Gnuplot

Installing

Mac Snow Leopard (OS X 10.6)

I installed gnuplot with the following configure line:

<source lang="bash"> ./configure \

--prefix=/Users/charles/pkg/gnuplot/4.4.3 \
--with-readline=/Users/charles/pkg/readline/6.1 \
--with-texdir=/Users/charles/Library/texmf/tex/latex/gnuplot \
CFLAGS="-I/Users/charles/pkg/readline/std/include -L/Users/charles/pkg/readline/std/lib"
CXXFLAGS="-I/Users/charles/pkg/readline/std/include -L/Users/charles/pkg/readline/std/lib"

</source.

I initially experienced the following errors during the linking process:

This caused a slew of "undefined symbol" errors:

This turned out to be a problem with Fink - I had accidentally installed a 32-bit version of Fink on a Snow Leopard operating system, which is 64-bit. Gnuplot then automatically attempted to build a 64-bit version of everything, and ran into problems when linking to 32-bit versions of libraries.
