Re: Stream Raw converter and un/signed integrer

[Dirk Zimoch <dirk.zimoch@psi.ch>]

Hi,

StreamDevice does not come with its own configure directory. If you have ever 
used makeBaseApp, you should already have a configure directory. You will most 
probably have customized your RELEASE file. StreamDevice does not try to 
overwrite your configure settings.

Just unpack the tar file in parallel to the configure directory makeBaseApp 
created for you.

From the StreamDevice Documentation, chapter "Setup":

> Up to release R3.14.8.2, a fix in EPICS base is required to build StreamDevice on Windows (not cygwin). In src/iocsh/iocsh.h, add the following line and rebuild base.

Is there also a problem with the missing  iocshCmd for other OS than Windows? In 
that case I will modify the documentation.
