libungif and emacs-cvs

[Angelo Graziosi]

Building emacs-cvs, 'configure' gives:

----------------------------------------------------
checking gif_lib.h usability... yes
checking gif_lib.h presence... yes
checking for gif_lib.h... yes
checking for EGifPutExtensionLast in -lungif... no
---------------------------------------------------

so that it buids without ungif support:

--------------------------------------------------------------------
...
Configured for `i686-pc-cygwin'.

  Where should the build process find the source code?    /tmp/emacs
  What operating system and machine description files should Emacs use?
        `s/cygwin.h' and `m/intel386.h'
  What compiler should emacs be built with?               gcc -g -O2 
  Should Emacs use the GNU version of malloc?             yes
  Should Emacs use a relocating allocator for buffers?    yes
  Should Emacs use mmap(2) for buffer allocation?         no
  What window system should Emacs use?                    x11
  What toolkit should Emacs use?                          LUCID
  Where do we find X Windows header
files?                /usr/X11R6/include
  Where do we find X Windows libraries?                   /usr/X11R6/lib
  Does Emacs use -lXaw3d?                                 yes
  Does Emacs use -lXpm?                                   yes
  Does Emacs use -ljpeg?                                  yes
  Does Emacs use -ltiff?                                  yes
  Does Emacs use -lungif?                                 no   < === 
  Does Emacs use -lpng?                                   yes
  Does Emacs use X toolkit scroll bars?                   yes
...
----------------------------------------------------------------

I do not remember this behaviour previously (but it could be), so I flag
this in the case it is a problem with libungif.

Emacs-cvs requestes libungif 4.1.0b1 or higher and I have installed
libungif, libungif4 packages 4.1.4

I have all Cygwin installed and updated.



Cheers, Angelo.

It would probably be enlightening to look at config.log to see *why*
configure thinks EGifPutExtensionLast is not in -lungif...

Or something else completely unrelated that caused the test program to
fail, thus making configure think that it didn't have a valid -lungif.

I didn't catch the beginning of this thread... but
I frequently build cvs emacs (once a month) with cygwin and based on
cygwin's x-windows.

I do not have any probllem with ungif.

  * I do specify the following  configure option
       ---with-gif

* Last year's (of so) version of ungif had some problems, be sure to
get the newest with setup.exe

* The newest cygwin gtk windowning is broken somethwere, so I had to use
   ---with-Xaw3d

(gtk people fix that!)

I am frequently building emacs from cvs and have not noticed this
problem, but haven't looked

Perhaps try uninstalling and reinstalling the ungif library.

In any case...

I think it was a problem of emacs cvs of that time.

Now I have tried newly with emacs-cvs date 20060912 09:00 and 

-----------------------------
  Does Emacs use -lXaw3d?                                 yes
  Does Emacs use -lXpm?                                   yes
  Does Emacs use -ljpeg?                                  yes
  Does Emacs use -ltiff?                                  yes
  Does Emacs use -lungif?                                 yes  < ===
  Does Emacs use -lpng?                                   yes
  Does Emacs use X toolkit scroll bars?                   yes
