Question

If I just want to use the gsl_histogram.h library from Gnu Scientific Library (GSL), can I copy it from an existing machine (Mac OS Snow Leopard) that has GSL installed to a different machine (Linux CentOS 5.7) that doesn’t have GSL installed, and just use an #include <gls_histogram.h> statement in my c program? Would this work?

Or, do I have to go through the full install of GSL on the Linux box, even though I only need this one library?

Answer 1

Just copying a header gsl_histogram.h is not enough. Header states merely the interface that is exposed by this library. You would need to copy also binaries like *.so and *.a files, but it’s hard to tell which ones to copy. So I think the you’d better just install it on your machine. It’s pretty easy, just use this tutorial to find and install GSL package.

So there are surely a lot of libraries out there. However the particular one is Gnuplot. Using it you even do not need to compile the code, however you do need to read a bit of documentation. But luckily there is already a question about how to draw a histogram with Gnuplot on Stackoverflow: Histogram using gnuplot? It worth noting that Gnuplot is actually very powerful tool, so invested time into reading its documentation will certainly pay off.
