I fired up qemu with debian from http://people.debian.org/~aurel32/qemu/arm/ (thanks, Dhirendra)... now it's not a segfault, it's illegal instruction:

gdb:
Starting program: /rooy/mpg123-arm-linux/mpg123-arm-noasm-quality --help

Program received signal SIGILL, Illegal instruction.
0x00008118 in start()


I ran qemu as the "versatile" machine (the command indicated on that web site, -M versatilepb), it outs itself as
Processor         : ARM926EJ-S rev 5 (v5l)
Features          : swp half thumb fastmult vfp edsp java
CPU architecture  : 5TEJ

So, Taihei's binaries seem not to be compatible with this config, at least (and probably it's the same on my eBook reader). But I compiled some mpg123 variants in the qemu vm (man, that took ages!) and am starting some testing now.
Maybe those will work on the real ARM in my eReader, too.


Alrighty then,

Thomas.
