Hi,
I'm a newbie at VPython and could use a hand.
I have managed to compile VPython in a modified Mandrake 8.2
using gcc-2.96. When I try to run the demos I get:
ImportError: /usr/local/lib/python2.2/site-packages/cvisualmodule.so: undefined symbol: __ti3ios
I do know that it menas that cvisualmodule.so was loaded but it refers to
the symbol __ti3ios which is missing.
Running ldd cvisualmodule.so I get:
libstdc++.so.5 => /usr/local/lib/./libstdc++.so.5 (0x4034c000)
libgtkgl.so.5 => /usr/lib/libgtkgl.so.5 (0x40417000)

libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40ac0000)
Does anybody know who's to blame and what can I do to fix it or
at least to investigate it further.
Please carbon-copy your answers to rs...@ac... because I'm not yet a
memeber of this mailing-list.
Thanks in advance

Thank you Jonathan. This was the outcome: ----------------------------------------------------------------------------- [rodrigo@Goku rodrigo]$ cd /usr/local/lib [rodrigo@Goku lib]$ nm -o -D `ls libstdc++*.so libstdc++.so*` | grep __ti3ios nm: libstdc++.so@: No such file or directory nm: libstdc++.so@: No such file or directory nm: libstdc++.so.5@: No such file or directory [rodrigo@Goku lib]$ cd /usr/lib [rodrigo@Goku lib]$ nm -o -D `ls libstdc++*.so libstdc++.so*` | grep __ti3ios libstdc++-3-libc6.2-2-2.10.0.so:0004c214 B __ti3ios nm: libstdc++.so.3@: No such file or directory ------------------------------------------------------------------------------- Apparently libstdc++-3-libc6.2-2-2.10.0.so has the "missing" symbol. What is the best way tho made it available to VPython ? Tweak Makefile settings with a -lstdc++-3-libc6.2-2-2.10.0 ? Create a symbolic link ? In that case what is the expected name ? Anyway, Thanks for your help. best regards Rod -- Rodrigo Senra <rs...@ac...> GPr Sistemas http://www.gpr.com.br PUC-Campinas http://docentes.puc-campinas.edu.br/ceatec/rodrigo IC - Unicamp http://www.ic.unicamp.br/~921234 |

In that case what is the expected name ? It means that your C++ compiler is not setup right. IIRC, libstdc++ 5 is used by GCC 3.2, and the older libstdc++ 3 is used by GCC 2.95. You said before that you are using 2.96, which I assume is the same thing. There should be one and only one symbolic link from libstdc++.so to whatever library is appropriate for the compiler you want to use. Either rebuild Visual with GCC 3.2 or fix your link and then rebuild visual with GCC 2.96. -Jonathan Brandmeyer |
