Thanks. The reason in the log is:

:info:build news.c:370:36: error: incompatible function pointer types passing 'int (struct dirent *)' to parameter of type 'int (*)(const struct dirent *)' [-Wincompatible-function-pointer-types]

From the version number, this software was released in 2007, when Mac OS X 10.5 was current.

The signature of the scandir function changed to include a const in OS X 10.8. See comment:ticket:69792:3.

Previously, incompatible function pointer types was just a warning. As of Xcode 16 it is an error and needs to be fixed properly. Software wanting to use scandir should detect what the signature of that function is in the current OS and pass whatever the appropriate parameters are for that signature.

Or, the software could just use the current scandir signature and rely on legacy-support to provide compatibility with older systems; see #70702.
