> Hi,
>
> My web app uses the PGPLOT module to access PGPLOT, which is a scientific
> plotting library commonly used in my field. It is a Fortran library, with
> a C wrapper around it, which is then wrapped in Perl. This works fine in
> my test scripts, producing the desired graphics.
>
> The library requires that the environment variable PGPLOT_DIR be set so it
> can find some required files. Running from the command line, I just set
> this in the shell, and PGPLOT works fine. Running in Apache, I see
> different behavior:
>
> When I set this in httpd.conf:
> PerlSetEnv PGPLOT_DIR /my/pgplot/directory
> my Perl programs can see the value in $ENV{PGPLOT_DIR}, but the PGPLOT
> library can't, and my code fails.
>
> When I set this in httpd.conf:
> <Perl>
> $ENV{PGPLOT_DIR} = q[/my/pgplot/directory];
> </Perl>
> my Perl programs can't see the value in $ENV, but the PGPLOT library can,
> and my code works.
>
>
> Can someone help me understand what the difference is between these two
> cases?
>
> Is the situation muddled because the PGPLOT library is a
> Perl-wrapped-C-wrapped-Fortran library? I'm not sure how the environment
> passing is supposed to work.
