2. I don't understand what it means, because I use cl compiler. cc -o perl-interp perl-interp.c `perl -MExtUtils::Embed -e ccopts -e ldopts`

The command-line arguments (as you call them ) are actually backticks and expand out into the needed includes and libs needed by your Perl version. On linux/unix style systems, it is done all the time, look at gtk's pkg-config system.

Anyways, on my system, the bacticks expand out to

-Wl,-E  -L/usr/local/lib /usr/lib/perl5/5.8.8/i686-linux-thread-multi/
+auto/DynaLoader/DynaLoader.a -L/usr/lib/perl5/5.8.8/i686-linux-thread
+-multi/CORE -lperl -lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lpthrea
+d -lc
 -D_REENTRANT -D_GNU_SOURCE -DTHREADS_HAVE_PIDS -fno-strict-aliasing -
+pipe -Wdeclaration-after-statement -I/usr/local/include -D_LARGEFILE_
+SOURCE -D_FILE_OFFSET_BITS=64  -I/usr/lib/perl5/5.8.8/i686-linux-thre
+ad-multi/CORE

As you can see, using the backticks, is far easier than manually trying to find all those system-specific file locations.

And sorry, I don't use windows, so I'm as lost as you as far as win32 goes.
