about compilers

Hi Huck,

> So if there is an --host option :./configure --host=nios-elf

Yes, this is the option you will need. The concept is the same: you need to add a "nios" entry to the

config.sub script. This is what configure will use when is checks for all of those magic options ;-)

Basically, it will attempt to use nios-elf-xxx when performing its tests. E.g. nios-elf-gcc, nios-elf-ld, etc.

Once the configure script knows what "basic machine" it's using (and therefore what prefix to use for

the binutils/gcc excutables), it will need to know the correct include and library paths. This is the

reason you need to set CPPFLAGS and LDFLAGS in your environment. For other architectures, such

as powerpc-linux, you normally don't need to do this, but for nios, you most likely will.

Since you're using Nios-32 (rather than Nios II), you will probably do well to use the cdk4nios as

Brendan suggested ... or bite the bullet and upgrade to Nios II ;-)

Good Luck,
