I have a Qt C++ application that includes a third-party library (along with its .h header file). However, when I set QMAKE_CCFLAGS += -std=c++11
and CONFIG += c++11
, I get undefined reference for function calls to this third-party library.
It compiles without c++11 flags.
Is there a way to resolve this?
This is qmake specific when using c++11
flags in the qmake configuration. The DLL file is linked with qmake LIBS and is compiling without the c++11 qmake configuration flag.
Once I set:
QMAKE_CXXFLAGS += -std=c++11
CONFIG += c++11
compiling gives me unresolved symbol errors.
Tried the solution for this answer and it resulted in a successful compilation.
It works when I add
Qt 5.4.1 MinGW 4.9.1 32bit
