I think it is because of using --disable-nls
which is used by default for configuring GCC: https://github.com/niXman/mingw-builds/blob/develop/scripts/gcc-13.2.0.sh#L122
from the man:
--enable-nls
--disable-nls
The --enable-nls option enables Native Language Support (NLS), which lets GCC output diagnostics in languages other than American English. Native Language Support is enabled by default if not doing a canadian cross build. The --disable-nls option disables NLS.
Note that this functionality requires either libintl (provided by GNU gettext) or C standard library that contains support for gettext (such as the GNU C Library). See [–with-included-gettext](https://gcc.gnu.org/install/configure.html#with-included-gettext) for more information on the conditions required to get gettext support.
I did the following tests and all failed: 1、file:"gcc-13.2.0.sh", replace "--disable-nls" with "--enable-nls". (https://github.com/niXman/mingw-builds/commit/dd9a546a3d595c26fcd73610a600ace897d02015)
2、file:"gcc-13.2.0.sh", add: --with-libintl-prefix=/usr/lib --with-libintl-type=autostaticshared --with-included-gettext (https://github.com/niXman/mingw-builds/commit/247aa04640049b7c50efdedf5f20eb9ab60e4d0f)
3、revise "gcc\intl.cc" in "gcc-13.2.0.tar.xz" and replace "--disable-nls" with "--enable-nls" in all file. (https://github.com/niXman/mingw-builds/commit/2ecf0108ca70f60375556e1c73a67281d7ff53a5)

@yuanpeirong could you please just replace --disable-nls
with --enable-nls
here: https://github.com/niXman/mingw-builds/blob/develop/scripts/gcc-13.2.0.sh#L122
and rebuild the 13.2.0, and report the result back?
my Test1 is this:file:"gcc-13.2.0.sh", replace "--disable-nls" with "--enable-nls". https://github.com/niXman/mingw-builds/commit/dd9a546a3d595c26fcd73610a600ace897d02015
but it is failed.
but it is failed.
what does this mean? please provide the error report.
For example,this is hello.cpp
file
//hello.cpp
#include <iostream>
using namespace std;
int main(){
cout1 << "Hello World." << endl;
return 0;
}
In Linux:g++ hello.cpp -o hello
It will output with my UI language set as Chinese,like this
错误:‘cout1’在此作用域中尚未声明
but in Windows:
I just replace --disable-nls
with --enable-nls
here: https://github.com/niXman/mingw-builds/blob/develop/scripts/gcc-13.2.0.sh#L122
and rebuild the 13.2.0
I also g++ hello.cpp -o hello.exe
It is not will output in my UI language set as Chinese.
It is also output
error: 'cout1' was not declared in this scope
@yuanpeirong It's not clear from your first message that the compiler was built successfully =)
then you need to inspect the GCC configuration log file. and, also please put it here.
this is the file:http://www.yuanpeirong.com/gcc/x86_64-13.2.0-release-posix-seh-ucrt-rt_v11-rev0.7z I just replace --disable-nls with --enable-nls here: https://github.com/niXman/mingw-builds/blob/develop/scripts/gcc-13.2.0.sh#L122 and rebuild the 13.2.0
ok, then please provide the GCC configuration log file.
Please check it out: build-info.txt Thank you.
this is not configuration log, but the configuration RESUME file.
configuration log file is what is generated by the configure
configuration script, which is part of the GCC source code.
according to the provided RESUME file, I think it should be placed in /c/buildroot/gcc/
... please provide me the list of entries in the /c/buildroot
directory.
it is build in Github Actions https://github.com/yuanpeirong/mingw-builds/actions/runs/7384217528/job/20086722002 x86_64 _posix_seh ucrt.txt
unfortunately I don't know how to view the required file on Github Actions...
could you help me to rebuild it ?
please read the README: https://github.com/niXman/mingw-builds/blob/develop/README.md
it looks actual.
We have a build with --enable-nls . On Windows 7 of Chinese version, we got the following results:
Running command "gcc" or "gcc -v" or "gcc --help", the output message is in Chinese now. For example: d:\mingw-zh_cn\mingw64>gcc gcc: 致命错误:没有输入文件
Compiling source file, the output message is still in English. For example: d:\mingw-zh_cn\mingw64>gcc hello.cpp hello.cpp: In function 'int main()': hello.cpp:7:9: error: 'cout1' was not declared in this scope 7 | cout1 << "Hello, World!" << endl; | ^~~~~
What we need to do in order to make the output compiling message in Chinese?
hmm... I will ask on GCC mailing list...
@anbangli
please read: https://gcc.gnu.org/pipermail/gcc-help/2024-January/143170.html
please comment the questions at the link.
I have just read LIU Hao's comment in https://gcc.gnu.org/pipermail/gcc-help/2024-January/143172.html . I guess that we have got the reason as following.
For command "gcc -v" and "gcc --help", the message is outputed by program bin/gcc.exe. According to relative path "../share/locales/zh_CN/LC_MESSAGES/", the program can find zh_CN.po correctly.
But in compiling, the compiling message is outputed by program libexec\gcc\x86_64-w64-mingw32\11.2.0\cc1plus.exe, the program can not correctly find zh_CN.po according to relative path "../share/locales/zh_CN/LC_MESSAGES/".
But in compiling, the compiling message is outputed by program libexec\gcc\x86_64-w64-mingw32\11.2.0\cc1plus.exe, the program can not correctly find zh_CN.po according to relative path "../share/locales/zh_CN/LC_MESSAGES/".
That was only a presumption. Please try copying the locale directory so it may be found, and see whether it solves the issue for you.

Good advice.
I copied directory share/locales/zh_CN/LC_MESSAGES/ to
libexec/gcc/x86_64-w64-mingw32/11.2.0/share/locales/zh_CN/LC_MESSAGES/,
and got error message in Chinese:
d:\mingw-zh_cn\mingw64>gcc hello.cpp hello.cpp: In function ‘int main()’: hello.cpp:7:9: 错误:‘cout1’在此作用域中尚未声明 7 | cout1 << "Hello, World!" << endl; | ^~~~~
So, my presumption is confirmed.
I believe this has something to do with https://github.com/gcc-mirror/gcc/blob/4d31d6606201b339825c370c2e1969b2dcd17f39/libcpp/init.cc#L186.
It is practically bad to supply a relative path (second argument) to bindtextdomain()
; maybe it is possible to get the absolute path of the current executable with GetModuleFileNameW()
, then replace \lib\gcc\...
up to the end with the locale dir, then feed the result to wbindtextdomain()
.
I have got an article in which fixed the problem: https://blog.csdn.net/hackpascal/article/details/15222083
@lhmouse , would you please merge the upper source code to GCC?
That code needs polishing a bit. For example, wide-char functions should be preferred to ANSI ones.
@anbangli @lhmouse guys, any progress on it?
.. almost forgot this one. This is gonna be a bit complex and requires some time to look into.
If copying the locale directory works, I think it will be the safest solution.
While it is possible to find the locale directory by replacing the executable name in <prefix>/lib/gcc/x86_64-w64-mingw32/11.2.0/cc1plus.exe
with ../../../../share/locales
, as the code is shared by all gcc executables, for gcc.exe it would run out of <prefix>
. It's like accessing past the end of a buffer, which does not necessarily cause a crash, but it's not good anyway.
I use both Windows and Linux with UI language set as Chinese. I noticed that GCC's output information is Chinese on Linux, but is English on Windows.
Is the difference came from localization options in building?
I hope GCC's output information is Chinese on Windows too.
