I have a header file avcall.h which collects the results of autoconf
tests, so it is mentioned in AC_CONFIG_HEADERS.
I also want it to define the package version cpp macro, so I added
#if !defined(LIBFFCALL_VERSION)
# define LIBFFCALL_VERSION @PACKAGE_VERSION@
#endif
to it (there are several such headers, each has these 3 lines).
however, configure did not substitute @address@hidden
thus I added avcall.h to AC_CONFIG_FILES.
Right.
AC_CONFIG_HEADERS has to have a very specific format. You'd do
AC_DEFINE_UNQUOTED([LIBFFCALL_VERSION], ["$PACKAGE_VERSION"],
[Version of libffcall, for avcall.h])
and in avcall.h.in
#ifndef LIBFFCALL_VERSION
#undef LIBFFCALL_VERSION
#endif
but I'm not sure whether autoheader would destroy avcall.h.in, so
Peter's solution is preferred.
