Can anyone explain this scons error with latest CVS?
On Windows, FLTK widgets will not build, I get this from scons

scons: ***ParentOfRoot instance has no attribute 'must_be_a_Dir'

which looks like a Python error message saying that that class
(from scons, node/FS.py) does not have that particular attribute defined)

After about two hours of scratching my head, I traced the problem
to the building of the FLTK module, so if I do

scons useFLTK=0

It builds.

Has anyone changed SConstruct, particularly in terms of build
options, directories etc that might have caused this?

It seems to be happening on Windows only, although I have to
check Linux more closely)

Only on Windows. It is related to widgets.cpp, because when
I remove it from the source list for that module (SConstruct, line 1237),
it builds.

That narrows it a bit more. Any suggestions?

It seems this line confuses scons:

InOut/widglobals.h, 61:

#include "Opcodes/vst4cs/src/vsthost.h"

Although not used in the compilation, scons seems to read
the file and gets confused. If I change it
to

#include "vsthost.h"

scons is OK with it.

It looks like scons is unable to follow the relative
path on Windows.

Suggestions for a fix?

Recently, I was having this error on Gnu/Linux too, when I rebuilt 
csound from cvs on a fresh Slackware 12 installation.

IIRC, I had to disable csound5gui and cseditor to make it build. And in 
fact my installation lacks csound5gui, the cseditor and everything that 
needs FLTK.

Well, now we know what the problem is, it will be fixed. It's a scons
thing, it gets confused with pathnames of header files. You should be
able to build with FLTK by removing the offending line in widglobals.h;
I think it is not doing anything anyway because the token it depends
on is not defined anywhere.

Forget what I've said; I've just realized that FLTK wasn't present on a 
fresh Slackware 12. I didn't notice it since scons didn't complain.

Building with csound5gui still fails, though (with fltk 1.1.7, gcc4.1.2):

`CsoundGUIConsole::updateDisplay(bool)':

And, by the way, FLTK opcodes don't work either.

That's because you need to have FLTK with --enable-threads,
for Fl::lock() to be present.

Right. Compilation went ok after rebuilding FLTK with threads support, I 
just forgot this step. Sorry for the noise.

Anyway, maybe I've discovered another problem:

If I build with buildUtilities=1 scons the linker complains that it 
can't find -lcsound. So I had to build with buildUtilities=0, run 
install.py, ldconfig and then add the option to scons and rebuild again.

yes, that does not sound right. Although here I did not have
that problem anywhere (Win, Linux, OSX). Are you using a
static libcsound or dynamic?

yes, the first thing I tried. But it doesn't work,
because when scons is parsing the header file it ignores
any such directives.

It's very strange because I just built Csound from CVS using 
dynamicCsoundLibrary=1
and the linker found -lcsound OK (there was a -L. in the command line) (FC6 
on a PPC).
Can you copy here the scons error message you had ?

If I do:
uninstall-csound

and then:
scons -c
scons install

build fails with:
gcc -o atsa -Wl,-Bdynamic util/atsa_main.o -L. -L. -L/usr/local/lib -L. 
-L. -lcsound -lsndfile -ldl -lpthread -lm
/usr/lib/gcc/i486-slackware-linux/4.1.2/../../../../i486-slackware-linux/bin/ld: 
cannot find -lcsound
collect2: ld returned 1 exit status
scons: *** [atsa] Error 1
scons: building terminated because of errors.

Since the error is with atsa, I set:

buildUtilities=0

It builds. Then I revert buildUtilities=1. Builds.

I am attaching my SConstruct file.

-c.
