I've recently migrated some Maple-based research to an 4-way AMD 64-bit system running Linux Ubuntu 9.10 (Karmic Koala). installed Maple 11.02, and thanks to previous forum posts I was able to resolve the blank document window problem, and was able to install a version of libstc++.so.5 that is required by NLPSolve in this version of Maple. Although I picked it up in a forum that claimed to distinguish between 32-bit 64-bit versions, it looks like I'm not out of the woods yet. In response to an Optimize call, Maple returned
Error, (in Optimization:-NLPSolve) external linking: error loading external library libmplfloat.so: libstdc++.so.5: wrong ELF class: ELFCLASS32
Maple 11.02, X86 64 LINUX, Nov 9 2007 Build ID 330022
and for the library environment (my $MAPLE is /usr/local/Maple11)
(that last one is a link to the lib32 version)
ls -l /usr/local/Maple11/bin.X86_64_LINUX/libstdc++.so.5
lrwxrwxrwx 1 root root 29 2010-03-22 15:25 /usr/local/Maple11/bin.X86_64_LINUX/libstdc++.so.5 -> /usr/lib32/libstdc++.so.5.0.7
So it seems that the 32-bit version really is a 32-bit version. If you could advise where I might obtain a version of these two libraries that will work in my 64-bit environment, I would be very grateful. It sure would beat shelling out for a new version of Maple right now.
Thanks in advance for your thoughts!
