Hi Erik,
Because the flags' macro of MIPS is different from other targets[1], it
will effect the `UnixConstants` of
src/java.base/unix/classes/sun/nio/fs/UnixConstants.java.template, for
example, PREFIX_O_APPEND, so the `Flags` in `FileChannel` is different
from other targets. Then failed[2] to cross compiling jdk12 for
mips64el-linux-gnu target by following the document[3].
Workaround 1:
Only make hotspot, then scp
build/linux-mips64el-normal-server-fastdebug/jdk/lib/server/libjvm.so to
mips64el target machine, java version is able to work[4], but it needs
to make images on mips64el target machine at first.
Workaround 2:
Just change[5] the flags' macro of MIPS to keep same with other
targets. Even if succeed to cross compiling, and java version is able
to work on target machine, but jmod[6], javac, etc. failed to work.
Because buildjdk/jdk/bin/jmod is x86-64, but images/jdk/bin/jmod is
mips64el target, the flags' macro is still different in X86 host and
MIPS target machine.
Please give me some advice about how to fix the root cause, thanks a lot!
Regards,
Leslie Zhai
