Can't find pythia6 during root compiling(cmake)

[kdy]

Hi, I already installed root-6.26.06 on Ubuntu 22.04.
I also had installed pythia8 and root was built with pythia8 successfully.
recently I have to get pythia6 also. so I installed pythia6 first referenced https://root-forum.cern.ch/t/root-with-pythia6-and-pythia8/19211

pythia6.tar.gz
./makePythia6.linuxx8664(I use 64 bit Ubuntu)

pythia6 dir has…

and tried to rebuild root with pythia6.

when I was doing
cmake … Dall=ON

and my environment variables

Root didn’t recognize pythia6 several attempts.
Besides the instruction I added LD_LIBRARY_PATH:$PYTHIA6 (last line)
but the problem was not solved.
Does any solution exist? experts…

Welcome to the root forum.

The post you linked to contains de recipe. that’s does not help ? I see @bellenot also help in the past with this. May be he has some ideas.

First, I don’t see any pythia6 library in your directory. Then, try to use something like this (for example):

cmake ... -Dall=ON -DPYTHIA6_INCDIR=$HOME/pythia6 -DPYTHIA6_LIBRARY=$HOME/pythia6/pythia6416.so

I’m trying to download also pythia-6.4.28.f.gz
following the instruction of mehlhase here

but the link cannot be accessed.

wget http://www.hepforge.org/archive/pythia6/pythia-6.4.28.f.gz

so I searched another web page here
and I clicked pythia6.428.code and downloaded this

Is pythia6428.f identical with http://www.hepforge.org/archive/pythia6/pythia-6.4.28.f.gz??

and I have 1 more question.
my pythia8307 directory has lib directory

but pythia6 directory doesn’t have. Is that right?

@kdy

Is pythia6428.f identical with http://www.hepforge.org/archive/pythia6/pythia-6.4.28.f.gz??

I don’t know, did you try to compare them?

@kdy

but pythia6 directory doesn’t have. Is that right?

Yes

[kdy]

thx, You replied use the command

cmake … -Dall=ON -DPYTHIA6_INCDIR=$HOME/pythia6 -DPYTHIA6_LIBRARY=$HOME/pythia6/pythia6416.so

I’m tying also this. but my pythia6 directory doesn’t have pythia6416.so but has pythia6416.o
(See above!)
Is it right the command include pythia6416.so?

[bellenot]

Did you build pythia6 yourself? Was there any error? Building pythia6 should produce a library (libPythia6.so)

[kdy]

Yes, I see

I did only this

wget https://root.cern.ch/download/pythia6.tar.gz
tar -zxvf pythia6.tar.gz
cd pythia6
./makePythia6.linuxx8664

and my pythia6 directory has…

more procedure should be done?

[bellenot]

I’ll try and let you know

[bellenot]

OK, here is what I get:

As you can see, it produces libPythia6.so

[kdy]

omg…
Thank you very much.
I’ll do it again…

[kdy]

Yes, I have an error.

I found a bug report that seems to be related to this issue. here
