Hi,
I am quite new to building gcc and resolving related issues. This is
probably a general question regarding porting gcc. I have obtained gcc
sources for PIC30 from Microchip but they seem to be broken/incomplete.
When the xgcc attempts to build libgcc2.c module. It turns out that the
xgcc is not able to compile a 'void function'(see the error below).
I am sure the problem is not trivial, but maybe could some one point me to
what the machine definitions in case of any architecture should be
checked? Or at least could someone confirm my theory that if the xgcc is
not capable of doing a certain thing and emits a syntax error, it is due
to some incompleteness in the machine definitions?
Please, CC me, since I am not subscribed to the list.
Best regards,
Jan Capek
The compiler error is below. The declaration that it dies on is a simple
void function:
extern void *malloc (size_t);
