This document contains instructions on how to build the FreeType
|
|
|
2 |
library on Unix systems. This also works for emulations like Cygwin
|
|
|
3 |
or MSys on Win32:
|
|
|
4 |
|
|
|
5 |
|
|
|

1. Ensure that you are using GNU Make
|
|
|
7 |
-------------------------------------
|
|
|
8 |
|
|
|
9 |
The FreeType build system _exclusively_ works with GNU Make. You
|
|
|
10 |
will not be able to compile the library with the instructions
|
|
|
11 |
below using any other alternative (including BSD Make).
|
|
|
12 |
|
|
|
13 |
Check that you have GNU make by running the command:
|
|
|
14 |
|
|
|
15 |
make -v
|
|
|
16 |
|
|
|
17 |
This should dump some text that begins with:
|
|
|
18 |
|
|
|
19 |
GNU Make <version number>
|
|
|
20 |
Copyright (C) <year> Free Software Foundation Inc.
|
|
|
21 |
|
|
|
22 |
Note that version 3.80 or higher is *required* or the build will
|
|
|
23 |
fail.
|
|
|
24 |
|
|
|
25 |
It is also fine to have GNU Make under another name (e.g. 'gmake')
|
|
|
26 |
if you use the GNUMAKE variable as described below.
|
|
|
27 |
|
|
|
28 |
As a special exception, 'makepp' can also be used to build
|
|
|
29 |
FreeType 2. See the file docs/MAKEPP for details.
|
|
|
30 |
|
|
|
31 |
|
|
|
32 |
2. Regenerate the configure script if needed
|
|
|
33 |
--------------------------------------------
|
|
|
34 |
|
|
|
35 |
This only applies if you are building a git snapshot or checkout,
|
|
|
36 |
*not* if you grabbed the sources of an official release.
|
|
|
37 |
|
|
|
38 |
You need to invoke the `autogen.sh' script in the top-level
|
|
|
39 |
directory in order to create the `configure' script for your
|
|
|
40 |
platform. Normally, this simply means typing:
|
|
|
41 |
|
|
|
42 |
sh autogen.sh
|
|
|
43 |
|
|
|
44 |
In case of problems, you may need to install or upgrade Automake,
|
|
|
45 |
Autoconf or Libtool. See README.git in the top-level directory
|
|
|
46 |
for more information.
|
|
|
47 |
|
|
|
48 |
|
|
|
49 |
3. Build and install the library
|
|
|
50 |
--------------------------------
|
|
|
51 |
|
|
|
52 |
The following should work on all Unix systems where the `make'
|
|
|
53 |
command invokes GNU Make:
|
|
|
54 |
|
|
|
55 |
./configure [options]
|
|
|
56 |
make
|
|
|
57 |
make install (as root)
|
|
|
58 |
|
|
|
59 |
The default installation path is `/usr/local'. It can be changed
|
|
|
60 |
with the `--prefix=<path>' option. Example:
|
|
|
61 |
|
|
|
62 |
./configure --prefix=/usr
|
|
|
63 |
|
|
|
64 |
When using a different command to invoke GNU Make, use the GNUMAKE
|
|
|
65 |
variable. For example, if `gmake' is the command to use on your
|
|
|
66 |
system, do something like:
|
|
|
67 |
|
|
|
68 |
GNUMAKE=gmake ./configure [options]
|
|
|
69 |
gmake
|
|
|
70 |
gmake install (as root)
|
|
|
71 |
|
|
|
72 |
If this still doesn't work, there must be a problem with your
|
|
|
73 |
system (e.g., you are using a very old version of GNU Make).
|
|
|
74 |
|
|
|
75 |
It is possible to compile FreeType in a different directory.
|
|
|
76 |
Assuming the FreeType source files in directory `/src/freetype' a
|
|
|
77 |
compilation in directory `foo' works as follows:
|
|
|
78 |
|
|
|
79 |
cd foo
|
|
|
80 |
/src/freetype/configure [options]
|
|
|
81 |
make
|
|
|
82 |
make install
|
|
|
83 |
|
|
|
84 |
