parrot does not build if library glfw is installed

[wagnerf]

i'm building parrot (for rakudo) on my machine.

i'm running :

git clone  git://github.com/rakudo/rakudo.git

perl Configure.pl --gen-parrot

it then fails with :

gen::opengl - Generating OpenGL bindings... step gen::opengl died during execution: 'GLFW_KEY_LAST' is defined as 'GLFW_KEY_KP_ENTER', but no 'GLFW_KEY_KP_ENTER' has been defined at config/gen/opengl.pm line 596.

at Configure.pl line 75

I grepped in /usr/include for GLFW_KEY_LAST which is defined in /usr/include/GL/glfw.h

removing this library enables me to build everything correctly

so I think there are 2 problems here : a) this header file should not be parsed ? b) this header file is correct but somehow is not parsed correctly

cc-ing some Parrot developers who have worked on config/gen/opengl.pm.

wagnerf, please attach a tarball of your /usr/include/GL/ ... I can usually diagnose and correct the parsing problem from that.

As background, the GL header files are not parsed using a real C header parser -- so even though everything works most of the time, whenever a vendor does something really tricky, the "parser" has to be manually tweaked not to trip over it. :-(

here is the header file causing problems :

 http://glfw.svn.sourceforge.net/viewvc/glfw/trunk/include/GL/glfw.h?revision=938&view=markup

I guess fixing the parser should not be too hard but i'm not sure this file should be parsed

As of r42952:

1. The parser has been improved to handle the define errors, so only warnings remain. 2. But I'm force-skipping glfw.h anyway. It's a GLUT "replacement", and really requires a whole pile of work to actually support (as opposed to merely not error out on).

Please open a new ticket if you actually need to *use* GLFW from Parrot; I'm closing this one as the original problem (inability to configure parrot when GLFW is merely installed on the system) has been fixed.
