Do
pvget -h
to get help.
pvget defaults to using pvAccess protocol. That can only read normal IOC pvs if your IOC is running qsrv or equivalent.
To use pvget to use Channel Access do
pvget -p ca pvname
Example:
corvette:~>pvget -p ca 13IDA:m1
13IDA:m1 -0.25

Hello,
I have built latest epics-base branch 7.0 and R.7.0.2.1 on Windows 7 and CentOS 4.4.7.(tested both). I cloned with - - recursive option. When I am using caget(), it works, pvget() doesn't. It doesn't even print me an error message when I don't specify a PV. Behaves identical on both systems. When I specify a PV, request times out.
On this CentOS system I have only base built and nothing running
det@xf11bm-pilatus800k:~/epics/epics-base/bin/linux-x86_64> ./caget
No pv name specified. ('caget -h' for help.)

On this Windows 7 I have bunch of modules built and my new driver and IOC, which theoretically could be a contributing factor, but I don't think so.
C:\epics\epics-base>bin\windows-x64-static\pvget.exe
//prints empty line

I have another system with Debian 7.
On this Debian 7 I have bunch of ADProsilica and ADPilatus iocs running, built with base 7.0.1. At least pvget() responds with the correct complaint, though times out with a PV.

There is one system where pvget() does work. One year ago I built from core/master on Debian 8. This branch is closed now. On this machine I have one ADprosilica and one ADPointGrey IOC running with this base. There are other IOCs, but they use Debian distribution.
oksana@xf11id-m1:/opt/epics/ADepics7/epics-base/bin/linux-x86_64$ ./pvget XF:MOBILE-BI{Mir:1}cam1:AcquireTime
XF:MOBILE-BI{Mir:1}cam1:AcquireTime 0.3
oksana@xf11id-m1:/opt/epics/ADepics7/epics-base/bin/linux-x86_64$ ./caget XF:MOBILE-BI{Mir:1}cam1:AcquireTime
XF:MOBILE-BI{Mir:1}cam1:AcquireTime 0.3
oksana@xf11id-m1:/opt/epics/ADepics7/epics-base/bin/linux-x86_64$ git branch
* core/master
oksana@xf11id-m1:/opt/epics/ADepics7/epics-base/bin/linux-x86_64$
What I could be missing? Why pvget() does not work for me?
Thanks,
Oksana
