Internal GCC builds of GMP and MPFR in Chapter 5?

[randy@…]

This was discussed on -dev and there really was no consensus reached, so I'm raising this ticket just so that we may come to some conclusion.

Should we modify Chapter 5 GCC-Pass2 so that the GMP and MPFR packages are built internally by GCC as they are in Pass1?

It probably makes no real difference.

[randy@…]

Just to give this a bump, and perhaps some other comments, but I'm inclined to go with Jeremy's suggestion that we abandon the builds of GMP and MPFR in Chapter 5 and just include them internally in the GCC Pass2 like is done in GCC Pass1.

Would like some input from others. Just for the record, over at DIY, Greg builds them internally with GCC.

Hi Randy,

I, too, don't see any value in having them available as external libraries in chapter 5. Building them internally as per GCC Pass1 makes sense to me, and it keeps chapter 5 self-consistent. That, in itself, may reduce questions to -dev and -support along the lines of "why do you compile GMP & MPFR differently between pass1 and pass2?".

Regards,

Matt.

Thanks for the input, Matt. I'll get this done today.

Modified the Chapter 5 instructions so that instead of building the GMP and MPFR packages separately for GCC Pass2, they are built by GCC internally.
