Building root, Issue with bin/thisroot.sh

ROOT
41

I see that the flag -fPIC is there while compiling ClangInternalState.cpp.o. So, I run out of ideas for the time being. :frowning:

Hi Pere,
do you think this could help?

Thanks for the suggestions. I think we need to investigate the visibility of the symbol _ZNK5clang12CapturedDecl7getBodyEv
Can you now from the build directory do:

cd interpreter
find . -name *.cpp.o -exec nm {} \; |  grep _ZNK5clang12CapturedDecl7getBodyEv

In SLC6 I get all weak symbols for this.

0000000000000000 W _ZNK5clang12CapturedDecl7getBodyEv
0000000000000000 W _ZNK5clang12CapturedDecl7getBodyEv
...

Can you also tell me the version of the linker

ld --version
44

Thanks

There seem to be ld patches after 2.17 for relocation errors, see:

gcc.gnu.org/bugzilla/show_bug.cgi?id=65248
bugs.debian.org/cgi-bin/bugrepo … bug=503052

Maybe try to build by yourself the binutils package, and retry then with some extra flags in the configuration or something like alias ld="/opt/binutils/ld" …

Hi,

Is this the problem reported below:

Thanks
