with the current Perl.
-B<-I> <path1:path2>
+B<-I> E<lt>path1:path2E<gt>

Keep in mind, you can always supply B</my/own/path/ModuleName.a>

Additional linker arguments to be considered.

-specifed by the B<-I> option.
+specified by the B<-I> option.
In addition, when ModuleName.a is found, additional linker arguments
are picked up from the B<extralibs.ld> file in the same directory.
perl -MExtUtils::Embed -e ldopts -- -std Socket
-
+
This will do the same as the above example, along with printing additional arguments for linking with the B<Socket> extension.
For including perl header files this function simply prints:
- -I $Config{archlib}/CORE
+ -I$Config{archlibexp}/CORE
So, rather than having to say:
- perl -MConfig -e 'print "-I $Config{archlib}/CORE"'
+ perl -MConfig -e 'print "-I$Config{archlibexp}/CORE"'
Just say:
B<xsinit()> uses the xsi_* functions to generate most of it's code.
