Error regarding installing Pythia8

Looks like your installation has a mix of 32 bit and 64 bit library.
Your linker can not handle that.

in particular I guess that
/cm/local/apps/gcc/5.2.0/lib/../lib/libstdc++.so
is 32 bit, while the rest is 64bit (but It can also be the opposite)

Cheers,

Olivier

Hi Olivier,
                        thanks for your quick response. Then what is your suggestion ? How can I resolve this problem.

Regards,
Shiba

Hi,

I do not have any suggestions actually.
Pythia8 author might be able to give you more hint.

The only think I can suggest is to check which library are 32 bit from those which are 64 bit.
and see if you can change your path to have a consistent setup on that side.
One other suggestion is to force the 32 bit (or 64 bit ) compilation. This require to modify the makefile of Pythia8 (and therefore I let them to comment on that)

Cheers,

Oliver

Hi Shiba,

As Olivier suggests, you could try to force the 64 bit compilation by adding the option "--enable-64bit" to your configure command, e.g. use a configure command

 ./configure --prefix=/path/to/install --with-hepmc2=/path/to/hepmc --with-lhapdf6=/path/to/lhapdf --with-lhapdf6-plugin=LHAPDF6.h --with-gzip=/path/to/libz --with-boost=/path/to/boost --with-promc=/path/to/promc --enable-64bit

Please let us know if that helps.

Cheers,
Stefan

Hi Stefan,
                       thanks. sorry, Do I have to run above line From Madgraph home directory ?

Regards,
Shiba

Hi Stefan,
                          Are you saying to install Pythia8 separately and then link to MG5 ? I am guessing this from your suggestion.
Please clarify.

Thanks in advance.

Shiba
