eclipse + cdt + mingw + windows error "undefined reference to `WinMain@16'" on build
提问by olamundo
I installed eclipse, cdt and mingw on my windows XP machine. added C:\MinGW\binto my PATH.
我在 Windows XP 机器上安装了 eclipse、cdt 和 mingw。添加C:\MinGW\bin到我的路径。
Created a new c++ project, with one file in it, test.c. the code in it:
创建了一个新的 c++ 项目，其中包含一个文件 test.c。其中的代码：
int main(){
int i=1;
}
Trying to build, I get the error:
/mingw/lib/libmingw32.a(main.o):main.c:(.text+0xd2): undefined reference to 'WinMain@16'
尝试构建，我收到错误：
/mingw/lib/libmingw32.a(main.o):main.c:(.text+0xd2): undefined reference to 'WinMain@16'
Notice it's not complaining about test.cbut rather about some main.cin one of mingw's libs.
请注意，它不是在抱怨，test.c而是main.c在 mingw 的库之一中抱怨。
What am I doing wrong?
我究竟做错了什么？

You need to save the .cfile first.
您需要先保存.c文件。

well, the solution was really weird, but I guess it would make sense to someone more proficient with CDT than me - My main() was inside a .c file. When I changed the suffix to be .cpp, it worked like a charm.
嗯，这个解决方案真的很奇怪，但我想这对于比我更精通 CDT 的人来说是有意义的 - 我的 main() 在一个 .c 文件中。当我将后缀更改为 .cpp 时，它就像一个魅力。
回答by Adam Mitz
main.o from libmingw32.a should not be searched by the linker because the undefined symbol _main from crt2.o is (should be) satisfied by the "int main()" which you wrote.
链接器不应搜索 libmingw32.a 中的 main.o，因为来自 crt2.o 的未定义符号 _main（应该）由您编写的“int main()”满足。
Please copy & paste the gcc command lines that cdt is executing.
请复制并粘贴 cdt 正在执行的 gcc 命令行。
