Help with Celestia on FreeBSD 5

[Richard]

Hi,
I'm trying to compile celestia 1.3 on Freebsd 5.0 and get the following error when running configure:

checking GL/gl.h usability... yes
checking GL/gl.h presence... no
configure: WARNING: GL/gl.h: accepted by the compiler, rejected by the preprocessor!
configure: WARNING: GL/gl.h: proceeding with the preprocessor's result
configure: WARNING: ## ------------------------------------ ##
configure: WARNING: ## Report this to bug-autoconf@gnu.org. ##
configure: WARNING: ## ------------------------------------ ##
checking for GL/gl.h... no

I have mesa installed and gl.h is present. I have run configure with
--with-gl-inc=/usr/X11R6/include/GL but get the same error.
Any help appreciated.
Thanks
configure: error: No gl.h found. See INSTALL file for ddetails about how to correct this problem.

Check for the exact error at the end of config.log, you should see there the compilation command that failed and a more detailed error message.

Thanks. The relevant bit of the config log is:

configure:20006: $? = 0
configure:20016: result: yes
configure:20020: checking GL/gl.h presence
configure:20031: gcc -E conftest.c
In file included from configure:20047:
/usr/include/GL/gl.h:2245:22: GL/glext.h: No such file or directory
configure:20037: $? = 1
configure: failed program was:
| #line 20022 "configure"

There then follows confdefs.h etc and a list of variables which I can copy if it would help but there are quite a few lines.

I think that's related to the not POSIX compliant use of test salo found while compiling Celestia on NetBSD, he's posted a patch, you should try and apply it. He has posted another patch that you'll probably need here.
