Re: [mesa-users] compiling pgplot on Snow Leopard - strncpy argument problem in grfileio, grtermio

[Steve K. <sd...@ia...>]

Hi Frank, Bill-

Thanks for your responses - I was able to solve this problem.  

Indeed, the warnings about strncpy were not fatal.  What was killing things was the 'ar ru' part of the makefile where the library libpgplot.a was being archived/ranlib-ed
More specifically, after running 'makemake . osx gfortran-gcc' I replaced the line 687 of the resulting makefile with
          libtool -s -o libpgplot.a \
and then all went well.  This tip came from the following website:
  http://iparrizar.mnstate.edu/~juan/urania/2009/10/23/pgplot-on-snow-leopard/

By the way, I'm currently using gfortran 4.5.2 and gcc 4.5.2, latest Xcode from SL 10.6.7 / Software Update.

Cheers,
Steve

I'm running mesa-star just fine on my MacPro, compiled with gfortran (4.5.2), and would like to implement the pgplot window displays.  The problem is when trying to compile pgplot (with the supplied source in the utils directory) the fortran routines all compile, but the some .c routines throw the error (i've removed the directory paths from the log to keep it simple):
