# A warning, promoted to an error by libxcrypt's own -Werror. Our gcc is 16.2.1;
|
||
|
|
# libxcrypt 4.5.2 was released against considerably older ones, and this
|
||
|
|
# diagnostic is not about the port -- the same code warns the same way on x86_64
|
||
|
|
# with the same compiler.
|

# --disable-werror is libxcrypt's own switch. Patching the source would mean
|
||
|
|
# carrying a diff against upstream C for a const-correctness nit in an
|
||
|
|
# implementation of a Russian hash standard that nothing here uses; declining to
|
||
|
|
# treat warnings as errors is what a distribution does when its compiler is
|
||
|
|
# ahead of a release.

#
|

|
# BOTH CONFIGURE CALLS. libxcrypt is built twice -- once normally and once for
|
||
|
|
# the obsolete-API compat library -- and fixing only the first leaves the second
|
||
|
|
# failing identically, which reads as if the flag had no effect.
