I tried to build base 7.0.6 on windows-x64 using “make –sj8” on an 8-core machine.  It failed as follows:

The above files and dbCommon.dbd are built within modules/database/src.

The recTestIoc.dbd file is created within modules/database/test/std/rec which is built as a subdirectory of modules/database/test. There is a hard dependency specified in modules/database/Makefile so it isn’t supposed to be possible to start building in the test directory until the src directory has finished building:

DIRS += src

DIRS += test

test_DEPEND_DIRS = src

Thus I’m having difficulty imagining how that failure can occur (I’m not saying it couldn’t, I just don’t see how at the moment). How repeatable is the failure?

Running make –sj8 again appeared to work although it started with this message:

 

H:\epics-devel\base-7.0.6>make -sj8

'..' is not recognized as an internal or external command,

operable program or batch file.

asTestLib.c

dbHeaderTest.c

arrayOpTest.c

…

Those .c files are compiled in the modules/database/test/std/rec directory, which makes sense given the failure above. I’ll see if I can work out what the ‘..’ program might have been in case it provides more clues.
