我的系统是debian sid amd64, 显卡是geforce 9500 gt, 在上面用gtkglextmm做开发的时侯出现segmentation fault错误，有人说是显卡的驱动有错，要去装nvidia的原装驱动，有人说是mesa有错，不知道有没有人有经验？ 下面是错误信息： ==3503== ERROR SUMMARY: 3 errors from 2 contexts (suppressed: 275 from 5) ==3503== ==3503== 1 errors in context 1 of 2: ==3503== Conditional jump or move depends on uninitialised value(s) ==3503== at 0x5F8BF98: glXWaitGL (glxcmds.c:620) ==3503== by 0x5AD6730: _gdk_gl_context_destroy (gdkglcontext-x11.c:95) ==3503== by 0x5ABA8B1: gdk_gl_context_destroy (gdkglcontext.c:118) ==3503== by 0x5243BC1: gtk_gl_widget_unrealize (gtkglwidget.c:149) ==3503== by 0x9CB211C: g_closure_invoke (gclosure.c:767) ==3503== by 0x9CC5C2A: signal_emit_unlocked_R (gsignal.c:3247) ==3503== by 0x9CC7021: g_signal_emit_valist (gsignal.c:2980) ==3503== by 0x9CC74F2: g_signal_emit (gsignal.c:3037) ==3503== by 0x792ED61: gtk_widget_unrealize (in /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== by 0x7934ABC: gtk_widget_unparent (in /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== by 0x783C257: (within /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== by 0x9CB211C: g_closure_invoke (gclosure.c:767) ==3503== Uninitialised value was created by a heap allocation ==3503== at 0x4C2391E: malloc (vg_replace_malloc.c:207) ==3503== by 0x5FACEFD: driCreateScreen (drisw_glx.c:362) ==3503== by 0x5F8DDEE: __glXInitialize (glxext.c:622) ==3503== by 0x5F8918C: GetGLXPrivScreenConfig (glxcmds.c:183) ==3503== by 0x5F8A00E: glXChooseVisual (glxcmds.c:1304) ==3503== by 0x5AD60CB: gdk_gl_config_new_common (gdkglconfig-x11.c:519) ==3503== by 0x5ABA1EE: gdk_gl_config_new_rgb (gdkglconfig.c:193) ==3503== by 0x5ABA316: gdk_gl_config_new_by_mode_common (gdkglconfig.c:210) ==3503== by 0x503A75A: Gdk::GL::Config::create(Gdk::GL::ConfigMode) (in /usr/lib/libgdkglextmm-x11-1.2.so.0.0.0) ==3503== by 0x4149FB: SurfaceView::SurfaceView(bool) (SurfaceView.cc:81) ==3503== by 0x415171: MechanicalSystemUi::MechanicalSystemUi() (Ui.cc:19) ==3503== by 0x40E1D0: main (main.cc:66) ==3503== ==3503== 2 errors in context 2 of 2: ==3503== Conditional jump or move depends on uninitialised value(s) ==3503== at 0x5F8BE57: glXWaitX (glxcmds.c:659) ==3503== by 0x9CB211C: g_closure_invoke (gclosure.c:767) ==3503== by 0x9CC5C2A: signal_emit_unlocked_R (gsignal.c:3247) ==3503== by 0x9CC7021: g_signal_emit_valist (gsignal.c:2980) ==3503== by 0x9CC74F2: g_signal_emit (gsignal.c:3037) ==3503== by 0x792D269: gtk_widget_size_allocate (in /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== by 0x783F157: (within /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== by 0x9CB206E: g_closure_invoke (gclosure.c:767) ==3503== by 0x9CC5512: signal_emit_unlocked_R (gsignal.c:3177) ==3503== by 0x9CC7021: g_signal_emit_valist (gsignal.c:2980) ==3503== by 0x9CC74F2: g_signal_emit (gsignal.c:3037) ==3503== by 0x792D269: gtk_widget_size_allocate (in /usr/lib/libgtk-x11-2.0.so.0.1600.1) ==3503== Uninitialised value was created by a heap allocation ==3503== at 0x4C2391E: malloc (vg_replace_malloc.c:207) ==3503== by 0x5FACEFD: driCreateScreen (drisw_glx.c:362) ==3503== by 0x5F8DDEE: __glXInitialize (glxext.c:622) ==3503== by 0x5F8918C: GetGLXPrivScreenConfig (glxcmds.c:183) ==3503== by 0x5F8A00E: glXChooseVisual (glxcmds.c:1304) ==3503== by 0x5AD60CB: gdk_gl_config_new_common (gdkglconfig-x11.c:519) ==3503== by 0x5ABA1EE: gdk_gl_config_new_rgb (gdkglconfig.c:193) ==3503== by 0x5ABA316: gdk_gl_config_new_by_mode_common (gdkglconfig.c:210) ==3503== by 0x503A75A: Gdk::GL::Config::create(Gdk::GL::ConfigMode) (in /usr/lib/libgdkglextmm-x11-1.2.so.0.0.0) ==3503== by 0x4149FB: SurfaceView::SurfaceView(bool) (SurfaceView.cc:81) ==3503== by 0x415171: MechanicalSystemUi::MechanicalSystemUi() (Ui.cc:19) ==3503== by 0x40E1D0: main (main.cc:66)
