Has anybody converted StripToll to build with EPICS release 3.14 ?
Without history feature it can be built with 3.14.7 on SL4 without
problems. But when I try to build it with Channel Archiver (which
was built successfully,

thanks Gasper Pajor) ...

It can not find osiTime.h (just because it does not exist for
3.14). Then it complains:
../StripHistoryLANLmodif.cc:144: no matching function for call to `
  ChannelIterator::getValueAfterTime(const osiTime&, ValueIterator&)'
and other.
It would be nice to get updated StripTool and not to go through all
these hedges.

There is currently no support for the striptool history module
interfacing with the R3.14 ChannelArchiver.
Technical reasons include:

- Requests to the data server should be handled asynchronously,

because they can take time.

The striptool history module looks like it supports async operation.

StripHistory.h claims that StripHistory_fetch() is allowed to
return "..PENDING"

and invoke a callback when done.

However, the provided callback is 0, and "..PENDING" isn't really
supported.

- Striptool has no defined interface where a history module could

be configured. For the R3.14 archiver, you have to configure the
data server

URL and the archive key.

There are versions of Striptool with #ifdefs that create

an archive source configuration dialog specific to e.g. a DESY
data server,

but I don't want to hack and possibly break Striptool

to sneak in support for the R3.14 archive data server.
So far, nobody has had time to fix this.
