I'm working on autobuilding a program which currently uses imake. One
thing I'm working on changing now is that there is a big .h file that has
many defines for defaults like:
#define EMERGENCY_NAME "/tmp/FOO.%i.save" /* %i --> pid */
#define BACKUP_NAME "/tmp/FOO.%i.backup" /* %i --> pid */
#define DEFAULT_SIZE "7000x5000" /* default layout size */
#define DEFAULT_MEDIASIZE "a4" /* default output media */
#define DEFAULT_CELLSIZE 50 /* default cell size for symbols */
Then there is a shell script that uses awk/sed to pull out these #defines
and make the documentation reflect the compiled in defaults. So my
question is when converting to autoconf should I do something like add
--with-emergency-name
--with-backup-name
--with-default-size
--with-default-mediasize
--with-default-cellsize
options? The autoconf manual seems to say that --with and --without are
for specifying specific external programs not so much for internal
defaults.
I chould also have configure.ac have lines like:
EMERGENCY_NAME=${EMERGENCY_NAME:-"/tmp/FOO.%i.save"}
and override via setting the environment variable. I don't much like
this, but this is how CFLAGS, etc get passed in.
So which is the recommended practices way to handle this with autoconf?
Thanks
