Thread: OpenGL programming / questions about extensions

hi all,

i'm playing little bit opengl programming on linux , i've simple questions.

glxinfo gives me following opengl version:

opengl version string: 2.1 mesa 7.11

i guess means system support opengl 2.1 using mesa implementation. can confirm correct ?

the, if @ gl/gl.h /usr/include found like:

#define gl_version_1_1 1
#define gl_version_1_2 1
#define gl_version_1_3 1
#define gl_arb_imaging 1

so gl_version_xx not defined 1.4, 1.5, 2.0. question is, why header file not include definitions gl versions 2.0 (at least) ?
i'm supposed change gl/gl.h header file more appropriate ?

please note if nothing sort of linker warning:

/usr/bin/ld: warning: type of symbol `glblendfuncseparate' changed 2 1 in ../ogld/libogld.a(ogldif.o)

and guess related missing declarations opengl 1.4+.

information, i'm running on standard ubuntu installation oneiric. graphical card in ati radeon mobility 2300 , i'm using driver provided x.org, here more informations glxinfo:

opengl vendor string: x.org r300 project
opengl renderer string: gallium 0.4 on ati rv515
opengl version string: 2.1 mesa 7.11
opengl shading language version string: 1.20

any appreciated. in advance.
