QWT 5.1.0 installation with eclipse

[kokasurfer]

Hello!


I have a problem concerning the installation of Qwt 5.1.0.
I installed qwt with make, make install
and executed ldconfig -v to include the library. The -lqwt is linked.
I also set the include path in my eclipse project /usr/local/qwt-5.1.0/include
and I added INCLUDEPATH += /usr/lib/qwt-5.1.0/include
LIBS += -L /usr/lib/qwt-5.1.0/lib -lqwt
in my .pro-file.

But I can't compile my project because of the fault:
"qwt.h: No such file or directory "

What have I forgotten?
Please help me.

Thanks in advance,
kokasurfer

You need to include the location for qwt headers also.
Your make file should include the directory /usr/include/qwt-qt4 if using qwt built for qt4 or simply /usr/include/qwt

Your makefile would have an option INCPATH =

in that add /usr/include/qwt-qt4 then your code will compile.
