I'm checking compiling OpenJDK 6 on Ubuntu 8.04 beta using gcc 4.2.x
I got some compile errors in hotspot files that are compiled with
-Werror. The warning that got upgraded to an error had to do with
string constants being used with a "char *" of some kind.
In some cases there was a struct definition that had a "char *" which
then was initialized with a string constant. In other cases functions
were called where the parameter was declared "char *" but a string
constant given to it.
In the following patches I either changed the struct definition or made
a cast on the string constant, depending on the context.
I also had an intermittent failure on
In file included from .../hotspot/src/share/vm/opto/classes.cpp:36:
.../hotspot/src/share/vm/opto/classes.hpp: In member function
'virtual const Type* PartialSubtypeCheckNode::bottom_type() const':
.../hotspot/src/share/vm/opto/classes.hpp:309: internal compiler
error: Segmentation fault
All the above issues do not happen on my Ubuntu 7.10 machine that has
GCC 4.1.x installed. They happen on my Ubuntu 8.04 beta machine that
has GCC 4.2.x
