Hi Ben,
Here is how I have done this.
- Create an os/$(OS_CLASS) subdirectory.
For example:
corvette:areaDetector/ADBinaries/hdf5Support>ls os/WIN32/
COPYING H5DSpublic.h H5FDcore.h H5FDmpi.h H5FDpublic.h H5Fpublic.h H5LTpublic.h H5PTpublic.h H5TBpublic.h H5overflow.h H5public.h
H5ACpublic.h H5Dpublic.h H5FDdirect.h H5FDmpio.h H5FDsec2.h H5Gpublic.h H5Lpublic.h H5Ppublic.h H5Tpublic.h H5pubconf.h H5version.h
H5Apublic.h H5Epubgen.h H5FDfamily.h H5FDmpiposix.h H5FDstdio.h H5IMpublic.h H5MMpublic.h H5Rpublic.h H5Zpublic.h H5pubconf_32.h hdf5.h
H5Cpublic.h H5Epublic.h H5FDlog.h H5FDmulti.h H5FDwindows.h H5Ipublic.h H5Opublic.h H5Spublic.h H5api_adpt.h H5pubconf_64.h hdf5_hl.h
Then your Makefile can have this:
corvette:areaDetector/ADBinaries/hdf5Support>ls os/WIN32/
COPYING H5DSpublic.h H5FDcore.h H5FDmpi.h H5FDpublic.h H5Fpublic.h H5LTpublic.h H5PTpublic.h H5TBpublic.h H5overflow.h H5public.h
H5ACpublic.h H5Dpublic.h H5FDdirect.h H5FDmpio.h H5FDsec2.h H5Gpublic.h H5Lpublic.h H5Ppublic.h H5Tpublic.h H5pubconf.h H5version.h
H5Apublic.h H5Epubgen.h H5FDfamily.h H5FDmpiposix.h H5FDstdio.h H5IMpublic.h H5MMpublic.h H5Rpublic.h H5Zpublic.h H5pubconf_32.h hdf5.h
H5Cpublic.h H5Epublic.h H5FDlog.h H5FDmulti.h H5FDwindows.h H5Ipublic.h H5Opublic.h H5Spublic.h H5api_adpt.h H5pubconf_64.h hdf5_hl.h
This works fine with standard base I believe, including with "make -j".

Subject: Another build-system bug in 3.14.12
Hi
I tried to fix the INC_<osclass> problem "by hand" like this:
ifeq ($(OS_CLASS),vxWorks)
inc: $(INSTALL_INCLUDE)/os/$(OS_CLASS)/bla.h
endif
instead of defining INC_vxWorks. This seems to work.
Now, in my real application the build was still broken, but only when
using parallel make i.e. make -j. I reproduced this in my cut-down
example with the following Makefile:
"""
TOP = ..
include $(TOP)/configure/CONFIG
#-----------------------------------------------
# ADD MACRO DEFINITIONS AFTER THIS LINE
inc: $(INSTALL_INCLUDE)/os/$(OS_CLASS)/bla.h
LIBRARY_IOC += bla
bla_SRCS += bla.c
include $(TOP)/configure/RULES
#-----------------------------------------------
# ADD RULES AFTER THIS LINE
bla.h:
sleep 1
echo "struct x {int y; };" > bla.h
"""
(The bla.c is trivial and includes bla.h).
This fails with
franksen@tiber: ~/tmp/inc-bug > make -sj distclean && make -sj
../bla.c:1:17: fatal error: bla.h: No such file or directory
compilation terminated.
make[2]: *** [bla.o] Error 1
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [install.linux-x86] Error 2
make: *** [bugApp.install] Error 2
However, it works if I add an explicit dependency in the Makefile:
bla.o: bla.h
Inspecting the generated dependency makefile snippets shows why the
parallel build fails: they are empty:
franksen@tiber: ~/tmp/inc-bug > find -name *.d
./bugApp/O.RTEMS-mvme2100/bla.d
./bugApp/O.RTEMS-mvme5500/bla.d
franksen@tiber: ~/tmp/inc-bug > cat ./bugApp/O.RTEMS-mvme2100/bla.d
franksen@tiber: ~/tmp/inc-bug > cat ./bugApp/O.RTEMS-mvme5500/bla.d
Cheers
Ben
