Greetings,

Does anyone have experience compiling povray 3.50c under Linux using a
non-gcc compiler suite? I am running on AMD Opteron processors and was
curious to see if povray performance wouold improve (and by how much) using
an arch optimized compiler suite like Portland Group or Absoft.

Also, if anyone has used gcc to compile povray and used AMD's AMKL math
kernel libs I'd be interested in your results and any differences in
performance.

If I am proceeding down a senseless tangent feel free to tell me so.. =)

Thanks,

Jeff

	Although I never tried anything but gcc on Linux (not even icc,
what a shame !), I cannot tell anything but to edit the Makefile.in files
in the current source distribution of povray-3.50c, particularly that
in the src/ directory.  Find the CFLAGS and CXXFLAGS definitions which
are currently gcc-specific, and adapt to the options of your compiler.
Such necessary file editing should essentially disappear in the next
povray release.

	If you find your compile to be more efficient (speedwise) yet
producing the same results (images) than a gcc-made binary (or at least
the official povray linux binary), feel free to share your experience.
New sets of compilation flags could be inserted in the future configure
script of the source distro.
