I cannot compile the tutorial’s TMVAClassification.C
After running $(root-config --cxx --cflags) TMVAClassification.C -o tmva_class $(root-config --glibs --libs)
, I receive errors from linker:
/usr/bin/ld: /tmp/ccxpOIRE.o: in function `TMVAClassification(TString)':
TMVAClassification.C:(.text+0x2f): undefined reference to `TMVA::Tools::Instance()'
/usr/bin/ld: TMVAClassification.C:(.text+0x1074): undefined reference to `TMVA::gTools()'
...
/usr/bin/ld: TMVAClassification.C:(.text+0x3efa): undefined reference to `TMVA::Factory::EvaluateAllMethods()'
/usr/bin/ld: TMVAClassification.C:(.text+0x401c): undefined reference to `TMVA::TMVAGui(char const*, TString)'
collect2: error: ld returned 1 exit status
I tried different permutations the position of libs path, source code, and output, but nothing helped.
I use Root v6.26.02.Linux-ubuntu20-x86_64-gcc9.4 ,
Ubuntu 20.04.4 LTS on WSL2 (5.10.102.1-microsoft-standard-WSL2),
gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0
