After we built the GCC toolchain for the Dreamcasts
Hitachi SH4 processor we still have one more processor
which we may be needed to program. It's the ARM processor
which is used by the Dreamcast for sound-processing.
We will use the same directory structure we already used
for building the SH4 toolchain which looks like this:
Now everything is set to compile the whole xGCC
toolchain for the ARM processor.
IMPORTANT:
(just in case you're doing the whole compilation stuff
not in one)
In case any compile process throws errors concerning a variable
called sys_errlist (it being declared twice)
you have to change the file /usr/include/sys/errno.h.
Search for the variable in question and change the following
lines to:
/* Please don't use these variables
directly.
Use strerror instead. */ // extern __IMPORT _CONST char * _CONST _sys_errlist[];
extern __IMPORT int _sys_nerr;
#ifdef __CYGWIN__ // extern __IMPORT const char * const sys_errlist[];
