我正在ANSI-C Microsoft Windows [Version 10.0.14393]上使用msbuild版本Microsoft (R)-Buildmodul, Version 15.1.1012.6693
我可以使用下面显示的设置编译所有内容。
项目文件夹的结构如下：
- projectfolder
- a.vcxproj
- main.c
- main.h
- other.c
- other.h
- test.c
- test.h
的main.c
#include <stdio.h>
#include "main.h"
#include "test.h"
int main() {
printf("Hello World\n");
test_printf();
return 0;
}
main.h
#ifndef MAIN_H_
#define MAIN_H_
#endif // !MAIN_H_
other.c
#include "other.h"
#ifdef dummy
int some_number = 3;
#endif // dummy
other.h
#ifndef OTHER_H_
#define OTHER_H_
#define dummy
#ifdef dummy
extern int some_number;
#endif // dummy
#endif // OTHER_H_
test.c的
#include <stdio.h>
#include "test.h"
extern int test_printf(void) {
printf("Hello from test.c");
return 0;
}
test.h
#ifndef TEST_H_
#define TEST_H_
extern int test_printf(void);
#endif // !TEST_H_
构建脚本a.vcxproj看起来像这样（由Visual Studio 2017 Community生成，然后在编辑器中根据我的需要调整）：

**这个编译没有警告/ rrors到* .exe **
但是我想为每个生成的目标文件（main.obj，other.obj和test.obj）指定编译器允许在编译步骤中使用的源。
如果我将每个<ItemGroup>更改为此（每个生成* .obj文件，获取它应该用于编译步骤的* .c文件：
<ItemGroup>
<ClCompile Include="other.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
<ItemGroup>
<ClCompile Include="test.c;other.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
<ItemGroup>
<ClCompile Include="main.c;other.c;test.c"> <!-- !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -->
<DisableLanguageExtensions Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">true</DisableLanguageExtensions>
<CompileAs Condition="'$(Configuration)|$(Platform)'=='Release|Win32'">CompileAsC</CompileAs>
</ClCompile>
</ItemGroup>
然后我得到以下编译器和链接器警告：

在msbuild中是否有办法实现我喜欢做的事情：为每个源文件告诉msbuild它允许用于编译步骤的内容？
