Programming

Hi All,

I have a makefile for a graphing program utilizing the 'plotutils' pacakage on cygwin/x11. However, when I run the make it can't find the following libraries:

-lplot
-lpng

Have the library names changed or do i need additional libraries to reference?

for -lpng, you need to install libpng. I'm not sure whether you need to install libpng-dev on cygwin or not.

For -lplot, I'm not familiar with it but a cursory google search suggests installing plotutils. Again, I'm not sure if there's anything like a -dev package you need to install too.

[edit] definitely plotutils-dev and libpng-dev. Installing the libraries alone is enough to use them, but not sufficient to compile with them.

Thanks for that. I think it does have something to do with the -dev install.

Does anyone know where I can get that for cygwin/x11? I tried to reinstall plotutils from source but got an error. Btw, I am on Windows 7 maybe there is some permission error, or something?

the plotutils-dev and libpng-dev binaries should be the libraries you need. Install them the same way you installed the other binary packages. You should install them alongside libpng and libplot.

Like most binary distributions, cygwin seperates packages into the part you just need to run it and the part you just need to compile with it. So to compile with -lpng you need both parts.
