Cannot compile quazip 0.7.3 with Qt 5.10.1 MinGW

[bam500]

I am trying to compile the Quazip project version 0.7.3 with Qt 5.10.1 MinGW 32 bits on Windows, but I get the following errors :

When I Ctrl+click on an undefined function like adler32 it points to C:\Qt\Tools\mingw530_32\i686-w64-mingw32\include
It seems that I need to link with the zlib.dll but I don't find it in Qt directories... and I have read that in Qt 5.10.1 it is integrated in QtCore.dll

@bam500 Did you use the built in qt zlib or a system one? My guess would be built in since you are on windows.

Either way just add -lz to your linker line in your build and it should find it.

[bam500]

Yes I use the builtin Qt zlib

Thank you @ambershark I have added the following line in the quazip project .pro :

LIBS += -lz

Now I can compile it.
