c - 如何在 Visual C++ Express 2010 中编译 C 代码

Question

我正在尝试在 VS C++ Express 2010 中编译 C 代码，但我得到以下错误跟踪:

1>------ Build started: Project: test4, Configuration: Release Win32 ------
1>cl : Command line error D8045: cannot compile C file 'test4.c' with the /clr option
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

当我尝试使用 cpp 扩展进行编译时，我得到了这个错误跟踪:

1>------ Build started: Project: test4, Configuration: Release Win32 ------
1>  test4.cpp
1>c:\documents and settings\rkelly1\desktop\io\test4\test4\pt_ioctl.c(86): error C2664: 'CreateFileW' : cannot convert parameter 1 from 'const char [13]' to 'LPCWSTR'

Answer 1

/clr 表示使用 .Net 运行时 - 而不是 c 语言运行时!

只要调用文件 .c 就可以了，有一个标志可以阻止你使用任何 c++ 特性。

转到属性 -> c/c++ -> 高级 -> 编译为并选择“c”
