There must be something not going too well in the AC_REQUIRES of
ltld.
In the attached configure.ac, some macros are issued out of order,
which
results in, for instance, shrext_cmds being used before its
definition:
[...]
I have a simple work around: instead of
AC_DEFUN([URBI_LTDL], [my macro])
I have
AC_DEFUN([URBI_LTDL], [m4_fatal([should never be used])])
m4_define([URBI_LTDL], [my macro])
The first line is to have aclocal notice that the macro is defined
in an
m4/ file, and the second is to avoid that URBI_LTDL define an
AC_REQUIRE
boundary. I don't remember the details, but it seems suspicious to
me
that code using shrext_cmds is emitted before the contents of my
macro.
Either somewhere there are m4_define that should be AC_DEFUN to
define
the AC_REQUIRE barriers (an error in Libtool), or when a macro OUTER
invokes a macro INNER which requires REQUIRED then REQUIRED is output
before OUTER, which seems wrong to me (an error in Autoconf).
Without having tested it, this looks like another instance of
<http://thread.gmane.org/gmane.comp.sysutils.autoconf.bugs/6421/focus=6429

yes, I agree it looks very much the same.
Thanks!
