超级菜鸟第一次用gcc有问题请教，在线等回答，谢谢

[sunnyorc]

因为计算需要运行一个linux下的程序，第一次使用Ubuntu，自己是电脑菜鸟，没有编程知识。敬请大家帮忙。

按照程序的manual

我输入>>gcc ssweep.c -o ssw -lm
得到结果：bash：swweep.c: command not found

请问-0和-lm是什么意思？
得到这个结果是什么意思？如何解决？

[sunnyorc]

此外，我运行sudo apt-get build-essential
显示：E:无效的操作 build-essential

怎么回事？

同一个原因，你输错了。从哪儿看到了，可以复制粘贴的

1:gcc ssweep.c -o ssw -lm 得到结果：bash：swweep.c: command not found :

you must add you directory or first cd to your directory, for example,

代码： 全选

gcc ~/ssweep.c -o ssw -lm 

or

代码： 全选

cd ~/ 
gcc ssweep.c -o ssw -lm 

2:sudo apt-get install build-essential

[slax]

of course,you can use some IDE like codeblocks anjuta and so on.

[sunnyorc]

thank you very much.

For the first question. I have cd to my directory and input right command. but the result is the same.

For the second question. slax is right. thanks

先找本基础教程 看一下，然后再有不懂的再来论坛问……

你不是把那个 >> 也输入了吧 ＝。＝　。。

莫非你和我一样，刚才scim崩溃了？

bash：swweep.c: command not found

好像gcc 被忽略了，莫非是真的把>>给打进去了？

将swweep.c 重命名 为 main.c 再将下面的文字复制成 makefile 文件放在同目录下，在终端下 make 运行

代码： 全选

# 源文件
c_source_files := main.c
c_header_files := 

# 输出文件
executable_files := main
object_files := $(patsubst %.c, %.o, $(c_source_files))

CFLAGS +=
LDLIBS +=

CFLAGS ?= -g -O0
CFLAGS += -Wall -Wextra


.PHONY: all
all: $(executable_files)
#------------------------------------
$(executable_files): $(object_files)
	$(LINK.o) $^ $(LDLIBS) -o $@
$(executable_files).o: $(c_source_files) $(c_header_files)
	$(COMPILE.c) $< -o $@
#--------------------------------------
# make clean
# 仅删除编译生成的.o文件，保留可执行文件和*.log
.PHONY: clean
clean:
	$(RM) $(object_files)
#------------------------------------
# make distclean
# 删除*.o、可执行文件以及*.log
.PHONY: distclean
distclean:
	$(RM) $(object_files)
	$(RM) $(executable_files)
	$(RM) $(log_files)
