vxworks解决注释不匹配问题

vxworks默认的注释类型是“/*。。。。。*/”在使用C++类型的注释“//”，就有可能报错。 一种方法是移除-ansi开关。可是怎么移除呢？对许多对编译器不太了解的人可能看了FAQ了不知道怎么办。下面具体讲解：

在vxworks的工程里有build这个选项，字体变黑的就是你选的编译类型以default为例，双击default（默认的），在c/c++compiler和assember里将-ansi去掉，然后再OK！
下面来自预编译器文档`-lang-c', `-lang-c89', `-lang-c++'
`-lang-objc', `-lang-objc++'
Specify the source language. `-lang-c' is the default; it allows recognition of C++
comments (comments that begin with `//' and end at end of line), since this is a common
feature and it will most likely be in the next C standard. `-lang-c89' disables recognition
of C++ comments. `-lang-c++' handles C++ comment syntax and includes extra default include
directories for C++. `-lang-objc' enables the Objective C `#import' directive. `-lang-objc++'
enables both C++ and Objective C extensions. These options are generated by the compiler
driver gcc, but not passed from the `gcc' command line unless you use the driver's `-Wp'
option .

其实如果要跟深入了解，可以看看GNU方面的资料

另外，在.cpp格式的文件中可以使用//做注释，编译不会报错。
