Hi all.
After some time, compiling grass from cvs leaves me with non-executable
files in the bwidget directory. The problem is easily fixed (chmod +x),
but annoying nevertheless. Is this only my problem, or others are having
it? Does anybody have an explanation/solution for this?
All the best.

I didn't know they were supposed to be executable. On both my Grass
6.1 CVS 2006-06-19 and 6.02 CVS 2006_01_28 they are not. ?

If they're not executable, I get:

Error in startup script: can't find package BWidget 1.2.1
    while executing
"package require -exact BWidget 1.2.1"
    (file "/usr/lib/grass-6.1.cvs/etc/gm/gm.tcl" line 23)

BTW, with latest cvs I get:

GRASS 6.1.cvs (Toscana):~ > Error in startup script: can't read

and the GIS monitor does not start.
Am I the only unlucky one?
All the best.

OK, now it works - thanks!

The only (unrelated?) error I could spot in ./configure is:
checking whether to use GLw... yes
checking for location of GLw includes...
checking for GL/GLwMDrawA.h... no
checking for X11/GLw/GLwMDrawA.h... no
configure: error: *** Unable to locate GLwM includes.

For the rest, compilation seems to run smoothly, and this is the first
time I see this error.
Any hints?

All the best.

Just to make things clear, do you mean the tcl files
in /usr/local/grass-6.1.cvs/bwidget ?

I really never have had them executable, and all was fine. Strange.

I don't have this error at ./configure, unless I specify
--with-glw=yes, not having the GLw installed. Please note GLw is not
enabled by default. If you you haven't requested it, the error you
are getting is strange.

I also wonder what we need GLw for in Grass anyway? It's not even
mentioned on http://grass.itc.it/grass60/source/REQUIREMENTS.html nor
in README and INSTALL files. I've never used it.

My BWidget Tcl files don't have execute permission, and I don't have a
problem.

Or do the directories lack execute permission? That will certainly
cause problems.

Are you running with a bogus umask value (type "umask" in the shell to
find out)?

It's only used by r3.showdspf, which is no longer compiled even if you
do use --with-glw; AFAIK, it has been superseded by the inclusion of
3D raster functionality into NVIZ.

Note that GLw requires Motif, so the test will fail if you don't have
Motif (either OpenMotif or Lesstif) installed.

I know, but I'm on etch.
Anyway, Glynn explained glw is not necessary (it is compiled in the
debian package, though, and it has just been the object of a fix in the
packaging).
Thanks.

That isn't sufficient; that header will try to include <Xm/Xm.h>,
which will fail if the Motif headers aren't installed.

Lacking the Motif headers is far more likely than lacking the GLw
headers; on some systems (e.g. Gentoo), the GLw headers are part of
the base X.org-X11 installation.
