在Qt中使用SOIL库时出错

Question

I get the following error ":-1: error: cannot find -llibSOIL" when trying to add SOIL. Here are the steps I am doing:

1) Add the following to .pro file

SOILPATH = "/home/swayu/Desktop/color quantization/Simple OpenGL Image Library"
INCLUDEPATH += "$${SOILPATH}/src"
LIBS += -L"$$(SOILPATH)/lib" -llibSOIL

*libSOIL.a file resides in the lib folder but still I am getting the above error.

2) include soil.h in the cpp file where I want to use the functionality offered by this library.

Answer 1

Try:

LIBS += "-L$${SOILPATH}/lib" -llibSOIL

rather than:

LIBS += -L"$$(SOILPATH)/lib" -llibSOIL

According to Qt doc , that's the right syntax (quotes are inclusing -L and use curly braces for the path variable "SOILPATH").
