Trouble with dynamic executables

[Andrew Duane]

I'm assuming it's a change to "ld", but it could be one of the directive scripts. I spent yesterday combing changes to the tree, and looking for any files that could have caused this. I came up empty, but then I'm not really sure what I'm looking for. Is there a toolchain person who might know? There's a good person here at Juniper, but he's on California time....

I had a similar issue the other day when i did a fresh build world. I tried it to reproduce the issue you reported and its pretty much there in the trunk.
But the last buildworld has no such issues and am still using the same old fs image to boot on to the octeon boards.

I believe, some recent fixes should have caused this.

Thanks,
Bhanu Prakash.

I've pretty much completed my board bringup of an OCTEON based board, but am still battling one *major* issue. Dynamically linked executables do not work at all. Any time I try to run one, I get "Exec format error" (ENOEXEC). Sample output from file is:

Statically linked /bin/cat:

bin/cat:      ELF 64-bit MSB executable, MIPS, MIPS64 rel2 version 1 (FreeBSD), for FreeBSD 9.0 (900035), statically linked, FreeBSD-style, not stripped

Dynamically linked /usr/bin/size:

usr/bin/size: ELF 64-bit MSB executable, MIPS, MIPS64 rel2 version 1 (FreeBSD), for FreeBSD 9.0 (900035), dynamically linked (uses shared libs), FreeBSD-style, not stripped

For now, I've sort of worked around this by editing close to 1000 Makefiles and making almost everything static. There must be a reason for this though. I've done a fresh update and rebuilt everything including the toolchain. Is there something missing from my system? The loader itself? Libraries? An ldscript file?
