LD_LIBRARY_PATH

how do I get rid of exporting LD_LIBRARY_PATH (to get rid of " error
while loading shared libraries") while compiling it self in the
Makefile.

how to incorporate some kind of export statement in Makeifle ??

In general, you can get rid of LD_LIBRARY_PATH by using -L instead.

You may also want to produce executables that don't need LD_LIBRARY_PATH
set when it is time to run the executable (after build). In order to do
that, try using the -R or -rpath options to pass the path where the library
will actually be installed. Some compilers may require you to put a "-Wl,"
in front of "-rpath" in order to pass the flag through to the linker, so
you may need to use "-Wl,-rpath" instead of just "-rpath" in some cases.

If by "export statement", you mean that you wish to set an environment
variable in the Makefile, you can do that, but it's not usually a good
way to solve the problem.

You can add the path to the directory containing libraries by defining
the variable LIBS in the Makefile as shown below:

LIBS=-L/path/to/libdir -lmylib -lm -lpthread

where mylib is the name of your library file

and then use this variable while compliling your program
test:test.o
$(CC) -o test test.o $(LIBS)

or alternatively, to use export statement add the following entry in
your Makefile

LD_LIBRARY_PATH=-L/path/to/libdir

export LD_LIBRARY_PATH
