PGPLOT subrountine library installation

royxu — Mon, 15 May 2006 22:33:08 GMT

Dear all,
How are you?
I am trying to install the PGPLOT library on my Linux server. I installed it and run the demos successfully. However when I compile the sample example (ex1.f), I met some technical problems in compiling PGPLOT.
The syntax I am using is:

$ f77 -o ex1 ex1.f -lpgplot
/usr/bin/ld: cannot find -lpgplot
collect2: ld returned 1 exit status

I confirmed that libpgplot.a is in the LD_LIBRARY_PATH. I don't know why it cann't find it. Can you provide any advice on how to fix this?

Thanks!

Roy

Is this an Intel compiler question, meaning that you have your environment set so that 'f77' invokes 'ifort'?

In general non-system link library paths should be explicitly specified in the command line, normally as -L. Most compilers will search directories listed in LD_LIBRARY_PATH as well, as if they were included in the system library paths. Could you have a type, or an extra space? Is it colon delimited? Are you running as root, which drops the LD_LIBRARY_PATH environment for security reasons?

Hi,
I am glad that I figured it out by changing the syntax to

f77 -o ex1 ex1.f -L/usr/local/pgplot -lpgplot -L/usr/X11R6/lib -lX11

Now it works. Thanks!
