hello,

i just downloaded vegastrike and data4.x using cvs and followed the steps in the howto to compile it. running ./configure i get this warning:

checking for GL/gl.h... yes
checking GL/glext.h usability... no
checking GL/glext.h presence... yes
configure: WARNING: GL/glext.h: present but cannot be compiled
configure: WARNING: GL/glext.h: check for missing prerequisite headers?
configure: WARNING: GL/glext.h: see the Autoconf documentation
configure: WARNING: GL/glext.h: section "Present But Cannot Be Compiled"
configure: WARNING: GL/glext.h: proceeding with the preprocessor's result

configure: WARNING: ## ------------------------------------- ##
configure: WARNING: ## Report this to the vegastrike lists. ##
configure: WARNING: ## ------------------------------------- ##
checking for GL/glext.h... yes
checking whether glext.h is recent enough... yes

the full config.log can be viewed here: http://www.deep-space.at/misc/config.log

please tell me what i should do about this warning.

i'm going to try to compile vegastrike despite the warning and will post the result.

hello again,

a "make" produced the following error:
make[3]: Entering directory `/root/vegastrike/vegastrike/src/gldrv'
...
...

seems to be the same error as in this post http://vegastrike.sourceforge.net/forum ... .php?t=952

i downloaded this version of glext http://cvs1.nvidia.com/inc/GL/glext.h
and get the same error.

oops
sorry haven't read all of that post. i missed the part about the diff of gl_globals.h.
sorry for posting before reading

well, it's me posting again

i checked my vegastrike/src/gldrv/gl_globals.h file and it has the correct lines,
but running configure still gives that warning about glext.h although i replaced it with the file from nvidia.
i tried to compile again AND IT WORKS !!

i'm sorry for opening a new topic that is now no longer needed, but maybe someone is interested in that warning above.

P.S.: vegastrike is a great game !

I ran into this same problem a while ago... it seems pretty common.
