Use FLTK libraries with QtCreator

[amleto]

why dont you ask on a fltk forum? This is a Qt programming forum, and your question has nothing to do with qt programming.

Ok, I wrote in the forum FLTK - general. Let's see what they tell me. But then you have to act on the file .pro of QtCreator to build the project

Found the solution. Having the libraries FLTK 1.3.1 compiled (it can be easily done using the shell of MSYS (rxvt) with MinGW 4.6.2), this is to give the MSYS (rxvt) shell prompt the following command:

fltk-config --ldstaticflags

fltk-config --ldstaticflags

in this way we obtain the flags necessary for the compilation of any example of using FLTK MinGW and consequently amche our beloved Qt Creator 2.6.0
In my case for example I got:

-mwindows /usr/local/lib/libfltk.a -lole32 -luuid -lcomctl32

-mwindows /usr/local/lib/libfltk.a -lole32 -luuid -lcomctl32

Please note that:

/usr/local/

/usr/local/

To copy to clipboard, switch view to plain text mode 

is in

C:\MinGW\msys\1.0\local

C:\MinGW\msys\1.0\local

To copy to clipboard, switch view to plain text mode 

So in the project file of Qt we get:

#------------------------------------------------
#
# Uso librerie FLTK 1.3.1
#
#------------------------------------------------
INCLUDEPATH += C:/MinGW/include
 
LIBS += -mwindows C:/MinGW/lib/libfltk.a \
        C:/MinGW/lib/libfltk_forms.a \
        C:/MinGW/lib/libfltk_gl.a \
        C:/MinGW/lib/libfltk_images.a \
        C:/MinGW/lib/libfltk_jpeg.a \
        C:/MinGW/lib/libfltk_png.a \
        C:/MinGW/lib/libfltk_z.a \
        -lole32 -luuid -lcomctl32

#------------------------------------------------
#
# Uso librerie FLTK 1.3.1
#
#------------------------------------------------
INCLUDEPATH += C:/MinGW/include

LIBS += -mwindows C:/MinGW/lib/libfltk.a \
        C:/MinGW/lib/libfltk_forms.a \
        C:/MinGW/lib/libfltk_gl.a \
        C:/MinGW/lib/libfltk_images.a \
        C:/MinGW/lib/libfltk_jpeg.a \
        C:/MinGW/lib/libfltk_png.a \
        C:/MinGW/lib/libfltk_z.a \
        -lole32 -luuid -lcomctl32

For the curious here is the procedure to follow to compile the libraries FLTK 1.3.1 with MinGW 4.6.2 using MSYS (rxvt):
1- copy the file fltk-1.3.1-source.tar.gz in /home/your-username/ of msys\1.0\ then give the command to
MSYS shell (rxvt):

tar xvzf fltk-1.3.1-source.tar.gz

tar xvzf fltk-1.3.1-source.tar.gz

To copy to clipboard, switch view to plain text mode 

2-

cd fltk-1.3.1

cd fltk-1.3.1

To copy to clipboard, switch view to plain text mode 

3-

./configure & make & make install

./configure & make & make install

To copy to clipboard, switch view to plain text mode 

will be installed in /usr/local/lib, /usr/local/include/FL, /usr/local/bin, /usr/local/share. Please note that /usr/local is C:\MinGW\msys\1.0\local
Have fun with FLTK
