Running on Linux kernels compiled with COMPAT_BRK disabled
by Stelian Ionescu 01 Feb '10

01 Feb '10

When run on a kernel compiled without COMPAT_BRK CMUCL segfaults, so I copied the kludge used by SBCL - check the current personality, and if necessary, enable ADDR_NO_RANDOMIZE and re-exec itself. Patch attached. -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur. http://common-lisp.net/project/iolib

Would ext:exit be a good addition?
by Alex Goncharov 30 Jan '10

30 Jan '10

Does anybody see a downside to introducing a simple way to exit REPL with a status, via something like `(exit 1)'? CMUCL has (defun quit (&optional recklessly-p) "Terminates the current Lisp. Things are cleaned up unless Recklessly-P is non-Nil." but that always exits with status 0, which is often not what is wanted. And (unix:unix-exit 1) is too long to type. `exit STATUS' is so common everywhere that it should be natural to use it in CMUCL, too. -- Alex -- alex-goncharov(a)comcast.net --

Bad 2010-01 non-unicode binaries for linux and darwin
by Raymond Toy 22 Jan '10

22 Jan '10

I just noticed that the 2010-01 snapshots for linux and darwin were built incorrectly. (I accidentally did a unicode build for them.) I've uploaded new versions and removed the old versions. The new versions have a different name to indicate these are different from the old versions. Sorry about that. Ray

Motifd and Motif library dependencies
by Raymond Toy 14 Jan '10

14 Jan '10

I upgraded from openSuSE 10.3 to openSuSE 11.2 a few days ago, and now I can no longer build motifd. For whatever reason, I now need to specify -ljpeg, -lpng, -lXmu, and -lXft to get these dependent libraries linked in. This wasn't required before for 10.3, but it is now. But from what I can tell, these dependencies were already in the 2010-01 binaries I built using openSuSE 10.3. Now I have to be explicit about this. For the maintainers of the various Linux distributions of cmucl, can I just add these libraries explicitly? Will that cause a problem? Ray

clx authorization and localhost
by Raymond Toy 11 Jan '10

11 Jan '10

I upgraded my openSuSE 10.3 system to 11.2 this past week, and now clx no longer works. I suppose it could be my setup but it seems clx should work a little better than this. What is happening is (open-clx-display) tries to get the best authorization. The host name, as returned by xlib::get-host-name is "lorien2". Get-best-authorization looks at my xauth file which just contains the entry for localhost/unix:0 MIT-MAGIC-COOKIE. This fails because of the clause: (when (and (eql family protocol) (equal host-address address) (= number display) (let ((pos1 (position name *known-authorizations* :test #'string=))) (and pos1 (or (null best-pos) (< pos1 best-pos))))) (setf best-name name best-pos (position name *known-authorizations* :test #'string=) best-data data)))) Here, host-address is "lorien2" and address is "localhost", and they're not EQUAL. Shouldn't there be something else here? Say if the protocal is :local, then check if address is "localhost"? (The xauth entry was not created by me. I think the X server did that automatically.) Ray

End of support for Solaris 8
by Raymond Toy 07 Jan '10

07 Jan '10

Solaris 8 is some ten years old, and it's finally time to stop building cmucl on solaris 8. All future builds will be done using Solaris 10 (which itself is about 5 years old). Is there anyone still using CMUCL on solaris 8? If so, can you upgrade? If not, I might reconsider this, but it will be a bit of work maintaining this. I want to retire my Solaris 8 box. Ray

Jan 2010 snapshot
by Raymond Toy 04 Jan '10

04 Jan '10

The first snapshot of the new year has been tagged. Binaries forthcoming. This snapshot includes experimental support for static vectors. They appear to work, but probably needs way more testing than I've done with them. Other random fixes have also been applied; see the release notes for details. Happy New Year, everyone! Ray
