[Scons-users] Visual Studio : The process cannot access the file because it is being used by another process: '.sconsign.dblite'

[Pierre-Luc Boily]

Hello,

I know that there is not much VS users, but I give a try.  When I do a full
build within visual studio, I often get following error at random : "The
process cannot access the file because it is being used by another process:
'.sconsign.dblite'"

My theory is because Visual Studio launch 4 processes in parallel and it is
not supported by SCons being called like that.  I should instead compile one
project at a time with -j4.  Am I right?

thx
