| 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. | |
| 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. | |
