I've been working on trying to get an e500v2 (linux-gnuspe) compiler working and seem to have build a native toolchain. However when I try and compile a simple hello world style app I get:

root@p2020-ds:~# gcc float.c
gcc: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found
compilation terminated.

Wondering if anyone's seen this before and had any ideas.

You can try -fno-use-linker-plugin as a workaround. Does
liblto_plugin.so exist on target rfs ?
it might be then gcc driver bug if the library is not there then we
forgot to package it.

File appears to be there:

So not clear why its not finding it.

This looks similar to Yocto Bug 1233 (http://bugzilla.yoctoproject.org/show_bug.cgi?id=1233

Can you confirm if you have the following commit in your branch?
http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=2429773613cb95b6a0541b5cce6ce1338d5cfc2b

It's possible you might be missing this and it's not finding the file correctly.

As Richard mentioned also, an strace output would be helpful if you do have the above commit.

Thanks
Sau!
