Have you built ACE for Cygwin? You will probably need to regenerate your make files; if they are testing for *.so, then they are still the Linux versions, and it's a bad idea to just disable those checks! The instructions for building ACE on Cygwin (http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/ACE-INSTALL.html#cy gwin) are a little out of date, but they might work for you. Note the ACE build on Cygwin is experimental. > --- "Larry Hall (Cygwin)" > <[EMAIL PROTECTED]> wrote: > >> Longyu Mei wrote: >>> Great!
