Hello, I follow MesaCVS quite closely, and I frequently build it for my linux-alpha machine. However, since a month or so, I can no longer run gl apps linked against mesacvs libs. build cmd: make linux-alpha-elf (I also tried autoconf) *ALL* apps crash with a segm violation, except for glinfo. They all crash in xform funcs. root@jerom:/usr/src/MesaCVS/demos# ldd gears libglut.so.3 => /usr/local/lib/libglut.so.3 (0x0000020000006000) libGLU.so.3 => /usr/local/lib/libGLU.so.3 (0x000002000015e000) libGL.so.3 => /usr/local/lib/libGL.so.3 (0x0000020000276000) libm.so.6.1 => /lib/libm.so.6.1 (0x00000200004e0000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x0000020000618000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x0000020000802000) libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x0000020000912000) libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x0000020000a2e000) libc.so.6.1 => /lib/libc.so.6.1 (0x0000020000b3a000) libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x0000020000d68000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x0000020000ed6000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x0000020001120000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000020001000000) Program received signal SIGSEGV, Segmentation fault. transform_points3_general_raw (to_vec=0x12011ede8, mat=0x12010d9e0, from_vec=0x120192f70, mask=0x0, flag=0 '\000') at xform_tmp.h:527 527 to[i][0] = m0 * ox + m4 * oy + m8 * oz + m12; (gdb) where #0 transform_points3_general_raw (to_vec=0x12011ede8, mat=0x12010d9e0, from_vec=0x120192f70, mask=0x0, flag=0 '\000') at xform_tmp.h:527 #1 0x2000045ad48 in do_vertex_pipeline (VB=0x12011ec80) at stages.c:333 #2 0x200004325d4 in gl_run_pipeline (VB=0x12011ec80) at pipeline.c:470 #3 0x2000049a7b4 in gl_execute_cassette (ctx=0x12010b2b0, IM=0x1201741d0) at vbxform.c:877 #4 0x200003f2cec in execute_list (ctx=0x12010b2b0, list=1) at dlist.c:2457 #5 0x200003f4468 in gl_CallList (ctx=0x12010b2b0, list=1) at dlist.c:3086 #6 0x200003be164 in glCallList (list=537975264) at api1.c:176 #7 0x120003a44 in draw () at gears.c:186 #8 0x200001432ec in processWindowWorkList (window=0x120107450) at glut_event.c:1273 #9 0x20000143428 in __glutProcessWindowWorkLists () at glut_event.c:1320 #10 0x200001434dc in glutMainLoop () at glut_event.c:1341 #11 0x1200045c4 in main (argc=1, argv=0x11ffffbb8) at gears.c:351 The problem is in to_vec (gdb) print* to_vec->data Cannot access memory at address 0x20120fc0. 2D apps like bounce, crash in transform_points2_3d_no_rot_raw, in another line of xform_tmp.h I don't think it is a 64bit long thing, because a lot of people run on Irix, and there have been no complaints. Anyone got an idea what it can be? Bram _______________________________________________ Mesa-dev maillist - [EMAIL PROTECTED] http://lists.mesa3d.org/mailman/listinfo/mesa-dev
