Commit: 8623d75b468ff1a495a326cf74ca6d61f1ee4ce7 Author: Antony Riakiotakis Date: Sun Nov 22 18:14:16 2015 +0100 Branches: master https://developer.blender.org/rB8623d75b468ff1a495a326cf74ca6d61f1ee4ce7
Add check for OpenGL version 2.1 on linux. Unfortunately there's no easy way to show a messagebox here, so just print a warning on fstderr and exit. If we don't call exit() here we get crashes on other blender systems (python, opensubdiv) and it can get tricky to track the initialization state here, so just using exit() should do the trick for now. =================================================================== M intern/ghost/intern/GHOST_ContextGLX.cpp =================================================================== diff --git a/intern/ghost/intern/GHOST_ContextGLX.cpp b/intern/ghost/intern/GHOST_ContextGLX.cpp index 0ee8da1..8e46c95 100644 --- a/intern/ghost/intern/GHOST_ContextGLX.cpp +++ b/intern/ghost/intern/GHOST_ContextGLX.cpp @@ -94,7 +94,7 @@ GHOST_ContextGLX::~GHOST_ContextGLX() if (m_context != None) { if (m_window != 0 && m_context == ::glXGetCurrentContext()) - ::glXMakeCurrent(m_display, m_window, NULL); + ::glXMakeCurrent(m_display, None, NULL); if (m_context != s_sharedContext || s_sharedCount == 1) { assert(s_sharedCount > 0); @@ -308,6 +308,8 @@ const bool GLXEW_ARB_create_context_robustness = GHOST_TSuccess success; if (m_context != NULL) { + const unsigned char *version; + if (!s_sharedContext) s_sharedContext = m_context; @@ -325,7 +327,16 @@ const bool GLXEW_ARB_create_context_robustness = /* re initialize to get the extensions properly */ initContextGLXEW(); - success = GHOST_kSuccess; + version = glGetString(GL_VERSION); + + if (version[0] < '2' || ((version[0] == '2') && (version[2] < '1'))) { + fprintf(stderr, "Error!
