While rebuilding STK for Mageia 4, I tried to include glxext.h to fix Mesa 10 changes :

{l Code}: {l Select All Code}

That is known problem, seems like those headers are curently broken upstream (from khronos):

http://lists.freedesktop.org/archives/m ... 50173.html
http://lists.freedesktop.org/archives/m ... 50177.html

That's the point : the headers fixed by Mesa need some fixes in STK code...

Same problem here, I get the exact same error.

I fixed the problem by deleting glext.h and symlining the system one instead.
But now I get an error from /usr/include/fribidi/fribidi-common.h about not finding glib.h.
I have the following glib.h : /usr/include/glib-2.0/glib.h

Any ideas?

I'm aware of the issue.

You can fix it by adding this line before #include "glext.h" in CIrrDeviceLinux.h/cpp :

"typedef void (APIENTRYP PFNGLBLENDEQUATIONPROC) (GLenum mode);"
I will come with a proper solution a bit later.

any progress on this? I need latest mesa for another game and i like testing latest stk from git. but applying this fix every time git updates is a bit annoying.

It's theorically fixed, I have mesa (git) on my system and I can build vanilla git stk.

Ok then maybe something else is eating my kittens!

to make sure i'm on the latest and greatest i did the following(please correct me if i did something wrong)

{l Code}: {l Select All Code}

# git reset --hard
# git pull
# cd cmake_build/
# make clean
# cmake ../
# make -j5


but it failes with following error:

{l Code}: {l Select All Code}

i'm currently using kubuntu 13.10 with the oibaf mesa drivers

I'm seeing the same thing as Toams on Arch Linux, with the latest released Mesa (10.0.3) library installed. It's quite possible they fixed this issue in Mesa 10.1, which will be released within the next few months.

Btw do you have sdl devel file ?
I don't, and irrlicht does not use the same include file if sdl is included.

I don't see SDL anywhere in the CMake build scripts for irrlicht. If having sdl libs makes a difference, that'd be a build script bug. We shouldn't be compiling support for it if we don't want it. I do have sdl libs though: Arch packages development files with the binary package.

If we haven't already integrated something like this, can we do so?
http://pkgs.fedoraproject.org/cgit/irrl ... sa10.patch

A tentative fix was committed for this, hopefully it should now work

Auria {l Wrote}:A tentative fix was committed for this, hopefully it should now work

Also shaders are now off by default. We had a lot of problems with GSoC students, who were not able to run their self-compiled version (because STK would crash before a config file is created, where the shaders could be disabled).

This will of course be changed later.

Cheers,
Joerg

I was having the same problem, but the current Git version a686c43 still doesn't compile for me

However, I checked my installed Mesa version and it is 10.0.1 (which is the packaged version in my distribution, Chakra Linux). Is that not supported?
