The current (cvs) version of MIDAS should build on Mac OS X right out of the
box- I fixed all the problems you report back in February(?)- see the macosx
thread in this forum. A few weeks ago I verified that it still compiles on Mac
OS 10.3.4. The Mac OS port received minimal testing- I checked that "odbedit"
and "mhttpd" run, that's about it. K.O.
