ASDF now loads fine and SLIME also builds fine and works, thanks for
the quick fixes!
A strange thing was that even after these fixes, at first ASDF loaded
fine, but somehow the SLIME build still failed the same way as before.
It succeeded several times afterwards.
Then I noticed that the crow-httpd build also failed with mmap errors
(the httpd I had written for ECL). So I noticed after a few tests
that often loading more than one fasl, or even a single one twice in a
row failed:
$ cat hello.lisp
(defun hello ()
(format t "Hello, world!~%"))
$ /usr/local/ecl/bin/ecl
[...]
> (compile-file "hello")

;;; OPTIMIZE levels: Safety=2, Space=0, Speed=3, Debug=0
;;;
;;; Compiling (DEFUN HELLO ...).
;;; End of Pass 1.
;;; Emitting code for HELLO.
;;; Finished compiling hello.

I then assumed that there must be something odd going on with the
loader, so used ktrace(1) on the process to get a clue:
First load:
8032 1 ecl CALL open(0x26014a8,0,0x2f2f2f2f2f2f2f2f)
8032 1 ecl NAMI "/home/mmondor/work/mmsoftware/cl/server/hello.fas"
8032 1 ecl RET open 5
8032 1 ecl CALL __fstat50(5,0x7f7fffffc7b0)
8032 1 ecl RET __fstat50 0
8032 1 ecl CALL mmap(0,0x1000,1,1,5,0,0)
8032 1 ecl RET mmap 140187598168064/0x7f7ff7fda000
8032 1 ecl CALL munmap(0x7f7ff7fda000,0x1000)
8032 1 ecl RET munmap 0
8032 1 ecl CALL mmap(0,0x201000,5,0x15000002,5,0,0)
8032 1 ecl RET mmap 140187535409152/0x7f7ff4400000
8032 1 ecl CALL mmap(0x7f7ff4600000,0x1000,3,0x12,5,0,0)
8032 1 ecl RET mmap 140187537506304/0x7f7ff4600000
8032 1 ecl CALL mmap(0x7f7ff4601000,0,3,0x1012,0xffffffff,0,0)
8032 1 ecl RET mmap 140187537510400/0x7f7ff4601000
8032 1 ecl CALL mprotect(0x7f7ff4401000,0x1ff000,0)
8032 1 ecl RET mprotect 0
8032 1 ecl CALL close(5)
8032 1 ecl RET close 0
Second load:
8032 1 ecl CALL open(0x2934ce8,0,0x2f2f2f2f2f2f2f2f)
8032 1 ecl NAMI "/tmp/ecl08032a"
8032 1 ecl RET open 5
8032 1 ecl CALL __fstat50(5,0x7f7fffffc7b0)
8032 1 ecl RET __fstat50 0
8032 1 ecl CALL mmap(0,0x1000,1,1,5,0,0)
8032 1 ecl RET mmap 140187598168064/0x7f7ff7fda000
8032 1 ecl CALL munmap(0x7f7ff7fda000,0x1000)
8032 1 ecl RET munmap 0
8032 1 ecl CALL mmap(0,0x201000,5,0x15000002,5,0,0)
8032 1 ecl RET mmap -1 errno 13 Permission denied
8032 1 ecl CALL close(5)
8032 1 ecl RET close 0
Immediately I remembered that /tmp/ is a memory filesystem mounted with
a no-exec option, which was probably the issue, as the new ECL
uses /tmp/ where it previously used the current directory. So I looked
for an option to be able to configure this. As I didn't immediately
find it using APROPOS and explicitely loading ASDF and setting
ASDF/STREAM:*TEMPORARY-DIRECTORY* didn't help, I looked at the code:
In c/ffi/libraries.d:
cl_object copy = make_constant_base_string("TMP:ECL");
In lsp/config.lsp.in:
(let (x)
(cond ((and (setf x (ext:getenv "TMPDIR"))
(probe-file x)))
((and (setf x (ext:getenv "TEMP"))
(probe-file x)))
((and (setf x (ext:getenv "TMP"))
(probe-file x)))
(t (setf x #+unix "/tmp" #-unix "./")))
(si::pathname-translations "TMP"
`(("**;*.*" ,(format nil "~A/**/*.*" x)))))
This uses the UNIX feature which now seems to be OS-UNIX (I've not
grepped yet for these but it's not impossible that there are other uses
of UNIX). But by setting the TMPDIR environment variable to another
directory without execution limitations, everything loads fine again.
I also confirm that my own software works fine under the current ECL
once the TMPDIR environment variable is set.
If that's not already possible, do you think that it would be a good
idea to also configure the temporary path via a variable, such that it
can be set in ~/.eclrc ?
Thanks again,
