Compilation errors, help please

[theduck]

Hey,

I'm trying to compile the HelloWorld example on Linux. I previously had it working
until I re-installed because I screwed something up. :P

Now when I go to the HelloWorld directory, and execute a make there, I get:

Code: Select all

me@linux:~/Irrlicht/examples/01.HelloWorld> make
g++ main.cpp -o example -I"../../include" -I"/usr/X11R6/include" -L"/usr/X11R6/lib" -L"../../lib/Linux" -lIrrlicht -lGL -lGLU -lXxf86vm -lXext -lX11
/usr/lib/gcc-lib/i586-suse-linux/3.3.4/../../../../i586-suse-linux/bin/ld: cannot find -lGLU
collect2: ld returned 1 exit status
make: *** [all] Error 1

Apparently it can't find -lGLU. I never got this last time, and now I'm getting it (obvisouly) and its making me mad.

I've been using C# lately, and I just came back to C++ after a long time off. What do I do? ;)

Thanks in advance.


[EDIT]: I just did a search, and somehow I don't have lGLU on my system. 0.o Do I recompile it from source or get the .a file from the internet? Then I'll hopefully be on my way.

You shouldn't need to download anything.
Make sure you are setting up your linking your libraries properly.
what compiler are you using?

first try to use /usr/lib and /usr/include since /usr/X11R6/bla is obsolete - works for me.

if that does not work, check in /usr/lib if libGLU.so/libGLU.so.1 or something like that exists. when not, install glu with the suse package management. or if that fails get a .rpm file out of the net, you can find them on rpmseek.com for example.

good luck!

Just had to install the mesa-devel rpm, thanks a lot guys
Now time to get crackin!

Also what was cool this time, is that I didn't have to re-compile the engine AND
I also get the GL Extensions that didn't work last time! :O Yay! ^-^

are you sure the mesa-stuff isnt too slow? as far as i know (could be wrong) mesa is using software opengl which is _very_ slow.

but i dont really know SuSe and i usually never use rpm packages.
