It seems the issue is related to gcc printing out non-English characters. We've had a lot of trouble reproducing this behavior in house and therefore have been unable to put together a reliable fix.

mybe it is

c/c++ extesion has the same problem!

[ChristianS99]

Invoking gcc with LANG="" environment variable could fix this until it can be properly fixed.

At least startting code with empty LANG works around this.

[bobbrow]

@ChristianS99 how did you set up your work environment prior to this? We still haven't been able to get a repro for this language issue. I tried setting all the env variables like LANG, etc but gcc still prints English messages for me. I'm trying to add Spanish as a language to my Ubuntu installation, but it doesn't seem to be working.

[ChristianS99]

I did nothing special, I'm on Gentoo Linux and have nls (native language support) enabled.
with this, a few mo-files get installed and used.
Maybe Ubuntu doesn't install translations for gcc (on purpose?).
The translation files I have are cpplib.mo, gcc.mo, libstdc++.mo. Maybe you can search if you find them, but I would guess that Ubuntu omits them.

can you check your gcc -v output for [enable|disable]-nls? If it is enabled, and just the language files aren't installed, it should be enough, to get the files (I could provide them maybe) to the right place.
If it is disabled at all, you could compile gcc yourself (and enable nls) or use a different distribution that has gcc with nls

[flying-sheep]

When compiling, I get

[rollbar] Ausnahmefehler: Unbehandelte Promise-Ablehnung: build Error: Unknown diagnostic severity level: Warnung {}

“Warnung” is German for “Warning”.

You really should invoke gcc with LANG set to some defined value.

[listenerri]

any progress on this?

[skoehler]

Seeing the same error message over and over again:
[rollbar] Ausnahmefehler: Unbehandelte Promise-Ablehnung: build Error: Unknown diagnostic severity level: Warnung {}

I don't understand why this is such a big issue. On German systems, programs prints German messages. On Spanish systems, programs print Spanish messages, etc. - Why wasn't this anticipated a long time ago?

Until you have finished supporting all languages, would you please be so kind and call cmake and gcc with LANG=C on systems with languages that you do not support? There is also the LC_* family of variables that you will need to control. This is just the easiest way to deliver something to an international audience.

[flying-sheep]

Until you have finished supporting all languages

You misunderstood the issue. When parsing output, one doesn’t need to support more than one language, because you’re treating the output as machine-readable message, not one for human consumption. Therefore LANG=C is the correct thing to do forever: You tell the software to give you the message it displays in the source code, which hopefully shouldn’t change.
