Failure to load boost libraries on Linux
Hi Please will some one help me with what is probably a simple Linux error? I have installed Boost 1.40 on Centos 5.3 using an rpm from blackopsoft.com. When I run my executable I get: Failed to load the following library files: [snip] dlerror = libboost_python.so.2: cannot open shared object file: No such file or directory Executing: /sbin/ldconfig -p | grep boost gives: libboost_python-mt.so.1.40.0 (libc6,x86-64) => /usr/lib64/libboost_python-mt.so.1.40.0 libboost_python-mt.so (libc6,x86-64) => /usr/lib64/libboost_python-mt.so libboost_python-mt-d.so.1.40.0 (libc6,x86-64) => /usr/lib64/libboost_python-mt-d.so.1.40.0 libboost_python-mt-d.so (libc6,x86-64) => /usr/lib64/libboost_python-mt-d.so Please can anyone suggest what is wrong? Best regards David

Your executable is linked against something that is not system-wide boost on your machine. Probably, it is linked on a different machine, where boost libraries are named in a different way. Boost, when built from official release, will never create a library named libboost_python.so.2 - Volodya

Looks like your application is trying to load the single-threaded version of libboost_python but you don't have it installed? -- Dave Abrahams BoostPro Computing http://www.boostpro.com
Hi Dave
Looks like your application is trying to load the single-threaded version of libboost_python but you don't have it installed?
In my makefile I simply specify: LIBDEPEND+=-lboost_python LIBDEPEND+=-lpython2.4 g++ -shared -o [snip (object files)] $(LIBDEPEND) How would I link to the multi-threaded library instead please? David

Personally I would build it from source. Its very easy on Linux. You can just download the tarball from boost.org and follow the guide on the site on how to build it.
From the looks of the error message I cannot say for sure what is going on. Can you post the entire message? I would say off the start its looking for the non-multithreaded version.

Hi Thanks for all your replies and help. I simply needed to specify: -lboost_python-mt instead of: -lboost_python Sorry, I should have realised that much earlier. David
