Hello all,
Ive been trying to compile openssh using buildroot, and just like
samba, it compiles fine but any executable halts with "segmentation
fault". Ive tried making buildroot with both gcc 4.2.0 and 3.4.6
(uclibc 0.9.29) - same results. I would appreciate if anyone can
please tell me how he had succeeded compiling (and executing...)
openssh successfully.
here is the strace output of ssh :
[root at zmob /]$ strace ssh --help
