| 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. |
