<![CDATA[Qt5 (Fedora 18) - Cannot find -lGL]]>Hi all,

Today I downloaded and installed the latest Qt5.0.2 on a fresh Fedora 18 system. I am currently attempting to build and run the "camera" example application and am getting the following error:

@g++ -m64 -Wl,-rpath,/home/njozwiak/Qt5.0.2/5.0.2/gcc_64 -Wl,-rpath,/home/njozwiak/Qt5.0.2/5.0.2/gcc_64/lib -Wl,-rpath-link,/home/njozwiak/Qt5.0.2/5.0.2/gcc_64/lib -o camera main.o camera.o imagesettings.o videosettings.o moc_camera.o moc_imagesettings.o moc_videosettings.o -L/usr/X11R6/lib64 -L/home/njozwiak/Qt5.0.2/5.0.2/gcc_64/lib -lQt5MultimediaWidgets -lQt5Multimedia -lQt5Widgets -lQt5Network -lQt5Gui -lQt5Core -lGL -lpthread

As this is a brand new machine I ran an initial:

@sudo yum groupinstall "Development Tools"@

Then I attempted to install all relevant OpenGL packages. Here is what I have installed:

Any and all libGL* and libGL*-devel packages I can think of... I know I have to be missing something required, but I'm just not sure what. There is a similar post here: http://qt-project.org/forums/viewthread/22848. But the author never says what fixes it... and I have everything installed that pitonyak suggested for running in Fedora 18.

People keep saying installing the "libglu1-mesa-dev" package resolves this issue for them. But I do not see this package available in Fedora.

Any help would be appreciated.

Thanks,
Nate

For instance, if you have a libGL.so.1.2.0 in your /lib directory, then point a libGL.so symbolic link to it also in the /lib directory.

I assume that the first thing that you did was "yum whatprovides libGL"

Notice that I have both 64-bit and 32-bit versions of some of the libraries.

Don't know if it will help, but:
