You don't want to disable built-in OpenGL when building with Regal, because Regal will tack on top of OpenGL ES 2.0. But you should build code without -s LEGACY_GL_EMULATION=1 linker flag, because when using Regal, Emscripten provided legacy GL emulation features are not needed. It could be the case that Regal needs more complete GLES2 options, in which case try building with -s FULL_ES2=1.
Try checking the link order of the -l items for Regal (or try using a link group). The order of the link items matters on command line, and this looks like perhaps they were specified in the wrong order. It is possible to specify items multiple times, so you can try duplicating the link files twice, i.e. try passing -lyourcode -lRegalGLUT -lRegallib -lyourcode -lRegalGLUT -lRegallib. 2017-01-25 17:46 GMT+02:00 caiiiycuk <caiiiy...@gmail.com>: > * I can`t understand how I can disable built in opengl support. > > -- > You received this message because you are subscribed to the Google Groups > "emscripten-discuss" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to emscripten-discuss+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "emscripten-discuss" group.
