Anyone using uClibc on a 405GP platform?

Anyone using uClibc on a 405GP platform?

[Torben Mathiasen]

Hi,

Does anyone successfully use uClibc on a 405GP platform? I tried compiling
uClibc but all my dynamic apps just segfault. Its the shared library loader
that segfaults immediately after execve(). I tried both a recent 2.4 and 2.6
kernel with the same result. Also using latest 0.9.26 uClibc.

Has anyone gotten this to work?

On my i386 platform uClibc works very well.

Thanks,
Torben

ldso is broken in 0.9.26 uClibc for powerpc, try latest uClibc CVS.
There might be some problem with dlopen and friends in CVS still.

Funny, I got this to work. I was under the assumption that one should be able
to execute the library loader directly, which has never worked for me on
powerpc. But a dynamic linked application seems to be working now. Both those
I compiled myself and the ones I got from the root_fs_powerpc fs.

hmm, not sure about executing ldso directly, you may have better luck asking
about that on the uClibc list.

ldso is however somewhat broken. Lots of stuff/fixes has been added
since the last release.

Thanks for the info. The uClibc I'm using now is the latest from CVS.
