glibc-2.3.6-r5 fails to build on SGI O2 w/ mips-unknown-linu

iMike

Anyone having trouble building glibc on an O2? This is not a cross-compiler problem, cause I'm building directly on the O2. I recently switched to the new 2007.0 profile and am attempting to upgrade glibc from 2.3.6-r4 to 2.3.6-r5 (all under stable).

I get:

Hi,

if you use the parallel make feature you should post some more lines above the error message.

But not sure if it is the reason could also be that there is something missing on your system.

Did you also update the mips-headers package?

Which profile do you use exactly as I can select different USE flags for glibc on my machine.

On my Octane2 the next version of glibc also is

Hi,

I do use -j2 in make.conf, but had never considered any adverse implications of that before. I see how it could mean there is a problem with the build not shown simply in the above message. I put the whole emerge log file at http://www.pdc.kth.se/~mike/mips/ but nothing jumped out at me different that what was already stated. Also in the same spot is an emerge --info.

The sys-kernel/mips-headers and kernel I use are:

Hi,

finally the glibc build here after updating mips-sources to the newest stable version.

Setting the make to not parallel will just bring the error at the end of the log
I just asked for more text as a parallel make could print an error stopping one process
and then another screen full of information of another process and then finally exit.

To me it is clear that O2 and Octane2 are not the same
but if I understand http://www.linux-mips.org/wiki/ correctly
it could be possible to get compatible userspace code if
the least common CPU type is used ( same as with -mcpu=i686 for P2, P3, P4, Athlon and Opteron )
in this case r5k instead of r10k which is supported for Octane(2)
as the lower level differences should only need adressing from kernel side.

Maybe one of the MIPS xpert could clarify this.

Anyway I will try to find anything useable in your log but I would suggest to update mips-sources and mips-headers
first if they show up in the dependency graph of glibc as your original post shows.

regards

so, after some grepping:

there are a lot of ( 82 ) these:

gawk: ../scripts/versions.awk:90: (FILENAME=- FNR=1713) fatal error: internal error

So maybe first update gawk if some files are processed by gawk during the build.

Yes, there are a lot of gawk errors, but interestingly enough, they are all regarding the same file, namely

Hm,

no clue left on my side, maybe switch to ntpl-only
if you do no longer need the old linuxthreads?

Just checked my build, linuxthreads build also but there is no scripts directory.

If I get some time I will also try with the 2007 profile for IP30
just to rule out a bug in the profile.

OK, something strange is going on. I was going to try your suggestion by turning on nptl and nptlonly. First I just put this in my
/etc/portage/package.use file:

Unfortunately, changing back to the old 2006.1 profile does not help (nor does it give the possibility of set nptl or nptlonly). Perhaps glibc-2.3.6-r4, but not 2.3.6-r5 works on O2.

Hi again,

there is a nptl profile available in the tree:

Hi,

maybe this is good news?

Build successfully with profile

The profile that I'm using is:

As I am now trying the nptl profile you mentioned, I see that there has also been a version bump in glibc. Whereas my system was previously trying to build 2.3.6-r5 when I originally posted this problem, it now is picking up 2.3.6-r4. We'll see if the move from 2.5.r2 to r4 goes smoother than to r5.

I got a bit confused in the version numbering trying the switch to the ntpl profile. For the record, you get an upgrade to a completely different version, apparently, if you try ntpl:

I was quite able to upgrade my O2 (running fresh install of Gentoo/MIPS) to glibc-2.5...
