While executing "make install" under MacOS 10.4.7, you may encounter errors about "dio". It is the
problem of "Makefile". I did some change to it and attach the diff file here. |

Most likely you changed the maximal event size in midas.h, but you did not re-compile [B]all[/B] programs. The maximal event size goes into the size of
the shared memory buffer, so all participating programs have to have the same setting, especially the mserver program. So do the following:

people might get annoyed to receive too many emails from you. Think what you want to write and then post once.
