I have to build my code for two different platforms at once using two different compilers and libraries. How can I do this with single make file.
Currently my makefile contents are given below. How can I instruct it to change the compiler to gcc within the same makefile?
VPATH = /root/Documents/project/src
CROSS_COMPILE = /opt/compilers/bin/compiler1
CXX = $(CROSS_COMPILE)-g++
CC = $(CROSS_COMPILE)-gcc
AS = $(CROSS_COMPILE)-as
AR = $(CROSS_COMPILE)-ar
NM = $(CROSS_COMPILE)-nm
LD = $(CROSS_COMPILE)-ld
OBJDUMP = $(CROSS_COMPILE)-objdump
OBJCOPY = $(CROSS_COMPILE)-objcopy
RANLIB = $(CROSS_COMPILE)-ranlib
STRIP = $(CROSS_COMPILE)-strip
CFLAGS = -c -Wall -D_REENTRANT -DACE_HAS_AIO_CALLS -D_GNU_SOURCE -DACE_HAS_EXCEPTIONS -D__ACE_INLINE__
LDFLAGS = -L. -L/etc/ACE_wrappers/lib
CPPFLAGS += -I/etc/ACE_wrappers -I/etc/ACE_wrappers/ace
LDLIBS = -lACE
OUTPUT_DIRECTORY=/root/Documents/bin
OBJ=/root/Documents/obj
ifneq ($(OUTPUT_DIRECTORY),)
all: $(OUTPUT_DIRECTORY)
$(OUTPUT_DIRECTORY):
-@$(MKDIR) "$(OUTPUT_DIRECTORY)"
endif
ifneq ($(OBJ),)
all: $(OBJ)
$(OBJ_DIR):
-@$(MKDIR) "$(OBJ)"
endif
