Subject: force link errors on OSX for unknown symbols
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a802b080f624de8ad3725e5fd86ef6931112fd16;p=thirdparty%2Ffreeradius-server.git

force link errors on OSX for unknown symbols

When linking binaries.  So that we get errors at compile time,
and not at run-time, or even later in CI tests.
