Changing that manually fixed the issue. I'll look at patching gjavah
to do the right thing.
Continuing, I get more strange errors:
/home/andrew/projects/classpath/gcj/sources/gcc/libjava/gnu/gcj/util/natDebug.cc:
In static member function 'static java::lang::Object*
gnu::gcj::util::Debug::getField(java::lang::Object*,
java::lang::reflect::Field*)':
/home/andrew/projects/classpath/gcj/sources/gcc/libjava/gnu/gcj/util/natDebug.cc:73:
error: expected type-specifier
/home/andrew/projects/classpath/gcj/sources/gcc/libjava/gnu/gcj/util/natDebug.cc:73:
error: cannot convert 'int*' to 'java::lang::Object*' in return
/home/andrew/projects/classpath/gcj/sources/gcc/libjava/gnu/gcj/util/natDebug.cc:73:
error: expected ';'
/home/andrew/projects/classpath/gcj/sources/gcc/libjava/gnu/gcj/util/natDebug.cc:73:
error: 'Double' is not a member of 'gnu::java::lang'
natDebug.cc hasn't changed; any idea what could be wrong here?
Thanks,
