* doc: mention how to set early defaultsEric Blake2013-09-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Jonathan Lebon reported an issue to me off-list about a regression in libvirt's configure script, which I traced to a patch that rearranged code that was checking $with_library compared to the AC_ARG_WITH that actually set $with_library [1]. As the whole point of the libvirt patch was to refactor code to make maintenance easier by hiding the AC_ARG_WITH in a helper macro for a net reduction in lines, it makes sense to actually document how to check what value a variable has prior to the AC_ARG_WITH usage. Alas, although the functionality for this has been present in autoconf for ages, the documentation has been lacking.

(External Software) <AC_ARG_WITH>: Demonstrate how to use DEFAULTS diversion, for earlier defaults. (Package Options) <AC_ARG_ENABLE>: Likewise. * THANKS: Add Jonathan Lebon.

* AC_SUBST: don't underquote the variable nameNick Bowler2012-08-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the following: % cat >configure.ac <<'EOF' AC_INIT([test], [0]) m4_define([FOO], [baz]) AC_SUBST([FOO], [bar]) AC_CONFIG_FILES([test]) AC_OUTPUT EOF % cat >test.in <<'EOF' @FOO@ EOF This produces no error messages at autoconf time and none at configure time. Nevertheless, the substituted value of FOO is the empty string, instead of bar, as expected. Sure enough, in the output variables section of config.log, we see FOO='' instead of FOO='bar'. Looking at the generated configure script, we see that AC_SUBST has produced baz=bar in the output, instead of the expected FOO=bar. But this is the only place: everywhere else is still using FOO. * lib/autoconf/general.m4 (AC_SUBST): Add another layer of quoting. * THANKS: Update. Signed-off-by: Eric Blake <eblake@redhat.com>
* general: Sanitize IFS in EXIT trapAndreas Schwab2012-07-181-1/+1
| | | | | | | | | | IFS may be modified temporarily when the configure script receives a signal. Make sure the EXIT trap uses the standard value. * lib/autoconf/general.m4: Sanitize IFS in trap. * THANKS: Update. Copyright-paperwork-exempt: Yes
* doc: fix texinfo macro usagePatrice Dumas2012-07-181-0/+1
| | | | | | | | | | | | | | | | | The texinfo manual recommends avoiding the use of a trailing @c in any macro designed to be used inline (as is the case with our ovar and dvar macros). Furthermore, passing '@\n' in the middle of a macro call is much different than passing '@\n' between arguments of a @defmac for line continuation. * doc/autoconf.texi (ovar, dvar): Don't end macro with @c, since these macros are designed to be embedded in one-line usage. (Fortran Compiler): Don't split @dvar. * THANKS: Update. Reported by Stefano Lattarini. Signed-off-by: Eric Blake <eblake@redhat.com> Copyright-paperwork-exempt: Yes
