RFR: JDK-8179079: Incremental HotSpot builds broken on Windows (original) (raw)

We have hit another issue related to the new Cygwin behavior regarding \r line endings. The incremental native build on Windows breaks because we get ^M characters in the *.d files. Output from "make --debug=b" typically looks like this:

Prerequisite '/cygdrive/c/erik/jdk9-dev/hotspot/src/share/vm/adlc/adlc.hpp^M' of target '/cygdrive/c/erik/jdk9-dev/build/windows-x64/hotspot/variant-server/tools/adlc/objs/adlparse.obj' does not exist.

It's annoying to be fixing these one at a time like this, but I can't really see a general solution to the problem. Here is the simplest fix I could come up with for this particular problem:

diff -r 6832b2d9d1ae make/common/NativeCompilation.gmk --- a/make/common/NativeCompilation.gmk Fri Apr 21 11:31:09 2017 +0200 +++ b/make/common/NativeCompilation.gmk Fri Apr 21 16:48:11 2017 +0200 @@ -165,6 +165,7 @@ WINDOWS_SHOWINCLUDE_SED_PATTERN :=
-e '/^Note: including file:/!d'
-e 's|Note: including file: *||' \

This sed expression is used to rewrite the output of CL's -showIncludes into a list of header files with absolute unix paths.
