[英]How to make 'make' work with mingw32 on Windows 7
I'm pretty new to C and to programming so I hope you guys have a little patience. 我对C和编程还很陌生,所以我希望你们有一点耐心。 However I try to describe my problem as precise as possible.
但是,我尝试尽可能精确地描述我的问题。 I'm using mingw32 on my Windows 7 computer and I just learned about 'make'.
我在Windows 7计算机上使用mingw32,而我刚刚了解了“ make”。 I have written some source-code files and a Makefile.
我已经写了一些源代码文件和一个Makefile。 What I want is, that the Makefile compiles my source-code int object code and then link it together to one executable (I guess that's nothing wild for a pro).
我想要的是,Makefile编译我的源代码int目标代码,然后将其链接到一个可执行文件(我想这对专业人士来说并不算什么)。
So here is my code: 所以这是我的代码:
first.c: first.c:
#include<stdio.h>
#include"second.h"
int main()
{
float x = 12.0;
printf("Result is: %.2f\n",go_to_the_other(x));
return 0;
}
second.h second.h
float go_to_the_other(float f);
second.c second.c
float go_to_the_other(float f)
{
float calc = f + 10;
return calc;
}
And the Makefile is (and yes, I used only tabs): Makefile是(是的,我只使用制表符):
second.o: second.c second.h
gcc -c second.c
first.o: first.c
gcc -c first.c
first: first.o second.o
gcc first.o second.o -o first
This is just an easy example, but it pretty much describes my problem. 这只是一个简单的例子,但是它几乎描述了我的问题。 I have all files in the same directory, and I use the command line:
我所有文件都在同一目录中,并且使用命令行:
mingw32-make first
But instead of compiling my files, I only get the message: 但是我没有编译文件,而是得到以下消息:
cc first.c -o first
process_begin: CreateProcess(NULL, cc first.c -o first, ...) failed
make (e=2): The system cannot find the file specified.
<builtin>: recipe for target 'first' failed
mingw32-make: ***[first] Error 2
I guess it's probably something really stupid, but I just can't figure out what I'm doing wrong. 我想这可能真是愚蠢,但我无法弄清楚自己在做什么错。 I really appreciate any help on this.
我对此表示感谢。 Thank you so much in advance.
提前非常感谢您。
So I went and tried it and... it works for me with MinGW-4.7.1 on a Win7 machine.... I'm wondering if make it picking up an environment variable or some such. 所以我去尝试了一下,...它在Win7机器上的MinGW-4.7.1上对我有用。...我想知道是否让它选择了一个环境变量或类似的变量。
Try verifiying the version of make and gcc are what you expect 尝试验证make和gcc的版本是否符合您的期望
mingw32-make -v gcc -v mingw32-gcc -v mingw32-make -v gcc -v mingw32-gcc -v
Also Try this makefile and see what happens. 还要尝试此makefile,看看会发生什么。
CC = mingw32-gcc
second.o: second.c second.h
$(CC) -c second.c
first.o: first.c
$(CC) -c first.c
first: first.o second.o
$(CC) first.o second.o -o first
Note convert spaces to tabs! 注意将空格转换为制表符!
And compile via 并通过编译
mingw32-make SHELL=cmd.exe first mingw32-make SHELL = cmd.exe首先
See what happens. 走着瞧吧。
