I think you need to upgrade your version of Base; that command works fine on 
EPICS Base versions back to 3.14.10 (which came out well over two years ago), 
but not on 3.14.9:

tux% cat > db/wf.db
record(waveform, "waveform") {
    field(FTVL, "CHAR")
    field(NELM, "80")
}
tux% ~iocapps/R3.14.10/base/3-14-10-asd1/bin/linux-x86_64/softIoc -d db/wf.db
Starting iocInit

An error is only a mistake if you don't learn from it.
When you learn something from it, it becomes a lesson.
