When I tried to build Python 2.4.1 on doublehelix I ran into two problems:
- configure wouldn’t complete, saying that it couldn’t run compiled C programs. I looked at the configure script and right before this it had something about not removing this section with autoconf 3.0:
# If not cross compiling, check that we can run a simple program.
- make ran fine until it tried to use python to build the extension modules (or if I tried to run python manually once it was built). I got “./python: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory”
There’s a lot of stuff online about this problem, and generally the solution is to either modify /etc/ld.so.conf to include a path to the library, or put the path on LD_LIBRARY_PATH. I don’t have access to /etc/, so the second seemed like the best plan. A simple ‘find / -name libstdc++.so.6’ found three files with the right name, so I put the first one (/usr/local/lib) into LD_LIBRARY_PATH.
Unfortunately, this didn’t work – nothing seemed to change at all. I tried lots of other things, but nothing worked.
The problem turned out to be that although they all had the same name, the three libstdc++.so.6 files were not the same (I imagine that one is specific to 64 bit compiling). If I put the one in /lib64/ssa on LD_LIBRARY_PATH, all worked nicely (what normally goes into /lib64/ssa, I do not know).
