New root compilation: Undefined reference to <Method>

Folkert · November 26, 2007, 2:40pm

Hi all,

I compiled a new version of ROOT, version 5.17 on a SLC3 machine. Compilation works fine, but if I try to compile a test program (the program is empty, just a int main(){}), linking against the ROOT CORE library using:
g++ -I${ROOTSYS}/include -L${ROOTSYS}/lib -lCore test.cpp -o test
I get a lot of errors like:
/project/atlas/Users/fkoetsve/root/lib/libCore.so: undefined reference to `G__tag_memvar_setup’

The full error list is included.

These are my env variables:
PATH (the part for ROOT):
/project/atlas/Users/fkoetsve/root/bin:/data/atlas/offline/12.0.6/sw/lcg/external/root/5.10.00e/slc3_ia32_gcc323/root/bin
LD_LIBRARY_PATH:
/project/atlas/Users/fkoetsve/root/lib
ROOTSYS:
/project/atlas/Users/fkoetsve/root

The path where I compiled root is:
/project/atlas/Users/fkoetsve/root

Can anyone tell me what I did wrong? I did compile root before on my laptop, same version, and I did not get this problem. I configured it with the flags:
–enable-roofit --enable-pythia6 --with-pythia6-libdir=/project/atlas/Users/fkoetsve/pythia6
then typed make, which gave no errors.

Thanks for the help!
Folkert

You must add “-lCint” in your link sequence of libs.

Rene

Folkert · November 26, 2007, 2:54pm

That does give less errors, only 5:

/project/atlas/Users/fkoetsve/root/lib/libCint.so: undefined reference to dlerror' /project/atlas/Users/fkoetsve/root/lib/libCore.so: undefined reference todladdr’
/project/atlas/Users/fkoetsve/root/lib/libCint.so: undefined reference to dlclose' /project/atlas/Users/fkoetsve/root/lib/libCint.so: undefined reference todlopen’
/project/atlas/Users/fkoetsve/root/lib/libCint.so: undefined reference to `dlsym’
collect2: ld returned 1 exit status

I must add that originially I am compiling a program which uses somewhat more root libraries, and the original compile command is:

g++ test.cpp -o test -L $ROOTSYS/lib -I $ROOTSYS/include -lCore -lCint -lTree -lTreePlayer -lHist -lMatrix -lPhysics
which gives many many errors, almost all from libTree.so, some from libTreePlayer.so, like:

/project/atlas/Users/fkoetsve/root/lib/libTreePlayer.so: undefined reference to TFile::GetFileBytesRead()' /project/atlas/Users/fkoetsve/root/lib/libTree.so: undefined reference totypeinfo for TEmulatedCollectionProxy’

Does this mean I need to add more libraries?

Thanks,
Folkert

Found the solution in the release notes:
root.cern.ch/root/Version516.news.html
Under the heading of warnings. The root-config --lib command gives a bunch of the necessary libs (although it appears I don’t need all) What is the libNet library for? It doesn’t work without it…

Thanks for the help!

Hi,

[quote=“Folkert”]What is the libNet library for? It doesn’t work without it…[/quote]When you say “it doesn’t work without it” you mean you get error messages? Well - they should tell you what it’s needed for It’s probably required by linking against libCore.

Cheers, Axel.
