    5 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.

    77Also, 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.

     9EDIT: The spkg I made is at

     13I 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.

     15QEPCAD 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.

     17Another thing that would be good to include is Chris Brown's SLFQ program
