Third-party libraries
This refers to any third-party libraries that your module might require, such
as the MySQL, LDAP, and OpenSSL libraries, or any other library. Such
dependencies will require changes to the configure script which is run before
proftpd is compiled.
To have a library linkage (e.g. -lcrypto) automatically
added to the Makefile, use the special $Libraries$ keyword
near the top of your module's source file:
/* * GPL, other header information here * * DO NOT EDIT THE LINE BELOW * * $Libraries: -lcrypto $ */This covers the case where the library in question is common, and applies to all platforms.
If that library is in a non-standard location, a library path may need to
provided (i.e. the -L option). This can be done at
configure-time using the --with-libraries configure option:
./configure --with-libraries=/path/to/other/library ...Alternatively, the
LDFLAGS environment variable can be used
to pass linker information into the configure process:
LDFLAGS=linker-options ./configure ...If use of
--with-libraries or LDFLAGS is necessary
when building your module, make sure to include this requirement as part
of your module's documentation.
