configure fails on checking ino_t

configure fails on checking ino_t

[Lloyd Wood via cygwin]

download geomview 1.9.5 from http://www.geomview.org
this used to build on cygwin 32-bit. Did so for a number of years. Now, it doesn't,
because something changed.

$ tar xvfz geomview-1.9.5.tar.gz
$ cd geomview-1.9.5
./configure
[..]
checking for dev_t... yes 
checking for ino_t... yes 
checking for time_t... yes 
checking size of dev_t... 4 
checking size of ino_t... configure: error: in `/home/ellowoo/savi/geomview-1.9.5': 
configure: error: cannot compute sizeof (ino_t) 
See `config.log' for more details 


$ tail config.log
[..]
#define TIME_WITH_SYS_TIME 1 
#define HAVE_M_PI 1 
#define HAVE_DEV_T 1 
#define HAVE_INO_T 1 
#define HAVE_TIME_T 1 
#define SIZEOF_DEV_T 4 

configure: exit 77 

Okay, so what changed in Cygwin?
(No, Mario, this is not an antivirus thing...)

thanks

I hope nothing, because it works for me:

checking for dev_t... yes
checking for ino_t... yes
checking for time_t... yes
checking size of dev_t... 4
checking size of ino_t... 8
checking size of time_t... 8
checking size of long... 8
checking size of int... 4


You should at least post the relevant part from config.log (the part
beginning with

configure:17957: checking for ino_t

).

hi Csaba

that part of config.log is not interesting:

[..]
configure:17948: result: yes
configure:17957: checking for ino_t
configure:17957: gcc -c -g -O2  conftest.c >&5
configure:17957: $? = 0

I'm very puzzled. But don't run Cygwin setup in
case it breaks your setup, is my thought...

Aha! just slightly later in config.log:

configure:17957: gcc -c -g -O2  conftest.c >&5 
configure:17957: $? = 0

if (sizeof ((ino_t))) 
^ 
configure:17957: $? = 1 
configure: failed program was:

| #define PACKAGE_NAME "geomview" 


this is with:


It was created by geomview configure 1.9.5, which was 
generated by GNU Autoconf 2.69.  Invocation command line was 

$ ./configure 

thanks for the hint, but still puzzled as to why this starts
failing now.

This _particular_ failure is expected (you aren't showing enough of the
config.log output).  Remember, to determine if something is a type vs.
an expression, autoconf performs TWO compilation tests, and relies on
the fact that sizeof(expr) and sizeof((expr)) both compile, but
sizeof(type) compiles while sizeof((type)) must fail.  The back-to-back
compilation is necessary to ensure that something being probed for is a
type name rather than an arbitray expression.

So just because _some_ tests fail (as expected) does not mean that this
particular failure is where configure is messing up.

Results may depend on whether the package includes its own collection of
macros, relies on the distro released macros, or includes some of its
own to override the distro macros.

The contents of config.log appear to be not just streams of messages as
you might expect, but collections of different outputs generated during
processing, sometimes requiring a bit of jumping around to fully
comprehend.

So please attach the complete config.log as a text attachment, or post
it on some storage web site if too large, so others can review it and
assist you.

And as usual, please attach cygcheck -svr output as a text attachment,
so support folks can see what tools releases you are running.

As the current release is the only release which is supported and can be
fixed, you may need to keep a number of frozen releases around to avoid
any build issues, or rely on crouchingtigerhiddenfruitbat.org packages.
That may cause issues when others try to run your package on more recent
releases.

Yes, I saw this in my successful config.log (and was a bit puzzled).

Lloyd, you need to look further down in config.log, because "checking
for sizeof(ino_t)" - the one that failed for you - is after "checking
for ino_t".

I've just build geomview-1.9.5 on both 32-bit and 64-bit Cygwin, using 
the attached cygport file and patches.

If it works well, I'll propose it for inclusion in the Cygwin 
distribution.  I have no experience with geomview, so I can't really 
test it adequately.  Would you be willing to try out my build and tell 
me if it seems OK?

If so, you can get it from my personal Cygwin repository:

There are instructions at that site.  Note: I have other packages there 
that you probably don't want to install, so be careful to just choose 
geomview (and let setup install its dependencies).

Re: configure fails on checking ino_t

[Lloyd Wood via cygwin]

Hi Ken,

thanks for this - both 32-bit and 64-bit Geomview from
your repository work as expected. I was able to run
SaVi (http://savi.sf.net/) under both, with OpenGL and
piping between Geomview and SaVi working so that
SaVi could control Geomview.

(64-bit working with SaVi was a pleasant surprise -
I had not been able to get piping between Geomview
and remote control apps working previously in 64-bit,
when compiling Geomview myself. And 64-bit OpenGL
is good to finally see working, too.)

However, Geomview's supplied modules aren't listed in
the right panel of its main window,
suggesting it hasn't been configured and built with xforms
and with Tcl/Tk, which its modules need. I have
some notes with hints on this at:
http://personal.ee.surrey.ac.uk/Personal/L.Wood/software/SaVi/running-under-Windows/

Add in the Geomview modules in a -2, and I think both 32- and
64-bit Geomview will be more than good to include in Cygwin
distributions, which would be worthwhile since building
Geomview can be very tricky.(*)

On a related note, as you're associated with Cornell Math
you know of DsTool. Patrick Worfolk worked on the v3 Tk version of
that before he did SaVi, which I maintain, and it
can also work with Geomview.

DsTool can be made to work on 32-bit Cygwin with Tcl/Tk 8.5
(not 64-bit or 8.6 - seems to be reaching end of life as
is) and could, with a bit of updating, be
made current as another optional Geomview
module that can also run standalone without
Geomview, just like SaVi.
I have some notes on DsTool at
http://personal.ee.surrey.ac.uk/Personal/L.Wood/software/DsTool/
and there's some recent discussion of DsTool on the
geomview-users mailing list.

(*) Okay, I'm now aware of the BLODA issue, which likely
explains why configure tests fail in my building Geomview,
suggests that anything needing autotools to build may be best
off as an installable package, and also helps explain
why Cygwin is slow, particularly in disk accesses,
on an i5 machine, and why my typing in cygwin
occasionally does things like:

$ whhhicccchhhhhhhhhhhh   geeomview 
bash: whhhicccchhhhhhhhhhhh: command not found

Hi Lloyd,

Thanks for testing.

It looks like this has changed.  There's no longer a --with-xforms 
configure option, and the modules requiring xforms or Tcl/Tk are now 
packaged separately.  (See the top-level README.)  I'll think about how 
to best package these modules.

Thanks, I'll take a look.

Re: configure fails on checking ino_t

[Lloyd Wood via cygwin]

Ken,


you're right; I'm so used to seeing those modules listed that
I forgot that how they get there recently changed.
(Well, recently in Geomview terms...)

Separate modules from base Geomview now, xforms is no longer a dependency, which is good.
So, the base Geomview is good to go into Cygwin without them, I think.

thanks

L.
