Re: X protocol error

[Colin Baxter <m43cap@yandex.com>]

Dear Po,

Thanks for your reply. I have narrowed the problem to the configure option
"./configure --with-x-toolkit=lucid <RET>". If I run only "./configure
<RET>", effectively using the gtk3 default setting then emacs builds
successfully.

In an xterm, in my directory ~/git/emacs/src, if I launch gdb and then
enter your command. I get the following:

--8<---------------cut here---------------start------------->8---
gdb$ run -q -xrm "Emacs.synchronous: true"
Starting program:  -q -xrm "Emacs.synchronous: true"
No executable file specified.
Use the "file" or "exec-file" command.
--8<---------------cut here---------------end--------------->8---

I am obviously doing something stupid. I have not used gbd before so you
will have to talk me through the method in some detail. For instance,
must have compiled (made?) emacs using some debugger option? Sorry to
be dim.

Best wishes,
