Description Ian Kumlien 2007-10-18 09:13:30 UTC

libtorrent fails to compile, the compiler recomends the user to try again with -fPIC. This error is due to gcc 4.2.2's new and inproved inlining herustics which means that it, in this case, inlines more code. But if we inline more code then the jumps gets larger.

(This might be AMD64 specific)

to fix, add:
    filter-flags -fpic
    append-flags -fPIC

In the right section of the ebuild.

Reproducible: Always

That's hardly something to be called fix. Reopen with actual errors and emerge --info please.

Comment 2 Ian Kumlien 2007-10-18 12:11:24 UTC

After i upgraded to 4.2.2 it REFUSED TO BUILD, i *had* to add those two lines. I can't reproduce atm and i don't know why, unless portage does something magical.
