pgplot

[Danichka]

Hello

I have been trying to install the pgplot correctly but I'm having troubles with the libraries I guess....
demo programs run fine (for exemple ./demo1) but I'm not able to compile anything.

Here is the error I'm getting when I type
$ gfortran ./Fortran/src/pgplot/examples/pgdemo1.f

/tmp/cco0RO8P.o: In function `pgex15_':
pgdemo1.f.text+0xd0): undefined reference to `pgbbuf_'

pgdemo1.f.text+0x6aa): undefined reference to `pgebuf_'

and so on....
all those functions above are in the folder /home/dana/Documents/Fortran/src/pgplot/src/ which is in my PATH.

here is my PATH and my LD_LIBRARY_PATH. What am I missing?

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/dana/Documents/Fortran/src/pgplot/examples/:/home/dana/Documents/Fortran/src/pgplot/src/:/usr/lib32/:/usr/bin/ld:/home/dana/Documents/Fortran/src/pgplot/src/:/home/dana/Documents/Fortran/pgplot

$ echo $LD_LIBRARY_PATH
/home/dana/Documents/Fortran/pgplot/:/usr/lib/x86_64-linux-gnu/:/usr/lib/syslinux/com32/include/math.h:/home/dana/Documents/Fortran/src/pgplot/src/:/usr/lib32/:/usr/bin/ld


/tmp/cco0RO8P.o, /tmp/cco0RO8P.o, and so on
are nowhere in my computer...

I'll be very grateful for any help I can get.

Thank you very much!

It seems you don't install PGPLOT as a library (from the sources) and don't select this library in the command line.

Read PGPLOT UNIX installation instruction carefully:

http://www.astro.caltech.edu/~tjp/pgplot/install-unix.html

 

[FJacq]

If pgplot is correctly installed, then you need a link option -lpgplot (or a similar name) in your command :

$ gfortran ./Fortran/src/pgplot/examples/pgdemo1.f -lpgplot

Instead of -lpgplot, you can also provide directly the path to the library (something like /.../libpgplot.a in replacing ... by the correct path).

Thank you François. I also had to add -lX11 and -lpng.
