NVIDIA driver breaks DeSmuME compilation

[garyl]

I heard NVIDIA driver broke DeSmuME compilation, and it's true.

1. Get desmume-0.9.2-1.
http://sourceforge.net/project/downl....gz&a=52243207

2. Extract desmume and build it.
$ tar zxf desmume-0.9.2-1.tar.gz
$ cd desmume-0.9.2-1
$ ./configure --prefix=/usr/ --libdir=/usr/lib64/
$ make -j3

[with NVIDIA-Linux-x86_64-185.18.14]

OGLRender.cpp: In function ‘char OGLInit()’:
OGLRender.cpp:470: error: ‘glActiveTexture’ was not declared in this scope
OGLRender.cpp: In function ‘void setTexture(unsigned int, unsigned int)’:
OGLRender.cpp:535: error: ‘glActiveTexture’ was not declared in this scope
OGLRender.cpp: In function ‘void OGLRender()’:
OGLRender.cpp:698: error: ‘glActiveTexture’ was not declared in this scope
make[2]: *** [OGLRender.o] Error 1

[without NVIDIA driver]
# sh NVIDIA-Linux-x86_64-185.18.14-pkg2.run --uninstall
# exit
$ ./configure --prefix=/usr/ --libdir=/usr/lib64/
$ make -j3
=> I can build it without errors.

I know DeSmuME isn't important for most users, but the same thing might
happen to other softwares.

Hi,

Seems to be the same bug as openoffice.

Use "-DGL_GLEXT_PROTOTYPES" in your CFLAGS, and it should be OK

guilc, thanks for your quick reply.

and it doesn't work for me either.

I added "-DGL_GLEXT_PROTOTYPES" to desmume-0.9.2-1/Makefile and
desmume-0.9.2-1/src/Makefile.

I can confirm that behaviour, and that -DGL_GLEXT_PROTOTYPES doesn't fix it

It looks like the configure script for this program incorrectly ignores the CFLAGS configure parameter. It also appears to have support for getting the glActiveTexture function via the extension mechanism, but incorrectly disables that code when GL_VERSION_1_3 is defined. It should either define GL_GLEXT_PROTOTYPES or make the OGLEXT/INITOGLEXT code unconditional.
