Invalid ELF header?
« on: August 12, 2010, 06:01:23 AM »
Just built an extension which has several executables in /usr/local/bin. These are working fine in the development environment. On a clean TC 3.0 few of them do not start (no any message). Executing ldd on them I get 'Invalid ELF header' message. Other executables are OK after loading dependencies. ldd works es expected on them.

It is strange. Also, doesn't help to identify missing deps. :(

PM me the problematic ones.
The only barriers that can stop you are the ones you create yourself.

Perhaps the output of running
Code: [Select]
file on them (and compare with working executables) could give any clue?

Both are bash scripts.

Usually when a script interpreter is missing, you get an error "file or directory not found" - this threw me off. :)

Shit... I'm really stupid. This is the result if one is doing many thing in parallel, like me at the moment without concentrating on trhe problem  ;D Sorry for that. Hope you were laughing a lot at least which is healthy. I broke my own rules also, post such issues on a forum at least 24 hours later. As a week excuse I'm hunting for a dirty little thing running on my CentOS server hacking SSH port of Columbia University servers :(

And sorry again
