GCC Localization Unsuccessful

[zsd2024]

I attempted to localize GCC in the MSYS2 environment but was unsuccessful. I have followed these steps:

1. Generate the gcc.mo file using the gettext tool:

   msgfmt -o gcc.mo gcc.po
   

2. Place the gcc.mo file in the /usr/share/locale/zh_CN/LC_MESSAGES/ directory:

   mkdir -p /usr/share/locale/zh_CN/LC_MESSAGES/
   cp gcc.mo /usr/share/locale/zh_CN/LC_MESSAGES/
   

3. Set the environment variables:

   export LANG=zh_CN.UTF-8
   export LC_ALL=zh_CN.UTF-8
   

4. Restart the terminal and run GCC, but the output is still in English.

Environment Information:

• Operating System: Windows 11
• MSYS2 Version: Latest
• GCC Version: 14.2.0

Tried Solutions:

• Ensure the gettext-devel package is installed:

  pacman -S gettext-devel
  

Error Messages or Logs: No specific error messages, but the GCC output is still in English.

What else should I check or try?

This is what I get here, without any changes:

$ LANG=zh_CN.utf8 gcc
gcc: 致命错误：没有输入文件
编译中断。

4. Restart the terminal and run GCC, but the output is still in English.

Are you persisting the changed locale settings somewhere? Otherwise I don't see how that would work with a fresh environment.

4. 重新启动终端并运行 GCC，但输出仍为英文。

您是否在某处保留了更改的区域设置？否则，我看不出这在新鲜环境中如何工作。

Apologies, but I didn't quite catch your question. Could you please rephrase it in English? I'm having trouble understanding your statement: "您是否在某处保留了更改的区域设置？否则，我看不出这在新鲜环境中如何工作。"

However, when I run this command, I get:

$ LANG=zh_CN.utf8 gcc
gcc.exe: fatal error: no input files
compilation terminated.

This is my installation folder directory tree: tree.txt

@lazka Additionally, the system I am using is Windows 11 instead of Windows 10, and what I actually want to localize is g++.

~~Did you install MSYS2 to a non-default directory?~~

export 仅是指定此处定义的环境变量会继承给子进程。如果你重启了终端，原来定义的环境变量就没有了。

你可以在 mintty 的 Text 设置中设定使用的语言，这会影响所有 mintty 内的进程。你也可以在系统设置里设定 LANG 环境变量，这会影响所有的进程，包括那些从 cmd 或者 PowerShell 中启动的。

However, when I run this command, I get:

$ LANG=zh_CN.utf8 gcc
gcc.exe: fatal error: no input files
compilation terminated.

which gcc 输出的是什么？目前只有 /usr/bin/gcc 支持本地化。

Yes, I installed it in the D:\Greens\msys2 directory.

You can try building GCC yourself, but the locale directory is quirky to setup. I don't remember much of the details. It's likely that only messages from gcc.exe are localized; those from a compiler e.g. cc1.exe or cc1plus.exe are not. The bindtextdomain() function assumes executables are placed in bin directory and looks for locale files via a relative path (..\share\locale I suspect). You will need to copy locale files to a location where they can be found by this relative path.

Maybe, if we want to do the same.

It's not working, the output is invalid encoding:

$ ./riscv64-juntian-elf-cc.exe
riscv64-juntian-elf-cc.exe: 鑷村懡閿欒锛?[m娌℃湁杈撳叆鏂囦欢

缂栬瘧涓柇銆?

This is for mingw, not for msys2.

Maybe it's comes from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=108865

Because --enable-win32-utf8-manifest is by default for windows 11,

Yeah, I am verified it, when use --disable-win32-utf8-manifest, it working.
