nimforum mirror - Trouble getting cross compilation to work

JohnLuck (orginal) [2021-05-06T11:49:21+02:00] view original

I am on mac and trying to compile dynamic libraries for Windows (for a game im making in Godot). Right now my solution to compiling involves a USB stick and rebooting...

I try to compile for windows like so: nim c -d:mingw my_file.nim

I get: (i installed mingw with brew) 'vccexe.exe /c --platform:amd64 /nologo -DWIN32_LEAN_AND_MEAN /Zi /FS /Od /I/Users/stefanlund/.choosenim/toolchains/nim-1.4.4/lib /I/Users/projects/turing_complete/nim /nologo /Fo'/Users/stefanlund/.nimcachewindowsamd64/stdlib_sharedlist.nim.c.obj' '/Users/stefanlund/.nimcachewindowsamd64/stdlib_sharedlist.nim.c'' failed with exit code: 127

I should mention I have a bunch of arguments in a .cfg file, but I would guess they aren't related:

--path:"$projectdir"

--app:lib

-d:useRealtimeGc

--noMain

--warning[LockLevel]:off

--threads:on

--tlsEmulation:off

Any help welcome.

vccexe.exe is visual c or? Seems that your config does not use mingw.

from the nim compiler's nim.cfg:

@if unix and mingw:
  # Cross compile for Windows from Linux/OSX using MinGW
  i386.windows.gcc.exe = "i686-w64-mingw32-gcc"
  i386.windows.gcc.linkerexe = "i686-w64-mingw32-gcc"
  i386.windows.gcc.cpp.exe = "i686-w64-mingw32-g++"
  i386.windows.gcc.cpp.linkerexe = "i686-w64-mingw32-g++"
  
  amd64.windows.gcc.exe = "x86_64-w64-mingw32-gcc"
  amd64.windows.gcc.linkerexe = "x86_64-w64-mingw32-gcc"
  amd64.windows.gcc.cpp.exe = "x86_64-w64-mingw32-g++"
  amd64.windows.gcc.cpp.linkerexe = "x86_64-w64-mingw32-g++"
  
  @if macosx:
    i386.windows.gcc.path = "/usr/local/bin"
    amd64.windows.gcc.path = "/usr/local/bin"
  @else:
    i386.windows.gcc.path = "/usr/bin"
    amd64.windows.gcc.path = "/usr/bin"
  @end
  
  os = windows
  
  gcc.options.linker = ""
  gcc.cpp.options.linker = ""
@end

Also you can give the flags "--hint:cc --hint:link" to see log details about the used toolchain

Here's my working setup from my min project:

# https://blog.filippo.io/easy-windows-and-linux-cross-compilers-for-macos/

switch("amd64.windows.gcc.path", "/usr/local/bin")
switch("amd64.windows.gcc.exe", "x86_64-w64-mingw32-gcc")
switch("amd64.windows.gcc.linkerexe", "x86_64-w64-mingw32-gcc")

switch("amd64.linux.gcc.path", "/usr/local/bin")
switch("amd64.linux.gcc.exe", "x86_64-linux-musl-gcc")
switch("amd64.linux.gcc.linkerexe", "x86_64-linux-musl-gcc")

The link in the comment is the key really.

However, I recently stopped cross compiling locally and I am now using a GitHub action... less hassle overall:

This one did the trick for me, thank you!
