The actual date of the last emerge is not a year older, but around september/2010, which is nevertheless a lot of time anyway. :) Please give me some time while I prepare the logs to attach to the bug report. Created attachment 269237 [details]
config-fixincludes.log
This is the log which shows errors from the fixincludes directory.
Created attachment 269239 [details]
config-libmudflap.log
This is the output of configure in the libmudflap directory.

Emerge's build log.
Please ignore messages showing errors on PWD. I just run emerge when I was still into the directory where the temporary files were. This did not change the error message from the several times I compiled (most of them I moved out of the /var/tmp/portage directory).

emerge --info output
Created attachment 269245 [details]
emerge -pqv output
This completes the battery of attachments upload. Please let me know if there's something else useful that could be sent. that libgomp.so is supposed to be linked against librt.so itself. your configure output is showing things go wrong earlier: checking for clock_gettime... yes that should of course say: checking for clock_gettime... no checking for clock_gettime in -lrt... yes so attach the config.log from the libgomp subdirs I was able to compile (using -aB in order for it not to enter the system if successfull but yet compile everything) if I specified: USE="-mudflap -nls -nptl -openmp" emerge -aB gcc It still points towards libgomp not being linked against -lrt. What I don't understand now is why gcc-4.5.2 is not masked for me if it was supposed to be masked and I did not explicitly unmask it. I have no package.keywords not package.accept_keywords. My previous gcc version was 4.4.3 as of september 2010. Created attachment 269475 [details]
config-libgomp.log
I noticed here, the answer for 'looking for config_gettime' results to 'yes' as well.

Ah! By the way, I have already tried: LDFLAGS=-lrt emerge sys-devel/gcc It seems LDFLAGS is simply ignored as the same error ocurred. Anyway if that worked, I would expect larger binaries uselessly (is --as-needed still a default?) Created attachment 269481 [details]
Here's the make.conf from the box I am working on this issue.
Please note: Although there are these ricer flags on CFLAGS/CXXFLAGS, I have already tried with them (both at the same time) commented out, tried also MAKE_OPTS as -j3, j2 and j1.
It seems, if I disable openmp (USE=-openmp) the whole thing works out. I will confirm that information in a while.
you're using ~x86, so installing gcc-4.5.2 shouldnt be a surprise. try running the command in question: $ echo 'main(){return clock_gettime();}' > conftest.c $ gcc -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ \ -isystem /usr/i686-pc-linux-gnu/include \ -isystem /usr/i686-pc-linux-gnu/sys-include \ -o conftest -g -march=native -pipe -DSQLITE_HAVE_ISNAN -O2 -pthread conftest.c if that passes, add the flags "-v -Wl,--verbose -Wl,-M" and post the full output as an attachment Created attachment 269667 [details]
conftest.c with lotsa verbose options' output
Here is the output of the command:
gcc -B/usr/i686-pc-linux-gnu/bin/ -B/usr/i686-pc-linux-gnu/lib/ -isystem /usr/i686-pc-linux-gnu/include -isystem /usr/i686-pc-linux-gnu/sys-include -o conftest -g -march=native -pipe -DSQLITE_HAVE_ISNAN -O2 -pthread conftest.c -v -Wl,--verbose -Wl,-M
Just a heads up: I was able to compile the other directories once I moved directly to them and compiled. Of course, during emerge phase, the compiler used is the half-done gcc-4.5.2. As in the sandbox (emerge FEATURE), I expect the environment not to be the same as when I just run the plain command using my 4.4.3 already working compiler.
With 'other directories' I mean the failed fixincludes and libmudflap. Analysing the configure scripts, I noticed I always use gcc 4.4.3 when I run commands from commandline; when emerge does the configures, it really finds the 4.5.2 compiler.
The detailed comments of this 'heads up' are in the first comment, at the point where I start with 'As a dummy attempt'.
Should it be useful for anything: $ ./conftest; echo $? 255 $ your glibc looks like it is screwed up: libgomp.so.1 needed by /lib/libpthread.so.0 found libgomp.so.1 at /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libgomp.so.1 librt.so.1 needed by /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libgomp.so.1 found librt.so.1 at /lib/librt.so.1 libpthread.so should *not* be linked against libgomp.so. that make.conf you posted is not even close to the `emerge --info` you posted originally. what is going on ? did you run it on the wrong machine, or are you purposefully hiding info from us ? further, that LDFLAGS=-lgomp is simply stupid. you screwed up your system thus you get to fix it. please dont waste our time with this kind of crap. Of course I did not do that 'emerge --info vs make.conf' in purpose. As I said several times, I've changed lotsa options in order to try and find some combination that could work with that. When I took emerge --info I really had the lines CFLAGS commented out, thus the different output. In order to clear that out, I have this combo command, which shows you the same machine in the emerge --info with the options updated: ---- paste start ---- # cat /etc/make.conf ; emerge --info # These settings were set by the catalyst build script that automatically # built this stage. # Please consult /usr/share/portage/config/make.conf.example for a more # detailed example.

you could use better words, other than 'crap', or 'waste our time', 'screwed your system'. I am not testing you nor no one of the other people who voluntarily help maintain gentoo. I didn't.. I don't know what I have done to screw the system up. I mean to find it out but still I thought I could get some directions from the people around gentoo bugzilla. Despite all your pity tongue and inappropriate words, you gave me some directions, for what I am thankful. I just hope one day you rethink your ways on judging other people, or at least does not assume they are against you at sight. Last, I wish someone else attended to this request so I did not have to read such rude arguments. It seems the problem was resolved. I'm not sure if all this was really needed but the steps were: - remove -lgomp from LDFLAGS in make.conf emerge glibc emerge --oneshot libtool emerge gcc Then voila, it worked like a charm. |
