Dear MPlayer users, I used to compile the CVS version of MPlayer regularly, but when I tried yesterday (interrested by divx5 support), it compiled but didn't run. It segfaults at start, with or without arguments. Following is some info about my environment, thanks for your kind help. Lucas Vergnettes. -- CVS from 20/3/2002 % ./mplayer zsh: segmentation fault ./mplayer I tried compilation with gcc 2.95.4 and gcc 3.0.4, with and without processor auto detection. I'm on debian unstable, kernel 2.4.18 jp6 (preempt + xfs) ### Long hardware/software report following : % cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 4 model name : AMD Athlon(tm) Processor stepping : 2 cpu MHz : 998.956 cache size : 256 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 mmx fxsr syscall mmxext 3dnowext 3dnow % uname -a Linux insomnia 2.4.18-jp6 #1 lun mar 4 11:43:14 CET 2002 i686 unknown % ls -l /lib/libc[.-]* -rwxr-xr-x 1 root root 1170812 fév 4 08:03 /lib/libc-2.2.5.so lrwxr-xr-x 1 root root 13 fév 5 17:37 /lib/libc.so.6 -> libc-2.2.5.so XFree86 Version 4.1.0.1 / X Window System GNU ld version 2.12.90.0.1 20020307 Debian/GNU Linux % gcc -v && gcc-3.0 -v Reading specs from /usr/lib/gcc-lib/i386-linux/2.95.4/specs gcc version 2.95.4 20011002 (Debian prerelease) Reading specs from /usr/lib/gcc-lib/i386-linux/3.0.4/specs gcc version 3.0.4 % as --version Assembleur GNU 2.12.90.0.1 20020307 Debian/GNU Linux ########## And the gdb trace : (gdb) run -v Starting program: /s/CompileFarm/Mplayer/main/./mplayer -v Program received signal SIGSEGV, Segmentation fault. 0x40008ee3 in ??
