Werner Lemberg a32758f27c * builds/unix/configure.raw: Simplify. 2014-03-05 08:02:46 +01:00
suzuki toshiya 382f3ef103 Fix a bug in configure in library dependency setting

2014-03-05 10:20:16 +09:00
Werner Lemberg f48f7dc84b Minor fix for `make devel'.
* builds/freetype.mk (INCLUDE_FLAGS) [DEVEL_DIR]: Don't use
pkg-config for bzip2 since not all GNU/Linux distributions have
`bzip2.pc' (and the header file `bzlib.h' is located in /usr/include
normally).
2014-03-04 04:40:07 +01:00
Werner Lemberg 7ac76b50da Fix several clang static analyzer dead store warnings.
* src/autofit/afhints.c (af_glyph_hints_reload,
af_glyph_hints_align_weak_points): Remove unnecessary assignments.

* src/bdf/bdflib.c (bdf_font_load): Ditto.

* src/pshinter/pshalgo.c (psh_glyph_compute_extrema,
psh_glyph_interpolate_other_points): Ditto.

* src/type1/t1load.c (T1_Set_MM_Blend): Ditto.

Werner Lemberg 93ebcbd0ac Rewrite library option handling in `configure'; improve `freetype-config'.
o Introduce `auto' value for `--with-XXX' library options; this is
  now the default.

o First use `pkg-config' for library detection, then fall back to
  other tests.

* builds/unix/configure.raw (--with-zlib, --with-bzip2, --with-png,
--with-harfbuzz): Rewrite.
Use new `xxx_reqpriv', `xxx_libpriv', and `xxx_libstaticconf'
variables to collect data for `freetype2.pc' and `freetype-config'.
(FT2_EXTRA_LIBS): Renamed to ...
(ft2_extra_libs): This since it gets no longer substituted.
(REQUIRES_PRIVATE, LIBS_PRIVATE, LIBS_CONFIG, LIBSSTATIC_CONFIG):
New output variables, replacing `XXX_PKG' and `LIBXXX'.
Add notice at the end of `configure' showing the library
configuration.

* builds/unix/freetype-config.in (--static): New command line
option.
(libs): Updated.
(staticlibs): New variable, to be used if `--static' is given.
* builds/doc/freetype-config.1: Document `--static'.

* builds/unix/freetype2.in, builds/unix/unix-def.in: Updated.
2014-03-03 07:13:45 +01:00
Werner Lemberg e962a914fd Avoid `long long' warnings with older gcc compilers.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>.

* builds/unix/configure.raw: Don't use gcc's `-pedantic' flag for
versions < 4.6.  This is especially needed for Max OS X since this
OS runs a gcc variant (or emulation) based on version 4.2.1.
2014-03-01 21:00:02 +01:00
Werner Lemberg 6030a9f755 * docs/INSTALL.CROSS: Revised and updated. 2014-03-01 14:01:12 +01:00
Werner Lemberg 646db05dfd Make `make clean' remove `freetype2.pc'.
This is a generated file at build time, not configure time.

* builds/unix/unix-def.in (DISTCLEAN): Move `freetype2.pc' to ...
(CLEAN): This variable.
2014-03-01 12:48:07 +01:00
Werner Lemberg 00c79ed968 Use pkg-config for detecting libpng and libbz2 also.
* builds/unix/configure.raw (HAVE_PKG): New variable.
Search for libbz2 using `pkg-config'; s/BZ2/BZIP2/.
Search for libpng using `pkg-config'.
Fix definition of `LIBHARFBUZZ' variable.
* builds/unix/freetype-config.in ($libs): Updated.
* builds/unix/freetype2.in: Add `URL' field.
Update `Requires.private' and `Libs.private'.
* builds/unix/unix-def.in: Updated.
2014-03-01 12:32:20 +01:00
Werner Lemberg 86026a47b3 Add configure support for HarfBuzz.
* builds/unix/pkg.m4: New file.
* builds/unix/configure.raw: Search for libharfbuzz using
`pkg-config'.
Add `--without-harfbuzz' option.
* builds/unix/freetype-config.in, builds/unix/freetype2.in,
builds/unix/unix-def.in (freetype-config, freetype2.pc): Handle
HarfBuzz.

* docs/INSTALL.UNIX: Document interdependency of Freetype with
HarfBuzz.

2014-02-28 09:25:57 +01:00
Dave Arnold 135c3faebb Fix Savannah bug #41697, part 2.
* src/cff/cf2ft.c (cf2_initLocalRegionBuffer,
cf2_initGlobalRegionBuffer): It is possible for a charstring to call
a subroutine if no subroutines exist.  This is an error but should
not trigger an assert.  Split the assert to account for this.
2014-02-28 07:45:07 +01:00
Dave Arnold 0eae6eb064 Fix Savannah bug #41697, part 1.
* src/cff/cf2hints.c (cf2_hintmap_build): Return when `hintMask' is
invalid.  In this case, it is not safe to use the length of
`hStemHintArray'; the exception has already been recorded in
`hintMask'.

Werner Lemberg a2b5f66bf5 [sfnt] Fix Savannah bug #41696.

Werner Lemberg 9a56764037 [bdf] Fix Savannah bug #41692.
bdflib puts data from the input stream into a buffer in chunks of
1024 bytes.  The data itself gets then parsed line by line, simply
increasing the current pointer into the buffer; if the search for
the final newline character exceeds the buffer size, more data gets
read.

However, in case the current line's end is very near to the buffer
end, and the keyword to compare with is longer than the current
line's length, an out-of-bounds read might happen since `memcmp'
doesn't stop properly at the string end.

* src/bdf/bdflib.c: s/ft_memcmp/ft_strncmp/ to make comparisons
stop at string ends.
2014-02-26 13:08:07 +01:00

`windows'.

Werner Lemberg d87f9a65a8 Fix compilation with MinGW.
Right now, compilation out of the box with latest MinGW is broken
due to bugs in header files of mingwrt 4.0.3 in strict ANSI mode,
cf.

Werner Lemberg a336400112 [autofit] Introduce two more slots for standard characters.

Werner Lemberg 0d97744d81 [autofit] Fix Indic scripts.
Split the single, incorrect Indic entry into separate scripts so
that the covered ranges are the same: Bengali, Devanagari, Gujarati,
Gurmukhi, Kannada, Limbu, Malayalam, Oriya, Sinhala, Sundanese,
Syloti Nagri, Tamil, Telugu, and Tibetan.  At the same time, remove
entries for Meetai Mayak and Sharada – the Unicode ranges were
incorrect (and nobody has complained about that), fonts are scarce
for those scripts, and the Indic auto-hinter support is rudimentary
anyways.

* src/autofit/afscript.h: Updated, using AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK.

* src/autofit/afstyles.h (STYLE_DEFAULT_INDIC): New auxiliary macro.
Use it, together with AF_CONFIG_OPTION_INDIC and
AF_CONFIG_OPTION_CJK, to update.

* src/autofit/afranges.c [AF_CONFIG_OPTION_INDIC]: Updated.
[!AF_CONFIG_OPTION_INDIC, !AF_CONFIG_OPTION_CJK]: Removed.
Sort entries by tags.

Werner Lemberg 1b5bc89754 [autofit] Fix handling of default coverages.
With this commit, the implementation of coverage handling is
completed.

* src/autofit/hbshim.c (af_get_coverage): Exit early if nothing to
do.
Reject coverages which don't contain appropriate glyphs for blue
zones.

Werner Lemberg a42f918434 [autofit] Fix handling of default coverages.

default script, and finally the other default coverages.

auxiliary macros; use them to define styles for Cyrillic, Greek, and
Latin.

* src/autofit/afcover.h: Remove coverage for oldstyle figures.
Since those digits are used in combination with ordinary letters, it
makes no sense to handle them separately.

* src/autofit/afglobal.c (af_face_globals_get_metrics): Don't limit
`options' parameter to 4 bits.
