c - 尝试在 Ubuntu 的 makefile 中运行多个命令

Question

我正在尝试制作一个可以运行多个公共(public)并在不同目录中创建对象的 makefile

all: clean debug release 

debug:
gcc -g -o debug/client.o client.c
gcc -g -o debug/server server.c -pthread
gcc -g -Wall -o debug/serverLog -DLOGFILE server.c -pthread

release:

gcc -Wall -o release/client client.c
gcc -Wall -o release/server server.c -pthread
gcc -Wall -o release/serverLog -DLOGFILE server.c -pthread

clean: 
-rm debug/client 
-rm debug/server 
-rm debug/serverLog

Answer 1

我明白了

# "Debug" build - no optimization, and debugging symbols
DBG_FLAGS=-Wall -O0 -g

# "Release" build - optimization, and no debug symbols
REL_FLAGS =-Wall

all: debug release

debug: mkdirs
   gcc $(DBG_FLAGS) -o debug/client client.c
    gcc $(DBG_FLAGS) -o debug/server server.c
    gcc $(DBG_FLAGS) -o debug/serverLog -DLOGFILE server.c


release:mkdirs
    gcc $(REL_FLAGS) -o release/client client.c
    gcc $(REL_FLAGS) -o release/server server.c
    gcc $(REL_FLAGS) -o release/serverLog -DLOGFILE server.c

mkdirs:
   -mkdir debug
   -mkdir release


clean:
    -rm debug/* release/*
