- 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 3.80 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
- --------------------------------
- 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).
- 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.
