Link to gcc 4.7 bug. Which version of qt-webkit? Can we please have an emerge --info or a build.log or something? I can confirm the issue with qt-webkit-4.8.1, and the following emerge --info: IIRC the final ld call fails due to -fuse-ld=gold. removing that argument (3 times) allows completing the build.

zipped build log
full build log
please note, that i completed the build with ebuild <pkg> compile install qmerge, so there is some additional cruft therein.
log taken from /var/log/portage.
the error itself can be found before line 7316.
@toolchain It looks like gcc-4.7 no longer recognizes -fuse-ld=gold command line option. Is that expected? The list of changes at http://gcc.gnu.org/gcc-4.7/changes.html does not mention it and it doesn't seem the deprecation and subsequent removal of that option has ever been announced. err, i don't think any gcc version has accepted -fuse-ld=xxx (even though i really wish they'd merge the patches already). any package requiring that flag is broken. (In reply to comment #7) > err, i don't think any gcc version has accepted -fuse-ld=xxx (even though i > really wish they'd merge the patches already). any package requiring that > flag is broken. Well, that flag is accepted by gcc 4.5 and 4.6 at least and has been working fine until now. Anyway, what's the suggested replacement? Prior to 4.7 the gcc frontend would ignore any -f option sit didn't recognise; now it complains about them. There was a thread on either gcc@ or gcc-help@ complaining about the change. (In reply to comment #8) i really don't think that flag has ever been in any gcc release. the replacement is to not use the flag -- it's never been supported. (In reply to comment #9) that's not what i see: $ for v in 4.0.4 4.1.2 4.2.4 4.3.6 4.4.7 4.5.3 4.6.2 4.7.0 ; do \ gcc-$v -fuse-ld=gold test.c -c ; done cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option "-fuse-ld=gold" cc1: error: unrecognized command line option ‘-fuse-ld=gold’ gcc-4.7.0: error: unrecognized command line option '-fuse-ld=gold' Only Debian/Ubuntu GCC accepts that flag, and upstream has rejected it a couple times. So not a toolchain issue. The reason this doesn't fail for previous versions is the flag is being passed as a linker option. See the first entry in http://gcc.gnu.org/gcc-4.7/porting_to.html (In reply to comment #12) i don't that wording is quite right. previous versions would not barf if it was only passed when linking. $ gcc -c test.c $ gcc-4.4.7 -fuse-ld=gold test.o -o a.out <no error> so yes, gcc-4.7 has changed behavior, but any package using -fuse-ld=gold has always been wrong. fix your pkg :p. Ok guys, thanks a lot for the info! This is definitely a qt-webkit issue. And now fixed in CVS. Thank you all :) |
