[Request] Update Linux information in the wiki's "Compiling" page

I ran into some unexpected trouble building Snes9x for arm64 on a Linux install which only had the en_US.UTF-8 locale generated.

orangepi@orangepizero3:/home/opi/snes9x/gtk/build# ninja
[6/230] Generating de.gmo
FAILED: de.gmo /home/opi/snes9x/gtk/build/de.gmo
cd /home/opi/snes9x/gtk && GETTEXT_MSGFMT_EXECUTABLE-NOTFOUND -o /home/opi/snes9x/gtk/build/de.gmo po/de.po   /bin/sh: 1: GETTEXT_MSGFMT_EXECUTABLE-NOTFOUND: not found
[11/230] Building CXX object CMakeFiles/jma.dir/home/opi/snes9x/jma/lzmadec.cpp.o
ninja: build stopped: subcommand failed.   

I resolved this by:

1. Installing gettext with apt (possibly unnecessary? didn't verify if it builds without gettext)
2. Uncommenting de_DE.UTF-8, es_ES.UTF-8, fr_FR.UTF-8, ja_JP.UTF8 in /etc/locales.gen
3. Running locale-gen as root

After that, I could build with ninja normally and everything worked as expected.

Since one can't propose changes to the Wiki (https://github.com/snes9xgit/snes9x/wiki/Compiling), I'm requested the changes here.

Thank you!

You don't need the system locales. Installing the gettext executable alone is enough. The compile page lists "all dependencies of gtkmm" which includes gettext. I can't list all the dependencies down to the last library because it would be an enormous list, and some systems package things in different ways.

Thanks for the clarification! I misinterpreted that line as "whatever else the package manager installs with gtkmm", & I appreciate the correction.👍

you may also use https://github.com/sabotage-linux/gettext-tiny if the gnu gettext suite is too bloated for you... though i guess it would be even nicer if gettext use could be disabled entirely.
