Problems after having crosscompiled for XScale

[Rogier Stam]

Thanks for the reply. Unfortunately no LDD. But using arm-linux-objdump 
-x reveals the following:
Dynamic Section:
  NEEDED      libc.so.0
  NEEDED      libdl.so.0
  NEEDED      libz.so
  NEEDED      libcrypto.so.0.9.8
  NEEDED      libutil.so.0
  NEEDED      libcrypt.so.0
  NEEDED      libresolv.so.0
  HASH        0x8130
  STRTAB      0x9888
  SYMTAB      0x8858
  STRSZ       0xa56
  SYMENT      0x10
  DEBUG       0x0
  PLTGOT      0x4551c
  PLTRELSZ    0x758
  PLTREL      0x11
  JMPREL      0xa328
  REL         0xa2e0
  RELSZ       0x48
  RELENT      0x8

I cut out only the dynamic section ... I didnt think the rest was very 
relevant in this case. I made sure this time that the libz was there 
this time, and the binaries were compiled against this library. The 
library list:

As a further test I tried the following:
export 
LD_PRELOAD=/lib/libc.so.0:/lib/libdl.so.0:/lib/libz.so:/lib/libcrypto.so.0.9.8:/lib/libutil.so.0:/lib/libcrypt.so.0:/lib/libresolv.so.0
ssh

The result remains the same. Even adding some printf statements to the 
beginning of main in ssh.c did not show up. I'm beginning to wonder if 
something is linked wrong ?

I hope you can help....

Thanks so far & regards,
