Project ERROR: Unknown module(s) in QT: opengl

Dear Developers,

I have tried to compile "qwt-6.1.4" code using qmake as shown below

Code:

---

sudo /opt/Qt5_7_1/qt571-bbbhf/bin/qmake qwt.pro

---

and then gave

Code:

---

sudo make

---

command.

After giving make command I got following error:

Code:

---

cd src/ && ( test -e Makefile || /opt/Qt5_7_1/qt571-bbbhf/bin/qmake /usr/local/qwt-6.1.4/src/src.pro -o Makefile ) && make -f Makefile 
Project ERROR: Unknown module(s) in QT: opengl
Makefile:45: recipe for target 'sub-src-make_first-ordered' failed
make: *** [sub-src-make_first-ordered] Error 3

I would be grateful to you if you please exaplain me how can I solve error given above. please inform me if you need any other information from me.


Thanks and regards

You are trying to build Qwt with OpenGL support, while your Qt build had been built without.
Actually this is a situation the Qwt project files could autodetect, but for the moment you have to resolve it on your side by:

• building Qt with OpenGL support
• or disabling OpenGL for Qwt in qwtconfig.pri

Thank you very much uwe it has helped me :). As I do not have any knowledge of OpenGl and new to QWT. I would be grateful to you if you please inform me whether I can make 2D line graphs from data obtained from sensors without using OpenGL ? ..Many thanks :)
