shaunidiot commented 11 years ago

I encountered a problem while building on Fedora. I've G++, Qt libraries all installed. /usr/bin/ld: cannot find -lGL

[root@localhost build]# make g++ -Wl,-O1 -Wl,-rpath,/opt/Qt5.1.1/5.1.1/gcc_64 -Wl,- rpath,/opt/Qt5.1.1/5.1.1/gcc_64/lib -o TOX-Qt-GUI [All the files] -lsodium - L/opt/Qt5.1.1/5.1.1/gcc_64/lib -lQt5Widgets -lQt5Gui -lQt5Core -lGL -lpthread 

/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
make: *** [TOX-Qt-GUI] Error 1```

Thanks in advance!

seems missing OpenGL

shaunidiot commented 11 years ago

Sorry sorry, I'm pretty new to this. I've researched online and was told to check glxinfo | grep rendering which returned direct rendering: Yes, which I'm pretty sure it means OpenGL was installed. glxgears also showed the gears animation. Also, I've tried sudo yum install mesa-dri-drivers mesa-libGL and rebooted, yet the problem still persist. Any help with this? Thank you!

INSTALL.md

If Qt complains about missing GL library, install libgl-dev package.

@nordbjerg Thank you so much! Manage to install the library and it works now (after some tinkering)! Appreciate your help.

@nurupo Sorry! I tried to yum install that package and it doesn't work for my case (using Fedora). @nordbjerg 's suggestion works! Thanks nonetheless!

@shaunidiot libgl-dev is usually an alias on some of package repositories, which, when asked for, would suggest you appropriate GL dev library, such as mesa-libGL-devel. If not, you could just search for such library yourself, since you know that you need to install GL dev library.
