patacongo opened a new issue #1880:
URL: https://github.com/apache/incubator-nuttx/issues/1880
Under Cygwin, the following directories are not being removed by the
distclean target:
arch/<arch>/src/board
arch/<arch>/src/chip
I have several old board and and chip directories left over from
unsuccessful distclean operations on different architectures. These two lines
in arch/arm/src/Makefile (and other arch Makefiles) are not apparaently 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.
