These files are used to add OS, distribution and/or release specific
parameters, tests, etc. to ./configure
Brief instructions
begin with
#!/bin/sh
echo " Setting XXXXXX specific flag values"
All non error/warning echo's should be indented 8 spaces for neatness...
Common things to set are
LDFLAGS="${LDFLAGS} -L/usr/X11R6/lib"
CPPFLAGS="${CPPFLAGS} -lz -lm"
(note that you should always use those formats so that any other settings are
preserved). The ${} can be first (takes effect first) or last.
You can also use other shell commands, such as testing if a file exists:
if ! test -f /usr/X11R6/lib/libXpm.so; then
You can use case statements on the preset values target and CC to do more detailed
version specific settings (note target is set by config.guess):
case "${CC}" in
gcc* )
...stuff...
;;
esac
Finally, if you output a warning, set the flag value:
HAS_WARNING="yes"
You can do pretty much anything you can do in configure.
But you can not do all the things you can do in configure.in - you
can NOT use autoconf macros in here. If you really want to, look
at functions - there's a stripped down 'AC_CHECK_HEADER' function
(look at HPUX to see how to invoke it).
