防止gcc搜索当前目录“-I-”选项包括搜索路径 [英] prevent gcc from searching the current dir "-I-" option on include search path

问题描述

我们的开发环境大量使用了具有本地修改的头文件的目录，编译器而不是提交的存储库版本。

Our dev environment makes heavy use of directories with locally modified headers that should be seen by the compiler instead of the "committed" "repository" versions.

A包括头文件B，gcc在同一目录A中查找B，并且不遵守seach路径。
所以我们使用gcc上的 -I - 选项来阻止。 Gcc将严格遵循include-path的层次结构。
与gcc4一样， -I - 选项已弃用，并由 -iqoute 重新定义。
我不知道如何使用 -iquote 选项获得相同的行为，因为我认为它缺乏禁用搜索的副作用current目录。

If header A includes header B, gcc looks for B in the same directory A was in and does not obey the seach path. So we used the -I- option on gcc to prevent that. Gcc will strictly follow the hierarchy of the include-path then. As with gcc4 the -I- option is deprecated and repaced by -iqoute. I can't figure out how to get the same behaviour with the -iquote option because I think it is lacking the side-effect of disabling the search in the "current" directory.

请参阅 http://gcc.gnu.org/onlinedocs/cpp/Invocation.html#Invocation

任何想法如何实现相同的行为？ / p>

Any ideas how to achieve the same behaviour?

推荐答案

AFAIK，没有其他方法来停用你抱怨的行为，除了使用 #include< foo.h> 而不是 #includefoo.h。

AFAIK, there is no other way to desactivate the behaviour you are complaining about other than using the form #include <foo.h> instead of #include "foo.h" in your code.

ISTR，但是我没有找到参考，不提供另一种机制的原因是： -I - 使用 #includefoo.h的形式确保它们获得自己的内部头文件 foo.h 和使用 -I - 在某些情况下破坏了它们，如果别人碰巧在搜索路径上有类似名称的文件。

ISTR, but I've failed to find a reference, that the rationale for deprecating -I- without providing another mechanism for that aspect is that libraries commonly use the form #include "foo.h" to ensure they get their own internal header file foo.h and the use of -I- broke them in some cases if someone else happened to have a file similarly named earlier on the search path.
