Bugzilla Bug 196422

When LDFLAGS has been set to "-Wl,--as-needed", dev-libs/clearsilver is not
linked against zlib, even when zlib is in USE flags.

Attach the complete compile log here, as well as emerge --info output. Thanks.

So what's wrong then? Is there something that doesn't work when libz isn't
linked in?

Yup, for example trac doesn't work spewing out an error about undefined symbol
"deflate".

There is some discussion going on in the Clearsilver message board, including a
patch:
http://tech.groups.yahoo.com/group/ClearSilver/message/1074

This is the error what it causes:

Traceback (most recent call last):

Fixes the problem for me...


Any ideas whether 0.10.5 will be bumped and/or stabilized...

Well, trac works for me if clearsilver is compiled with -zlib, I don't get the
"no deflate symbol" error. Anyway, I added your patch to the clearsilver-0.10.5
ebuild I just commited. Please test and report, thanks.

Works fine on x86 (after keywording).
