Install mingw, the official installer is broken, go to:
https://winlibs.com/#download-release
Download the UCRT runtime MinGW-w64 version.
Unzip it, in my case i have it in c:\mingw64
Add c:\mingw64\bin to your environment path variable.
Check that it's working, open a command prompt and type gcc --version
Now the pb lib code:
Code: Select all
EnableExplicit
ProcedureDLL add(a.l, b.l)
ProcedureReturn a + b
EndProcedure

The generated purebasic.c is:

We need the obj file from this c file, open a command prompt and go to the pb compilers folder, and use its gcc compiler, adapt the paths to the files, command line thanks to tool from idle.
gcc -O0 -fsigned-char -Wno-incompatible-pointer-types -Wno-overflow -Wno-int-conversion -c -o c:\pb\PureBasic.obj c:\pb\purebasic.c
This will create c:\pb\PureBasic.obj
Now use the ar.exe tool from the mingw installation to create a static lib:
ar rcs c:\pb\PureBasic.a c:\pb\PureBasic.obj
This will create the static lib c:\pb\PureBasic.a
Now use it from pb:
Code: Select all
Import "purebasic.a"
add(a.l, b.l) As "f_add"
EndImport
MessageRequester("", Str(add(2,3)))
