如何让makefile支持多线程

Answer 1

在Linux下编译个多线程命令为:

gcc -lpthread -o file file.c

在Linux下用交叉编译器编译个在uc下运行多线程makefile文件如下:

CFLAGS = -Wall -Os -D -D__linux__ -Dunix -D__uClinux__ -DEMBED

LDFLAGS =-Wl,-elf2flt
LOCAL_LIBS = /usr/local/arm-elf/lib/libpthread.a

CC = arm-elf-gcc

LD = arm-elf-gcc

TARGT = test

OBJ = $(TARGT).o

SRC = $(TARGT).c

all: $(TARGT)

%.o:%.c

$(CC) $(CFLAGS) -c $< -o $@

$(TARGT) :$(OBJ) $(LOCAL_LIBS)

$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $(OBJ) $(LOCAL_LIBS) $(LDLIBS)

clean:

-rm -f $(EXEC) *.elf *.gdb *.o
