[Llvm-bgq-discuss] Linker error: undefined reference to `vtable for std::nested_exception'

[Michael Schlottke]

Hi Hal,

We tried to install the new version of clang on the BG/Q @ FZ Juelich from your rpms, which worked like a breeze (thanks again for your effors!). However, with the new installation we are not able to link even simple problems against libcxx, as all attempts end with the following error:

/bgsys/local/clang/r209570-20140527/libc++/lib/libc++.a(exception.cpp.o):(.toc+0x0): undefined reference to `vtable for std::nested_exception'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

It happens as soon as we try to compile & link a dummy program that has at least one std library include file. If we use bgclang++, the error does not occur, but it does when using either -stdlib=libc++ or bgclang++11.

Do you have any idea what the source of the problem could be? I attached a MWE and the output of running bgclang++11 with -v.

Regards,

Michael

P.S.: We had a driver/toolchain upgrade on JUQUEEN and thus our old clang installations are not working anymore. Maybe this could be related to the problem?
