Hello!
I installed ROOT version 5.15/02 on Kubuntu with configuration:
./configure linuxdeb --enable-pythia6 --with-pythia6-libdir=/usr/lib
I can load necessary Pythia6 library
root [0] gSystem->Load(“libEG”);
root [1] gSystem->Load(“libPythia6”);
root [2] gSystem->Load(“libEGPythia6”);
but error occurred when I tried to create instance of TPythia6:
root[3] TPythia6 * b = new TPythia6
/usr/local/root/bin/root.exe: symbol lookup error: /usr/local/root/lib/libEGPythia6.so : undefined symbol: pythia6_common_address
