Do you have the logs from the sperger build? I think the problem is that mplayer2 build system does CPU type autodetection. The failed build used -mcpu=v8, however if I run it on my machine (SunBlade 1000), I see that it compiles with -mcpu=ultrasparc. If compilation on sperger used -mcpu=ultrasparc as well, then it does not tell us anything, and it will fail again on buildds. It looks like -mcpu=ultrasparc should always be used, because we do not support earlier machines anymore. For example, our system binaries report: jurij@debian:~/mplayer/mplayer2-2.0-134-g84d8671$ file /bin/ls /bin/ls: ELF 32-bit MSB executable, SPARC32PLUS, V8+ Required, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.26, BuildID[sha1]=0xdef701c1cd7c87aa36fb4955a5cd430e9f2bd1d1, stripped which is what is produced when -mcpu=ultrasparc is used. With -mcpu=v8 one gets: jurij@debian:~/mplayer/mplayer2-2.0-134-g84d8671$ file mixer.o mixer.o: ELF 32-bit MSB relocatable, SPARC, version 1 (SYSV), not stripped I think the right way to fix it is to turn off (possibly broken) CPU type autodetection and always use -mcpu=ultrasparc.
