I built mozilla from the CVS source last night (April 16, 2003) on Linux.  My
system has a version of freetype2, which Mozilla cheerfully detected during its
configuration process:
  checking for freetype-config... (cached) /usr/bin/freetype-config
  checking for FreeType - version >= 6.1.0... yes
However, MOZ_ENABLE_FREETYPE2 is not enabled in mozilla-config.h

Reproducible: Didn't try

Steps to Reproduce:
1. Download a source tarball (I used the 1.4a source)
2. Install the .mozconfig file I will attach as attachment #1 [details] [diff] [review].
3. make -f 2>&1 | tee make.out
4) dist/bin/mozilla

Actual Results:  
Mozilla downloaded the latest CVS, configured, and built.

When I started mozilla, I got the warning:
  WARNING: freetype not compiled in, file nsFT2FontNode.cpp, line 51

There is no MOZ_ENABLE_FREETYPE2 defined in mozilla-config.h.

Expected Results:  
Had freetype2 support compiled in.  Not displayed the warning.  Had
MOZ_ENABLE_FREETYPE2 defined in mozilla-config.h.

I'm attaching the make.out file (make's output) as attachment #2 [details] [diff] [review].

The output from the make command, bzip2 compressed

The uncompressed version is long: 2 MB; 31,000 lines.
The bzip2'd version is 172 KB.
When changing configure options, you need to run a 'make distclean' between
builds.  The MOZ_ENABLE_FREETYPE2 define is set by the local Makefile based upon
the MOZ_ENABLE_FREETYPE2 environment definition.  I don't see nsFT2FontNode.cpp
being recompiled in your log so it appears to have been compiled already with a
previous configuration.

There's no logic in the local Makefile to make sure that the files which depend
upon the local -DMOZ_ENABLE_FREETYPE2 define are rebuilt when the env variable
changes.  Either -DMOZ_ENABLE_FREETYPE2 needs to be moved up to the global
header or a local header needs to be generated with that define.
Ever confirmed: true
Summary: CVS Build of mozilla: MOZ_ENABLE_FREETYPE2 unexpectedly not defined → gfx freetype sets local defines which are not tracked by the dependency system

Haven't tested the code changes but this is the basic idea for the build system

non-global defines v1.0 (checked in)

This is just the generic code to remove non-global defines from

LXR output for searches for USE_FREETYPE, FT2_, and MOZ_ENABLE_FREETYPE2

Thanks to Christopher Seawood for Comment #3.  I could not bear the thought of
doing a "make distclean" and then presumably waiting for hours for another
build, so I cheated.  

First, I used LXR to search for all the places in the source code that mention
USE_FREETYPE, FT2_<anything>, and MOZ_ENABLE_FREETYPE2.  This gave me the
attached file:	(see my next attachment for more)

Awk program to process the list of files referring to MOZ

I then wrote a bit of awk to pull out the file names alone and generate a shell
script with a bunch of lines of the form:
   touch <filename-affected-by-config-change>
Here it is.

The Bourne Shell script that drives the awk program.

I drive the awk script with this little bit of Bourne shell.

I did manual review on the output until I was happy with it (special-cased some
files that didn't need touching), and then piped the output through "sh".  

At any rate, this probably saved me a lot of waiting, even given the time to do
some manual review, and I thought I'd share the trick.	Obviously this is not a
useful general solution to the problem -- but it can be a timesaver.

This patch generates a gfx/gfx-config.h file at configure time which contains
the gfx specific defines.  Atm, that's just MOZ_ENABLE_FREETYPE2.
