[Description malcolm.mielle 2017-11-13 23:25:43 UTC]

Can't compile kde-frameworks/khtml-5.40.0 on the ~amd64 branch. I tried to run a emerge -avDuN @world and got this:

[Comment 8 VELOCiTY 2017-11-15 14:21:43 UTC]

This error does not occur when using gcc 6.4.0

[Comment 9 Andreas Sturmlechner 2017-11-15 18:07:57 UTC]

Did you rebuild giflib after switching to GCC-5?

[Comment 10 malcolm.mielle 2017-11-16 11:15:25 UTC]

I don't know, I just ran "emerge --avDuN @world"

[Comment 11 Andreas Sturmlechner 2017-11-16 11:16:10 UTC]

If that's what you did after switching to GCC-5, that is not enough.

[Comment 12 malcolm.mielle 2017-11-16 11:19:08 UTC]

Well I'm not even sure when I switched to a new version of gcc. Sorry I'm pretty new to all this. What else would I need to do ?

Read the instructions in the following news item:

https://www.gentoo.org/support/news-items/2015-10-22-gcc-5-new-c++11-abi.html

[Comment 14 Samuel Panicucci 2017-11-16 16:57:05 UTC]

Similar error happends to me upgrading khtml. But as suggested switching to gcc 6 compile work fine.

[Comment 16 Michael Palimaka (kensington) 2017-11-19 06:59:47 UTC]

I wonder if this is related to newer glibc.

[Comment 17 Jochen Schlick 2017-12-11 21:30:40 UTC]

- have now exactly the same issue with khtml-5.41.0, gcc-5.4.0-r3, glibc-2.26-r3
- had no problems to build khtml-5.40.0 when it came out, but this was before the glibc update

[Comment 18 Ben Kohler 2017-12-13 21:29:28 UTC]

Is anyone able to reproduce this issue with gcc-6?

[Comment 19 Martin von Gagern 2017-12-18 11:59:02 UTC]

# objdump -T /usr/lib64/libgif.so.7.0.0 | grep reallocarray
… g    DF .text  000000000000004e  Base        reallocarray
# objdump -T /lib64/libc.so.6 | grep reallocarray
… g    DF .text  0000000000000062  GLIBC_PRIVATE __libc_reallocarray
…  w   DF .text  0000000000000062  GLIBC_2.26  reallocarray

So it would seem that giflib and and glibc actually export that symbol. The "w" in libc might denote a weak symbol, in which case the giflib version would take precedence. Is this indeed intended behavior, or would we prefer giflib built against more recent libc to neither declare nor export that symbol itself?

[Comment 20 Ben Kohler 2017-12-18 21:55:58 UTC]

FWIW I've been involved in helping troubleshoot 3 or 4 more of these on IRC, and in every case the user was on ~amd64 glibc-2.26, ~amd64 khtml-5.41.0, and older-than-current-stable gcc-5.4.0.

Bumping up to gcc-6 or higher has fixed all of them I've come across.

[Comment 21 Martin von Gagern 2017-12-18 22:26:56 UTC]

Do we have any understanding WHY newer GCC does not fail here? To me, GCC 5 looks correct: two conflicting symbols with two separate declarations, which happen to differ in their throws specification. I guess GCC feels more confident about that throws, but does that mean that using the implementations interchangably is safe?

[Comment 22 Andreas Sturmlechner 2017-12-28 12:16:10 UTC]

Everything pre-GCC-5.4 was masked, so there's nothing left to do here anymore.

[Comment 31 Sebastian Pipping 2018-03-14 18:08:04 UTC]

Hi!

giflib is at fault here.  Upstream commit https://sourceforge.net/p/giflib/code/ci/79946c0cf620c5360abc3b6bef1a86fb76112d60/ introduced the lines

  extern void *
  reallocarray(void *optr, size_t nmemb, size_t size);

to /usr/include/gif_lib.h.  Git history says that 5.1.2 was the first version of gitlib with these lines.

vapier has reported concerns about these lines independently, already.  No reaction upstream, yet.

Right now I think the best way to fix the issue would be to rename all uses, exports and the implementation of reallocarray in giflib (file openbsd-reallocarray.c) to "openbsd_reallocarray" in a new ebuild 5.1.4-r1.

What do you think?
