New description:
There exists a new upstream version of saclib (and qepcad) that compiles
on 64 bit machines at
!http://www.usna.edu/Users/cs/qepcad/INSTALL/IQ.html
Chris Brown says "Version 1.54 adds portability to 64-bit systems. Right
now, I can only verify that it compiles and runs properly on
64-bit Ubuntu ... hopefully it's also OK on other 64-bit linux
distros." I have built it outside of sage on 64 bit and 32 bit Debian
without major difficulty.
Also, I think there could be some improvements to the QEPCAD interface,
but it would probably be better for me to open separate tickets and base
them on the updated spkg.
EDIT: The spkg I made is at
!http://www.columbia.edu/~bg2382/sage/qepcad-1.54.p0.spkg
I have never made a spkg before, but it seems to build (on my machine) and
run a few examples (whereas the existing spkg segfaulted). If someone
wants to patch it further and upload it to the sage website, that would be
good.
QEPCAD B and SACLIB now build on 64 bit machines, so I put the pristine
sources into the src/ directory. I dropped all of Carl Witty's patches but
I revived two of them to link against ncurses. Possibly Carl's floating
point exception patch to SACLIB should be rebased too, but I couldn't tell
if that was just another bitness issue so cc'd.
Another thing that would be good to include is Chris Brown's SLFQ program
!http://www.usna.edu/Users/cs/qepcad/SLFQ/Home.html
which calls QEPCAD B. I have gotten SLFQ to build outside of sage with a
couple of patches, but I have not actually gotten it to work yet.
