Hey guys, I am having trouble linking my boost libraries to a program I am trying to install. I need to install boost versions above 1.37 and ubuntu doesn't have packages yet for anything above 1.35. I am trying to install this program: http://webapp.dam.brown.edu/wiki/SciComp/InstallHedgeFromGit I followed the steps in his wiki but I always get this error message: g++ -pthread -shared -Wl,-Bsymbolic-functions build/temp.linux-x86_64-2.5/src/cpp/cuda.o build/temp.linux-x86_64-2.5/src/cpp/bitlog.o build/temp.linux-x86_64-2.5/src/wrapper/wrap_cudadrv.o build/temp.linux-x86_64-2.5/src/wrapper/mempool.o -L/home/supacreative/pool/include/lib -L/usr/local/cuda/lib -lboost_python-gcc41-mt -lcuda -o build/lib.linux-x86_64-2.5/pycuda/_driver.so /usr/bin/ld: cannot find -lboost_python-gcc41-mt collect2: ld returned 1 exit status error: command 'g++' failed with exit status 1 I can't get past this error. I've tried using the export command using: export LD_LIBRARY_PATH=/home/(my username)/pool/lib:$LD_LIBRARY_PATH and I still get the same error message. I even added the library folder into my ld.so.conf.d and ran ldconfig to restart ld, but I still get the same error. Please help. Jan
