- This document contains instructions on how to build the FreeType
- library on Unix systems. This also works for emulations like Cygwin
- or MSys on Win32:
-
-
- 1. Ensure that you are using GNU Make
- -------------------------------------
-
- The FreeType build system _exclusively_ works with GNU Make. You
- will not be able to compile the library with the instructions
- below using any other alternative (including BSD Make).
-
- Check that you have GNU make by running the command:
-
- make -v
-
- This should dump some text that begins with:
-
- GNU Make <version number>
- Copyright (C) <year> Free Software Foundation Inc.
-
- Note that version 3.81 or higher is *required* or the build will
- fail.
-
- It is also fine to have GNU Make under another name (e.g. 'gmake')
- if you use the MAKE variable as described below.
-
- As a special exception, 'makepp' can also be used to build
- FreeType 2. See the file docs/MAKEPP for details.
-
- For builds with `cmake' please check file `CMakeLists.txt'; this
- is a contributed file not directly supported by the FreeType team.
-
-
- 2. Regenerate the configure script if needed
- --------------------------------------------
-
- This only applies if you are building a git snapshot or checkout,
- *not* if you grabbed the sources of an official release.
-
- You need to invoke the `autogen.sh' script in the top-level
- directory in order to create the `configure' script for your
- platform. Normally, this simply means typing:
-
- sh autogen.sh
-
- In case of problems, you may need to install or upgrade Automake,
- Autoconf or Libtool. See `README.git' in the top-level directory
- for more information.
-
-
- 3. Build and install the library
- --------------------------------
-
- Say
-
- ./configure --help
-
- to see the list of possible configuration options and important
- environment variables. The ./configure script will detect some
- prerequisite system libraries (libpng, brotli, etc.) if their
- headers are available at the default locations.
-
- The following should work on all Unix systems where the `make'
- command invokes GNU Make:
-
- ./configure [options]
- make
- make install (as root)
-
- The default installation path is `/usr/local'. It can be changed
- with the `--prefix=<path>' option. Example:
-
- ./configure --prefix=/usr
-
- When using a different command to invoke GNU Make, use the MAKE
- variable. For example, if `gmake' is the command to use on your
- system, do something like:
-
- MAKE=gmake ./configure [options]
- gmake
- gmake install (as root)
-
- If this still doesn't work, there must be a problem with your
- system (e.g., you are using a very old version of GNU Make).
-
- For library identification, FreeType's `configure' script uses the
- `pkg-config' interface: Assuming it needs library `foo', it calls
- the `pkg-config' program to find information on library `foo',
- which in turn looks for a `foo.pc' file installed at the system.
- Some platforms, however, don't come with `pkg-support'; you then
- have to use environment variables as described by `configure
- --help'. Example:
-
- LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \
- LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \
- configure ...
-
- It is possible to compile FreeType in a different directory.
- Assuming the FreeType source files in directory `/src/freetype' a
- compilation in directory `foo' works as follows:
-
- cd foo
- /src/freetype/configure [options]
- make
- make install
-
-
- 3.1 Interdependency with HarfBuzz
- .................................
-
- Note that there is a chicken-and-egg problem currently since the
- HarfBuzz library (used by the auto-hinter to improve support of
- OpenType fonts) depends on FreeType, which can be solved as
- follows in case HarfBuzz is not yet installed on your system.
-
- 1. Call FreeType's `configure' script with option
- `--without-harfbuzz', then compile and install FreeType.
-
- 2. Compile and install HarfBuzz.
-
- 3. Call FreeType's `configure' script without option
- `--without-harfbuzz' (after executing `make distclean'), then
- compile and install FreeType again.
