Macro works OK, but aclocal says "macro `AM_PATH_GSL' not found in library"

Macro works OK, but aclocal says "macro `AM_PATH_GSL' not found in library"

[Dr. David Kirkby]

I copied the macro 'gsl.m4' from the GNU scientific library (latest
version 1.3). The macro tests for the presence, version and path of
the gsl library.

Running first automake and autoconf, no problems are reported. After
this, the macro works as expected. But 'aclocal' reports an error:

% automake
% autoconf
% aclocal
aclocal: configure.ac: 95: macro `AM_PATH_GSL' not found in library

autoreconf does likewise:

% autoreconf
aclocal: configure.ac: 95: macro `AM_PATH_GSL' not found in library


Can anyone offer any help? It is strange the macro works, yets
generates these error messages when running aclocal. I've put a
cut-down version of my configure.ac here and the gsl.m4 macro below
that (below the two rows of XXXXXXXXXXXXXXXXXXXXXXXX's) , just in case
someone on the autoconf mailing list can help and does not have gsl
installed.

Re: Macro works OK, but aclocal says "macro `AM_PATH_GSL' not found in library"

[Ronald Landheer-Cieslak]

Where does the macro "live"?
If you've put it in a file in a subdirectory (e.g. m4/gsl.m4) you should 
add the proper -I option to aclocal:
$ aclocal -Im4
so aclocal will search in that directory for the missing macros.

$ aclocal --help
Usage: aclocal [OPTIONS] ...


Generate `aclocal.m4' by scanning `configure.ac' or `configure.in'

   --acdir=DIR           directory holding config files
   --help                print this help, then exit
   -I DIR                add directory to search list for .m4 files
   --output=FILE         put output in FILE (default aclocal.m4)
   --print-ac-dir        print name of directory holding m4 files
   --verbose             don't be silent
   --version             print version number, then exit

Report bugs to <bug-automake@gnu.org>.

Does the above help any?

You can put "ACLOCAL_AMFLAGS = -I m4" into the toplevel Makefile.am so
that automake and autoreconf automagically pick it up there.

The macros are in the top-level directory where configure.ac lives, so
I'm surprised this is necessary. 

After making several changes along the lines of those suggested by
everyone here, I now have a configure.ac that creates a configure
script, without producting any error messages!! It also runs without any
error messages!! But alas my problems are not over, as the Makefile
exits with the error message

What error message would that be? I'd be (very) surprised if your macro 
call just got copied to the Makefile, so I'd WAG that there's a new error 
here :)

Please post the exact error message given by make.

Sorry, I have finally got it working. I changed so many things, so
many times that I lost track of what exactly the error message was.
Anyway, I seem at last to have configure.ac and Makefile.am that is
allowing for the compilation of normal and multi-threaded code
properly. I have some issues with code configured for distributed
processors, but that is another story. I'll post those issues once I
have tried some more to resolve them.
