I have installed leveldb from here: https://github.com/Microsoft/vcpkg/tree/master/ports/leveldb. Now I get errors when compiling with pip install plyvel

    _plyvel.obj : warning LNK4197: export 'PyInit__plyvel' specified multiple ti

UPD. Solved. The problem was library shlwapi.lib, which containts function PathFileExists, is not linked during installing through pip. Finished with an ugly hack with merging it into leveldb.lib: lib.exe /OUT:c.lib leveldb.lib ShLwApi.Lib

is there anything that should change inside plyvel?

hi @iNomaD , i'm facing the same problem, but am not sure how to implement your solution. would it be possible to explain which directory i need to go to to find lib.exe? thanks and apologies, real noob here
