<listitem>
|
|
<para>This option specify the result of a check for the
|
|
<function>strcasecmp</function>. The check requires running a
|
|
compiled C program, and this is impossible during
|
|
cross-compilation because in general a cross-compiled program
|
|
cannot run on the host distro. Normally for such a check the
|
|
<command>configure</command> script would use a fall-back value
|
|
for cross-compilation, but the fall-back value for this check is
|
|
absent and the <command>configure</command> script would have no
|
|
value to use and error out. The upstream has already fixed the
|
|
issue, but to apply the fix we'd need to run
|
|
<command>autoconf</command> that the host distro may lack. So
|
|
we just specify the check result (<literal>y</literal> as we know
|
|
the <function>strcasecmp</function> function in
|
|
Glibc-&glibc-version; works fine) instead, then
|
|
<command>configure</command> will just use the specified value and
|
|
skip the check.</para>
