suspect it has something to do with the script that handle symlinks. @patacongo
any ideas?
I never noticed, but yes it is a real problem. I have several old board and
and chip directories. We need to open an issue. These two lines in
arch/arm/src/Makefile (and other arch Makefiles) are not working under cygwin:
$(Q) $(DIRUNLINK) $(ARCH_SRC)/board
$(Q) $(DIRUNLINK) $(ARCH_SRC)/chip
Cygwin supports is own style of symbolic links and these are used EXCEPT for
the case where a Windows native toolchain is used such as the popular
(https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm).
Those are Window native tools and cannot follow non-standard Cygwin symbolic
links so in this case, the tools/dirlinks.sh script does a full directory copy
and the corresponding unlink script does a directory removal.
Without knowing more, it looks like the DIRUNLINK is failing to remove the
Cygwin symbolic link or the copied directory.
