You’re using older code with newer libs, the fftw libs changed a little since 3.6 and the 3.6 codebase doesn’t know about that (how could it) use these libs rather than the ones you have

svn co


yeah, I repalce fftw3 lib by (bf-blender - Revision 63481: /tags/blender-3.5-release/lib/win64_vc15/fftw3) and it works fine now, thank you!

In addition, is there any files that I can edit to control the svn to get the older libs?

Just manually grabbing the whole folder with the command i showed you is the easiest way to go about that

but “libfftw.lib” is not in blender-3.6-release/lib/win64_vc15/fftw3 either, I find it in blender-3.5-release/lib/win64_vc15/fftw3. I also try blender-3.6-release/lib/win64_vc15/fftw3 and it failed too.

by the way, problem is solved now, thanks a lot!

I’m not sure how that could happen, this code in 3.6 allows it to be building against both 3.6 and 3.5 libs, i’d validate your code matches this snippet.
