I followed these steps to build chromium source code on linux.
I build only chrome. Finally i have finished it successfully.
For output i opened out/Debug directory, i found some files but, i don't know which file is executable or anything extra i have to do to create executable. I didn't get any information from above link also after building source code.
Please help me regarding this. Thanks.
Just Run the shell script file chrome-wrapper in out/Debug directory, it launches Chrome Browser automatically.
After building chrome (via make chrome, or the like), you'll have an executable binary at out/Debug/chrome. Other packages (notably the unittests) generate similar binaries: out/Debug/unit_tests or out/Debug/browser_tests for example.

Intro
I have a CMake-based C++ project. Until now I build and ran the project via CLion. Everything worked fine until I tried to run the .exe-file directly (not via CLion).
Problem
When I navigate to the cmake build directory in order to start my program via the executable file, it fails with the following message in the popup: Cannot continue the code execution because libgcc_s so-1.dll was not found. Reinstalling the program may resolve the issue.
I have the following questions
If I interpret the error message correctly, then this dll is missing on my computer. So I ask myself, why does my program still work when I start it via the development environment (CLion), although the error message expressly states that the source code requires this dll?
Is it the fault of my application/source code that the error appears or rather the current state of my computer? If the former, how can I prevent this error from appearing for other users?
What is the best way to fix this error? It's obvious that I need to download this dll, but where is the best place to put it (which directory and environment variable to use on Window)?
Which source is trustworthy to download this dll? I don't want to download any malware under this dll-name.
Optional: What kind of library is that? What functionalities does it offer?
Additional information
I use CMake as my build tool, CLion as the IDE and MinGW as the compiler.
What I have did so far?
I made sure it still works through the IDE.
I found this dll does not exist in the MinGW installation folder.
I searched the web for more information. Unfortunately, there are only pages unknown to me that only offer the download of this dll. That doesn't satisfy me.
I found the cause of my problem: I had two MingGW installations on my machine. Once the installation that comes with CLion and a separate one. The latter did not have the required dll. However, CLion used its own installation, which in turn owns the DLL. So the solution was to remove the separate installation and include the path to the CLion installation's bin/ directory in the PATH environment variable.
This file is part of MinGW-w64 when using SEH as exception model (as opposed to Dwarf or SJLJ). You need to distribute the .dll files your .exe file(s) depend on in the same folder as the .exe file(s).
If you don't have that file, then you probably have been using libraries compiled with different versions of GCC/MinGW(-w64). I recommend building everything with the same compiler to ensure stable binaries.
Tools like Dependency Walker can help you figure out which .dll files your .exe file depends on.
Or use the command line tool copypedeps -r from https://github.com/brechtsanders/pedeps to copy the .exe files along with it's dependencies.
I'm using Ubuntu and I have written my c++ code in Eclipse Neon.
My workspace contain 4 projects. The main project is called BaseCppProjectRun (it contains main.cpp file) and I have other projects with these names: Encoders, frmwrk, NetworkLayer - the BaseCppProjectRun using each one of them.
If I running my program directly from eclipse everything works.
But I want to running my program from terminal - and I can't.
Because When I'm trying to run my progrm like this:
root#ubuntu:/builds/BaseCppProject/BaseCppProjectRun# ./Debug/BaseCppProjectRun
I'm getting this error:
./Debug/BaseCppProjectRun: error while loading shared libraries: libfrmwrk.so: cannot open shared object file: No such file or directory
As I said before, if I'm running it directly from eclipse everything works.
How can I run my program from terminal?
How is Linux supposed to know where to find libfrmwrk.so, if you don't put that either where it normally looks nor tell it where it can be found.
Eclipse seems to set up the paths the runtime linker looks into so, that when your program is loaded, the runtime linker knows where to find your libfrmwrk.so and so on.
You'll either have to
install these libraries (.so's) so that they are found in default locations, or
set LD_LIBRARY_PATH to contain all the folders to look into.
I haven't worked with Eclipse CDT in ages, but you can by now probably export some project formats that allow you to easily install things.
Another thing: It seems you're running software you're still debugging as root: That is a terrible idea, and if it can be avoided, avoid it.
I finally figure it out!
Refere to Marcus Muller's answer + my steps this is how I have fixed it ( all steps via terminal):
Create new directory in my workspace directory and called it libs.
In each one of your projects do: right click > c/C++ Build > Build Steps (tab) and in Post-build steps paste this:
cp ${BuildArtifactFilePrefix}${BuildArtifactFileName} "${WorkspaceDirPath}/libs/"
This code copy the so files directly into your libs directory when you compile your program.
And finally, in your terminal execute this:
export LD_LIBRARY_PATH=/builds/BaseCppProject/libs/
Now you can run your program via terminal.
I wrote a program in C/C++ and compiled it using Cygwin. When I ran the compiled file, I receive an error about a missing library.
Cygwin is like a simple framework: With every program you build you have to include the library cygwin1.dll.
Important note: Downloading the library online might be risky as it can be a virus.
To fix the issue:
1. Go to your cygwin directory. Usually that is C:\cygwin or C:\cygwin64.
If you don't know where cygwin is, download the setup file and run it. The installation path the installer suggests is the Cygwin installation location.
Tip: Don't use a directory to put cygwin in that includes spaces (" ") as it will be easier to run programs with command-line parameters.
2. Copy the file. It should be in <Drive>:\cygwin\bin\cygwin1.dll.
3. Copy the file to your program folder, the same directory as your exe file.
Your program should run without throwing an exception.
I am trying to build and run Google Test but encountered some issues.
Any help greatly appreciated.
I used CMake 2.8 (with UI) to create .sln and .vcproj files in the D:/MyBuild
directory (as mentioned in the README file of google test).
However, when I try to run the .sln file in the MyBuild directory,
here is what I get (image):
Also, here is a screenshot of the CMake which I used to
create .sln files and .vcproj files in the D:/MyBuild directory.
ps. One thing I noticed is that README was giving instructions how
to use non graphical version of CMake (e.g., 2.6) to install
google test, however I used one with user interface - maybe
I did something wrong there?
You appear to have successfully built gtest's libs in Debug mode. However, by default the .sln doesn't contain any executables, so you can't actually run anything.
If you select the checkboxes in the CMake GUI for gtest_build_samples and/or gtest_build_tests and hit "Generate", then the Visual Studio solution should contain some executables.
From memory, these don't build cleanly, but I don't have MSVC 2010 to hand, so I can't be sure.
I've searched this for a while and haven't found anything answered anywhere:
I have a project in QtCreator that has no compilation errors, and runs fine as a normal C++ project in Eclipse.
However, when I try to run it as a Qt app, it says it could not find an executable and I need to specify one.
As many other sites have suggested, I have searched the directories for the .exe that QtCreator was supposed to make (according to the other sites), but I am yet to find anything.
I'm in no rush, but have spent a long time on this and would like to move on to actually writing the Qt part.
Thanks in advance.
Are you still struggling with the solution ? The most easy solution is, restore default setting by deleting file QtCreator.ini. After that configure project once again by giving build directory path. If you are working on Linux system, run following command to find QtCreator.ini file.
$ locate QtCreator.ini
It will give ouput like this
/home/tan/.config/QtProject/QtCreator.ini
Then delete the file on obtained path using following command
$ sudo rm -f /home/tan/.config/QtProject/QtCreator.ini
Now open project once again and configure with your desired build and run settings.
Upvote if above solution helps you. Btw if I've made any grammatical mistakes, I am sorry for my english. :)
Best luck !!
I'm not sure I understand what you mean by having a QtCreator project and running it in Eclipse or running it as a Qt App but if you are looking for an exe file, QtCreator is probably configured to do shadow builds for your project. This means that build output is sent to a directory outside of your project source directory. If your project is in a directory called MyApp, then look for a directory beside it called MyApp-build-desktop. You should find your executable in there.
