The new version uses a shared library for the Explor functions, and cats the source file to the Fortran compiler along with a file that contains the “END” command rather than creating an intermediate file.
You’ll need git, autotools, libtool and g77 installed. On Fedora the command to install them is something like:
su -c "yum install git gcc-gfortran libtool autoconf automake"
Fetch the source code:
git clone https://robmyers.org/git/explor.git
Set up the build environment:
su -c "make install"
You can then make a test image:
This will print messages something like this:
Compiling example6.explor to example6
Running example6 with output to example6.ps
And if you open the resulting .ps file, you’ll see the image at the top of this post.
