pgplot installation in fedora 10

pratyuze · 01-15-2009, 12:05 PM

i recently installed pgplot in fedora 10. while the compilation goes on smoothly, when I try to run the demo files like pgdemo1 etc, it says

./pgdemo1: error while loading shared libraries: libpgplot.so: cannot open shared object file : No such file or directory

what do i do?? i can see libpgplot.so is present in the directory...

also, how and where do you find X11 libraries on fedora 10? is it already installed? if not where do i get them?

thanks!

p.s: i am new to linux

Doing the command './pgdemo' , pgdemo will look
for libpgplot.so in the "LD_LIBRARY_PATH" only,
which probably is /lib/, /usr/lib/, /usr/local/lib.

'su' .. 'make install' will install the libs, etc.
in /usr/local/ and you wiil be able to use ./pgdemo .
....
'rpm -qa | grep libX11' will show installed libX11 .
'rpm -ql libX11' will display the files.

but libpgplot.so is in the same directory from where i am trying to execute ./pgdemo. isnt tht supposed to work?

and could you be more specific about the use of "make install" please? i logged in as the super user. but is there a particular directory where i go to execute make install? i am not sure if i have understood you correct. when i type in make install, it says make: ***No rule to make target 'install'. Stop.

Thanks

No, see # 3.

I guess, you will have a 'Makefile' in pgplot/
( the top directory )
May be, you will run 'make install' in that directory.

Or this
'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/pratyuze/ \
pgplot/"path-to-directory-with-libpgplot.so"/
( replace everything with the actual path )
to have libpgplot.so in a traceable path.

And finally this option : cp libpgplot.so /usr/local/lib

One of the above options should work.
