[Scons-users] Problem upgrading from 3.0.1 to 3.1.2

[Steve Hill (Wireless)]

Thanks. I have got to the bottom of it.

I am calling subst_list to get the list of paths (in $SOURCES, for instance) and assumed that returned strings. It actually returns a sequence of CmdStringHolder objects, which do not behave like strings when passed to os.path.splitdrive – in fact they result in an exception being thrown: ‘expected str, bytes or os.PathLike object, not CmdStringHolder’

Furthermore, it seems that, surprisingly, if an exception is thrown in the call, SCons doesn’t complain – it just ignores that the call even happened and simply stringifies the object instead. IMHO, this is questionable behaviour.

Anyway, I am now converting to string prior to calling splitdrive and all seems to be well…

Thanks again for your help,

S.

As a general note, it's not uncommon when converting from Py2 to Py3 to
run into things that give back an object reference instead of what you
were used to getting.

That said, for me at least, there's too much information omitted in your
snips to be able to tell more.
