Re: [Plplot-general] png plots

[M. F. <mfr...@vi...>]

I had previously installed
gd-1.8.1-4mdk.i586.rpm gd-devel-1.8.1-4mdk.i586.rpm
gd-utils-1.8.1-4mdk.i586.rpm

I went to rpmfind.net looking for the gd devel you recommended.
It was not to be found. Where can I find the rpms you recommended?

Thanks.
