to decide static or dynamic
-
Dear friends: I am creating a makefile.
Sometimes I can not execute dynamically and sometimes statically. So I want something like following but I do not know how to check in GNU.#makefile cc = g++ CFLAGS= -c -g -Wall -O3 -I. -DUNIX if (glibc-static c library exits in operating system), then CFLAGS1= -O3 -I. -DUNIX -static else CFLAGS1= -O3 -I. -DUNIX PROG = myprogram OBJS = file1.o file2.o $(cc) $(CFLAGS1) -o $(PROG) $(OBJS) file1.o: file1.cpp file1.h $(cc) $(CFLAGS) file1.cpp file1.h file2.o: file2.cpp file2.h $(cc) $(CFLAGS) file2.cpp file2.h PHONY: clean clean: rm $(OBJS)
I do not know how to check this in GNU make. Can anyone write me the codes for the following macro code for GNU make ?
CFLAGS= -c -g -Wall -O3 -I. -DUNIX if (glibc-static c library exits in operating system), then CFLAGS1= -O3 -I. -DUNIX -static else CFLAGS1= -O3 -I. -DUNIX
I would be very thankful

perhaps(?) compile and link a test.cpp with static lib, show if it worked, and call your makefile recursively with the new information.
