Good morning Kai,
I tried redirecting default-output as you suggested but unfortunately it
seemed to make no difference. The program still crashes with the same 'out
of memory' error in the xterm window and strace is still showing that it's
trying to allocate too much memory:
read(6,
"\241\10\252\tu\n\361\10\333\10V\10\204\5u\7\241\6%\5M\6"..., 4096) = 2934
_llseek(6, 0, [0], SEEK_SET) = 0
read(6, "RIFFn\213\0\0WAVEfmt \20\0\0\0\1\0\1\0D\254\0\0\210X\1"...,
4096) = 4096
_llseek(6, 4096, [4096], SEEK_SET) = 0
_llseek(6, 4096, [4096], SEEK_SET) = 0
_llseek(6, 4096, [4096], SEEK_SET) = 0
old_mmap(NULL, 268439552, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
brk(0x18127000) = 0x8126000
old_mmap(NULL, 2097152, PROT_NONE,
MAP_PRIVATE|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0) = 0x40c77000
munmap(0x40c77000, 561152) = 0
munmap(0x40e00000, 487424) = 0
mprotect(0x40d00000, 32768, PROT_READ|PROT_WRITE) = 0
old_mmap(NULL, 268439552, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
write(2, "out of memory", 13out of memory) = 13
write(2, "\n", 1
) = 1
_exit(1)
I don't know if the above is of any help, but I thought you may be able to
make some sense of it. I'm wondering if there is something fundamental that
I could be doing wrong. As I said already, I'm fairly new to Linux and Unix
so if you can think of any basic things that need checking, let me know -
although I did make an effort to follow the Install instructions to the
letter.
Thanks for the help,
Alex.
