Hi, I have compiled mesa with the following options:.././configure --prefix=~/lib/mesa/swrast/ --build=x86_64-linux-gnu --with-gallium-drivers= --with-driver=xlib --enable-egl --enable-gles1 --enable-gles2 --with-egl-platforms="x11" CFLAGS="-Wall -g -O2" CXXFLAGS="-Wall -g -O2" but when I run a sample app with the following egl config, it returns 0 configs. EGLint attr[] = { // some attributes to set up our egl-interface EGL_BUFFER_SIZE, 16, EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT, EGL_NONE }; EGLConfig ecfg; EGLint num_config; if ( !eglChooseConfig( egl_display, attr, &ecfg, 1, &num_config ) ) { cerr << "Failed to choose config (eglError: " << eglGetError() << ")" << endl; return 1; } The code above prints 'Failed to choose config'. While the same code works fine when I compile with: ../../configure --prefix=~/lib/mesa/dri --build=x86_64-linux-gnu --with-driver=dri --with-dri-drivers="swrast" --with-dri-driverdir=~/lib/mesa/dri/ --with-dri-searchpath='~/lib/mesa/dri' --enable-glx-tls --enable-xa --enable-driglx-direct --with-egl-platforms="x11" --enable-gallium-llvm=yes --with-gallium-drivers="swrast" --enable-gles1 --enable-gles2 --enable-gallium-egl --disable-glu CFLAGS="-Wall -g -O2" CXXFLAGS="-Wall -g -O2" Could someone please suggest what could be causing this?
I suspect that, in the first build configuration, the built EGL does not support 16-bit configs. Does your app work if you set EGL_BUFFER_SIZE=24 or EGL_BUFFER_SIZE=32? _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
