[参考译文] PROCESSOR-SDK-AM64X：AM6442：TI RPMsg Char git package -运行最新 ARM GNU 编译器时出现的问题

Jim、您好！

我将与开发者讨论 v11 ARM gcc 编译器。 是否有特殊原因导致您无法使用 README 文件中记录的 v9.2 gcc 编译器？
https://git.ti.com/cgit/rpmsg/ti-rpmsg-char/tree/README

以下是我要在下一版本的 Academy 页面中添加的更新的示例编译输出、供您参考：

Build the Linux Userspace example for Linux RPMsg by following the steps
in the top-level README:

#. Download the git repo

#. Install GNU autoconf, GNU automake, GNU libtool, and v8 compiler as per the
   README

#. Perform the Build Steps as per the README

Sample build output on Ubuntu 22.04:

    ::

        :~/git/ti-rpmsg-char$ git status
        On branch master
        Your branch is up to date with 'origin/master'.

        Untracked files:
          (use "git add <file>..." to include in what will be committed)
                library/

        nothing added to commit but untracked files present (use "git add" to track)
        :~/git/ti-rpmsg-char$ git branch

        :~/git/ti-rpmsg-char$ git pull --rebase origin master

        :~/git/ti-rpmsg-char$ ./configure --host=aarch64-none-linux-gnu --prefix=/home/userName/git/ti-rpmsg-char/outputs
        ...
        -----------------------------------------------------------

        Thank you for installing the Linux ti-rpmsg-char package

        Installation directory prefix: '/home/userName/git/ti-rpmsg-char/outputs'.
        Compilation command: 'aarch64-none-linux-gnu-gcc -g -O2 '

        Now type 'make; sudo make install' to generate the program
        and install it to your system. sudo usage is optional and
        depends on the permissions of the prefix folder being used
        or installation.

        ------------------------------------------------------------

        :~/git/ti-rpmsg-char$ make
        ...

        :~/git/ti-rpmsg-char$ make install
        ...
        ----------------------------------------------------------------------
        Libraries have been installed in:
           /home/userName/git/ti-rpmsg-char/outputs/lib

        If you ever happen to want to link against installed libraries
        in a given directory, LIBDIR, you must either use libtool, and
        specify the full pathname of the library, or use the '-LLIBDIR'
        flag during linking and do at least one of the following:
           - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
             during execution
           - add LIBDIR to the 'LD_RUN_PATH' environment variable
             during linking
           - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
           - have your system administrator add LIBDIR to '/etc/ld.so.conf'

        See any operating system documentation about shared libraries for
        more information, such as the ld(1) and ld.so(8) manual pages.

尼克：

 我将单独回复构建输出。

wrt "无法使用 v9.2 gcc 编译器 "

我对 与跟上最新的 Gun ARM 交叉编译器和 Ubuntu 版本有关的支持问题表示同情。

我看到已经发布了 Ubuntu 24.04 LTS、并且针对 CCS 支持的 Ki 知道他需要提供支持(尽管我也知道 CCS v 13正在降低 Eclipse IDE、将 SDK 改装为 Theia 本身就是一项巨大的工作)。

我们可能需要跟上适用于制造流程的最新 GNU 工具。 我相信,一些较新的 GNU 工具版本(在之前的 e2e 中记录)可能会导致问题。

我应该期望应该访问 GNU v11 ARM gcc 编译器、因为并非所有旧版 gcc 工具都存在一些向前兼容性问题、因为出现了更新的 Ubuntu 2x.y LTS 发行版。

鉴于 AM6x 系列中的内核混合、从交叉兼容性编译问题来看、我将继续介绍更新的 gcc 工具集。

[我还记得如何在90年代的 TI ASP ASIC 日之前使 Solaris/SunOS 发布的 Unix 工具恢复正常。   即使在 Linux 环境中、某些版本控制方案也会随着更改而重复]

请让开发团队考虑推进 gcc 工具版本。

谢谢

吉姆·穆罗卡

Jim、您好！

我已与开发人员讨论并提出 更新至最新 gcc 编译器的要求。 目前，我没有任何发展商方面的承诺或时间表，但它是在系统中。
