problem with autoconf && PKG_CHECK_MODULES

[Matthias Apitz]

Hello,

The SVN trunk of OPAC is using 'autoconf' for creating 'configure' and
Makefiles;

it seems that it can't expand PKG_CHECK_MODULES(...) in configure.ac and
I have investigated that:

I have installed on my 7.0R box:

# pkg_info | fgrep pkg-config-0.22_1
pkg-config-0.22_1   A utility to retrieve information about installed libraries

and this packages provides the following files:

# pkg_info -L pkg-config-0.22_1
Information for pkg-config-0.22_1:

Files:
/usr/local/man/man1/pkg-config.1.gz
/usr/local/bin/pkg-config
/usr/local/share/aclocal/pkg.m4

the file /usr/local/share/aclocal/pkg.m4 contains the definition of
PKG_CHECK_MODULES():

# fgrep PKG_CHECK_MODULES /usr/local/share/aclocal/pkg.m4
# to PKG_CHECK_MODULES(), but does not set variables or print errors.
# Similar to PKG_CHECK_MODULES, make sure that the first instance of
# this or PKG_CHECK_MODULES is called, or make sure to call
# PKG_CHECK_MODULES(VARIABLE-PREFIX, MODULES, [ACTION-IF-FOUND],
# PKG_CHECK_MODULES might not happen, you should be sure to include an
AC_DEFUN([PKG_CHECK_MODULES],
...

autoconf is /usr/local/bin/autoconf and in real through the wrapper:
...
+ exec /usr/local/bin/autoconf-2.61

which does not read /usr/local/share/aclocal/pkg.m4 as I've proofed
with 'ls -lu /usr/local/share/aclocal/pkg.m4'
that's why PKG_CHECK_MODULES is not expanded by autoconf and the result
is an error in running configure;

any ideas?
