Unsolved Why default Qt linker cannot link to libraries
-
i'am developing a project and every external libraries I trie to use the same errors appears...
Unsolved reference, the linker cannot find the library that a specifie in the LIBS variable of os .pro file.Below my .pro file and the linker error:
.pro file

@francoatmega said in Why default Qt linker cannot link to libraries:
LIBS += \ -LD:\1libs \
Perhaps you meant to write:
-LD:/1libs \
You don't use backslashes but forward slashes with qmake.

@kshegunov Same error bro...
And I was looking the the mingw32-make use backslash:mingw32-make[1]: Entering directory 'C:/Users/francoatmega/Documents/build-WanGlacier2-Desktop_Qt_5_9_1_MinGW_32bit-Debug'

What do you think?

This is most definitely it. You can't mix compilers, you have to compile your app with a matching compiler or your library with mingw.
