[Scons-users] Build fails due to MissingConfiguration error

Thu Sep 21 18:55:32 EDT 2023

Hi all, sending an email to this list before raising an issue on github as
advised by the docs.

I just tried to build the Godot engine by following their instructions:
https://docs.godotengine.org/en/stable/contributing/development/compiling/compiling_for_windows.html
https://docs.godotengine.org/en/stable/contributing/development/configuring_an_ide/visual_studio.html

In my cmd window I ran these commands from the Godot directory as
instructed (also enabled more debug info):
set SCONS_MSCOMMON_DEBUG=-
set env=Environment(MSVC_VERSION='14.2',TARGET_ARCH='x86_64')
scons platform=windows vsproj=yes dev_build=yes

But the build would always fail at this step:

SCons tries to find all existing installations of VC, and for most of the
ones it can't find it (correctly) moves on, but for some reason when
finding VC 10.0 it returns the  MissingConfiguration error.

I was able to fix this by removing the line raising the error and instead
returning None, in the function find_vc_pdir in vc.py

debug('reg says dir is %s, but it does not exist. (ignoring)', comps)
return None
#raise MissingConfiguration("registry dir {} not found on the
filesystem".format(comps))

My build then completed successfully. I guess this must be a bug in SCons,
because the attempt to find the missing VC 10.0 installation *should *return
the same as the attempts to find the other missing VC installations.

Si.
