Description Robert Wohlrab 2008-11-14 16:03:03 UTC
I checked the package for undefined reference and got undefined reference. For
testing purposes LDFLAGS in /etc/make.conf was changed to
 LDFLAGS="${LDFLAGS} -Wl,-z,-defs -Wl,--no-undefined"
The reported problem is in most cases a upstream problem - please report it
upstream if it is so. Please use the man page to find the needed library. For
example dlsym would need '-ldl' ( or cosf need '-lm' (

changing severity for easier searching.
Comment 2 Gilles Dartiguelongue gentoo-dev 2009-05-31 16:20:23 UTC
Do you have a link to a gentoo doc that would explain the problem with this ? It is easier to argue with upstream if there is such doc available.

Fixes the issue mentioned in #c1.
Comment 5 Romain Perier (RETIRED) gentoo-dev 2009-07-03 22:28:19 UTC
The entry about as-needed and no-undefined into diego's blog is very interesting and very clear.

Well patch seems to be mostly correct.
Comment 6 Pacho Ramos gentoo-dev 2010-03-22 17:24:28 UTC
Is this still an issue with dev-libs/libxml2-2.7.7 ?

Maybe we could try to use it in next bump if possible (since upstream looks to not care). What do you think?

Comment 9 Pacho Ramos gentoo-dev 2011-04-18 17:12:37 UTC
As talked with Gilles and Samuli on #gentoo-desktop, it builds fine with forced as-needed and gold linker, then, we will leave upstream to decide to fix this.
