Error compiling DeSmuME

[JamesTheAwesomeDude]

I've been trying to get DeSmuME installed, and the versions in the official repos are incredibly stale, so I decided to compile it myself. Sadly, it's not working.

After installing the packages build-essential autoconf automake libgtk2.0-dev libglu1-mesa-dev libsdl1.2-dev libglade2-dev gettext zlib1g-dev libosmesa6-dev intltool libagg-dev libasound2-dev, as per the official instructions, I then extracted the source tarball, cd'ed into it, and ran ./configure. All well so far.

Unfortunately, make throws some errors...

What's the problem, and how do I fix it?

[searchfgold6789]

It feels like a bug in the source code, since line numbers are given. Perhaps you could try 0.9.8 instead. But you may end up actually going into the source code to fix this. Try opening the desmume-0.9.9/src/OGLRender.cpp file, scrolling down to the lines mentioned (161, 162, 164, 165, 168) and seeing if there's anything there that might make it work if you commented it out.
Here's a post that might contain a hint.

I couldn't get anything out of that thread, but I did look into OGLRender.cpp and here's a snippet of the code:

It may be something to do with your specific graphics hardware / drivers and exactly what OpenGL version and features it supports, it looks like the ABI does not require implementations to export that function and it's bad practice to rely on it

http://dri.freedesktop.org/wiki/glXG...erReturnsNULL/

There may be a workaround, it depends how much work you want to put into this

[JamesTheAwesomeDude]

I actually have no experience coding in C++ (I'm currently learning Python,) and I've never experimented with OpenGL, but after reading that article, I can't see why the reference to glXGetProcAddress would be undefined, since the function never returns null. Wouldn't any issues appear at runtime in that case? Why does it affect compilation?

[steeldriver]

sorry, I didn't mean that article specifically, just to point out that a particular vendor may chose not to define the function at all (or at least not externally) - which seems to be what you're experiencing

[steeldriver]

DISCLAIMER: THIS IS A COMPLETE SWAG, ABSOLUTELY NO WARRANTY EXPRESSED OR IMPLIED etc. etc. - but if you don't get any better suggestions you could try this

make clean
sed -i'.bak' 's/glXGetProcAddress/glXGetProcAddressARB/' src/OGLRender.h
make

The above just replaces the macro definition of INITOGLEXT (which is the immediate cause of your reported errors) with a - hopefully equivalent - reference to glXGetProcAddressARB
