Hi Steve,

We compiled mca on Solaris and created a shareable library. I've not yet compiled on Linux as nobody has requested it. I don't think the compiled mca library is used much. In my current project (SPEAR), we use Solaris matlab for RF only. All other matlab apps are run on Windoze (and use mca). And for RF, the Solaris compiled matlab executables are currently using the "unix" command with "caget" and "caput" for get/put PVs. They haven't been converted to mca yet, if ever. One worry I have about mca is the hardcoded 1 second timeout on all CA calls (perhaps this is changed in a newer version). This may be a problem for some of the RF matlab apps. I know a user in the NLCTA project was having a problem with the 1 second timeout in mca when she was forced to go through a slow gateway process.

No. The very very little bit of testing I did on Solaris didn't show this problem.
