First, check you did actually saveyour main.cfile(eclipse does not automatically save a source file)
首先，检查您是否确实保存了main.c文件（eclipse 不会自动保存源文件）
Then, check if your makefile is autogenerated or if you can write it yourself, as in this thread.
然后，检查您的 makefile 是否是自动生成的，或者您是否可以自己编写，就像在这个线程中一样。
CXXFLAGS = -O2 -g -Wall -fmessage-length=0
OBJS = main.o
LIBS =
TARGET = say.exe
$(TARGET): $(OBJS)
$(CXX) -o $(TARGET) $(OBJS) $(LIBS)
all: $(TARGET)
clean:
rm -f $(OBJS) $(TARGET)

You're building a Windows Application, but you don't have a WinMainthat is required by Windows applications.
您正在构建Windows Application，但您没有WinMainWindows 应用程序所需的。
Likely, you have a maininstead. You'll need to either change your project settings (to something along the lines of "Console Application"), or use WinMaininstead. You likely want the former.
很可能，你有一个main。您需要更改您的项目设置（更改为类似于“控制台应用程序”的内容），或者WinMain改为使用。你可能想要前者。
Note, WinMainis not standard. This is just the Windows linkage requirement.
注意，WinMain不是标准的。这只是 Windows 链接要求。

Make sure you got main at least. I fixed mine by providing a main function. I didn't have one when I was compiling. I am on windows.. seems by default it is trying to look for winmain.
确保你至少有主力。我通过提供一个主要功能来修复我的。我编译的时候没有。我在 Windows 上 .. 似乎默认情况下它正在尝试寻找 winmain。

I have tried many solutions nothing worked for me.Then I re-created the project and moved the .cppfile to projectname/src/.
我尝试了很多解决方案，但对我没有任何帮助。然后我重新创建了项目并将.cpp文件移动到projectname/src/.
Tested in Eclipse.
在 Eclipse 中测试。
