Of course the line above won't do anything, but you get what I mean. Now
imagine that instead of 2 libraries, I have 10!!! It's really annoying to
have a very big command line with all those arguments. I've been hard-coding
these in the Makefile.am but I don't think that's the best approach. Can
anyone point me to the way it's done? Thank you all,
If this is for use on your own machine, then you should set up a
config.site file. By default, the file resides at
$prefix/share/config.site.
I have attached a config.site that I use for my own purposes. Perhaps
it will give you some ideas.
