Bug 152654 – net-misc/quagga-0.99.5 does not emerge with --as-needed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Matthias Schwarzott 2006-10-24 06:30:28 UTC]

net-misc/quagga-0.99.5 does not emerge with LDFLAGS="-Wl,--as-needed" set.
Without --as-needed emerge works.

[Comment 1 Matthias Schwarzott 2006-10-24 06:53:16 UTC]

Created attachment 100380 [details, diff]
quagga-0.99.5-as-needed.diff

The attached patch makes quagga link with --as-needed.

The cause is that ../lib/.libs/libzebra.so uses functions of libcap but does not link against it. The patch fixes it.

[Comment 2 Alin Năstac (RETIRED) 2006-11-11 08:59:59 UTC]

Reassigned to me since now I'm the only quagga maintainer left.

[Comment 3 Alin Năstac (RETIRED) 2006-11-11 09:45:35 UTC]

Fixed in cvs, without revision bump, by merging your patch and zebra-linkorder.patch into link-libcap.patch.

As a side note, on my test machine zebra-linkorder.patch was enough to make quagga compilable with LDFLAGS=-Wl,--as-needed.

P.S. If you want to increase the chance of your bugs being fixed, add to CC all the maintainers. I thought you found another solution to your problem.

[Comment 4 Robert Buchholz (RETIRED) 2008-07-06 22:40:28 UTC]

This is still unfixed in our stable ebuild -- any chance the patch might be applied there?

[Comment 5 Alin Năstac (RETIRED) 2008-07-08 20:05:17 UTC]

I've added the patch to version 0.98.6-r4.
