I want to install pgplot on my PC. My Pc is running an intel i7-860. I install Fedora13 (X86_64 version). there is no g77_gcc in fedora13, it has only gfortran_gcc. I have edited the 'g77_gcc.conf' by copying it to'local.conf' and change 'g77' into 'gfortran', and follow all the installation instructions of pgplot. For examle, I did:
/usr/local/src/pgplot/makemake /usr/local/src/pgplot linux local.conf.
It seemly go through to the last step correctly, but the last step
'./pgdemo1' failed. It showes the same error message as other friends
showed in 2008 in Fedora10:
error while loading shared libraries: libpgplot.so: cannot open shared object file : No such file or directory

In fact it does exists, and if I do
'cp libpgplot.so /usr/local/lib',
it showes that the file already exists. I overwrite it, no use at all.
Still the same error message.
In google I find an item to teach 'how to install pgplot in 'gfortran_gcc',
I follow its instructions step by step, but at last, pgplot still does not work.
I am an old man, not familiar with computer. Could some friend help me to solve the problem.
Many thanks

pgplot is not bundled with the standard repository, if you know of a repository that includes pgplot then that would be useful information for the OP.

gfortran provides backward compatibility with g77 and so I don't think that your problem is with the compiler.

I'm wondering if there are any file permission problems or was there a problem with SELinux?

is there a file called " libpgplot.so "
it should be in /usr/lib
BUT and this is most likely what happened
the software installed into
/usr/local
Fedora DOSE NOT USE /usr/local

i use " --prefix=/usr" always in the configure
or CHANGE the makefile's if a makefile program

look in /usr/local/lib and see if it is there

yba : Welcome to LQ. .. .. ..

You should try this : # yum search 77
Lots of F77 stuff, and the first hit is the f77 compiler :
"compat-gcc-34-g77.x86_64 : Fortran 77 ... compiler"
( # 'yum search gcc' will also show it.)

The easy way : # yum install pgplot
(libgfortran x86_64 4.4.4-10.fc13 is installed as dependency.)
... Indicates : it was compiled with gfortran ( too ).

The package 'pgplot' is in the 'rpmfusion-nonfree' repo.

My bad. I entered pgplot in the yumex search bar and saw it come up; didn't look at the repo (rpmfusion-nonfree, as indicated by knudfl). I always install the rpmfusion-free and rpmfusion-nonfree repos with Fedora.

The most frequent problem with pgplot installs is not setting the LD_LIBRARY_PATH variable, which tells the OS where to go looking for shared object files (like libpgplot.so).

Add the following to the end of your .bashrc file
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:xyx
export LD_LIBRARY_PATH

where xyz is the actual directory where libpgplot.so is located.

Hope this helps.

setting the "LD_LIBRARY_PATH"
only if you install it in a non standard location
fedora considers /usr/local as non standard

i normally install programs that I build on a partition that / is not on ( easy reinstall if i fubar the os)
such as /usr/DATA/suse or /usr/DATA/cent


because of this i very often need to set that PATH
fedora set it is ~/.bash_profile
or system wide in /etc/profile
