我是新手学习C而且我在Windows上(我想在Windows上学习)。
我在cygwin上安装了GCC,我正在使用 NetBeans IDE 。
来源:
#include <stdio.h>
main()
{
printf("Hello, world!\n");
return 0;
}
构建上述代码时出现错误:
"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make[1]: Entering directory `/cygdrive/g/VS Projects/Hello World'
"/usr/bin/make" -f nbproject/Makefile-Debug.mk dist/Debug/Cygwin_4.x-Windows/hello_world.exe

有没有简单的方法在Windows上学习C?(visual studio给了我错误,似乎主要是针对c ++,所以这不是一个选项)

问题可能出在您的gcc
或NetBeans配置
这里工作正常
// helloworld.c
#include <stdio.h>
main()
{
printf("Hello, world!\n");
return 0;
}
编译为myprog
$ gcc helloworld.c -o myprog
运行它
$ ./myprog
# => Hello, world!
答案 1 :(得分:1)
了解NetBeans的设置方式。失败的编译是:
gcc -o dist/Debug/Cygwin_4.x-Windows/hello_world \
build/Debug/Cygwin_4.x-Windows/helloworld.o \
build/Debug/Cygwin_4.x-Windows/main.o
那里有两个目标文件;一个看起来像helloworld.c
的{{1}}对象文件,另一个是文件main()
的对象文件,可能还包含main.c
程序。
重新定义构建规则,以便不将main()
链接到可执行文件中。

我知道这是一篇旧帖子,但您应该查看该项目的源文件。在那里,NetBeans默认生成2个main.c文件。擦除其中一个,只留下一个,然后再次尝试构建项目。
