Environment: windows 10, VS2013.
I have a C++ app, using Poco framework (Poco 1.7.6) and I need to launch some batch files. It works without problem, but for a particular script, and I can't figure out the reason.
This particular script is as follows (let's call it buildMySolution.bat):
set BUILD_DIR=%~dp0
call "C:\Program Files(x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat"
msbuild /p:Platform=%~1 /p:Configuration=%~2 %BUILD_DIR%\Mysolution.sln
As you can see the batch file simply compiles a VS2013 solution. Needless to say that this simple batch works perfectly well if launched from command line.
The problem is that this batch is in drive D: (in D:\DevRoot\build\MySolution) and when launched from my app (in D:\ drive as well), I get a "cannot find the path" on the second line.
I tried several modifications in the batch: like forcing C: or cd /D C: ... it can go to C: but not further, it refuses to cd to the directory containing vcvarsall.bat (again, I know the path is correct as the very same script executes fine from command line). It has however no problem coming back to initial directory through a cd /D %BUILD_DIR%.
To launch the script from my C++ app, I use this:
Poco::ProcessHandle handleBuild = Poco::Process::launch(path_to_script, argsBuild);
handleBuild.wait();
The Poco launch is just a thin wrapper around CreateProcessA(), I don't see anything special in their code (Poco Process.cpp).
I tried as well to specify the working directory to be the directory containing vcvarsall.bat, but then CreateProcess fails.
I just found a solution: I changed the line (in the batch buildMySolution.bat):
call "C:\Program Files(x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat"
to:
call C:\PROGRA~2\micros~1.0\vc\vcvarsall.bat
Believe it or not: using DOS names and removing quotes makes it work!!!
Bug or feature, I'm not sure...

Sorry, I'm new to Xcode and not very familiar with it, I use Xcode (command line tool project with external build system) to compile cpp files and automatically execute cpp unix executable files. After the program is compiled (command+R), I set the settings as shown in the screenshot below to automatically execute. Is there any way for me to execute also add additional commands?
Such as iconv.
The following line is what I ultimately want to execute.
./myFile argument1 | iconv -f big5
But my Xcode looks like it's executing only
./myFile argument1
really thanks
On the same place where you setup the build scheme, you can also add a post-build script.
Go to the left of the panel, and expand Build
Select Post-actions
Near the bottom center, click on + -> New Run Script Action
Add script like you would run them in terminal
Note the current directory will not be where the project is built
You can use ${TARGET_BUILD_DIR} macro for the build directory
Note, you want to make sure to select your current project at the Provide build settings from so it can import the correct path macros like TARGET_BUILD_DIR
A screenshot of adding a post-build script:
*Older versions of Xcode might have different GUI, but the idea should be about the same.
Sidenote, ⌘R is really for running the program within Xcode, consider using ⌘B.

I have downloaded the ninja-win.zip folder and extracted it. When I open it, there is a single .exe file in the entire folder. When I double click it a cmd window flashes for a split second. I have also tried running it as administrator, but the same thing happens. What I don't understand is, what am I expected to do with this .exe file?
You must open a terminal (cmd.exe on Windows) and type something like ninja -f /path/to/buld/file. You may also wish to modify the PATH environment variable so that Windows knows where to find the Ninja executable, depending on your setup.
You can simple download ninja.exe file from this Link
https://github.com/ninja-build/ninja/releases
After that you just have to add the path to your ninja.exe file to your windows environment variables and then you can use ninja commands from anywhere in windows.
1. Open cmd in your Project Directory
2. There are guides on the internet on where to save the Ninja.exe so that it'll be callable in Cmd without specifying directory. Either follow them or:
i, Specify Directory when Calling Ninja. Putting "ninja" in Cmd actually calls Ninja.exe and is the same as something like "C:\users\user1\downloads\Ninja". or:
ii, Save Ninja.exe in the same directory as Project.
3. proceed with rest of the command.
Therefore the Final Command would be:
"C:\users\user\downloads\Ninja.exe" -f "D:\Projects\Project1"
i have a problem with VS2008 Pre build command.
I need to compile a lot of XSLT style sheets and generate a common assembly, i use xsltc.exe but the command string is too long for command prompt.
I tried to use also a .bat file, i use the xsltc.exe command in the best way for save some character, like using "\c" instead of "\class", but the problem still remains.
Do you have any suggestion to solve this problem? please note that i can't install on my machine additional tools.
Thank You All!
Can you post the full command you're trying to run?
If you are trying to feed the compiler with whole path names to the stylesheets, would it perhaps help to, in the batch file, cd to the directory containing your stylesheets and then run the following command?
c:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\xsltc /out:MyAssembly stylesheet1.xsl stylesheet2.xsl stylesheet3.xsl [...]
i.e. for example:
cd c:\My\Stylesheets
c:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\xsltc /out:MyAssembly stylesheet1.xsl stylesheet2.xsl stylesheet3.xsl ...
instead of:
xsltc /out:c:\My\Stylesheets\MyAssembly c:\My\Stylesheets\stylesheet1.xsl c:\My\Stylesheets\stylesheet2.xsl c:\My\Stylesheets\stylesheet3.xsl [...]
I have not worked with xsltc (and you haven't provided enough information) so please excuse any formal flaws.
I have a project that I converted from a makefile that has a source file that expects the command line options from the compiler. For example for when the project was built with gcc if you did program --help it would spit out the gcc command line used to compile the program.
How can I do the same thing in Visual Studio, so that it spits out the cl command line used to compile the program? Basically I want to hit F7 (to build solution) and have the whole thing automated. I can't find a macro for it. Thanks
edit; I mean programatically, so for example I want when I run the program for its output to contain the cl.exe command string that is used. You can see the command line at Configuration Properties > C/C++ > Command Line > All Options but I can't find a macro for it or some way to encapsulate it in a file.
Since VS switched the underlying build system to MsBuild the command line as shown in that dialog is created programatically within VS only. It might not even be the exact command line passed to cl: MsBuild itself invokes CL via a task and as such there is no direct link with what is shown in VS nor is there a way to get the command line out of it.
Anyway, there is no such thing as the command line since each source file might have different options. Furthermore I doubt you want the full commandline including the absolute include paths etc. Nobody is interested in that. Now if you make clever use of the macros from http://msdn.microsoft.com/en-us/library/b0084kay.aspx you can sort of recreate the command line yourself since most options are there:
std::string CompilerCommandLineOptions()
{
std::string cmd;
#ifdef _CHAR_UNSIGNED
cmd += " /J";
#endif
#ifdef __cplusplus_cli
cmd += " /clr";
#endif
#ifdef _CPPRTTI
cmd += " /GR"
#endif
//etc
return cmd;
}
Note: are you sure it's worth the hassle? Is there really somebody interested in the command line? It's not even sufficient to build the project. Why not the linker options as well then?
A .vcxproj is a Visual Studio project in the MSBuild project format. You can build it by running msbuild.exe, devenv.exe, devenv.com, using the Visual Studio GUI or the MSBuild API.
Visual Studio GUI uses the MSBuild API. In doing so, it limits the MSBuild output.
If you want more details, change your user settings in Visual Studio:
Tools > Options > Project and Solutions > Build and Run > two verbosity settings
Detailed will show the cl.exe command lines.
The closest thing which I came across cl command line which msuild executes is "hacking" the rsp file used while calling cl.exe.
Using Override compiler solution, I changed ClCompile ToolExe to custom mycl.bat script and this script received an argument which was #tmp-1234xxx.rsp file. This rsp file contained whole command line except cl.exe path, something like -
rsp file
/P /DDEBUG Source.cpp
Then after making desired changes in the rsp file by calling a separate bash script which were very minor for me, I called cl.exe with contents of my rsp file. So, whenever user hits the build button, this script executes.
mycl.bat script
#echo off
SET PATH=%PATH%;/usr/bin //to call cygwin bash
set parameter=%1
set parameter=%parameter:~1% //to remove # in the beginning
c:/cygwin/bin/bash process.sh %parameter%
process.sh
iconv -f UCS-2 -t UTF-8 <$1 >$1.conv //file converted to UTF-8, else bash wasn't handling it well
contents=`cat $1.conv`
#Processing on file contents here
path/to/cl.exe $(contents)
Very nasty solution, but it worked for my use case. I wanted to change the names of the file on the go based on some logic.
The problem I faced is Visual Studio uses tlogs written by CL Task to check while file needs to to be rebuilt on incremental build and my target's tlogs files were not enough. There were tlogs of every command in batch and bash scripts but not for whole target. So, it was building whole thing on incremental builds also.
I was wondering how to open a file other than notepad... Our prof gave us an example:
s = "notepad.exe test.txt";
system(s.c_str());
That will open a file type of "notepad.exe" and the file name of "test.txt"
Main Question:
Now, I was wondering if there was a way to open other type of files, such as Microsoft Excel, Microsoft Word, Visual Studio, or 7zip.
My attempt opened something in a new cmd.exe (because of the START keyword):
fileNeededtoBeOpened = "START \"New Microsoft Office Excel Worksheet.xlsx\"";
system(fileNeededtoBeOpened.c_str());
(This code is slightly different from my original, where I'm trying to open a file from a vector...) but all I really need to know is instead of "notepad.exe" or "START" is there a different command to open different file types that aren't .txt
Also, a side note, I was reading on the internet that it wasn't safe to use system() to open files, is this correct?
I found the answer by myself... for those who are curious, here an the answers:
To open a text file: system(notepad)
To open an excel file: system(start excel)
To open a word doc file: system(start winword)
To open a 7z file: system(start 7zFM)
To open a visual studio file: system(start devenv)
I think you're confused.
System executes a command as you would on the command line (type cmd into the run prompt under start menu to get that).
So, when you type notepad.exe test.txt it's saying:
Open the program notepad.exe which is on the system path (so the
command line can find it to execute that program), and pass the
parameter test.txt to it.
Notepad itself decides what to do with test.txt, in this case it opens it.
So, you can tell it to run any command (program/executable) and pass any parameters to it in reality. If excel's on your system path, you can probably just type excel.exe to open it from your system command. Otherwise, find the location excel is installed in, and refer to it with the whole path to excel.exe and it will work fine.
For example, on my computer, executing "C:\Program Files\Microsoft Office\Office12\EXCEL.EXE" would open excel from the command line. I can pass further parameters to it by having more information (like filenames) after the Excel.exe" portion, just as you did in your notepad example. Using your system command should have equivilent behavior when that line is executed.
If you are only targeting Windows systems you can use the ShellExecuteEx function (part of the Win32 API). You can just pass a filename to it and it will launch what ever program is registered to handle that file type (just as if you opened the file from windows explorer). Documentation is available on MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/bb762154(v=vs.85).aspx
There is some examples on Launching Applications (ShellExecute, ShellExecuteEx, SHELLEXECUTEINFO) MSDN article and lots more elsewhere around the internet.
AS the other guys mentioned , the System function only executes a cmd command, .. notepad.exe is in the system's path by default so it works directly
but for example for me if I want to open a zip file on my desktop , I'd type something like
"C:\Program Files\7-Zip\7zFM.exe" Desktop\zipfile.zip
that's when I'm currently at the my user's directory [by default] , or
"C:\Program Files\7-Zip\7zFM.exe" C:\Users\JiMMaR\Desktop\zipfile.zip
[where JiMMaR is my user name on windows 7]
note that this certain command works only on windows , if you are using another OS this won't work as it is
try doing a
fileNeededtoBeOpened = "\"C:\Program Files\7-Zip\7zFM.exe\" C:\Users\YOUR_USER_NAME\Desktop\zipfile.zip";
and see if that executes or not
edit:
if you cannot escape the space , then try this one
fileNeededtoBeOpened = "C:\Program~1\7-Zip\7zFM.exe C:\Users\YOUR_USER_NAME\Desktop\zipfile.zip";
Ok, firstly - system - is a function that starts a separate process to your program. Much the same as in a command window when you type the command. The command lines you provide will be dependent on the applications you want to launch.
Now, I was wondering if there was a way to open other type of files,
such as Microsoft Excel, Microsoft Word, Visual Studio, or 7zip.
Yes I would be pretty shocked if there wasn't a command line parameter you could specify to load a document in these apps at start up. (Ok not shocked, but it is pretty standard)
Does this have anything to do with c++ - not really - you need to look at references for the applications you mention and see what the command lines parameters are for them. Then craft a string and system(...) to your hearts content.
