The title of this report should be more like "Will not
compile under GCC 4.1.2.

The report included seems to indicate an error in GCC or
compile-time options; /usr/lib/gcc/i486-linux-gnu/4.1.2/
include/xmmintrin.h:34:3:
error: #error "SSE instruction set not enabled"

It should be on the architecture involved.

I'm glad you are a Project Coder, screamingwns, we need
those. Now, how does your remark help us? Do you suspect
other versions of GCC should be fine? Non-GCC compilers?

What does it mean:
> It should be on the architecture involved.
My architecture is i386. What can I do to help?

I am using GCC 4.1.0 and have not encountered this problem.

It is either:

1. A bug particular to GCC 4.1.2.

-or-

2. An error in the options passed to GCC (e.g. enabling MMX,
but not SSE, even though they should be available on your
arch / compiler).

It'll need to be investigated more thoroughly. I'm going to
be working on restructuring the code and re-writing the
Makefiles to make them smaller and easier to maintain. This
problem should hopefully correct itself in the process...

Added -msse option to makefile in 1765

Should now compile and emit MMX + SSE code (NB, will NOT
run on < P3 or < Athlon XP/MP.

This is a major oversight; the code should detect MMX, SSE,
SSE2 and SSE3 as well as 3D Now! and use seperate code
paths, as appropriate. This should be done purely with
default macros, i.e., those defined by specifying gcc -mmmx.

For archs that do not support SSE, you will be forced to
use BUILD_WITH_MMX=NO for now.

This is really an issue of optimisation, so will be a low
priority for now.

Thanks a lot. Now FPS in the credits screen jumped to 900
with the first guy walking and 500 on average (compared to
below 300 earlier). Though it can be other code changes, too...
