如何设置CMAKE_AR的选项？ [英] How do I set the options for CMAKE_AR?

问题描述

我正在使用CMake进行交叉编译，一切正常，但是 CMAKE_AR 选项。

I'm doing cross compiling with CMake and all is OK but the CMAKE_AR options.

我使用设置（CMAKE_AR $ {GCC_PATH} / dld）设置 CMAKE_AR 。但是我不知道如何设置它的选项。默认情况下，它使用选项 rc 创建档案。但是我需要将其更改为 -X -r5 -o 。使用 rc 时，它将抱怨找不到文件 rc 。

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

我该如何解决？ / p>

推荐答案

看来， crs标志已硬编码在用于创建档案的命令中。无法仅覆盖标志；您必须像这样重写整个命令：

It looks like the flags "crs" 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>")

当数字为 CMAKE_C_ARCHIVE_APPEND （和CXX等价）时，的对象超过了命令行的最大值，它仅将 r标志传递给CMAKE_AR。您可能也需要更改它，请参见 https://cmake.org/ cmake / help / latest / variable / CMAKE_LANG_ARCHIVE_CREATE.html

There's also a CMAKE_C_ARCHIVE_APPEND (and CXX equivalent) used when the number of objects exceeds the command line maximum, it passes just the "r" flag to CMAKE_AR. You may have to change that one too, see https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_ARCHIVE_CREATE.html
