Hi,

The problem is that $Config{libpth} places whatever is specified in
EXTRALIBDIRS (in GNUmakefile) inside double quotes:

C:\_32>perl -V:libpth
libpth='C:\_32\gcc-mingw-530\mingw32\lib
"C:\_32\gcc-mingw-530\mingw32\i686-w64-mingw32\lib
C:\_32\msys_530\1.0\local\lib
C:\_32\gcc-mingw-530\mingw32\lib\gcc\i686-w64-mingw32\5.3.0"';

Consequently, any library that's in one of those EXTRALIBDIRS directories
won't be found when EXTRALIBDIRS specifies more than one location.
Perhaps the double quotes don't matter if EXTRALIBDIRS specifies only one
location - that's rather moot, and I haven't checked.

The solution is to remove the 2 double quotes from libpth - which I've done
by editing Config.pm and Config_heavy.pl.

However, I haven't yet gone looking for the source that created those 2
double quotes in the first place.
If someone points me to a good place to start looking I might be able to
help out with that.

My 'perl -V' is given below (though my 3 other configurations of 5.25.2 are
affected in the same way).

Cheers,
Rob

As a starting point, do you know whether you have this problem on 5.24.0 on this machine?

Thank you very much.

No such problem with 5.24.0. (I should have thought to mention that.)

This is the first time I've built 5.25.x, and this is the first time I've
struck this issue.

I don't see the relationship ... though please don't think that I'm
asserting there isn't one.

When I diff the GNUmakefile that shipped with 5.24.0 against the GNUmakefile
that ships with 5.25.2, the only differences that are presented are:

1) differences in version number (ie 5.24.0 has become 5.25.2, 524 has
become 525 and 5240 has become 5252);
2) the inclusion in 5.25.2 of the line:
-if exist $(LIBDIR)\Test2 rmdir /s /q $(LIBDIR)\Test

Incidentally, I would have expected that should be:
-if exist $(LIBDIR)\Test2 rmdir /s /q $(LIBDIR)\Test2

I don't see anything that would be involved in the change of behaviour (from
5.24.0 to 5.25.2) re the setting of $Config{libpth}.

Just to be sure that the problem is expressed clearly:
If, in GNUmakefile I change the (empty) EXTRALIBDIRS spec to:

EXTRALIBDIRS := C:\foo C:\bar

then in 5.24.0, $Config{libpth} will be set to
C:\wherever\lib C:\foo C:\bar

and that's fine. But in 5.25.2, $Config{libpth} will be set to
C:\wherever\lib "C:\foo C:\bar"

thus ensuring that any lib in C:\foo or C:\bar will not be located.

Cheers,
Rob

Finally worked out my mistake.

I had provided a *space-delimited* list to GNUmakefile's EXTRALIBDIRS -
which is what $Config{libpth} returns.
But EXTRALIBDIRS requires a *semicolon-delimited* list.

That sort of thing is quite counterintuitive, though the documentation is
clear enough.

Please close.

Rob
