run pgplot in Fedora13

yba · 11-17-2010, 06:00 AM

I posted my similar question in September and got solved. Now I have another basic question. I install pgplot in Fedora13 where has no f77, no g77, only has f95 and gfortran. I run in csh shell, not bash. I install pgplot according to the instructions given by Dr.Pearson ( pgplot installation Manual version 5.3). What I did is as follows:
1.cd /usr/local/src/pgplot
2.cd sys_linux
3.cp g77_gcc.conf local.conf
4.vi local.conf (in the certain line to change the 'g77' into 'f95')
5.cp local.conf /usr/local/pgplot
6.cd /usr/local/pgplot
7./usr/local/src/pgplot/makemake /usr/local/src/pgplot linux local
8.make
9.make clean
10. setenv PGPLOT_DIR /usr/local/pgplot/
setenv PGPLOT_DEV /xwindow
setenv LD_LIBRARY_PATH $PGPLOT_DIR
11. ./pgdemo1

It works.
My question is: when I open another terminal, this new termonal is also
in the same directory (/usr/local/pgplot), I can not do ./pgdemo1 again, I must repeat the above steps from step 7 to step 10, then in this new terminal it works.

Dr.Pearson wanted me to ask experts to solve this question.

In addition, my own previous programs (which use pgplot) also must move
to the directory /usr/local/pgplot to compile and run.

Because I am an old man, not familiar with computers, so I need help.

seeing as fedora dose not use the folder /usr/local
it is NOT in the system $PATH

install it to just /usr
or
ad /usr/local ( and all the sub directory’s) to the system PATH in /etc/profile
seeing as you are using csh and not fedora's default bash ( /etc/bashrc)
there might be a system wide setting in /etc for csh

There is a 'csh.login' in /etc,# /etc/csh.login, it appears as follows:
--------------------------------------------------------------------
# System wide environment and startup programs, for login setup

if ( $?PATH ) then
#do not override user specified PATH
else
if ( $uid == 0 ) then
setenv PATH "/sbin:/usr/sbin:/usr/local/sbin:/bin:/usr/bin:/usr/local/bin:/usr/local/pgplot"
else
setenv PATH "/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin:/usr/local/pgplot"
endif
endif

setenv HOSTNAME `/bin/hostname`
set history=1000

if ( -d /etc/profile.d ) then
set nonomatch
foreach i ( /etc/profile.d/*.csh )
if ( -r $i ) then
if ($?prompt) then
source $i
else
source $i >& /dev/null
endif
endif
end
unset i nonomatch
endif
-----------------------------------------------------------------------

unfortunately, I do not understand C language, so I can not modify it.
Could you please tell me how to modify it?
Many thanks

1) The easy way is of course # yum install pgplot
... like already dealt with in your other pgplot thread :
http://www.linuxquestions.org/questi...ra13-827192/#5

2) f77, g77 : both are present in Fedora 13 : compat-gcc-34-g77

3) /home/<name>/<any-folder>/ may be a much more convenient location
for a special version.

4) Setting a permanent path for csh : A script can be added to /etc/profile.d :
The following is an example script from Slackware 12:
/etc/profile.d/jdk.csh

Code:

#!/bin/csh
setenv JAVA_HOME /usr/lib/java
setenv MANPATH ${MANPATH}:/usr/lib/java/man
setenv PATH ${PATH}:/usr/lib/java/bin:/usr/lib/java/jre/bin
