0.020 W Selected invalid language "", defauting to "en_US"

[harry2290]

I met the following message when I start MultiMC on my CentOS7(3.10.0-862.14.4.el7.x86_64). I used mmc-stable-lin64.tar.gz package.

• 0.020 W Selected invalid language "", defaulting to "en_US"

I think I have config the right LANG.

$ echo $LANG
en_US.UTF-8
$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

$ locale -a|grep en_US
en_US
en_US.iso88591
en_US.iso885915
en_US.utf8

Is there anything that I missed?

any helps are appreciated. Thanks in advance.

I don't known if MultiMC also need X11 or Desktop? Could you please give me a checklist for running MultiMC?

[harry2290]

By the way, I set LANGUAGE in /etc/profile
LANGUAGE="en_US.utf8"

echo $LANGUAGE
en_US.utf8

$ sh MultiMC -V
Launcher Dir: /opt/MultiMC

Please make an investigation about my problem.
I am curious how the MultiMC found the language is invalid?

[phit]

pretty sure that message is coming from Qt and not MultiMC

[harry2290]

Hi Phit,
Thanks for your response.
Could you give some clause to fix this Qt's exception?

Regards,
Harry

[phit]

it's just a warning, is it causing you any actual issues?

[harry2290]

It caused MultiMC hang up, and can not startup.
So I would like to known which version of Qt you test on? Should I make any configuration after installing qt5-atbase?
By the way, I used qt5 RPM package (qt5-qtbase-5.9.7-5.el7_9.x86_64.rpm) , download from the following url:
https://pkgs.org/download/qt5-qtbase
Is this rpm package ok?
Could you provide a suitable qt5 package download url ?

Thanks in advance

[phit]

can you post your actual MultiMC-0.log file, MultiMC is build with various versions depending on OS, anything from 5.6 to 5.15 should work ok

are you using https://copr.fedorainfracloud.org/coprs/kb1000/multimc/ ?

[harry2290]

I download MultiMC from the following url:
https://files.multimc.org/downloads/mmc-stable-lin64.tar.gz

Attachment is MultiMC-0.log.

I have browsed the url that you provide. There is no package for Centos 7.
MultiMC-0.log

[harry2290]

I choosed Centos-stream 8 release and installed MultiMC from the repo that you provided successfully on my CentOS7.

I would like to known how to run MultiMC after installation.

Thanks in advance
