I tryed this:
libjava/include/no-threads.h
struct ParkHelper
{
void init ();
void deactivate ();
void destroy ();
void park (jboolean isAbsolute, jlong time);
void unpark ();
};
libjava/no-threads.cc
void ParkHelper::init () {}
void ParkHelper::deactivate () {}
void ParkHelper::destroy () {}
void ParkHelper::park (jboolean isAbsolute, jlong time) {}
void ParkHelper::unpark () {}
But I got more errors on libjava/sysdep/arm/locks.h (thumb mode does not
recognize swp and swpne).

The java.lang.concurrent library requires thread support, so the only way you're going to get it to run with no threads is to create dummy definitions for ParkHelper. That should be easy, since null definitions for park() and unpark() will be fine. Just add these to libjava/no-threads.cc and libjava/include/no-threads.h.

--- Comment #6 from ramana at gcc dot gnu dot org 2009-04-20 14:30 --- Hi Andrew, > > > I'm not quite sure what you're trying to do. > > What did you change to support arm-eabi* ? I changed libjava/configure.host to also support arm-eabi (arm*-elf|arm*-eabi)but that probably wasn't enough. Given that arm-elf appears to be supported for this as per the last comment in the bug report, I thought it would make sense to have it working for arm-eabi. I decided to go back and try an arm-elf build as well just now. I get a failure with jni-libjvm.cc with an error about ParkHelper not naming a type. Hence this appears to be broken on trunk as revision 146222 for arm-elf as well as arm-eabi. Ramana > > Andrew. > -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32340

--- Comment #4 from ramana at gcc dot gnu dot org 2009-04-20 05:58 --- The build is broken currently for arm-none-eabi targets on trunk.
