Re: Functions used by init before defined

Hi, Eric.

I am not sure about pasting in my configure.ac as my usage of Autoconf is a
bit wild.  I do suspect that something changed within Autoconf itself, as
my scripts worked fine with 2.53 but the problems started occurring after I
upgraded to 2.69 which is the latest.  I use a lot of includes via
aclocal.m4 to pull in macros that I define.  Could this have anything to do
with it?

In the meantime, I'll work on trying to get the smallest possible example
that shows this problem.  You really don't want to look at my full script.

 In autoconf, AC_INIT has to come first.  Anything appearing before
 AC_INIT is treated as going to diversion -1; so while it might affect m4
 definitions, it is not carried through to the resulting configure file.
  That would explain why pasting the functions in your configure.ac
 earlier than AC_INIT didn't make a difference.

Functions used by init before defined

2013-04-08 Thread jeremy
Hi,

I'm having a strange issue with Autoconf which involves a few built-in
functions.  They are not being found.  Basically, if I run autoconf on my
configure.in it complains about that as_fn_set_status and as_fn_exit are not
being defined.  Looking in the generated configure script, indeed these are
used at the top but defined at the bottom.  They are used very early in the
script, apparently by the call to AC_INIT.  So my (very hacky) solution is
simply inserting these two functions at the top of the script, and then the
script runs fine.  Now, on the other hand, I have another configure.in
script that seems to work fine with the same Autoconf version, so I am a bit
confused.

It was also somewhat confusing that copying these methods and putting them
at the top of my configure.in script did not seem to do anything as they are
apparently ignored and defined in the same place in the output regardless.  

So, I guess my questions are:

What are the possible causes of this misordering?

Is it my fault or Autoconf's?

What is the best way to make sure this doesn't happen?

My Autoconf is 2.69 with m4 1.4.16 and automake 1.12.6, which I think are
all the most current versions.

Thanks.

--Jeremy
