Setting gl_cv_func_strcasecmp_works to "y" (or anything not ending with "yes") allows configure to complete, but with settings that prevent using the system strcasecmp function. The correct setting of the variable is "yes" (or anything ending with "yes"), which allows configure to complete, and the systemstrcasecmp function to be used Thanks to Manuel Jacob for the report.

<listitem>
|
|
<para>This option specify the result of a check for the
|
|
<function>strcasecmp</function> 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. Upstream have 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>yes</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>
