ORBit2 under cygwin

[Bowie Owens <bowie owens csiro au>]

Hi,

I am trying to get ORBit2 2.7.2 to build under cygwin using libIDL 0.8.0 
(and a patched glib 2.2.0). I have gotten through the compilation 
(having adjusted a few #include's within linc2) now I am stuck at the 
linking. ORBit dies with a heap of unresolved reference errors to 
functions within libIDL not long after the following:

rm -fr  .libs/libORBit-imodule-2.dll.a

When I built libIDL it seems like it was unable to create a shared 
library version:

extracting exported symbol list from `cygiconv-2.dll'
test -f .libs/impgen.c || \
     sed -e "/^# \/\* impgen\.c starts here \*\//,/^# \/\* impgen.c 
ends here \
*\// { s/^# //;s/^# *$//; p; }" -e d < ./libtool > .libs/impgen.c
     test -f .libs/impgen.exe || (cd .libs && \
     if test "x" != "x" ; then  -o impgen impgen.c ; \
     else gcc -o impgen impgen.c ; fi)

(cd .libs && rm -f libIDL-2.la && ln -s ../libIDL-2.la libIDL-2.la)

Has someone already done this? Is there any way to work out what is 
preventing libIDL from being built as a shared library and fixing it? Or 
can ORBit be convinced to use the static library? Any thoughts would be 
most appreciated.
