Alan Coopersmith 9e345c9117 Further fix to visibility flag testing with Solaris Studio compilers.
AC_COMPILE_IFELSE only tries to compile a `*.c' to a `*.o'.  The
Solaris Studio 12.1 through 12.5 compilers see the
`-fvisibility=hidden' flag, but ignore it with a warning of:

  cc: Warning: Option -fvisibility=hidden passed to ld,
               if ld is invoked, ignored otherwise

AC_LINK_IFELSE does the compile and then tries to link the result,
at which point the Solaris linker will issue an error:

  ld: fatal: option '-fvisibility=hidden' is incompatible with
      building a dynamic executable

If we don't use AC_LINK_IFELSE to catch the error, then configure
will fail further tests which attempt to link, such as those testing
dependencies like `libbz2'.

Also, don't try adding `-fvisibility' if we have already added
`-xldscope', just use one of them, since Sun Studio 12 and earlier
compilers only issue a warning, and don't try passing through to the
linker to generate an error, so AC_LINK_IFELSE doesn't catch them.

Tested on Solaris 11.4 beta with compiler versions:

  Sun Studio 8 (Sun C 5.5)
  Sun Studio 10 (Sun C 5.7)
  Sun Studio 11 (Sun C 5.8)
  Sun Studio 12 (Sun C 5.9)
  Sun Studio 12.1 (Sun C 5.10)
  Oracle Solaris Studio 12.2 (Sun C 5.11)
  Oracle Solaris Studio 12.3 (Sun C 5.12)
  Oracle Solaris Studio 12.4 (Sun C 5.13)
  Oracle Developer Studio 12.5 (Sun C 5.14)
  Oracle Developer Studio 12.6 (Sun C 5.15)
  gcc 5.5.0
  gcc 7.3.0

and verified the libfreetype.so.6 generated by each of those
compilers exported the same set of symbols.

Werner Lemberg 7702edf793 [build] Suppress configure's `nothing to be done' message.
This is due to calling the configure script via `make' (within the

other secondary make targets that are used to only modify the
primary one, e.g., `make setup devel'.

Nikolaus Waxweiler 029721d69c Modernize CMake build.
* CMakeLists.txt, builds/cmake/FindHarfBuzz.cmake: Extensive
  modernization measures.

* .gitignore: Add build/, as that's the example directory used in
  CMakeLists.txt.

This brings up the minimum required CMake version to 2.8.12.

The installation paths follow the GNU defaults now, e.g. installing on a
64 bit host will place binaries into the lib64/ folder on e.g. Fedora.

Symbols are hidden by default (e.g. `-fvisibility=hidden' on GCC).

CMake will no longer look for a C++ compiler.

Library and .so version now match the Autotools build.

Comments in the build file and informational messages now use platform
agnostic example commands.

ftoption.h and ftconfig.h are written directly without a redundant
`-new' copy.

External dependencies are expressed as option()s and will turn up as
such in cmake-gui.

Internal: Properties such as dependencies and include directories are
now privately set on the freetype library instead of globally.

The CPack definitions have been cleaned up, the `make dist' has been
removed. Source packages generated with CPack don't contain Autotools
files and aren't used by the maintainters anyway.

On Windows, src/base/ftver.rc is compiled to decorate the library with
version and copyright information.

A pkg-config file is now generated and installed.

Ewald Hew 21bd9c2f8c [psaux] Fix Type 1 glyphs with too many stem hints.
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.

* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
hinting.
2018-01-07 16:38:54 +08:00
Werner Lemberg 3758aed760 Add `FT_Done_MM_Var'.
This is necessary in case the application's memory routines differ

that calls FreeType compiled as a DLL via the `ctypes' interface.

* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
and define.

* docs/CHANGES: Updated.

Werner Lemberg 2df73b397d [sfnt] Fix charmap type 2 iterator (#52646).
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).

Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.

for outer loop.
