Running partcl on parrot [Was: Re: GCC failed with configure.pl]

Hi All,

I am trying to run a simple factorial program using parrot inside my C code.

This is from the embed_new.pod tutorial.

This line in the main function seems to be giving me some errors :

Parrot_api_load_bytecode_file(interp, "foo.pbc", &pf)


ashiva at ubuntu:~/Parrot/rakudo/Test$ gcc factorial.c `parrot_config
embed-cflags` `parrot_config embed-ldflags`
factorial.c: In function ‘main’:
factorial.c:65:5: warning: passing argument 2 of
‘Parrot_api_load_bytecode_file’ from incompatible pointer type [enabled by
default]
In file included from factorial.c:2:0:
../parrot/include/parrot/api.h:324:12: note: expected ‘Parrot_String’ but
argument is of type ‘char *’
ashiva at ubuntu:~/Parrot/rakudo/Test$

Can anyone please suggest what I can possibly do to avoid these errors and
run the pbc ?

Thanks & Regards,
Ashraya


Thanks & Regards,*
Ashraya S Shiva*
