x86_64-w64-mingw32-ld: cannot find -lz

If I check the /usr/x86_64-w64-mingw32/lib/ path in dolphin or konqueror I do find the libz.a and libz.dll.a files right there. I know they are not supposed to be included with the mingw packages, but the same happens to any library that is included by default.

Thereafter I came up with the idea that creating pc files myself would probably fix this situation so I did. Even if pkg-config and cmake say they have found the packages (including binaries, included header files, and libraries), the linker just denies they can be found anywhere. Even if it was a crazy idea, I used the default ld to try compile my custom project and it did find all of the specified libraries without any issues. Of course the result was not good at all for ld thought it was linking common Linux libraries XD

By the way, I also exported a custom location for the pkg-config files and double checked it with echo $PKG_CONFIG_PATH, and still mingw ld was unable to find the packages =_=

It seems that ld is using “no” as a sysroot. The interesting part here is in the “large script” you removed; could you at least tell me what the “SEARCH_DIR” setting is, near the start of the script?
