Re: Need advise about linux32 on amd64

[Cem Kayali <cemkayali%eticaret.com.tr@localhost>]

Same software, on NetBSD i386 / 4.99.64, with suse100_base only and works without problem...

I copied ptrace section:

...

...
   575      1 linux_32_software RET   fork 700/0x2bc
   575      1 linux_32_software CALL  waitpid(0x2bc,0xbfbf6a7c,0)

   700      1 linux_32_software CALL  gettimeofday(0xbfbf37c0,0xbfbf37c8)

about a hundreth lines continue... If i can not run this software, i think i need to install amd64 and i386 onto different partitions. Or if you have advise, i appreciate.

Thanks.

Well, 'ktrace -i' produces same messages but additional ones too:

Specifically, it is ptrace problem i think...

Regards,
    

ptrace is not implemented on linux32; Does it work on i386? Can
you ktrace it [just after the fork where it calls ptrace]? I find
it strange that it works on i386 because ptrace just returns ENOSYS
currently.
