My memory with Windows is vanishing, but as for as i remember, there is a way to generate an "import library" from the exported pd symbols, which can then be used for linking.
I thought that this is actually integrated in the flext build system.

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.
