如何设置CMAKE_AR的选项 [英] How to set the options for CMAKE_AR

问题描述

我使用cmake进行交叉编译，一切正常，但 CMAKE_AR 选项。

I'm do cross compiling with cmake and all is OK but the CMAKE_AR options.

我使用 set（CMAKE_AR $ {GCC_PATH} / dld）可设置 CMAKE_AR 。但我不知道如何设置它的选项。默认情况下，它使用选项 rc 创建归档。但我需要将其更改为 -X -r5 -o 。

I use set(CMAKE_AR ${GCC_PATH}/dld) to set CMAKE_AR. But I don't know how to set its option. On default, it use the options rc to create archive. But I need to change it to be -X -r5 -o. When use rc, it will complaint the file rc cannot be found.

如何解决？ p>

推荐答案

看起来像在创建归档的命令中的标志cr是硬编码的。没有办法只覆盖标志，你必须重写整个命令，像这样：

Looks like the flags "cr" are hardcoded in the command for creating an archive. There's no way to override just the flags, you have to rewrite the whole command, like this:

SET(CMAKE_CXX_ARCHIVE_CREATE "<CMAKE_AR> -X -r5 -o <TARGET> <LINK_FLAGS> <OBJECTS>")
SET(CMAKE_C_ARCHIVE_CREATE "<CMAKE_AR> -X -r5 -o <TARGET> <LINK_FLAGS> <OBJECTS>")

还有 CMAKE_C_ARCHIVE_APPEND （和CXX等价物），只将r标志传递给CMAKE_AR。您可能还需要更改那个。

There's also a CMAKE_C_ARCHIVE_APPEND (and CXX equivalent) that passes just the "r" flag to CMAKE_AR. You may have to change that one too.
