Bug#529091: openscenegraph: fails to build on armel "hidden symbol (...) is referenced by DSO"
Hi Guys, Good to see that this issue has been resolved. I write now to pass the info that I will probably be making a 2.8.2 quite soon as they have been a couple of regressions spotted in 2.8.1 that we due to bug fixes fixing some problems but introducing new ones when the code. Sigh... two steps forward, two steps back. If there is something that would be appropriate to roll into 2.8.2 to help out the armel build then let me know. Robert.

Bug#529091: openscenegraph: fails to build on armel "hidden symbol (...) is referenced by DSO"
Hello, I have found a solution. There was no help on the CMake side, as I wrote some days ago, as you can only operate on the linking flags, but not append new libraries to the proccess. So I went the linker route and found the "--whole-archive" option, that forces the linker to add all the object files of a library no matter if they are still not required. Then, the extra special definitions we have to pass CMake are: -D CMAKE_SHARED_LINKER_FLAGS="-Wl,--whole-archive -lgcc -lgcc_s -Wl,--no-whole-archive" and -D CMAKE_MODULE_LINKER_FLAGS="-Wl,--whole-archive -lgcc -lgcc_s -Wl,--no-whole-archive" The first one will add those libraries in the OSG linking libraries phase and the second will do the same in the plugins linking phase. The -lgcc parameter goes before the -lgcc_s, as shown. With this options, the compilation went fine until the end. Only several warnings of dh_shlibdeps about undefined symbols of the C standard library, triggered I suppose because we were linking to the whole gcc library with the whole-archive option. I executed osgversion with success. osgconv failed because the intrinsic undefined symbols in a plugin, but that was only because I forgot to add the CMAKE_MODULE_LINKER_FLAGS, so the plugins didn't receive their "-lgcc -lgcc_s" at linking stage. Since every compilation of the package spends 30 hours, I'm not going to test it inmediately, but I'm pretty sure that my solution is valid.

Unfortunately CMake puts the value of CMAKE_CXX_FLAGS at the beggining of the command line, so the symbols are still left undefined. The same goes for CMAKE_SHARED_LINKER_FLAGS. I was looking for something like CMAKE_LIBS, but I haven't found anything yet. I really think that should be possible without modifying CMakeLists.txt.

He says that it's basically a known bug that he has forwarded to gcc upstream, and in the meanwhile we can fix it on armel and hppa adding "-lgcc_s -lgcc" libraries. Hi, How did you add these two libraries ? I'll do the same and move on with 2.8.1 packaging.

I don't know of a current cmake way to disable the automatic selection of the atomic reference counting implemention, the present code is a series of tests that our CMakeModules/CheckAtomicOps.cmake file which is run by src/OpenThreads/CMakeLists.txt to determine the settings that are recorded in the include/OpenThreads/Config file. We could possible modify the relevant cmake to allow on to enable/disable to automatic detection, or to override it's result, but this would obviously take us away from a vanilla OSG-2.8.1 release. Perhaps if we can get CMake changes in place for OSG svn/trunk that work then we could back port these for the debian usage. I presume this is an issue with OSG-2.8.0, and perhaps even OSG-2.6.x as well. The other possibility and a bit of hack might be to provide a custom include/OpenThreads/Config file that overrides the automatically generated one.

Thanks :) Indeed I had written a modification of the CMakeLists.txt file in order to manually disable those operations, but this morning, gcc Debian maintainer Matthias Klose replied to the bug that I posted yesterday ( http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=530388). He says that it's basically a known bug that he has forwarded to gcc upstream, and in the meanwhile we can fix it on armel and hppa adding "-lgcc_s -lgcc" libraries. I made sure that adding those two libraries, my test example worked, so I think we can have atomic operations as well on armel. I'm now thinking how could we add those libraries for armel without modifying the CMakeLists.txt files, since it seems that is not as easy as with the Autotools where you can set the LIBS variable. I'm happy because today sparc compilation was also succesful (https://buildd.debian.org/pkg.cgi?pkg=openscenegraph), so this is the last step for having a new version of OSG in Debian :) Regards, Alberto -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".

Yes, I'm following now Peter's suggestion, so I have now a "qemulated"
armel system on my computer, and now I'm building the package on this
platform. If I'm successful reproducing the error, I can ping the OSG list
for a fix or at least for a switch in the CMake system in order to
deactivate that feature, in the case it were the culprit. The downside is
that the compilation is very slow, but at least I don't have to wait
several weeks and in additon, I can make as many tests as I need.
I have located the problem. Unfortunately it lies on Sid g++ versions 4.3.3-10
and 4.4.0-5 of armel's g++.
* Antecedents:
Newer versions of OSG make use of GCC builtin atomic operations where
available in order to improve efficiency (__sync_bool_compare_and_swap,
__sync_sub_and_fetch, __sync_add_and_fetch...). The specific code that uses
those GCC intrinsic functions is located in OpenThreads, but inlined on the
headers this library.
* Problem:
On armel, if one links an object file using those intrinsic functions to make
a shared object with the g++ driver, the intrinsic functions remain undefined
on the resultant library, that's why the build of OSG package fails when
linking the first executable, osgviewer. I have written this small testcase:
debian-armel:~# cat foo.c
void doit(void **p, void *val, void *val2)
{
__sync_bool_compare_and_swap(p, val, val2);
}
debian-armel:~# gcc foo.c -c
debian-armel:~# g++ -shared foo.o -o libfoo.so
debian-armel:~# nm -D libfoo.so | grep sync
U __sync_bool_compare_and_swap_4
debian-armel:~# gcc -shared foo.o -o libfoo.so
debian-armel:~# nm -D libfoo.so | grep sync
debian-armel:~#
* Solutions:
I'm going to submit a bug report for g++, but anyway I don't think we are
going to get a fix anytime soon,
I don't know if it is allowed for the Debian packaging rules to change the
compiling options for certain platforms. If it were the case, I could dive
into OSG's CMake build system and put a switch in order to deactivate the use
of intrinsics. We would use that switch only for armel.
We could also modify OSG's test for the availability of intrinsics in order to
not only test if a program using them could be compiled, but also if the
compiler is also able to link a simple program with a library using them.
This way we could have a platform independent test, not just something
specific for armel.
Awesome work :-) If you come up with a way to disable this with a CMake
option, I'll set it for armel only in the upcoming 2.8.1 package. As
long as it does not change the functionalities (only speed), it is
acceptable.

Bug#529091: openscenegraph: fails to build on armel "hidden symbol (...) is referenced by DSO"
Package: openscenegraph Version: 2.4.0-1.1 Severity: serious Justification: no longer builds from source At last, the armel build of 2.8.0-4 took place on May 10th. However it failed because the following error when building the first program on the suite that uses the library, osgviewer: /usr/bin/ld: ../../bin/osgviewer: hidden symbol `__sync_bool_compare_and_swap_4' in /usr/lib/gcc/arm-linux-gnueabi/4.3.3/libgcc.a(linux-atomic.o) is referenced by DSO /usr/bin/ld: final link failed: Nonrepresentable section on output It is the same error that the 2.8.0-1 release got on this platform in the past. I think the error is caused since the new atomic operations feature was incorporated to OpenThreads between the 2.4 and the 2.8 releases. Since it seems that nobody uses armel on the OSG list -- otherwise this error would come up several months ago --, one possible solution would be to deactivate the use of those intrinsics only for armel. This approach has however several disadvantages: - Seeing the CMakeLists.txt file, it seems that there is no way of deactivating that feature, since is not optional but configured automatically through tests. I could, however, ask for a way to do it on the mailing list. - It is almost a shoot in the dark, since we cannot test in a fast way if the fix is working (it seems that for armel the latency is almost two months). - We cannot know if the original error comes from OSG, CMake o armel's system libraries.
