially using Visual Studio build variables).
nepete's answer describes how to configure the working directly set by Xcode.
Configure the IDE's build process to copy your data files to an appropriate location. In Visual Studio you would do this in a C++ project by configuring the project's Properties > Configuration Properties > Build Events.
SSteve's answer covers how to configure additional build steps in Xcode.
I'm guessing you have inputFile.txt in the folder that contains your source code. That's not going to work. You need to put it in the folder that contains the generated executable. To find that folder, right-click on your app under Products and select Show In Finder.
This image shows what it looks like for a command line program. It also shows the Finder window that was opened. As you can see, it is a different folder than the one containing the source code.
As suggested by nepete, edit the scheme, but use $PROJECT_DIR as the custom working directory. Helps with moving the project around, or working in two different environments (e.g., home and office).
BTW. $PROJECT_DIR is one of the Xcode Environment Variables, and also helps with passing file names as command line arguments to programs (settable under "Arguments" in the scheme).
I've struggled with the same problem today. I wanted to add C code to my Swift project and my file pointer was always NULL.
Unfortunately, in XCode 9 for iOS app, I couldn't change the working directory. Changing Build phases didn't help me either. After 4+ hours of trial and error, that's what I've come up with finally and it works:
when copying files to XCode, I've chosen "Create groups", but I needed to choose "Create folder references":
I created a new objective-c file (.m) and copied all my C code there.
I left untouched .h files (XCode generated bridging header and my own .h file with public functions declaration). Now my project structure looked like this:
In my dict.m file in place of previous plain c fopen part:
FILE *dic = fopen("dictionary.txt", "r");
I added obj-C code:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"dictionary" ofType:#"txt"];
FILE *dic = fopen([filePath cStringUsingEncoding: NSUTF8StringEncoding], "r");
And it works now without any problem! It's just amazing!
ps I decided to write this answer in case it will help someone like me and will save them some time. If you know how to change working directory in XCode 9 for iOS, please, leave me a comment - now I am really curious why I can't find it.

"Error C1083: Cannot open source file" Shouldn't Be Looking For The File At All

I was trying to #include a cpp file with some functions so I can use that cpp file later with other projects. It gave me an 'already defined in .obj' error and since then that .cpp file was like binded with my project. (I understood that's not the way, the answer here helped me with the already defined)
If I exclude the .cpp file from the project, remove it from the directory and remove the #include line it still looks for it:
c1xx : fatal error C1083: Cannot open source file: 'std.cpp': No such file or directory
Diagnostic:
Outputs for D:\MY DOCUMENTS\C#\PROJECT\D3DTESTC++\COWS AND BULLS\CBMAIN.CPP|D:\MY DOCUMENTS\C#\PROJECT\D3DTESTC++\COWS AND BULLS\STD.CPP: (TaskId:15)
It shouldn't be looking for the std.cpp at all, I removed it! So is there a way I can reset the project and recompile so that the program doesn't look for it? I already tried Rebuild and Clear -> Build Project
When I ran across a similar problem with VS Express, I wound up having to open up the the .vcxproj file (which is just XML), and remove the offending
< ClInclude Include="FILEPATHANDNAME" > tags.
Many of the solutions here will not work
Fullproof method:
Open the vxproj file that is giving you trouble in a text editor.
remove all references to the file it cannot find.
OK, I have no idea how I did it but I'm still going to try to write what I did.
Save all and Close solution
Open the .vcxproj file (not .sln)
Build -> Clean [Project Name]
Save all and Close
Open the .sln file again.
Build -> Project Only -> Clean Only [Project Name]
Build -> Project Only -> Build Only [Project Name]
That's exactly what I did and worked for me. I think the main thing to do is clean, save, close, open, build, but I'm not sure.
In Solution Explorer you can select/deselect option "Show All Files".
Try both options and make sure excluded file is not included in project for both of them.
That's what I had:
I used "Show All Files" option (so you can see all the files in project directories). I excluded one of my .cpp files from project. However, it behaved as this file is in project.
That's how I managed to fix it:
I switched "Show All Files" off and saw this file still belongs to project! So I excluded this file once again.
As I see, that's a known issue.
This worked for me, hope it will be useful for someone else.
Try to verbose builder output to see exact steps of what's going on. I suppose, you use Visual Studio, right?
Go to menu "Tools -> Options"
In options dialog, select "Projects and Solutions -> Build and Run"
Change current mode of "MSBuild project build output verbosity" from "Minimal" to something like "Diagnostics" or "Detailed".
Rebuild your project and investigate Output windows
Builder dump should shed more light on your current settings (I suspect you have more references to that file than you expect)
This happened to me because I renamed folder from inside the IDE. None of the above solutions worked. The only way to fix this is by opening vcproj in notepad and you should see the offending files in the <ItemGroup>. Just delete those lines.
Or sometimes, like in my case, the issue is simply in the naming of the folders in the location. I had a very long path with folders that I like to name with special characters so they show up at the top and it's easy to access them.
As soon as I put my solution in a folder just in D: drive, the issue was gone.
When I renamed a file, I found I had to go to SolutionExplorer, Source File, select the file, first exclude from Project, then re-add it to project, and rebuild the solution it lives in. It was still showing up as the old file name under Source Files for me.
I had the same problem, but I had another .sln worked fine. After tooling around with the Project->Properties-> to make them look identical, nothing worked. I opened both .vcxproj files and copied the contents of the working version into my non-working version. (I noticed that the two files had different lengths. The non-working version was longer by about 20 lines.) I just changed the RootNameSpace to the non-working version's name. I saved the non-working file and presto! It worked.
I removed those sources from Project and re-added them. Somehow, references were messed up after a hurry project refactoring.
For people having problem related to "error C1083: Cannot open source file":
Error is caused by settings in *.vcxproj file. Probably you deleted/moved source file by file explorer, not by Visual Studio's "Solution Explorer". Thus, your *.vcxproj file is corrupted. Fix is to manually correct settings in *.vcxproj file.
How Visual Studio settings files work
Visual Studio saves solution's info into file. This file is usually in project's solution directory, has extension .sln and base name is same as name of solution, f.ex.:
NameOfSolution.sln
Similarly, project's info is saved into one file (each project has its own file). Base name of this file is name of project, extension is .vcxproj, and usually is located in subdirectory named as your project, f.ex.:
NameOf1stProject/NameOf1stProject.vcxproj
NameOf2ndProject/NameOf2ndProject.vcxproj
Both *.sln and *.vcxproj files are textual files. You can open them by using Notepad.
How to fix problem
Find *.vcxproj file responsible for your project.
If you don't know where it is, open in Notepad the *.sln file of your solution. Search for name of your solution. You will find line like:
Project("{9AA9CEB8-8B4A-11D0-8D22-00B0C01AA943}") = "NameOf1stProject", "NameOf1stProject\NameOf1stProject.vcxproj", "{A8735D0A-25ED-4285-AB8F-AF578D8DB960}"
Value under "NameOf1stProject\NameOf1stProject.vcxproj" is location of *.vcxproj file of your project.
Open found *.vcxproj file by text editor (f.ex. Notepad).
Search for line on which is filename you are struggling with.
Example: if you are looking for "RemovedFile.cpp", then you should find line:
<ClCompile Include="RemovedFile.cpp" />
Delete that line.
If you have opened Visual Studio, it asks you if it should refresh solution - select yes. If it is not opened - just start using it.
In case of any problems, try to rebuild solution (top banner -> Build -> Rebuild Solution)
In my cases, it worked. 30 mins of trying to fix, <1 minute of fixing.
This helped in my case. To sum it up, my path to the project was too long, so I moved my project to something shorter i.e. D:\my_project and everything worked in a blink of an eye.
I had this same problem, but for me the issues was that I was using Bash on Windows (WSL) to clone the repository and then using VS to compile.
Once I deleted my clone and used Windows command line (cmd.exe) to clone the repo then the error 1083 went away.
This is caused by not removing/deleting the file properly. Go to Solution Explorer, select your solution, at the left corner, activate the icon: show all files.
(if you already removed the problem file, restore it from recycle bin)
Select the problem file, do remove and delete from within Solution Explorer and you should not have this problem. And remember to do it the proper way from now on.
This is on MS 2010
If you have that file in your project directory but you still got the error, on your IDE go to Solution explorer--> Remove that file-->then open the project directory on your file explorer-->Select that file and drop it on a specific location in IDE solution explorer. I fixed it this way. I use the Windows platform.
I got this error when I got a code from my peer and I tried directly running it on my system. Ideally to avoid such errors, I should have just copied the source and header files and should have created the VS solution of my own.
To resolve the errors I removed the files from the Solution Explorer and added them again. Following image shows the Solution Explorer window.
The remove option comes after right clicking on the file names.

What are C2471,C1083 errors related to a VC2008 project and how to correct them

I had a VC2008 project very complicated.Inorder to understand it's inner workings I tried to simplify it and now I am getting 289 errors of the following type for most of the files:
Error 5 error C2471: cannot update program database 'c:\users\ryan\documents\visual studio 2008\projects\vc\myinfo\cli\debug\vc90.pdb' c:\users\ryan\documents\visual studio 2008\projects\vc\myinfo\cli\mediainfo\file__analyze_buffer_minimizesize.cpp 1 CLI
Error 6 fatal error C1083: Cannot open program database file: 'c:\users\ryan\documents\visual studio 2008\projects\vc\myinfo\cli\debug\vc90.pdb': No such file or directory c:\users\ryan\documents\visual studio 2008\projects\vc\myinfo\cli\mediainfo\file__analyze_buffer_minimizesize.cpp 1 CLI
My system : win7/VS2008
Solution 1: Locate *.vcxproj file in your solution, open in a text editor and search for 'DebugInformationFormat' and set it to 'OldStyle'.  Reload your project and build. If you have multiple projects in your solution, this change needed for all the *.vcxproj files.
< DebugInformationFormat>OldStyle< /DebugInformationFormat>
Solution 2: From Visual Studio, on every project in your solution right click and open Properties. Expand 'Configuration Properties' > 'C/C++' > 'General'. Change the 'Debug Information Format' to 'C7 compatible (/Z7)'. Then build your solution.
This worked for me. (YMMV = Your mileage may vary:)
I've seen the same behaviour when converting a VS2003.Net solution to run on later IDEs. My guess is that your solution contains multiple projects which point to the same intermediate directory. In VS2005 and later, projects that don't depend on each other can be built in parallel so that if the same working dir is used, you can get file conflicts like this.
Check this as follows. In Solution Explorer, right click on one of the failing projects and select Properties. In Configuration Properties -> General section, make sure that every project has a different 'Intermediate Directory'. Try your build again using 'Rebuild Solution' to clean everything out.
Most of the times when I get "C2471: cannot update program database" it's because the PDB file is locked for some reason. Usually in my case that turns out to be because I have the program running in some other window, which loads the PDB file in to memory.
When that's not the reason, I find doing a rebuild-all magically fixes the problem.
I've encountered the same type of error myself with no end of frustration.
I finally fixed it by applying the Microsoft hot fix found in this knowledge base article: http://archive.msdn.microsoft.com/KB946040
This worked for me.
Kill mspdbsrv.exe and reload Visual C++

You can delete the *.obj file and rebuild the solution again, This problem might solve. Below link might be helpful for you-
