Building JDK8 b106 with sysroot and isystem

[Jungwoo Ha]

Hi,

I am trying to build jdk8 b106 with customized compiler and libc.
I'm trying to add sysroot and isystem wherever necessary.
The new configure seems to have --with-extra-*flags and --with-sys-root,
but here are problems I found so far.

1) It doesn't seem that --with-sys-root/--with-extra-*flags parameter is
actually used during the compilation
2) When specifying --with-tool-dir, configure script doesn't use
--with-sys-root to check if the compilation and linking is done correctly.
3) LDFLAGS doesn't work all the time. Many makefile still contains old
LFLAGS.
4) I can add these flags on CFLAGS and CXXFLAGS, but jdk/ doesn't propagate
these properly.
5) For example,  BUILD_GENSRC_SOR_EXE in jdk, when calling
SetupNativeCompilation, it doesn't pass CXXFLAGS.

So are these new configure & make still work-in-progress, or
are these supposed to work?

Thanks,
Jungwoo
