linux - C linux 中的 Makefile 错误

Question

我在 linux 中制作 makefile 时出错。这是我的代码:

CC = gcc
CFLAGS = -Wall -m32 -g -fno-stack-protector -z execstack -O0
SHELL_SOURCES = Shell.c

SHELL = Shell

.PHONY: all target1 clean

all: target1 

target1: $(SHELL)

$(SHELL): $(SHELL_SOURCES)
    $(CC) $(CFLAGS) $^ -o $@

clean:
rm -rf $(SHELL)

我得到的错误是:

gcc -Wall -m32 -g -fno-stack-protector -z execstack -O0 Shell.c -o Shell
make: Shell: Command not found
Makefile:16: recipe for target 'Shell' failed
make: *** [Shell] Error 127

Answer 1

您不能将 SHELL 用作 Makefile 中的变量，它用于了解您的 Makefile 中将使用什么 shell(/bin/sh、/bin/bash 等)。

CC = gcc
CFLAGS = -Wall -m32 -g -fno-stack-protector -z execstack -O0
EXE_SOURCES = Shell.c

EXE = Shell


.PHONY: all target1 clean

all: target1 

target1: $(EXE)

$(EXE): $(EXE_SOURCES)
    $(CC) $(CFLAGS) $^ -o $@

clean:
    rm -rf $(EXE)
