SOFTWARE REQUIREMENTS

3
   Compiling uClibc requires Linux kernel header files.  uClibc will
4
   be compiled to match the interfaces available in the provided
5
   version of the Linux kernel headers.  Linux kernel version 2.0,
6
   version 2.2, version 2.4 and version 2.6 are known to work.  Other
7
   kernel versions may work but havn't been tested.  Its also helpful
8
   to have a working version of GNU binutils, and GNU gcc -- using
9
   excessively old versions of these packages can cause very strange
10
   errors that are difficult to find and fix.
11
 
12
 
13
CONFIGURING uClibc:
14
 
15
 - Use must have a valid configuration file to compile uClibc.  Do not
16
    skip this step.  New configuration options are added in each
17
    release, and odd configuration options are sometimes removed.
18
    To configure uClibc, you can run:
19
 
20
            make menuconfig
21
    or
22
            make config
23
 
24
    If you have an existing .config file, you can update this file
25
    using the
26
 
27
            make oldconfig
28
 
29
    command, which will only ask you about new configuration options.
30
 
31
    Available configuration commands are:
32
        "make config"       Text based configuration, no menus or colors.
33
        "make menuconfig"   Text based color menus, radiolists & dialogs.
34
        "make oldconfig"    Default all questions based on the contents of
35
                             your existing ./.config file.
36
        "make defconfig"    Use defaults for all options.
37
        "make randconfig"   Use random values for all options.
38
        "make allyesconfig" Set all values to "yes" for all options.
39
        "make allnoconfig"  Set all values to "no" for all options.

COMPILING uClibc:
45
 
46
 - uClibc does not have proper dependancy checking (yet) so if you
47
    change your uClibc configuration, you must current rebuild the
48
    entire library, by first running
49
 
50
            make clean
51
 
52
 - Once you have a valid configuration file, just run
53
 
54
            make
55
 
56
    to compile uClibc.  or if you are cross compiling, you would
57
    instead run something like:
58
 
59
            make CROSS=arm-linux-
60
 
61
 
62
 
63
INSTALLING the uClibc development environment:
64
 
65
 - As root, if necessary, run something like:
66
 
67
        make PREFIX= install
68
 
69
    This will install the uClibc runtime and development system (i.e.
70
    all the header files, libraries, etc) into the directories defined
71
    within your .config file.
72
 
73
 
74
USING uClibc:
75
 
76
 - To compile programs with uClibc you will need a complete toolchain
77
    (i.e. binutils, gcc, and uClibc) that was built expressly for use
78
    with uClibc.
79
 
80
 - Native and cross compiling toolchains, as well as makefiles for creating
81
   uClibc toolchains, are available from the uClibc website.  You may want
82
   to check out "buildroot", which is available from the uClibc download area,
83
   which provides examples of how to build your own uClibc based system.
