Having problems compiling a fortran program which uses libplot. (linuxmint)

alexus88 · 03-23-2013, 12:41 PM

So, the title really describes it all. I would appreciate if someone could help me decipher what it is that I am doing wrong. I tried reinstalling and updating both gfortran and libplot, but I still cannot produce a result.

Any and all help is greatly appreciated. Thanks

----Below is what I type into the terminal

Code:

gfortran -o example orbits.f -L/usr/local/pgplot -lpgplot

----Below is what the terminal responds with

Code:

/usr/bin/ld: cannot find -lpgplot

install libpgplot ( pgplot)

you used

Quote:

gfortran -o example orbits.f -L/usr/local/pgplot -lpgplot

so is it there ? in /usr/local/pgplot ?
or is it in
/usr/local/lib ( where it should be , if using /usr/local)

also is this new FORTRAN ? or an older bit of code like fortran 77
Though 77 should have .f77 on the end of the code
