ocelot: error while loading shared libraries: libboost_iostreams.so.1.55.0: cannot open shared object file: No such file or directory
Solution:
env LD_LIBRARY_PATH=/usr/local/lib
But Canonical is not recommend LD_LIBRARY_PATH.
You will see white page of frontend and stuck make the Ocelot of backend.
/usr/bin/ld: site_comm.o: undefined reference to symbol 'pthread_create@@GLIBC_2.2.5'
/lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
You can use LIBS for -lpthread.
But white page still not answer.
