I too have had some problems building jdk7 on cygwin. I believe they are
caused by

summary: 6360517: ALT_MSDEVTOOLS_PATH and rc.exe location, and rebase location
I am in the process of submitting a CR with my findings.
FWIW, my workarounds are in jdk file Defs-windows.gmk:
1. makefile assumes cygwin is at c:/cygwin which isn't true for me.
Workaround is:
ifdef USING_CYGWIN
CYGPATH_CMD=cygpath -a -s -m
CYGWINHOME:=$(shell $(CYGPATH_CMD) /)
# All possible drive letters
drives=a b c d e f g h i j k l m n o p q r s t v u w x y z
# Convert /cygdrive/ paths to the mixed style without an exec of cygpath
# Must be a path with no spaces.
define MixedPath
$(patsubst /%,$(CYGWINHOME)/%,$(sort $(filter-out /cygdrive/%,$(foreach drive,$(drives),$(patsubst
/cygdrive/$(drive)/%,$(drive):/%,$1)))))
endef
2 $(call MixedPath,/cygdrive/j) returns empty . Workaround is:
define FullPath
$(shell $(CYGPATH_CMD) $1 2> $(DEV_NULL))
endef
3. I was setting ALT_UNIXCOMMAND_PATH to /usr/bin and had to change it to /bin
This could have been a side effect of the first three issues.
I don't know if these workarounds would work for you or not.

Hi All,
I recently built OpenJDK again from sources obtained from Mercurial repos
(Windows x86_64/cygwin).
I used the same steps and configuration that I did (and succeeded) before with
Bundle sources I download from the webpage.
However, this time I got some unexpected error:

cygwin warning:

Preferred POSIX equivalent is: /cygdrive/c/WINNT/system32/wscript.exe
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
jdk/make/common/shared/Compiler-msvc.gmk:150: *** COMPILER_PATH cannot be empty
here. Stop.
*********************************************************************
The warning and error is unreasonable since all the mentioned environment
variables were set (see my configuration scripts: buildenv.bat below). And when
I check the output directory (D:/Tools/openjdk/jdk7_b121_x86_64_mer), there is
no content inside even a log for sanity check.
As I said, with the same steps and configuration file, I succeeded building the
OpenJDK Bundle. I want to take the course from Mercurial repos because it has
src\share\tools\ProjectCreator that the bundle version does not have.
Could someone please explain what happened and help me through this problem?
Thank you,
/Nhan
