I built a CMake 2.4.2 for Cygwin from sources. I used the "Unix
linefeed" download, cmake-2.4.2.tar.gz. I used an earlier Cygwin CMake
package to build it. Now I am using this Cygwin CCMake 2.4.2 to
generate my Chicken build. When it comes time to link a .dll, it fails
with:
Linking C shared library libchicken.dll
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld:
cannot find
-ldl
collect2: ld returned 1 exit status
make[2]: *** [libchicken.dll] Error 1
make[1]: *** [CMakeFiles/libchicken.dir/all] Error 2
make: *** [all] Error 2
I Googled and found a post on cygwin.org that says this is a Linuxism.
Cygwin is not supposed to have any -ldl. In fact, neither are some
other Unixes, like FreeBSD for instance. The following 2 posts clarify
the issue:

http://www.cygwin.com/ml/cygwin/2003-07/msg00732.html
Is there a way I can build CMake 2.4.2 on Cygwin to get correct
behavior, like some kind of self-recompile, or is it a deeper bug than
that? In any event, I think having a correct 2.4.2 package in the
Cygwin distro is adviseable.
Cheers,
Brandon Van Every
