9.2.1 Portability Infrastructure
As I explained in 9.1.1 Project Directory Structure, I'll first create
the project directories, a toplevel directory and a subdirectory to put
the library sources into. I want to install the library header files
to `/usr/local/include/sic', so the library subdirectory must be
named appropriately. See section 9.1.2 C Header Files.
$ mkdir sic
$ mkdir sic/sic
$ cd sic/sic
I will describe the files I add in this section in more detail than the
project specific sources, because they comprise an infrastructure that I
use relatively unchanged for all of my GNU Autotools projects. You could
keep an archive of these files, and use them as a starting point
each time you begin a new project of your own.
