Hello All,

Has anyone used the 'pvwave' EPICS extension, i.e. CaWave.so
with PV-WAVE version 6.01?

I have two problems. 
When I build 'CaWave.so', I get:

**************************************************
Undefined			first referenced
 symbol  			    in file
_strerror                           (command line)
ld: warning: Symbol referencing errors
****************************************************

I notice that:  -u _strerror is an argument on the link line.
I tried taking this out and everything appeared to build OK.

However, under PV-WAVE, I got the following:

WAVE> .rnew CaWave
WAVE> print, caget('moveCADret.VAL')
% LINKNLOAD: Error loading sharable executable.
             Symbol: CaWaveGetCountAndType, File = CaWave.so
             Bad file
% Execution halted at CALL_CAWAVE <CaWave.pro(  66)>  (LINKNLOAD).
%      Called from CAGET <CaWave.pro( 391)>.
%      Called from $MAIN$ .

I note that the current version of cawave.c dates back to 1993 and
the documentation refers to version 4.01 of PV-WAVE. Is there a possible
incompatibility between the 'so' and the latest version of PV-WAVE?

Any help would be greatly appreciated.

Cheers,

Andy
