Duplicated symbols when linking with minizip #169

Copy link

When using v1.4

One of our dependencies is using minizip. This creates a problem of symbol duplication:

duplicate symbol '_call_zopen64' in:
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libquazip1-qt6d.a(qioapi.cpp.o)
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libminizip.a(ioapi.c.o)
duplicate symbol '_call_ztell64' in:
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libquazip1-qt6d.a(qioapi.cpp.o)
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libminizip.a(ioapi.c.o)
duplicate symbol '_call_zseek64' in:
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libquazip1-qt6d.a(qioapi.cpp.o)
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libminizip.a(ioapi.c.o)
duplicate symbol '_fill_zlib_filefunc64_32_def_from_filefunc32' in:
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libquazip1-qt6d.a(qioapi.cpp.o)
    /Users/Shared/vcpkg/installed/arm64-osx/debug/lib/libminizip.a(ioapi.c.o)

Any way to isolate the definitions copied from minizip or to use minizip instead?

Thanks,

David

Renaming this functions will do the trick:

  • call_zseek64
  • call_zopen64
  • call_ztell64
  • fill_zlib_filefunc64_32_def_from_filefunc32

@naskin-gmg
adds prefix to some of the minizip symbols
57cf220 
quazip has copy of minizip sources,
when any target is statically linked both to minizip and quazip targets this creates conflict.
Depending on the linker this can produce an error or one of the implementation will be silently discarded.
