- fixing apinames.c, adding support for Watcom and Borland compilers
- adding generation of exported symbols list to the build system, including the Unix one !!
sorry Werner, I have no time to document this in ChangeLog at the moment
(CFLAGS), builds/compiler/gcc.mk (CFLAGS): Remove
-fno-strict-aliasing.
Say you have `(Foo*)x' and want to assign, pass, or return it as
`(Bar*)'. If you simply say `x' or `(Bar*)x', then the C compiler
would warn you that type casting incompatible pointer types breaks
strict-aliasing. The solution is to cast to `(void*)' instead which
is the generic pointer type, so the compiler knows that it should
make no strict-aliasing assumption on `x'. But the problem with
`(void*)x' is that seems like in C++, unlike C, `void*' is not a
generic pointer type and assigning `void*' to `Bar*' without a cast
causes an error. The solution is to cast to `Bar*' too, with
`(Bar*)(void*)x' as the result -- this is what the patch does.
* include/freetype/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP),
include/freetype/cache/ftcmru.h (FTC_MRULIST_LOOKUP_CMP): Remove
cast on lvalue, use a temporary pointer instead.
Cast temporarily to (void*) to not break strict aliasing.
* include/freetype/internal/ftmemory.h (FT_MEM_ALLOC,
FT_MEM_REALLOC, FT_MEM_QALLOC, FT_MEM_QREALLOC, FT_MEM_FREE),
src/base/ftglyph.c (FT_Glyph_To_Bitmap): Cast temporarily to (void*)
to not break strict aliasing.
* src/base/ftinit.c (FT_USE_MODULE): Fix wrong type information.
* builds/unix/configure.ac (XX_CFLAGS): Remove -fno-strict-aliasing.
* src/sfnt/rules.mk (SFNT_DRV_SRC): Don't include ttsbit0.c --
it is currently loaded from ttsbit.c.
Other formatting.
* builds/dos/dos-emx.mk, builds/compiler/emx.mk: New files for
EMX gcc compiler.
* builds/dos/detect.mk: Add target `emx'.
* builds/compiler/watcom.mk (LINK_LIBRARY): GNU Make for DOS doesn't
like a trailing semicolon; add a dummy command.
. In all makefiles `/' is used as the path separator. The
conversion to the real path separators is done as late as
possible using $(subst ...).
. $(HOSTSEP) no longer exists. Now, $(SEP) gives the path separator
for the operating system, and the new $(COMPILER_SEP) the path
separator for the compiler tools.
. $(BUILD) has been renamed to $(BUILD_DIR). In general, all
directory variables end with `_DIR'. The variants ending in `_'
(like `BASE_' have been removed).
The following ChangeLog entries only describe changes which are
not related to the redesign.
* builds/beos/beos-def.mk (BUILD_DIR): Fix typo.
* builds/compiler/watcom.mk (LINK_LIBRARY): Fix linker call to avoid
overlong arguments as suggested by J. Ali Harlow
<ali@avrc.city.ac.uk>.
* builds/dos/dos-wat.mk: New file.
* builds/freetype.mk (FREETYPE_H): Include header files from the
`devel' subdirectory.
* builds/os2/os2-dev.mk, builds/unix/unixddef.mk,
builds/unix/unixddef.mk, builds/win32/w32-bccd.mk,
builds/win32/w32-dev.mk (BUILD_DIR): Fix path.
* builds/unix/configure.ac, builds/unic/configure: Updated.
* builds/unix/unix-def.in (DISTCLEAN): Add `freetype2.pc'.
* devel/ftoption.h: Updated.
the structure of similar makefiles.
* builds/dos/*.mk: Ditto.
* builds/ansi/*.mk: Ditto.
* builds/win32/win32-def.mk (BUILD): Fix typo.
* builds/compiler/*.mk (CLEAN_LIBRARY): Don't use NO_OUTPUT.
This is already used in the link_*.mk files.
* src/*/Jamfile: Slight changes to make files more cryptic.
to use direct definitions. This is the only way to do these things
in a portable way :-( The rest of the code should follow shortly
though everything compiles now.
* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.
* builds/win32/detect.mk: Added support for the Intel C/C++
compiler, as well as _preliminary_ (read: doesn't work!) support for
Watcom. Also added a new setup target. Type "make setup list" for
a list of supported command-line compilers on Win32.
* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
conditionals are off.
include/freetype/internal/internal.h: fixed header inclusion macros
to use direct definitions. This is the only way to do these things
in a portable way :-( The rest of the code should follow shortly
though everything compiles now..
* builds/compiler/intelc.mk, builds/compiler/watcom.mk,
builds/win32/detect.mk: added support for the Intel C/C++ compiler,
as well as _preliminary_ (read: doesn't work !!) support for Watcom.
Also added a new setup target. Type "make setup list" for a list
of supported command-line compilers on Win32..
default..
- created "builds/devel" to hold developer builds options
for both Win32 and Unix
- fixed a bug in the winfonts driver, where the glyph image format
wasn't set correctly..
* builds/compiler/bcc-dev.mk, builds/compiler/visualage.mk,
builds/compiler/bcc.mk, builds/win32/w32-bcc.mk,
builds/win32/w32-bccd.mk: Revised.
* include/freetype/config/ftbuild.h,
include/freetype/internal/internal.h: Revised.
* include/freetype/ftimage.h: Updated to new header inclusion scheme.
* builds/toplevel.mk (.PHONY): Adding `distclean'.
* builds/unix/detect.mk (.PHONY): Adding `devel', `unix', `lcc',
`setup'.
* INSTALL: Slightly updated the quick starter documentation to
include IDE compilation, prevent against BSD Make, and specify "make
setup" instead of a single "make" for build configuration.
* include/config/ftbuild.h, include/internal/internal.h: Added new
configuration files used to determine the location of all public,
configuration, and internal header files for FreeType 2. Modified
all headers under "include/freetype" to reflect this change. Note
that we still need to change the library source files themselves
though.
builds/win32/detect.mk: Added new files to support compilation with
the free Borland C++ command-line compiler. Modified the detection
rules to recognize the new "bcc32" target in "make setup bcc32".
src/truetype/ttobjs.c, src/truetype/ttgload.c,
src/truetype/ttinterp.c: Fixed a few comparisons that Borland C++
didn't really like. Basically, this compiler complains when FT_UInt
is compared to FT_UShort (apparently, it promotes `UShort' to `Int'
in these cases).
in the "builds" directory
- modified a few files because BCC32 didn't like certain comparisons
(UInt compared with a UShort, apparently the UShort is promoted to
an Int)
- updated the INSTALL file to include IDE compilation, prevent against
BSD Make, and clarify the use of "make setup" (instead of "make")
for build configuration
- reworked slightly the cache manager to better
differentiate between the abstract class in "ftcglyph.h"
and the FT_Glyph sub-class in "ftcimage.h", and
slightly reduced the size of FTC_GlyphNodeRec, saving
8 bytes on a 32-bit system. Yes, I'm crazy ;-)
- added build files to compile with LCC on Unix too
(compile speeds _are_ insane with it). There is unfortunately
a bug in the version I'm using (LCC 4.1) that prevents it
to compile FT_MulTo64 correctly (in src/base/ftcalc.c)
the generated assembly is incorrect, I don't know what
to do ?? the build files are ok, though..
you should invoke "make setup lcc" to select them..
