This contains the barest minimum needed to emulate bcc32.exe and tlink32.exe. Other utilities such as tdump.exe might work.

NOTES

CreateProcess isn't implemented, so bcc32 cannot invoke the linker directly. You need to manually run the compiler with -c and the linker separately.

C: is emulated to be this Python module's directory, and Z: is the current working directory. You'll need to manually specify -I and -L as well because it doesn't seem to load the .cfg files for some reason.

Note that the commas in tlink32 are important! It is very much not *nix-style tooling.

Example

$ cat test.c
#define WIN32_LEAN_AND_MEAN
#include <windows.h>

int __stdcall WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    MessageBox(0, "Hello world!", "OwO?", 0);
    return 42;
}

$ ./bcc32 -IC:\\BC5\\INCLUDE -c test.c
$ ./tlink32 -LC:\\BC5\\LIB -c -aa -Tpe c0w32.obj test.obj , test.exe ,, import32.lib cw32.lib

$ file test.exe
test.exe: PE32 executable (GUI) Intel 80386, for MS Windows
