[Sablevm-developer] Re: [Sablevm-user] can't create vm

[Chris P. <chr...@ma...>]

Hi,

You can probably help most by learning a little of gdb and stepping
through the execution.

e.g.
$ gdb sablevm TestProgram
(gdb) break main <-- set a breakpoint in the main method
(gdb) 'r' <-- for run
(gdb) list <-- to list source

and then use 's' (step) and 'n' (next) and 'break' to get to the problem.

Probably it is easier to run gdb through an interface like emacs (M-x
gdb) or ddd, because they update where you are in the source file as you
issue commands.  Personally I like emacs because it doesn't depend on X
-- try splitting emacs vertically with 'C-x 3' and then running gdb in
one window / frame / whatever-they're-called -- I think the default
splits horizontally and you don't get to see so much source at once.

You're looking for a point where JNI_CreateJavaVM () returns JNI_ERR and
thus causes the "cannot create vm" message to be printed.

Cheers,
Chris

P.S.  I can't add this to the wiki right now because I can't connect to
