Re: compilation error on pvData wrt epics base

["Johnson, Andrew N." <anj@aps.anl.gov>]

Hi Han

When you wrote “install pvData (in source directory)” what did you mean, and did you edit the pvData/configure/RELEASE file? I suspect you are not configuring the pvData module correctly.

Unless you’re using EPICS 7 or the fully bundled 4.7 release you need to treat each of the PVA modules as a regular support module, installing them in their own area and editing the configure/RELEASE files as appropriate (there should be comments in each file explaining what other modules they need to point to). It is also possible to set a value for INSTALL_LOCATION to a common directory in the modules’ CONFIG_SITE file, in which case you don’t have to worry about editing the RELEASE files.
