我的mac上编译不过去是什么原因啊？

我克隆skynet_package修改skynetPath后还是不行

make: *** [../skynet/cservice/package.so] Error 1

我在cservice里面没有找到package.so这个文件啊
../skynet/cservice/package.so

修改的makefile里skynet path

# Use your path
SKYNET_PATH = ../skynet
TARGET = $(SKYNET_PATH)/cservice/package.so

$(TARGET) : service_package.c
	gcc -Wall -g --shared -fPIC -o $@ $^ -I$(SKYNET_PATH)/skynet-src

clean :
	rm $(TARGET)

换 linux 或者自己编写 mac 下的 makefile .

[tangyiyang]

mac上编译的时候，让Undefined Symbol去动态查找就好，加上
-undefined dynamic_lookup

这个问题可以关了。
如果很懒的话复制下面的Makefile吧。:)

SKYNET_PATH = skynet
TARGET = cservice/package.so

$(TARGET) : src/service_package.c
gcc -Wall -O2 --shared -fPIC -undefined dynamic_lookup -o $@ $^ -I$(SKYNET_PATH)/skynet-src

socket :
cd lsocket && $(MAKE) LUA_INCLUDE=../skynet/3rd/lua

clean :
rm $(TARGET)

我试过了 不行呢。。。。
还是一样的错误

谢谢楼上 参考你的makefile可以跑啦 谢谢你

[elenno]

make时报错 make: *** [cservice/package.so] Segmentation fault: 11 完全没搞懂这是什么报错
原来是机子的gcc有问题。 把gcc改为$(cc)就解决了
