我怎样才能Eclipse来索引code #IFDEF .... #ENDIF内 [英] How can I get Eclipse to index code inside #ifdef .... #endif

问题描述

我使用Eclipse来对一些C code工作，它不是索引条件编译块像这里面code：

I'm using eclipse to work on some c code and it is not indexing code inside conditional compilation blocks like this:

#ifdef USE_FEATURE_A
int feature_a(...) {
   some = code(here);
}
#endif

我怎样才能Eclipse来索引feature_a功能？

How can I get eclipse to index the feature_a function?

推荐答案

您可以告诉Eclipse的 USE_FEATURE_A 定义。打开你的项目属性，并转到C / C ++常规 - >路径和符号页，在符号选项卡中单击添加按钮，并把 USE_FEATURE_A 中名称费尔德，然后单击确定。

You could tell eclipse that USE_FEATURE_A is defined. Open your project properties and go to the "C/C++ General->Paths and Symbols" page, under the "Symbols" tab click the "Add" button and put USE_FEATURE_A in the name feild and click OK.

请注意：这将导致它无法索引任何的#else 双方你的preprocessor的东西......所以，除非他们都像在你的问题不能AFAIK，但如果是他们你是好。 （Eclipse中包含使用它来analyize您code以上所有的东西确实是基本相同，增加-DUSE_FEATURE_A到命令行让Eclipse的preprocessor将表现不同从一个在C preprocessor您编译器）

Note: this will cause it not to index any #else sides to your preprocessor stuff... so unless they are all like the one in question you can't AFAIK, but if they are they you're good. (Eclipse contains a C preprocessor that it uses to analyize your code all the stuff above does is essentially the same as adding -DUSE_FEATURE_A to your command line so Eclipse's preprocessor will behave differently from the one in your compiler)
