17 | <title>Installation of Coreutils</title>
|

18 |
|
---|
19 | <para>Normally the functionality of <userinput>uname</userinput> is somewhat
|
---|
20 | broken, in that the <userinput>-p</userinput> switch always returns "unknown".
|
---|
21 | The following patch fixes this behaviour for Intel architectures:</para>
|
---|
22 |
|
---|
23 | <screen><userinput>patch -Np1 -i ../&coreutils-uname-patch;</userinput></screen>
|
---|
24 |
|
---|
25 | <para>We do not want Coreutils to install its version of the
|
---|
26 | <userinput>hostname</userinput> program, because it is inferior to the version
|
---|
27 | provided by Net-tools. Prevent its installation by applying a patch:</para>
|
---|
28 |
|
---|
29 | <screen><userinput>patch -Np1 -i ../&coreutils-hostname-patch;</userinput></screen>
|
---|
30 |
|
---|
31 | <para>Now prepare Coreutils for compilation:</para>
|
---|
32 |
|
---|
33 | <screen><userinput>./configure --prefix=/usr</userinput></screen>
|
---|
34 |
|
---|
35 | <para>Compile the package:</para>
|
---|
36 |
|
---|
37 | <screen><userinput>make</userinput></screen>
|
---|
38 |
|
---|
39 | <para>The <userinput>su</userinput> program from Coreutils wasn't installed in
|
---|
40 | Chapter 5 because it needed <emphasis>root</emphasis> privilege to do so. We're
|
---|
41 | going to need it in a few moments for the test suite. Therefore we work around
|
---|
42 | the problem by installing it now:</para>
|
---|
43 |
|
---|
44 | <screen><userinput>make install-root</userinput></screen>
|
---|
45 |
|
---|
46 | <para>This package has a test suite available which can perform a number of
|
---|
47 | checks to ensure it built correctly. However, this particular test suite
|
---|
48 | makes some assumptions with regards to the presence of non-root users and
|
---|
49 | groups that don't apply this early into the LFS build. We therefore create
|
---|
50 | a dummy system user and two dummy groups to allow the tests to run
|
---|
51 | properly. Should you choose not to run the test suite, skip down to
|
---|
52 | "Install the package". The following commands will prepare us for the test
|
---|
53 | suite. Create two dummy groups and a dummy user name:</para>
|
---|
54 |
|
---|
55 | <screen><userinput>echo "dummy1:x:1000" >> /etc/group
|
---|
56 | echo "dummy2:x:1001:dummy" >> /etc/group
|
---|
57 | echo "dummy:x:1000:1000:::/bin/bash" >> /etc/passwd</userinput></screen>
|
---|
58 |
|
---|
59 | <para>Some tests are meant to run as <emphasis>root</emphasis>:</para>
|
---|
60 |
|
---|
61 | <screen><userinput>make check-root</userinput></screen>
|
---|
62 |
|
---|
63 | <para>The remainder of the tests are run as the <emphasis>dummy</emphasis>
|
---|
64 | user:</para>
|
---|
65 |
|
---|
66 | <screen><userinput>su dummy -c "make RUN_EXPENSIVE_TESTS=yes check"</userinput></screen>
|
---|
67 |
|
---|
68 | <para>Remove the dummy groups and user name:</para>
|
---|
69 |
|
---|
70 | <screen><userinput>sed -i.bak '/dummy/d' /etc/passwd /etc/group</userinput></screen>
|
---|
71 |
|
---|
72 | <para>Install the package:</para>

73 |
|
---|
74 | <screen><userinput>make install</userinput></screen>
|
---|
75 |
|
---|
76 | <para>And move some programs to their proper locations:</para>
|
---|
77 |
|
---|
78 | <screen><userinput>mv /usr/bin/{basename,cat,chgrp,chmod,chown,cp,dd,df} /bin
|
---|
79 | mv /usr/bin/{date,echo,false,head,install,ln,ls} /bin

80 | mv /usr/bin/{mkdir,mknod,mv,pwd,rm,rmdir,sync} /bin

81 | mv /usr/bin/{sleep,stty,su,test,touch,true,uname} /bin
|
---|
82 | mv /usr/bin/chroot /usr/sbin</userinput></screen>
|
---|
83 |
|
---|
84 | <para>We'll be using the <filename>kill</filename> program from the Procps
|
---|
85 | package (installed as <filename>/bin/kill</filename> later in the chapter).
|
---|
86 | Remove the one installed by Coreutils:</para>
|

87 |
|
---|
88 | <screen><userinput>rm /usr/bin/kill</userinput></screen>
|
---|
89 |
|
---|
90 | <para>Finally, create a few necessary symlinks:</para>
