Problems linking gsl 2.1 with Qt

I'm using Qt 5.8 and gsl 2.1 (compiled with cygwin64). This is what I use in the .pro file to link gsl:

INCLUDEPATH+=C:/gsl/include/
INCLUDEPATH += C:/gsl/LIBS
LIBS += -LC:/gsl/lib -lgsl -lgslcblas -lm

When I include the headers and compile, I don't have any problem, even when I declare and object. But when I try to use any function I get this error:

C:\Users\CIFAS-1\untitled4\mainwindow.cpp:9: error: undefined reference to `gsl_matrix_alloc'.
Solution

  • I already solve the problem, I found a compiled version of gsl for mingw32 here https://code.google.com/archive/p/gsl-w32/downloads, it is another version but works great.
