Problems with directory containing Chinese characters

[anbangli]

I am an Chinese programmer, and I found that the current MinGW-w64 versions (11.2, 12.2, 13.2, released by niXman or winlibs) have two problems with directories which contain Chinese characters.

Normally, MinGW-w64 is installed in directory "C:\MinGW64". If my program "hello.cpp" saved in directory "C:\myprogs", then following compiling command will success:

C:\MinGW64\bin\g++.exe "C:\myprogs\hello.cpp" -o "C:\myprogs\hello.exe" -Wall -Wextra -pipe -I"C:\MinGW64\include" -I"C:\MinGW64\x86_64-w64-mingw32\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include\c++" -L"C:\MinGW64\lib" -L"C:\MinGW64\x86_64-w64-mingw32\lib" -static-libstdc++ -static-libgcc

Problem 1: if the path of my programs contains Chinese characters, then compilation will fail.
For example, MinGW-w64 is installed in normal directory "C:\MinGW64", my program "hello.cpp" saved in directory "C:\我的程序"，I typed the following compiling command::

C:\MinGW64\bin\g++.exe "C:\我的程序\hello.cpp" -o "C:\我的程序\hello.exe" -Wall -Wextra -pipe -I"C:\MinGW64\include" -I"C:\MinGW64\x86_64-w64-mingw32\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include\c++" -L"C:\MinGW64\lib" -L"C:\MinGW64\x86_64-w64-mingw32\lib" -static-libstdc++ -static-libgcc

The compilation command will give message:
cc1plus.exe: fatal error: C:\鎕ello.cpp: No such file or directory
compilation terminated.

Apparently, path "C:\我的程序\hello.cpp" is not correctly processed, it was processed as "C:\鎕ello.cpp".

If I rename the program file "hello.cpp" to "测试hello.cpp", and typed the following compiling command:
C:\MinGW64\bin\g++.exe "C:\我的程序\测试hello.cpp" -o "C:\我的程序\测试hello.exe" -Wall -Wextra -pipe -I"C:\MinGW64\include" -I"C:\MinGW64\x86_64-w64-mingw32\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include" -I"C:\MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include\c++" -L"C:\MinGW64\lib" -L"C:\MinGW64\x86_64-w64-mingw32\lib" -static-libstdc++ -static-libgcc

The compilation command will give message:
C:\骀礶llo.cpp: In function 'int main()':
C:\骀礶llo.cpp:7:36: error: expected ';' before 'return'
7 | cout << "Hello, World!" << endl
| ^
| ;
8 |
9 | return 0;

Apparently, path "C:\我的程序\测试hello.cpp" is not correctly processed, it was processed as "C:\骀礶llo.cpp".

Problem 2: If the installation directory of MinGW-w64 contains Chinese Characters, then compilation will fail.
For example, MinGW-w64 is installed in directory "C:\编译器MinGW64" which contains Chinese characters, one tried to compile program "C:\myprogs\hello.cpp" with the following command:

C:\编译器MinGW64\bin\g++.exe "C:\myprogs\hello.cpp" -o "C:\编译器hello.exe" -Wall -Wextra -pipe -I"C:\编译器MinGW64\include" -I"C:\编译器MinGW64\x86_64-w64-mingw32\include" -I"C:\编译器MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include" -I"C:\编译器MinGW64\lib\gcc\x86_64-w64-mingw32\13.2.0\include\c++" -L"C:\编译器MinGW64\lib" -L"C:\编译器MinGW64\x86_64-w64-mingw32\lib" -static-libstdc++ -static-libgcc

The compilation will fail, and the output message is:

It seems that the Chinese characters "编译器" are ignored in some internal stage.

Please check the two problems. Thanks.

BTW, MinGW-w64 8.1.0 does not have such problems.

hi,

looks like the same issue?: niXman/mingw-builds#649

[anbangli]

"Problem 1" in this issue seems to be the same with "1st bug" in that issue.

But "Problem 2" seems not concerned in that issue.

[niXman]

@anbangli it seems according to the answer (niXman/mingw-builds#649 (comment)) the question is solved?

if so - please close the issue.

best!
