Hi all…
I’m still having problems with this. I can get Flext to compile and produce a static library “.a” file under both MSYS and from the DOS command prompt using MINGW32…
However, whatever I try I always end up at the same place which is a bunch of linker errors relating to undefined Pd references:

collect2.exe: error: ld returned 1 exit status
I remember there was a linker flag to suppress these on Linux, but I don’t think it’s available on Windows…
Any clues?

However, I think this will break builds on Windows when FLEXT_INLINE is defined. A better solution would be to either remove FLEXT_INLINE entirely or use the FLEXT_TEMPLATE macros, but I couldn’t really understand those or get them to work.
