This is on cygwin on Windows XP, with a pristine trunk HEAD. After a successful
$ ./configure --enable-shared
make fails when compiling socket. The error message is as follows:
compiling socket
make: *** [mkmain.sh] Error 1

The mkmf.log file found in ext/socket is attached.

Regards, Martin.

Attaching a file apparently failed (see Bug #1779).
I'm including the last few lines of the abovementioned mkmf.log file here:

Worked for me here with cygwin-1.7.0-51 on XP, gcc4-core-4.3.2-2, ruby-1.8.7-p72-2, and compiling ruby-1.9.2-r24017 .

Looks like you have ruby 1.9.x installed in /cygdrive/c/ruby or c:\ruby, and that is the ruby that comes first in PATH. I suspect that it is a non-cygwin native win32 ruby, which failed to handle a cygwin-style path.

from ./ext/extmk.rb:154:in `load'
conf = ["#{$srcdir}/makefile.rb", "#{$srcdir}/extconf.rb"].find {|f| File.exist?(f)}
......
if conf
load $0 = conf
else
......

I suspect $srcdir had some cygwin-style path in it.

By the way, --enable-shared is the default in cygwin and is probably unnecessary. configure.in says:

case "$target_os" in
when(cygwin*|mingw*)
.....
case "$target_os" in
when(mingw*)
......
esac
: ${enable_shared=yes}
;;
when(aix*)

We haven't observed this problem for a long time anymore, so I think this bug should be closed.
