Compiling...
ex11aView.cpp
d:\myfiles\projects\ex11a\ex11aview.cpp(4) : fatal error C1083: Cannot open precompiled header file: 'Debug/ex11a.pch ': No such file or directory
Error executing cl.exe.

ex11aView.obj - 1 error(s), 0 warning(s)


[解决办法]
现在退出VS,然后删掉所有的pch文件,然后重新编译.

或者是在工程设置里面,把预编译那一项关掉
[解决办法]
预编译头文件错误, 可以不使用它.
Project -> Settings -> C/C++
在 Category 中选择 Procompiled Headers 然后选择其中的 "Not using precompiled headers "
[解决办法]
偶上次内容不足时也出现了这个问题，关掉些程序就可以， 看看你是不是也是这个原因
[解决办法]
上面说错了，是内存不足
[解决办法]
Fatal Error C1083
Cannot open filetype file: 'file ': message

An error occurred opening the specified file.

Tips

This error can occur if the file, subdirectory, or disk on which it resides is read-only. In this case, make the file writable or move the file to a writable disk. See your operating system documentation for information on removing the read-only attribute from a file.


This error may be caused by not having enough file handles. Close some open applications and recompile.


Trying to open a file or directory for which you do not have permission can cause this error. Move the file to a directory where you do have access privileges, or ask your network administrator to grant you access to the file.


If an include file could not be opened, check that the INCLUDE environment variable is set correctly and that the name of the file is spelled correctly.


Using double quotation marks around a complete path specification in a #include directive causes the standard directories to NOT be searched. See The #include Directive in the Preprocessor Reference for more information.
