redefinition of typedef errors in unofficial opengl sdk

Question

using the arcsynthesis opengl tutorial and I'm trying to build the unofficial sdk that the examples use, per the instructions here: http://glsdk.sourceforge.net/docs/html/pg_build.html#page_build_libs . (I'm using code::blocks and the gnu gcc compiler, and 0.4.0 of the unofficial sdk) It's not working, I get this error:

C:\libs\c\glsdk_0.4.0\glload\source\wgll_ext_base.h|29|error: redefinition of typedef 'GLenum'|

C:\libs\c\glsdk_0.4.0\glload\source\gll_gl_ext_base.h|27|note: previous declaration of 'GLenum' was here|

repeated several times for other sybmols, including GLBoolean, GLBitField, etc. since I'm pretty sure I'm not supposed to fix this by actually modifying the sdk I'm assuming it's a build/linker muckup on my part, but I'm only using the workspace that premake4 generated, not rolling my own or anything.

The Tutorial distribution comes with the SDK; it's in the folder called glsdk. You aren't supposed to download the SDK from the SDK site. The Tutorial build instruction explain how to build it.

Also, the 0.4.0 version is somewhat old; there was a build problem with Code::Blocks (and probably other builds). The most recent release is 0.4.2, which should work.

Answer 2

1. Follow the premake instructions for vs2010
2. In Code::Blocks, go to file-->import project-->Microsoft Visual Studio Solution
3. Import openglsdk.sln from the directory where you placed the sdk files

Now the sdk will be available as a workspace in Code::Blocks. As of this post, the Unofficial OpenGL SDK is version 0.50. I answered this with step by step directions because I couldn't find any for Code::Blocks, and some people just beginning to learn OpenGL may need a little guidance.
