我正在为 ARM 使用 GCC(Red Suite 4 NXP)。我正在编译用于最终应用程序的静态库文件 (.a)。我需要配置项目,以便任何开发人员都可以生成完全相同的静态库输出。(这主要是为了让新开发人员可以验证他们的设置是否正确。)我有两个项目副本(来自 SVN 的两个结帐)。当我使用每个构建时,我注意到静态库 .a 输出文件中的一些绝对路径信息。这意味着 SVN 会检测到变化。我已经在使用 ar -D (确定性)选项。是否有任何其他选项可以删除路径信息?我尝试了 gcc -s 但这不起作用(看来这仅适用于最终可执行文件,而不是库)
我不知道绝对路径在 .a 中的位置/原因,但如果有人能指出我正确的方向,我可以提供更多信息。
我查看了 strip 实用程序手册页(尚未尝试过),这会删除此路径信息吗?
另外,我正在使用 Red Suite 来管理项目,所以我正在尝试以 Red Suite 的方式做事(并让它做它的事)。但是,如果我需要调整 gcc 或 ar 选项,我确实知道该怎么做。我只是不知道要更改什么选项。
这是构建控制台输出。这会导致我的项目的绝对路径包含在生成的 .a 中。这就是我要解决的问题。

更新:更多信息
我做了更多的挖掘,看起来完整的文件路径位于字符串常量的前面。.a 文件中的路径数据显示
C:/Users/my_user_name/Documents/My Project Verification build/src/touch/Touch.c.TouchIdleTimer
我在文件 Touch.c 中有一个字符串文字“TouchIdleTimer”。这是原因吗?我将如何删除路径部分,或者有可能吗?TIA
