I recently switched to Xubuntu 15.04 64-bit (from Debian 32-bit) and had some problems with compiling Irrlicht.
I already have all the source dependencies, I used:
Code: Select all
sudo apt-get build-dep irrlicht
After unzipping the Irrlicht 1.8.1 source archive (from http://irrlicht.sourceforge.net/downloads/) I simply run make -j4 in source/Irrlicht/
make gives me this error:

Irrlicht compiles fine and I have libIrrlicht.a in ../../libs/Linux.
When I buildAllExamples.sh however:
Code: Select all

collect2: error: ld returned 1 exit status

make: *** [all_linux] Error 1
To fix this I comment out glXSwapIntervalSGI(interval); in COpenGLExtensionHandler.h (Line 2540) and recompile Irrlicht.
Then I can compile the examples and
everything works, or so it appears...Have I come across a genuine bug or have I misconfigured something? Will my n00b fix break something else down the track?
I'm running Xubuntu 15.04 64-bit.
I have an Nvidia GeForce GTX 750, using driver version 346.59 from the standard Ubuntu Repo.
