I would like to plot directly to an animated gif in gnuplot. From the FAQ: http://www.gnuplot.info/faq/faq.html#SECTION00056000000000000000 gnuplot needs to be linked to gd 2.0.29 or newer to do so
I have no idea how to check this other than gnuplot -V which doesn't help
Hi Ryan. According to "port info gnuplot", the gnuplot port requires the gd2 port. And according to "port info gd2", the gd2 port is currently at 2.0.33. (I'll update it to 2.0.34 shortly.) So you should be fine. More generally, you can use "otool -L" to determine what libraries another library or program is linked with; this is similar to the "ldd" command on Linux. Although the gnuplot port says it requires the gd2 port, that's no guarantee that the gnuplot binary actually uses the MacPorts gd2 library (though that's what it should mean). To verify that this is in fact the case, use otool -L. I don't use gnuplot so I don't know what its binary is called, but on the assumption that it's called "gnuplot" and is in the usual /opt/local/ bin location, you would run otool -L /opt/local/bin/gnuplot and see if something starting with /opt/local/lib/libgd is listed. If it is, you're fine. (And if it doesn't, then that's a bug that you should report to us.)
