Hi all,
When I type 'emacs' at the bash prompt, emacs does not start and the
prompt re-appears very quickly as if nothing happened. 'emacs -Q' and
'emacs --version' do the same, nothing is printed.
My alternatives are set such that emacs points to emacs-w32. I also
have
emacs-nox and that works fine.
If I run 'strace emacs-w32' I get an error dialog:
"The procedure entry point WebPDecode could not be located in the
dynamic link library C:\cygwin\bin\cygMagickCore-6.Q16-2.dll."
Is this a known problem? If not I can attach cygcheck.out and the
output
from strace if that will help.
It's not a known problem.
It is now. I can reproduce the problem (only on 32-bit Cygwin). I'll
look into it.
The problem turns out to be related to the recent update of libgd3.
Reverting to the previous version fixes it.
Notice that cygMagickCore-6.Q16-2.dll, which occurs in the error dialog
above, depends on cyggd-3.dll:
$ cygcheck /usr/bin/cygMagickCore-6.Q16-2.dll | grep cyggd-3
C:\cygwin\bin\cyggd-3.dll
Marco, is it possible that the libgd3 update requires a rebuild of
ImageMagick?
Here's some further info:
objdump -p /usr/bin/cygMagickCore-6.Q16-2.dll
[...]
DLL Name: cyggd-3.dll
vma: Hint/Ord Member-Name Bound-To
48ee2c 8 WebPDecode
[...]
I assume this means that ImageMagick expects to find WebPDecode in
cyggd-3.dll. And it was indeed there in the previous version of libgd3:
$ objdump -p /usr/bin/cyggd-3.dll | grep WebPDecode
[ 8] WebPDecode
With the current libgd3, however, we get
$ objdump -p /usr/bin/cyggd-3.dll
[...]
DLL Name: cygwebp-5.dll
vma: Hint/Ord Member-Name Bound-To
5c0b4 272 WebPDecodeARGB
[...]
and there is no other occurrence of the string WebPDecode in the output.
