276 | =head2 GLX SUPPORT |
|
|
277 | |
|
|
278 | Due to the sad state that OpenGL support is in in Perl (mostly the OpenGL |
|
|
279 | module, which has little to no documentation and has little to no support |
|
|
280 | for glx), this module, as a special extension, treats context creation |
|
|
281 | properties C<OpenCL::GLX_DISPLAY_KHR> and C<OpenCL::GL_CONTEXT_KHR> |
|
|
282 | specially: If either or both of these are C<undef>, then the OpenCL |
|
|
283 | module tries to dynamically resolve C<glxGetCurrentDisplay> and |
|
|
284 | C<glxGetCurrentContext>, call these functions and use their return values |
|
|
285 | instead. |
|
|
286 | |
|
|
287 | For this to work, the OpenGL library must be loaded, a GLX context must |
|
|
288 | have been created and be made current, and C<dlsym> must be available and |
|
|
289 | capable of finding the function via C<RTLD_DEFAULT>. |
