Add .so and .a libraries to Makefile

I have a makefile which looks like this .

DEFINES=-std=c++0x
INCS_GTK=-I/usr/include/gtk-2.0 -I/usr/include/glib-2.0 -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/gtk-2.0/gdk -I/usr/include/pango-1.0 -I/usr/lib/gtk-2.0/include -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -I/usr/lib/x86_64-linux-gnu/gtk-2.0/include
INCS=-I/usr/include/freetype2 -I/usr/include/mysql -Iframeworks ${INCS_GTK}
LDLIBS=-lconfig++ -lcxcore -lcv -lGL -lGLU -lglut -lhighgui -lSDL -lftgl -lueye_api -lboost_filesystem -lboost_system -lann -lpthread -lflycapture -lglog -lmysqlpp -lmysqlclient -lunittest++
DEBUG=-g -pg
WARNINGS=-Wall -Wextra -pedantic -Wno-long-long #-O3 -Weffc++
BUILDDIR=build
BINDIR=dist

MAINCXX=${shell find -name '*.cxx'}
TARGETS=${MAINCXX:%.cxx=%}
CXXFLAGS=${DEBUG} ${WARNINGS} ${DEFINES} ${INCS}
LDFLAGS=${DEBUG} ${WARNINGS} ${DEFINES}
include IDEconfigs/Makefile/generic.mk


I want to add the following paths of static libraries to the makefile .

/usr/local/lib/libYARP_OS.a /usr/local/lib/libYARP_sig.a /usr/local/lib/libYARP_math.a /usr/local/lib/libYARP_dev.a /usr/local/lib/libYARP_name.a /usr/local/lib/libYARP_init.a


how do i go about doing this .

Answer

Lets consider your /usr/local/lib/libYARP_OS.a.

What you can do is, have -L/usr/local/lib/ in your makefile as one of the variables. And then you can have -lYARP_OS appended to the LDLIBS.

-L is for path to the lib and -l is the lib name here libYARP_OS.a will be passed as -lYARP_OS.

On the command line you would do something like: gcc -o main main.c -L/usr/local/lib/ -lYARP_OS. This should give you an idea.
