GDB built with Guile won't start when boot-9 is unavailable.

GDB built with Guile won't start when boot-9 is unavailable.

[Eli Zaretskii]

Someone tried to run GDB 7.8 that I built with Guile support without
installing Guile first.  (libguile was statically linked into GDB, so
no shared library was needed.)  They reported that GDB bailed out with
the following error message:

  Throw without catch before boot:
  Throw to key misc-error with args ("primitive-load-path" "Unable to find 
  file ~S in load path" ("ice-9/boot-9") #f)Aborting.

AFAIR, a snapshot I built about 2 months ago didn't bail out, it just
printed a warning that Guile support will be partial.

Is it possible to avoid the fatal error in this case?

Sorry, ignore this: it's because Guile was installed in a directory
other than the one it was configured for, and GUILE_LOAD_PATH was not
set.

Ah.

There's still a problem here, as evidenced by requests to have gdb
more tolerant, e.g., of missing Python.
Same reasoning applies to Guile.

Indeed.
