In my RHEL linux (no root permission), my program does not find boost installation and says: *** Please install package libboost-filesystem to /home/myself/folder *** Please install package libboost-system to /home/myself/folder
I installed latest boost using these instructions.
./bootstrap.sh ----with-libraries=filesystem,system --prefix=/home/myself/folder
./bjam install
Can you tell, what is wrong I am doing and anything to add in include path etc.
My paths:
echo $LD_LIBRARY_PATH /home/myself/folder/lib:/home/myself/ddrive/test/boost_1_49_0/stage/lib
echo $CPLUS_INCLUDE_PATH /home/myself/folder/include/
My program has makefile:
LD_LIBS += -lboost_filesystem -lboost_system (and others)
LD_LIBRARY_PATH is the env variable for the linker, you must also set the LIBRARY_PATH for running a programm. A program searches the LIBRARY_PATH first for the libraries. The linker does not search the LIBRARY_PATH, it uses the LD_LIBRARY_PATH
Not quite. The regular linker doesn't look anywhere indicated by an environment variable. It just looks in the system locations and wherever specified with a -L flag when linking. His error seems to be from some build system, not his compiled program. He needs to provide parameters like "-L/home/myself/folder/lib" to it, typically in the form of LDFLAGS or similarly named parameters. LD_LIBRARY_PATH is for the dynamic linker to resolve shared libraries at runtime, it has no role at linking time. -- Lars Viklund | zao@acc.umu.se
