So far, so good. If you want to make sure that everything works as it should, try a 'make -k check' as well (CAUTION: It might take a while to complete). > Three variations of some statistical modules are created: e.g., > histogram.c, > histogram.l, and histogram.

On the risk that my limited understanding of OSX shows - you are aware that gsl is a *library*? It has a few executables as well, but by and large it is a library, intended to be linked against your code. BTW - where do you find 'histogram.c'? > I then try to compile modules separately.

The 'undefined symbols' are warnings from your linker - to get rid of them you have to provide it with the right library to link against. If you are using gcc, provide the -lgsl flag. Having said that, it is relatively useless (and indeed impossible) to compile something without a 'main' function into an executable. If you want to take a look at code that uses the gsl, go into the doc/exaples subdirectory of your gsl tree and have a look at the *.c files. Most (all?) of them are intended to be compiled into executables. -- Space -- the final frontier _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
