Hi,
new version 4.1-1 of
This version of make introduces a regression in VPATH handling.
Bash uses VPATH = .:/path/to/sources
to specify a two-directory VPATH. Technically, the .: is redundant
(because make will automatically search the current directory before
resorting to VPATH rules), but that hasn't stopped bash from using it
anyways. (Most automake-based packages only use a one-directory VPATH
designation; but bash doesn't use automake)
The old version of make properly handled this as two directories; but
the new version of make is apparently treating it as a drive letter
directive and failing to look in /path/to/sources.
If I change bash to emit:
VPATH = . /path/to/sources
then things work again. Likewise if I change it to omit the redundant
leading '.:'. So I can work around the regression in the meantime.
I'm reporting it here rather than upstream, as drive letter handling may
be cygwin-specific; but you may decide that the regression is upstream.
Meanwhile, I'll also report to the bash list that use of .: is no
longer portable in VPATH designations.
make 4.0 and 4.1 are using upstream sources with no patches.
For what I understood it was the same on 3.8.x version
managed by CGF.
I will look on it
Regards
Marco
