[gentoo-dev] xemacs segfault

[gentoo-dev] xemacs segfault

[Dave Lee]

Hello,

Has anyone been able to figure out why xemacs segfaults on startup?  As
mentioned before, if you are emerge-ing something, than xemacs will
actually run w/o segfaulting.  This is strange behavior. TIA,  Dave

Which version?
Have you tried

  xemacs -debug-init
  xemacs -vanilla

Also try running in the terminal with

  xemacs -nw

Perhaps these would help you to pin-point the problem...

I did try -vanilla and -norc, but not the others.  I'll see what they do
for me.

I dont know, would it?  Can anybody see why xemacs would run just fine
when I am in the process of compiling something else, but when I am not
compiling anything it segfaults immediately.

I did try to run strace on xemacs, and although I dont have the results at
hand to cut and paste, the segfault was happening after a bunch of stat
calls that were looking for default.{elc,el,} but when I am compiling
something nothing happens here other than ENOENT.

I am pretty sure this is happening because xemacs is trying to load .elc files
generated by gnu emacs. Ths byte compiled lisp files (.elc) are not compatible
between Gnu emacs and xemacs. 

This probably happened because some package independent of both emacsen
installed *.elc files which were compiled by emacs, and then you installed
xemacs and are trying to run it.

How to check if this is the case:
 * unmerge emacs and xemacs
 * find / -name \*.elc -exec rm -f {} \; -print
 * remerge xemacs

And then try running it.

The second step removes all the *.elc files on your machine. This should not
cost you too much because loading .el files is only marginally slower than
loading *.elc files. You might want to rename the files instead of removing
them.

I dont even have standard emacs installed.  Also, the default* files dont
exist, and the stat calls are returning ENOENT.  IIRC, when I was able to
get xemacs to run while compiling something else, strace showed that after
those stat calls, the next thing that happened was a SIGIO whereas normal
xemacs execution doesnt ever get that SIGIO.  Dave

[gentoo-dev] There is a Bug about this xemacs segfault

[Sloan Poe]

[-- Attachment #1: Type: text/plain, Size: 337 bytes --]

this is a bugreport on this with a partial explanation as to why it
works when emerge is running:

http://bugs.gentoo.org/show_bug.cgi?id=1574


Though there seems to be a new ebuild out now 21.4.6-r1..

So now though I can't even get xemacs to compile.  It seems to hang
trying to find NAS which I have installed..

:(

so I compiled xemacs-21.4.6-r1 on my headless webserver, so no X.  When I
run xemacs here I have no problems at al.  Since this is in terminal mode
I assume its the equivalent of 'xemacs -nw'.  Here is the strace output

stat64("/usr/lib/xemacs-21.4.6/lisp/default.elc", 0xbfffe700) = -1 ENOENT (No such file or directory)
stat64("/usr/lib/xemacs-21.4.6/lisp/default.el", 0xbfffe700) = -1 ENOENT (No such file or directory)
stat64("/usr/lib/xemacs-21.4.6/lisp/default", 0xbfffe700) = -1 ENOENT (No such file or directory)
gettimeofday({1018271343, 614761}, NULL) = 0
gettimeofday({1018271343, 615396}, NULL) = 0

when xemacs was segfaulting on my home desktop machine, I never made it to
those gettimeofday calls. Still, I wonder what the hell could cause a
program to run fine only while emerge-ing.  I guess I will see what I can
figure out when I get home.  Dave

Re: [gentoo-dev] xemacs segfault

	Also there is a quirk in the xemacs configure file:
		If you have wine installed then it thinks that it is compiling for
windows, thus fails. This happens as it detects /usr/lib/libgdi32.so,
thus thinking it is windows.
