Hi everyone, I need some help debugging a link error I am getting. I am trying to compile an application that uses boost, here is the error.

 

g++ -g -O2 -o .libs/sesame sesame-SysAgent.o sesame-Sysimage.o sesame-Package.o  -L/home/spervez1/db-4.6.21/build_unix/lib -L/home/spervez1/boost_1_49_0/lib\

/usr/bin/ld: warning: libboost_system.so.1.49.0, needed by /home/spervez1/boost_1_49_0/lib/libboost_filesystem.so, not found (try using -rpath or -rpath-link)

/home/spervez1/qpidc-0.14/src/.libs/libqpidcommon.so: undefined reference to `boost::system::generic_category()'

collect2: ld returned 1 exit status

 

I have boost installed in /home/spervez1/boost_1_49_0/

 

Here are the two commands that led to this error

 

CPPFLAGS="-I/home/spervez1/db-4.6.21/build_unix/include -I/home/spervez1/boost_1_49_0/include" LDFLAGS="-L/home/spervez1/db-4.6.21/build_unix/lib -L/home/spervez1/boost_1_49_0/lib" ./configure --with-qpid-checkout=/home/spervez1/qpidc-0.14 --with-db4-devel=/home/spervez1/db-4.6.21/build_unix --with-boost=/home/spervez1/boost_1_49_0/

 

make

 

I’ve researched some online and others have been able to solve this problem by adding the –lboost_filesystem flag which already exists in the makefile command so I’m a bit confused what the error could be. I’ll appreciate any input on this. Thanks.
