#806 checkrefnumbering from test suite fails to link with g++-4.5

I don't think that gcc-4.5 is officially supported for the 2.0 release. And if I'm not mistaken, the program is gone in the trunk.

So, is this really a bug?

I didn't mean this bug report as a complaint. It could be a chance to solve issues with a compiler that's just around the corner before people who, contrary to me, actually try to get stuff done with dune. Personally, I'm just toying around and sharing oddities that I come across.

Could you please try if the problem persists with -fno-strict-aliasing?

(after rebuilding dune-grid with CXX=g++-4.5 and CXXFLAGS=-fno-strict-aliasing):

I'm sorry, but considering a linker error to be related to strict aliasing was absolut nonsens. It's really to hot here.

Cound you try which symbols are in the object files and if you have enabled the old numbering:

nm -C dune/grid/common/referenceelements.o |grep general nm -C dune/grid/.libs/libgrid.a |grep general grep DUNE_ENABLE_OLD_NUMBERING config.h

As dune-2.0.x will be the official realease for quite a while and linux distributions with gcc-4.5 as standard compiler will appear soon (e.g. OpenSUSE 11.3 in July) ignoring gcc-4.5 is IMHO not a good idea. If there are known problems we should try to fix them in 2.0.x.

In that case I suggest to setup automatic testing using gcc-4.5 (so that we know where the problems are). Moreover, this is an entirely different suggestion from this bug report.

It's just the explanaition why this should be considered a bug. Setting up the autobuilds is indeed a different issue.

I'm sorry, but considering a linker error to be related to strict aliasing was absolut nonsens. It's really to hot here.

I'm happy to hear that -- I was trying to make sense of it and really couldn't :)

I just gave it a shot (using svn version of the release). After disabling alberta (whose lib does not compile for gcc-4.5), it compiled and linked out of the box. Can you help reproducing the error?

A very incomplete list of questions could be:

Do I need the tarball or does it happen in the svn version, too?
Does it happen in 2.0.1, too?
Does it happen for other compilers (e.g., gcc-4.4 or gcc-4.3)?
Are the compiler flags important (i.e., does it happen without optimization)?

And of course, you should answer the obvious questions (maybe I just missed the ansers):

What is your linux distribution?
What is the architecture (i.e., i386 or amd64)?
How did you obtain this compiler (i.e., package or compiled by hand)?
What do you configure DUNE with?

Maybe someone else could also try to reproduce this "bug"?

What's 2.0.1? I can't find such a tarball at

http://www.dune-project.org/download/

It doesn't happen with gcc 4.4. It does happen with just CXX=-fno-strict-aliasing and thus no optimization as seen above.

I'm on exherbo linux, amd64, gcc-4.5 is one of my system-provided compilers, I just ran dunecontrol all; dunecontrol make check

I meant CXXFLAGS=-fno-strict-aliasing of course.

There is no dune/grid/common/test/checkrefnumbering.cc in the trunk of dune-grid.

Since the stuff is in the lib we can try to reduce the testcase. Could you try if the attached example compiles in dune-grid with one of the following:

g++-4.5 -std=c++0x -O2 -I../dune-common -I. linktest.cc dune/grid/.libs/libgrid.a g++-4.5 -std=c++0x -O2 -I../dune-common -I. linktest.cc dune/grid/common/referenceelements.o

BTW: 2.0.1 is the branch for the next bugfix release. You can get the core modules from

https://svn.dune-project.org/svn/dune-xxx/releases/2.0.1.

linktest.cc

That site requires authentication.

That's strange. One possible reason for failed linking if the symbol is defined is a wrong linking order. Although the order should be correct you could try to reverse it:

g++-4.5 -std=c++0x -O2 -I../dune-common -I. -c linktest.cc g++-4.5 -v dune/grid/.libs/libgrid.a linktest.o

You can also allow an arbitrary order. To this end use the collect2 command printed by the last command and enclose the above lib and object file with --start-group and --end-group.

You could also check if the object file in the lib is the same as the raw one:

ar p dune/grid/.libs/libgrid.a referenceelements.o | diff - dune/grid/common/referenceelements.o

g++-4.5 -v dune/grid/.libs/libgrid.a linktest.o

For completeness we should also try the arbitrary order approach replacing collect2 by your linker e.g. ld.

However if the symbol is there but linking fails this seems to be a linker problem. Especially if the object file in the archive links separately.

Perhaps you should file this as bug in your distributions binutils with libgrid.a and linktest.o attached.

Btw: Do you use standard binutils or gold? The later is known to fail linking sometimes.

I use gold. I just switched to the old ld and it didn't help, though. (I had it relink libgrid.a, too)

Did you also relink dune/grid/common/.libs/libgridcommon.a? You could try to link against this one directly.

I rebuilt everything, so yes.

Please try to link against libgridcommon.a in order to reduce the testcase.

I've just decided to bombard you with data, so here we go...

there don't appear to be any important differences between the respective config.log files

OK, let's try a custom 'lib'

ar q l.a dune/grid/common/referenceelements.o g++-4.5 linktest.o l.a

and

ar q l.a dune/grid/common/referenceelements.o g++-4.5 linktest.o l.a

those two instructions look identical... did you mean this?

The output of nm(1) shows that some symbols are V-weak with g++ 4.4 and W-weak with ++ 4.5... so I guess that's where the error is coming from.

nevermind that last comment of mine.

The second variant was meant to be 'ar qs ...' which should add a symbole table. However it seems to be there even without the 's' (see nm l-4.5.a)

Please try the following to see if the lib is processed:

g++-4.5 -t linktest.o l-4.5.a

Regarding the weak symbols: As far as I can see the symbols are 'unique' with g++-4.5 and V-weak with g++4.4. Following 'man nm' the 'unique' flag is a GNU extension to elf. Could it be possible that your linker doesn't recognize this correctly?

If we want to trace the symbol we can first obtain the real name with

g++-4.5 linkertest.o l-4.5.a -Xlinker --no-demangle

Then you can trace it with

g++-4.5 linkertest.o l-4.5.a -Xlinker --trace-symbol=[symbolname] -Xlinker --no-demangle

Indeed they are. Since it doesn't work with ld(1) either, I doubt it's the linker's fault, though (I'm on binutils 2.20.1-r2)

Rebuilding with CXXFLAGS='-g -O0 -fno-weak' makes it work for me.

You can try to force including all symbols of the lib:

g++-4.5 -Xlinker --whole-archive l-4.5.a -Xlinker --no-whole-archive linktest.o

That works, yes

So this works, too:

pipping@bogus ~/Downloads/dune-grid-2.0/dune/grid/common/test $ g++-4.5 -std=c++0x -g -O2 -fno-weak -o checkrefnumbering checkrefnumbering.o -Xlinker --whole-archive ../../../../dune/grid/.libs/libgrid.a -Xlinker --no-whole-archive -L/usr/lib64 -ldunecommon -lm

As far as I understand the linker will include all symbols from object files and only those that are used from archives. With the above option it will include all of them.

The question is why it does not recognize and use the symbol in the archive automatically. Perhaps this is related to the different way gcc-4.5 uses weak symbols in combination with our singleton-implementation.

What's the symbol type of '...::general' in linktest.o?

U.

Btw: You should change (simplex,3) to (simplex,1) in the example.

Comment	After some more tests Elias and I did this is perhaps an issue with the linker or object file generation in exherbo.

#806 checkrefnumbering from test suite fails to link with g++-4.5
