ld path update for compiling

I just installed manually apr and apr_util so i can install activemq c++ library.

When i try to make the cpp library i get the following error:

**

libtool: link: g++ -ansi -pedantic -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -I/usr/local/apr/include/apr-1 -I/usr/local/apr/include/apr-1 -I/usr/kerberos/include -W -Wall -Wextra -Wconversion -fPIC -fstrict-aliasing -Wstrict-aliasing=2 -Wno-long-long -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE -I/usr/local/apr/include/apr-1 -I/usr/local/apr/include/apr-1 -I/usr/kerberos/include -Wno-non-virtual-dtor -Wno-unused-parameter -Wno-uninitialized -I./../main -g -O2 -pthread -o .libs/example example-main.o ../main/.libs/libactivemq-cpp.so -lexpat -L/usr/kerberos/lib64 /usr/local/apr/lib/libaprutil-1.so /usr/local/apr/lib/libapr-1.so -luuid -lrt -lcrypt /usr/local/apr/lib/libexpat.so -lssl -lcrypto -ldl -lz -lpthread -pthread -Wl,-rpath -Wl,/usr/local/lib -Wl,-rpath -Wl,/usr/local/apr/lib /usr/bin/ld: cannot find -lexpat collect2: ld returned 1 exit status

**

and expat is within apr-util and not being linked. how can i update the ld path so that make or environment will find it?

or in short: how can i resolve this?

Usually you'll need to manually specify the library path using -L option.

It would look like ld filename -Lpath -llibname in a single ld operation. Or in this case you may need to add the paths of your library(apr-util here) to the constant of library paths in a Makefile.
