dear Experts, please help, actually i am trying to create a .so(shared object through make file through ld) i am not understaning how to proceed i have tried like through command like i can do it in 2 step like my progam :test2.c Code:
$gcc -fPIC -c test2.c $ld -shared -soname test2.so -o test2.so -lc test2.o this gives me so but same thing i am trying to achiee through Makefile Code:
PROGRAM = test2.c INCLUDEDIRS = \ -I$(ARCENGINEHOME)/include \ -I/usr/X11R6/include LIBDIRS = \ -L$(ARCENGINEHOME)/bin \ -L/usr/X11R6/lib LIBS = -larcsdk //here it is giving me error CXXSOURCES = test2.c # list of source files CXXOBJECTS = $(CXXSOURCES:.c=.o) # expands to list of object files CXXFLAGS = -DESRI_UNIX $(INCLUDEDIRS) CXX = g++ LDFLAGS = $(LIBDIRS) $(LIBS) all: $(PROGRAM) $(PROGRAM): $(CXXOBJECTS) $(CXX) -o $@ $(CXXOBJECTS) $(LDFLAGS) basic_sample.o: basic_sample.cpp basic_sample.h $(CXX) $(CXXFLAGS) -c -o basic_sample.o basic_sample.cpp clean: $(RM) -f $(CXXOBJECTS) $(PROGRAM) run: ./$(PROGRAM) [/code] but here i want to add test.a which takes the object files like Code:

I think this would be better placed in the High Level Programming - The UNIX and Linux Forums forum. I assume Code:
PROGRAM = test2.c should be something like Code:
PROGRAM = test2 Since you already have the commands to create static and shared libraries, all you have to do is add to the makefile the library as a target, the object files as dependencies and put this command as the rule, e.g. Code:
test2.so: test2.o
ld -shared -soname test2.so -o test2.so -lc test2.o
test2.a: test2.o
ar -ur test2.a test2.oand then run make test2.a test2.so to see if it works. You can then (and perhaps should) generalise the rules with automatic variables and so on. |
