[96e0ac7] | 6 | <para>The Glibc build system is very well self-contained and will install
|
---|
| 7 | perfectly, even though our compiler specs file and linker scripts are still
|
---|
[148bb04] | 8 | pointing at <filename>/tools</filename>. We cannot adjust the specs and
|
---|
[96e0ac7] | 9 | ldscripts before the Glibc install, because the Glibc autoconf tests would then
|
---|
| 10 | give bogus results and thus defeat our goal of achieving a clean build.</para>

[d3d229f] | 74 | <para>An alternative to running the previous command is to install only those

[96e0ac7] | 75 | locales which you need or want. This can be achieved using the

| 76 | <userinput>localedef</userinput> command. Information on this can be found in

| 77 | the <filename>INSTALL</filename> file in the

[c825bdc] | 78 | <filename>glibc-&glibc-version;</filename> tree. However, there are a number

| 79 | of locales that are essential for the tests of future packages to pass
|
---|
| 80 | correctly. The following instructions, in place of the install-locales
