gnutls/gnutls.h: No such file or directory

[Leo]

I have gnutls installed with prefix /usr/local/unix/gnutls and emacs
trunk used to build fine on OSX with:

PKG_CONFIG_PATH=/usr/X11/lib/pkgconfig:/usr/lib/pkgconfig:/usr/local/unix/gnutls/lib/pkgconfig:/usr/local/unix/dbus/lib/pkgconfig ./configure --without-jpeg --without-gif --without-tiff

But today I am getting this error:

What does `pkg-config --cflags gnutls' say on your system?  If it's
blank (as the src/Makefile snippet implies), then it seems `pkg-config'
is not giving the right include path to the compiler.

I was able to build and use gnutls with zlib 1.2.3 (default in OSX) but
the gnutls.pc requires zlib like this:

Requires.private: zlib

So pkg-config --cflags gnutls gives this error:

Package zlib was not found in the pkg-config search path.
Perhaps you should add the directory containing `zlib.pc'
to the PKG_CONFIG_PATH environment variable
Package 'zlib', required by 'GnuTLS', not found

BTW, zlib.pc is not found on OSX.

It seems like the problem is with the zlib in Mac OS X then.  I don't
think Emacs can work around the problem; it's probably a Mac OS X bug.
Do you know?  Can you report it, if so?

You can write a custom zlib.pc and publish it on the Emacs Wiki if you
want to help other users in the same situation.

I have worked around this by commenting out the line: Requires.private:
zlib in gnutls.pc.

...so is it a bug in GnuTLS then?  Meaning, is requiring zlib on MacOSX wrong?

I see you started a discussion on gnutls-devel already.  Thanks :)

AFAICS, the problem is that assuming that common libraries will be
known to pkgconfig is bogus on MacOSX.  In the case in point, on
MacOSX, libz is a system library in /usr/lib, and there will be no
zlib.pc provided, so pkgconfig will get confused.  OTOH, if you have
the MacPorts version of libz installed, there will be a proper zlib.pc
installed in /opt/local/lib/pkgconfig, and it will all just work.

Presumably this also works if you have a private build in /usr/local
too.
