Right, and the flext build system is what I’m using here. Current master branch tip. In fact I reversed the order of -lflext-pd_s -lpd so that flext links first, otherwise I get a *lot* more linker errors.
I’ll investigate that import library concept.

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.
