I am using a 64bit Intel based machine and want to compile and run 32bit C code in my command prompt. I have bash installed via (Windows Subsystems for Linux) and am using gcc and have the gcc-multilib installed so I can compile using the -m32 tag. The program compiles fine but comes up with this error when I try to run:
bash: ./32test: cannot execute binary file: Exec format error
WSL only supports 64-bit ELF binaries.

You can try to build with a native Windows compiler or in Cygwin instead.

Hey I'm trying to compile a program that requires GCC and g++ 11. I've tried msys2 but it only goes up to GCC 10.04
And some of my libraries are supposed to be built on a mingw like environment. So is there any other way of running that program on a windows machine?

I am using the latest gfortran from MinGW and it seems I'm not getting my code compiled and run in 64bit. Is there a flag or compiler I should be using to take advantage of my 64bit version of Windows 10?
I have a simple C program that uses only basic stdio calls (single-threaded file I/O), which I compile on a Mac under clang.
Will this run under Windows? If not, how do I compile it to run under Windows?
You can use ELLCC, a clang based compiler toolchain, to cross compile Windows and Linux executables on a Mac.

I tried to use '-static', but then compiler can't find installed -lpng
You need to cross compile it. Run x86_64-w64-mingw32-gcc, included in package mingw64-x86_64-gcc-g++, in cygwin64 to cross compile a native windows 64bit executable. It is similar if you are in cygwin or to compile a 32bit executable.
However, without cygwin compatibility layer, a program using POSIX APIs cannot be compiled. If your program needs POSIX APIs, you have to compile with cygwin dependency.

I'm trying to compile a 32-bit C application on RHEL 7 64-bit using gcc 4.8. I'm getting a compiler error /usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory. What do I need to do to get 32 bit apps compiled and linked?
To get RHEL 7 64-bit to compile gcc 4.8 32-bit programs, you'll need to do two things.
Make sure all the 32-bit gcc 4.8 development tools are completely installed:
sudo yum install glibc-devel.i686 libgcc.i686 libstdc++-devel.i686 ncurses-devel.i686
Compile programs using the -m32 flag
gcc pgm.c -m32 -o pgm
