but i can’t successfully compile the codes.
what’s the problem?
Your suggestions are appreciated.

The Warning in compiling Pythia6 is normal.
You seem to have problems when linking the shared lib.
I assume that you will get help from a MAC user.

Hi,

before compiling make sure you set:

export MACOSX_DEPLOYMENT_TARGET=10.4

Hi All.
thanks for your help. thank all very much.

i have compiled pythia6 successfully.
so next, i compiled root(cvs ver.)
"./configure --with-pythia6-libdir=$PYTHIA6"
when i "make"
i got some gfortran errors.
but i can “make cintdlls” and “make install” successfully.
and i can test the codes successfuly too,

"root [0] .L pythiaExample.C
root [1] makeEventSample(1000) "

without any problem.

so my question is what’s difference between g77’s and gfortran’s option?
if using gfortran, how can i modify the makePythia6.macosx in pythia6.
how to avoid these gfortran errors when i compiled the root source codes.

thank you.
regards,
Chen

btw: the gcc4 and gfortran are default compiler. g77 compiler is installed by using fink.

make

i got gfortran errors just like this:

Hi,

gfortran is not officially supported by us since the compiler is still too primitive to handle most of the old HEP fortran. We propose to still use g77.

The error about -y seems to be a gfortran installation error.

Cheers, Fons.
