Post subject:  [solved] Compiling problems with GCC 4.3.0
Essentially GCC 4.3.0 does not include c-headers when including C++ headers.
Hence, it breaks compatibility with Horde3d as it relies on this fact.

Here's some patches to fix it.

Thanks for this advice. As I don't have a GCC 4.3.0 configuration running, I can't test if it's really necessary to add cstdlib and cstring to egPrerequisities.h.

Can you try if the following patch is working, too?

This problem not in gcc! This specific for new glibc(2.8).
On gcc 4.3.1 all ok.

Yes it is; I'm running gcc 4.3.1 + glibc 2.8, and the include problems are still there. I will apply the patch and see what happens.

Read the chapter "Header dependency cleanup" on this => http://gcc.gnu.org/gcc-4.3/porting_to.html page. Seems like they are implementing stuff that has been nailed down for C++0X.

Yes Volker, your patch works too.
Maybe the topic should be renamed to "Compiling problems with glibc" ?

:P.

For my system:
Arch64

gcc 4.3.1 (updated today)
glibc 2.8

It is necessary to apply the patches.

Ok, I commited it to the SourceForge SVN

Thank you :) I can confirm that the project now builds straight from svn on gcc 4.3.1 (all I need to add is the -msse2 flag).
