MORIN. > Damn! it was that simple. chmod a+x /lib/ld* fix it. My hello.dyn and gnuplot now work. I posted quite some time back in another thread that all my libs were without x perms and it got no comment. So I assumed that it was normal and the it was regarded as a dumb question. So the question is: why is it installed with the wrong permissions? I have just rebuild the toolchain and the perms look correct in sys-root. 3317406 -r-xr-xr-x 1 prof users 160750 2009-06-10 01:49 ld-2.9.so 3317408 lrwxrwxrwx 1 prof users 9 2009-06-10 01:49 ld-linux.so.3 -> ld-2.9.so However ldd still does not work: # ldd gnuplot -sh: ldd: not found # which ldd /usr/bin/ldd I think what may have happened it that , having noted that nothing had x in /lib I added it to all libs without noting that ld was (possibly) already executable. When I did not get any comment on that I likely reverted everything including ld to -x . I'll do more thorough testing tonight but initial evidence suggests that it is fixed. It would be good to have ldd as a tool but I think that is a differenct problem. It tool a long time to find something so simple but at least I can rebuild everything dynamic now.
