    Default Compile flags in QT

    Hi I think I need to change compile flags for my QT project since I after adding this line of code:
    typedef DLLEXPORT BOOL (__stdcall *sInit_PT)(void);
    I get the error:
    simcan.cpp:37: warning: 'dllexport' attribute ignored

    I think the solution would be to add the flag:
    QMAKE_CXXFLAGS= "-fkeep-inline-functions"

    But how do I add this flag? I tries adding it to the makefile. But no change. There has to be a way to add compile flags in creator?
    Very grateful for any tips.

    In your project file, add
    Qt Code:
    1. QMAKE_CXXFLAGS+=-fkeep-inline-functions

    Can't say if this will solve your issue though.

    This didnĀ“t solve the problem. This error is disabling me from using functionality defined in the dll. So my code is:
    #define DLLEXPORT __declspec(dllexport)
    typedef DLLEXPORT BOOL (__stdcall *sInit_PT)(void);
    Generates the following error:
    simcan.cpp:38: warning: 'dllexport' attribute ignored

    Any ideas for a solution?
