bug#17043: 24.3.50; xft isn't found on OS X 10.9.2 (Macports)

[Joe Corneli]

I've recently tried to configure Emacs from bzr to build from source on
OS X 10.9.2 under X11.  But ./configure isn't finding my xft library:

 [...]
 checking for xft >= 0.13.0... yes CFLAGS='-I/opt/local/include
 -I/opt/local/include/freetype2 -I/opt/local/include
 -I/opt/local/include/freetype2 -I/opt/local/include '
 LIBS='-L/opt/local/lib -lXft '
 checking for XRenderQueryExtension in -lXrender... yes
 checking for X11/Xft/Xft.h... no
 [...]
   Does Emacs use -lxft?                                   no

Here's what I see when I run 

$ port contents xft2
Port Xft2 contains:
  /opt/local/include/X11/Xft/Xft.h
  /opt/local/include/X11/Xft/XftCompat.h
  /opt/local/lib/libXft.2.dylib
  /opt/local/lib/libXft.a
  /opt/local/lib/libXft.dylib
  /opt/local/lib/pkgconfig/xft.pc
  /opt/local/share/man/man3/Xft.3.gz

Given the above, I'm not sure why the port isn't found/used.  Is it an
incompatible version?

$ port -v installed xft2
  Xft2 @2.3.1_1 platform='darwin 13' archs='x86_64'
  Xft2 @2.3.1_1+universal (active) platform='darwin 13' archs='i386 x86_64'

This looks like the relevant part.  I'll also mention this to the
MacPort maintainer for Xft2.

I found a workaround, but the maintainer of the Xft2 port said that
it isn't correct.

"That sounds like the problem you'd get with software that is not
compatible with freetype 2.5.1 and later. The diff you proposed is not
the correct fix. Consult the freetype documentation for the proper way
to include freetype headers."

My workaround patch against /usr/X11/include/ft2build.h was as below:

Actually, as pointed out by the maintainer of the Macport in question,
Emacs is looking at the system Xft, not the one installed with macports.
The system version is out of date.

So it sounds to me like you need to set CPPFLAGS, LDFLAGS before you run
configure, so that emacs finds the versions you want it to find. At the
moment I don't see an Emacs bug here.

Firstly, yes, this does seem to help, but it didn't solve the problem.

$ export CFLAGS='-I/opt/local/include/ -I/opt/X11/include/ -I/opt/local/lib/'
$ export LDFLAGS='-I/opt/local/include/ -I/opt/X11/include/ -I/opt/local/lib/'
$ export CPPFLAGS='-I/opt/local/include/ -I/opt/X11/include/ -I/opt/local/lib/'

For example, Emacs can now find libjpeg and giflib libraries that it
wasn't able to find, before, and it also tries to include the MacPorts
version of Xft.  However, here, I still get an error:

In file included from /opt/local/include/X11/Xft/Xft.h:39:
/opt/X11/include/ft2build.h:56:10: fatal error: 'freetype/config/ftheader.h' file not found

Patching this file as I indicated before solves the problem.

I'll try addressing that point to the upstream developer for freetype.

The *possible* Emacs feature request: Shouldn't it be able to detect
that it's being built against MacPorts, and set the relevant flags
automatically?

It looks to me like the /opt/local version is mistakenly including an
/opt/X11 version; but I'm not familiar with MacPorts.

I think this is outside the scope of the Emacs configure script.
Perhaps there is a MacPorts tool to set up the environment for building.

We used to auto-add Fink's /sw directories, so we could consider doing
the same for MacPorts's /opt.  But IIUC we don't do that any more, so
before doing it for /opt we should try and remember why we don't do it
for /sw any more.

Because some people have both Fink and MacPorts installed, they are
mutually incompatible, and there's no way for us to tell which one, if
any, they want to use in any particular build (nor is it our job to do
so IMO). http://debbugs.gnu.org/2280

Bu anyway, this is wishlist item http://debbugs.gnu.org/11507 .

Perhaps those are not the right settings.
Perhaps these days you also need to export PKG_CONFIG_PATH pointing to
the right MacPorts location.
I'd consult MacPorts documentation related to building software.
Perhaps there is a script you can source to set up a build environment.

You're correct about that!  The MacPorts maintainer sorted it out for
me.  Here are the correct settings:

export LDFLAGS="-L/opt/local/lib"
export CPPFLAGS="-I/opt/local/include"

This got things to build without any patches.  Sorry for the noise!  

I will however underline my support for http://debbugs.gnu.org/11507.

These people are weird, I know, I used to be one of them :-).
