C预处理器定义没有被Cedet/Semantic考虑

Question

我试图在我的Linux内核开发项目中使用Emacs作为IDE。因此，我安装了CEDET和GNU Global (Gtag)，没有任何问题。

当我打开属于我的Linux内核源代码文件夹的C源代码时，会自动检测到linux项目。正确突出显示函数、变量、标头和其他关键字。

通过~/..emacs文件，我配置了语义的代码完成和intellisense。所以当我按C键时，代码完成菜单就会出现，我可以选择需要什么。

问题是当我使用预处理器定义时，intellisense系统显示当前位置上的菜单，但在调用(C-)时没有检测到正确的内容。即使我关闭并重新启动emacs，也会复制相同的行为。

测试代码是：

//--------------------------------------

typedef struct
{
     int p1;

        #ifdef __KERNEL__

            int p2;

        #endif

        #ifdef USE1

             char p3;

          #endif

#ifdef __LINUX_ARM_ARCH__

   int p4;

#endif

}OBJ;

OBJ g_obj;

//--------------------------------------

LINUX_ARM_ARCH内核、USE1和USE1已经定义如下：

__KERNEL__ : (add-to-list 'semantic-lex-c-preprocessor-symbol-map '("__KERNEL__" . "")) in .emacs
USE1 : defined in a header file included by the current C source file.
__LINUX_ARM_ARCH__ : (add-to-list 'semantic-lex-c-preprocessor-symbol-file "/home/abdellatif/kernel/include/generated/autoconf.h") in .emacs

在.emacs文件中，我还添加了GCC交叉编译器(GCC用于ARM)所需的所有必需的包含和定义，以构建内核项目。

我也试图强迫语义使用GCC交叉编译器命令行来代替GCC对系统进行正确的预处理，但还没有找到如何实现的方法。

“M语义-c-描述-环境”命令显示正确的包含路径和定义(在.emacs中设置)。但GCC所界定的制度也被列举出来。

.emacs文件和软件版本如下所示。

欢迎任何帮助或暗示:)最好的问候

1. 您应该从主线获得cedet：

bzr://cedet.bzr.sourceforge.net/bzrroot/cedet/code/trunk/

对于处理recently.

• After的预处理程序有几个修复程序，可以更改语义-lex-c-预处理-符号-文件列表以及类似的内容，您应该删除语义缓存，并允许它从头开始重新创建它。
