I installed Eclipse with CDT plugin. I created a simple TCP client software that runs on Windows. I can open the project on Ubuntu also. I'd like to change build configuration in order to create Linux executable. Is it possible to create executable for the operating system that the project is compiled. I mean if I compile the project on Ubuntu, there should be Linux executable and if I compile the project on Windows, there should be Windows executable. Is it possible?
It is possible. When you are creating a Project in Eclipse, you are provided with two build options. One debug and one release. The release build will create the executable for the OS in which it is run.
Good Luck!

I am using Neon.3 Release (4.6.3) Eclipse IDE for C/C++ Developers under Ubuntu 15.5. When I build an run my C-program the program
the program executes without any errors/warnings
delivers the expected output in the eclipse-console
and generates an .exe file in the the debug folder
For me it is very much surprising that an .exe file is generated using an Linux OS (I thought these files can only be created under Windows?). How can I configure Eclipse to generate a typical Linux-executable instead?
Many thanks!
Extensions don't matter much in Linux. You can name an executable something.exe and it won't change how it runs...
Please note: Although I'm specifically talking about the Eclipse CDT plugin, I'm almost 100% confident that any Windows/C/MinGW programmer can answer this question.
I'm on Windows 7 and am trying to write and compile a simple "Hello, C!" C application using Eclipse's CDT plugin. I'm reading their docs which state that having GCC installed is a prerequisite.
I just installed MinGW, making sure to include the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Back in the CDT docs (under the section titled Windows configuration), it states that I need to add g++, make and GDB to my PATH.
I'm wondering where MinGW installs these utilities, so that I can add them to my system PATH, and make the Eclipse CDT recognize their location at startup.
When using the Eclipse CDT plugin, you need GCC and its 3 specific utilities installed locally. These three utilities are: g++, make and gdb.
On Windows you can choose to install these utilities via Cygwin or MinGW. For a MinGW-based solution, go to their site and download the MinGW Package Manager. Then open the manager and install the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Then go to File >> Apply Updates and apply them. This will install the 3 utilities to the following directories on your machine:
C:\MinGW\bin\g++
C:\MinGW\bin\gdb
C:\MinGW\msys\1.0\make
Add these 3 binaries to your system PATH, restart Eclipse and you are all set.
I start to learn c and c++ programming and I write it in Linux.
Can I make binary file with g++ and run it as exe in window 7? or i need to compile the code in windows again?
You can use a mingw cross compiler to build windows binaries in linux. In Ubuntu (and I guess other Debian variants as well) the package is called mingw32. You then have a cross compiler under the name i586-mingw32msvc-g++ (or similar). For building simple command line programs without library dependencies this is an OK solution.
If you need more then this I'd recommend you use MXE (M cross environment). MXE installs its own cross compiler and can build many libraries for you so you don't need to care about how to build the library dependencies.
For example the OpenSCAD project (a 3D CAD program that is using Qt for its GUI) is using MXE for building the Windows releases. See this page on the OpenSCAD wiki for a description of the build process.
How can I cross compile my GTK+ app (written in C) from Linux to Windows? Could I just replace the "gcc" command with "mingw32"?
Fedora has a great mingw32 cross-compiler toolchain which comes with lots of precompiled libraries, including GTK+ and gtkmm. For most applications you just need to install the cross-compiler and the cross-compiled GTK+ libraries:
yum install mingw32-gcc mingw32-gtk2
Once everything needed is installed, compiling your application is just the matter of running "mingw32-configure" followed with "make".
More information at the project page https://fedoraproject.org/wiki/MinGW
You can use mingw-cross-env - all you have to do then is to change your CC/CXX environment path to use the i686-mingw32- prefix and export the mingw-cross-env bin dirs (both) to your PATH variable (or if you are using autotool it's even easier) - see the documentation on the homepage.
There is actually a project called MXE that does exactly this.
Pre-build package
You can download my pre-build binaries if you want.
Build from source
You can also build the code from scratch ideally also applying this PR to update to the latest GTK 3.24 version.
MXE has a easy wrapper (x86_64-w64-mingw32.static-cmake) to cross-build your project towards Windows, while using Linux. Allowing to evenly statically build your project into a single .exe file! Of course shared builds (x86_64-w64-mingw32.shared-cmake) are also supported. The example wrapper scripts are meant for CMake based projects.
Before you can build your project with MXE, you need to build the GTK3 from source-code. (There are some Linux packages available, but mostly out-dated). If you are using C++, you can also build gtkmm3. Since you are in place C, you only need to build gtk3.
git clone https://github.com/mxe/mxe.git
Become root user: su
mv mxe /opt/mxe
cd /opt/mxe
Build the MXE project yourself:
For static builds under Windows 64-bit for GTK3 & Gtkmm3:
sudo make gtk3 gtkmm3 -j 16 MXE_TARGETS='x86_64-w64-mingw32.static' MXE_PLUGIN_DIRS='plugins/gcc12'
For shared build to Windows 64-bit (again GTK3 + Gtkmm3):
sudo make gtk3 gtkmm3 -j 16 MXE_TARGETS='x86_64-w64-mingw32.shared' MXE_PLUGIN_DIRS='plugins/gcc12'
More info see the tutorial steps on MXE.cc.
Once you done the cross-compile environment / MXE build. Now you can use the CMake wrapper scripts I mentioned earlier. Those scripts are located in the /opt/mxe/usr/bin/ directory.
The scripts (like x86_64-w64-mingw32.static-cmake) can now be used to compile your project towards Windows, while using the Linux operating system. The build result would be an Windows .exe.
Disclaimer: I personally created this PR for MXE to update GTK to the latest 3.24.x release.
I've made a small application in C with Netbeans.
I've ran the application in Netbeans and it created an exe.
I used that exe and it worked fine on my comp but when I move it to other comp it says:
"This application failed to start because cygwin1.dll was not found. Re-installing the application may fix this problem."
How can i create the exe so that it runs anywhere?
The problem is you're using Cygwin GCC to compile your code. Cygwin provides a unix-like environment
if you're not doing anything Unix-y you can recomplie -mno-cygwin - see Can you statically compile a cygwin application?
if you are using Unix calls you'll need to distribute cygwin1.dll along with your app
or you can recompile with a different compiler, e.g. a GCC that targets mingw32 not cygwin, or one of the free (as-in-beer) Microsoft compilers from the platform SDK or Visual Studio Express downloads.
