Subject: Export plugin extension in config.h
X-Git-Tag: v9.21.11~23^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=be03ed6520227426d2c38616b4408cc340dca4da;p=thirdparty%2Fbind9.git

Export plugin extension in config.h

Dynamically loadable libraries all use the `.so` extension on
BIND9-supported platforms, except for macOS. Export the dynamic library
extension of the current build platform in the generated `config.h`
file, in order to let the plugin code building plugin path based on a
simple plugin name. (which then would be platform-independent)
