[Nestedvm] Problem with gcc 3.3.6

Thu May 12 10:07:47 EDT 2011

After some search I think the problem is that there is no main method in 
the libraries. So I played around with some parameters and with the 
following combination I don't get the error anymore:

mips-unknown-elf-gcc -g -c -Wall ...

But I'm not sure if it is ok to use -c because it doesen't link. Is it 
ok not to link?

Now I get the error from the org.ibex.nestedvm.Compiler that the binary 
is not an executable. I'm sure that this is a result of not having a 
main methof and using the -c parameter.

Has anyone a hint how I can put the things together now? The whole 
directory of cpp files I want to nest contains about 20 cpp files. I 
cant't write a main for each of the files. Is it somehow possible to 
"bundle" them together and give them one main so that the nestedvm java 
compiler can compile it?

Regards

Andre
