some difficulties building on ng branch with clang

[laurentoget]

to start with i must be doing something wrong, but when i git checkout the ng branch, i had to fix some of the submodules that did not get recursively checked when i switched branch. once i got over that, the build failed with:

WARNING: 'makeinfo' is missing on your system.
         You should only need it if you modified a '.texi' file, or
         any other file indirectly affecting the aspect of the manual.
         You might want to install the Texinfo package:
         <https://www.gnu.org/software/texinfo/>
         The spurious makeinfo call might also be the consequence of
         using a buggy 'make' (AIX, DU, IRIX), in which case you might
         want to install GNU make:

my clang is

laurent@wilson:~/src/mcpe/mcpelauncher/build$ clang --version
clang version 9.0.0-2 (tags/RELEASE_900/final)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
laurent@wilson:~/src/mcpe/mcpelauncher/build$ 

thanks for the great work - let me know if there is anything i can do to help troubleshoot

[ChristopherHX]

I guess install makeinfo.
If you just want to run ng, please try the appimage https://github.com/ChristopherHX/linux-packaging-scripts/releases/tag/ng.appimage
Build script still not moved back to minecraft-linux

[laurentoget]

Thanks... the appimage is failing on 1.14.60.5 with

[ChristopherHX]

I don't think that LD_PRELOAD=libgtk3-nocsd.so.0 is a good idea

Please follow
ChristopherHX#72 (comment)

The unsupported launcher extracts newer game versions in a wrong way, therefore please redownload it after deleting it in Settings
Note, you are not testing ng but that is fine.
Please update the launcher (The launcher should tell you to update)
