Hi all,
I tried to install 3.14.12-pre2 on Windows on a different drive than the
one where I extracted the source code.
I tried to follow the example in configure/os/CONFIG_SITE.win32-x86.Common:
INSTALL_LOCATION = C:/epics/base-3.14.12
This does not work because make reads lines starting with C: as rules
for building the file C. Using \\ instead of / also does not help.
So I tried
INSTALL_LOCATION = /cygdrive/c/epics/base-3.14.12
Now the microsoft compiler fails because it cannot read the cygdrive
path and thus cannot find the header directories. Here the problem is
that the PATH_FILTER only replaces / with \\ but not /cygcdrive/c with c:
Unfortunately make seems not to have any function to replace
/cygdrive/drivename/path with drivename:path for arbitrary drivenames.
Then I tried to replace
PATH_FILTER = $(subst /,\\,$(1))
with
PATH_FILTER = $(shell cygpath -w $(1))
This does not work because PATH_FILTER is used not on the file names but
on the compiler options, e.g. in CONFIG_COMMON:

COMPILE.c = $(CC) -c $(CPPFLAGS) $(CFLAGS) $(call PATH_FILTER,$(INCLUDES))
Now cygpath gets arguments like "-I /filename" and does not know what
option -I is.
It seems the problem exists in all 3.14 revisions.
Can someone please fix this problem before the final release of 3.14.12?

Best regards,
Dirk
