Bug 247206 – x11-libs/cairo with USE="glitz" causes problems with forced --as-needed

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Hanno Böck 2008-11-17 14:14:12 UTC]

Building cairo with glitz support causes pretty much all apps that link against cairo to fail with forced as-needed.

Example gtk+:

This is still a problem of cairo, libcairo should link against libglitz I guess.

[Comment 2 Doug Goldstein (RETIRED) 2008-11-17 15:57:06 UTC]

ldd /usr/lib/libcairo.so
<snip>
	libglitz-glx.so.1 => /usr/lib/libglitz-glx.so.1 (0x00007f5fd348b000)
<snip>
	libglitz.so.1 => /usr/lib/libglitz.so.1 (0x00007f5fd1ce7000)
<snip>

It does and I build my system with as-needed..

LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common -Wl,--hash-style=gnu"

[Comment 3 Doug Goldstein (RETIRED) 2008-11-17 16:06:35 UTC]

$ scanelf -n /usr/lib64/libcairo.so
 TYPE   NEEDED FILE 
ET_DYN libpixman-1.so.0,libfreetype.so.6,libfontconfig.so.1,libglitz-glx.so.1,libpng12.so.0,libxcb-render-util.so.0,libxcb-render.so.0,libxcb.so.1,libXrender.so.1,libX11.so.6,libz.so.1,libm.so.6,libc.so.6 /usr/lib64/libcairo.so

libglitz-glx.so is the Glitz implementation we use on Linux and it's in there for me.

[Comment 4 Hanno Böck 2008-11-17 16:45:18 UTC]

cardoe, this is with a system with forced as-needed in the gcc profile, see:

[Comment 5 Peter Alfredsen (RETIRED) 2008-11-29 00:31:46 UTC]

Runnning eautoreconf on an ~amd64 system solves this, FWIW.

[Comment 6 Christoph Mende (RETIRED) 2008-12-07 14:14:48 UTC]

this is also on a system with forced as-needed:
angelos@odin ~ % scanelf -n /usr/lib64/libcairo.so
 TYPE   NEEDED FILE 
ET_DYN libpixman-1.so.0,libfreetype.so.6,libfontconfig.so.1,libpng12.so.0,libXrender.so.1,libX11.so.6,libz.so.1,libm.so.6,libc.so.6 /usr/lib64/libcairo.so 
angelos@odin ~ % ldd /usr/lib/libcairo.so|grep glitz
angelos@odin ~ % 
no glitz in there, same result as comment #0

[Comment 7 Christoph Mende (RETIRED) 2008-12-08 00:35:00 UTC]

also solved by removing export glitz_LIBS=-lglitz-glx from the ebuild (line 71, cairo-1.8.4)

[Comment 8 Doug Goldstein (RETIRED) 2008-12-08 22:41:28 UTC]

That was added when James Cloos, who's involved in upstream filed bug #166343. I'd have to evaluate the impact of removal.

(In reply to comment #8)

Just change it to:
glitz_LIBS="$(pkg-config --libs glitz-glx)"
The only thing glitz_LIBS contains is, AFAICT, the output of
pkg-config --libs glitz
but that's a subset of the above.

[Comment 10 Doug Goldstein (RETIRED) 2008-12-30 16:01:18 UTC]

This is fixed with cairo 1.8.6
