2 SPECIAL NOTE FOR UNIX USERS |
|
3 =========================== |
|
4 |
|
5 If you are installing this release of FreeType on a system that |
|
6 already uses release 2.0.5 (or even an older version), you have to |
|
7 perform a few special steps to ensure that everything goes well. |
|
8 |
|
9 |
|
10 1. Enable the TrueType bytecode hinter if you need it |
|
11 ----------------------------------------------------- |
|
12 |
|
13 See the instructions in the file `TRUETYPE' of this directory. |
|
14 |
|
15 Note that FreeType supports TrueType fonts without the bytecode |
|
16 interpreter through its auto-hinter, which now generates relatively |
|
17 good results with most fonts. |
|
18 |
|
19 |
|
20 2. Determine the correct installation path |
|
21 ------------------------------------------ |
|
22 |
|
23 By default, the configure script installs the library in |
|
24 `/usr/local'. However, many Unix distributions now install the |
|
25 library in `/usr', since FreeType is becoming a critical system |
|
26 component. |
|
27 |
|
28 If FreeType is already installed on your system, type |
|
29 |
|
30 freetype-config --prefix |
|
31 |
|
32 on the command line. This should return the installation path |
|
33 (e.g., `/usr' or `/usr/local'). To avoid problems of parallel |
|
34 FreeType versions, use this path for the --prefix option of the |
|
35 configure script. |
|
36 |
|
37 Otherwise, simply use `/usr' (or whatever you think is adequate for |
|
38 your installation). |
|
39 |
|
40 |
|
41 3. Ensure that you are using GNU Make |
|
42 ------------------------------------- |
|
43 |
|
44 The FreeType build system _exclusively_ works with GNU Make (as an |
|
45 exception you can use make++ which emulates GNU Make sufficiently; |
|
46 see http://makepp.sourceforge.net). You will not be able to compile |
|
47 the library with the instructions below using any other alternative |
|
48 (including BSD Make). |
|
49 |
|
50 Trying to compile the library with a different Make tool prints a |
|
51 message like: |
|
52 |
|
53 Sorry, GNU make is required to build FreeType2. |
|
54 |
|
55 and the build process is aborted. If this happens, install GNU Make |
|
56 on your system, and use the GNUMAKE environment variable to name it. |
|
57 |
|
58 |
|
59 4. Build and install the library |
|
60 -------------------------------- |
|
61 |
|
62 The following should work on all Unix systems where the `make' |
|
63 command invokes GNU Make: |
|
64 |
|
65 ./configure --prefix=<yourprefix> |
|
66 make |
|
67 make install (as root) |
|
68 |
|
69 where `<yourprefix>' must be replaced by the prefix returned by the |
|
70 `freetype-config' command. |
|
71 |
|
72 When using a different command to invoke GNU Make, use the GNUMAKE |
|
73 variable. For example, if `gmake' is the command to use on your |
|
74 system, do something like: |
|
75 |
|
76 GNUMAKE=gmake ./configure --prefix=<yourprefix> |
|
77 gmake |
|
78 gmake install (as root) |
|
79 |
|
80 |
|
81 5. Take care of XFree86 version 4 |
|
82 --------------------------------- |
|
83 |
|
84 Certain Linux distributions install _several_ versions of FreeType |
|
85 on your system. For example, on a fresh Mandrake 8.1 system, you |
|
86 can find the following files: |
|
87 |
|
88 /usr/lib/libfreetype.so which links to |
|
89 /usr/lib/libfreetype.6.1.0.so |
|
90 |
|
91 and |
|
92 |
|
93 /usr/X11R6/lib/libfreetype.so which links to |
|
94 /usr/X11R6/lib/libfreetype.6.0.so |
|
95 |
|
96 Note that these files correspond to two distinct versions of the |
|
97 library! It seems that this surprising issue is due to the install |
|
98 scripts of recent XFree86 servers (from 4.1.0) which install their |
|
99 own (dated) version of the library in `/usr/X11R6/lib'. |
|
100 |
|
101 In certain _rare_ cases you may experience minor problems if you |
|
102 install this release of the library in `/usr' only, namely, that |
|
103 certain applications do not benefit from the bug fixes and rendering |
|
104 improvements you would expect. |
|
105 |
|
106 There are two good ways to deal with this situation: |
|
107 |
|
108 - Install the library _twice_, in `/usr' and in `/usr/X11R6' (you |
|
109 have to do that each time you install a new FreeType release |
|
110 though). |
|
111 |
|
112 - Change the link in /usr/X11R6/lib/libfreetype.so to point to |
|
113 |
|
114 /usr/lib/libfreetype.so, |
|
115 |
|
116 and get rid of |
|
117 |
|
118 /usr/X11R6/lib/libfreetype.6.0.so |
|
119 |
|
120 The FreeType Team is not responsible for this problem, so please |
|
121 contact either the XFree86 development team or your Linux |
|
122 distributor to help clear this issue in case the information given |
|
123 here doesn't help. |
