[cmucl-help] no such program error invoking run-program?

[Jared C. Davis]

Hi,

I just downloaded CMUCL 21(a) from the Linux tarball.  In a fresh
directory if I create a little file, temp.sh, like this:

     $ pwd
     /home/users/jared/cmucl-run-bug

     $ cat temp.sh
     #!/bin/sh
     echo "Hello world"

     $ chmod +x temp.sh

Then I am successfully able to run-program this script when I
give it the full path:

     * (run-program "/home/users/jared/cmucl-run-bug/temp.sh" nil :output t)
     Hello world

     #<process 24944 :EXITED>

But weirdly run-program fails when I tell it to run ./temp.sh:

     * (run-program "./temp.sh" nil :output t)

    Error in function RUN-PROGRAM:  No such program: "./temp.sh"
       [Condition of type SIMPLE-ERROR]

    Restarts:
      0: [ABORT] Return to Top-Level.

    Debug  (type H for help)

    (RUN-PROGRAM "./temp.sh" ("./temp.sh") :ENV NIL ...)
    Source: Error finding source:
    Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no
longer exists:
      target:code/run-program.lisp.

    0] backtrace 10

    0: (RUN-PROGRAM "./temp.sh" ("./temp.sh") :ENV NIL ...)

    2: (LISP::%TOP-LEVEL)
    3: ((LABELS LISP::RESTART-LISP SAVE-LISP))

I tried to reproduce this on another computer, but it works fine
there.  I don't know if there might be something wrong with how
I'm invoking CMUCL, but I simply:

   - Downloaded the cmucl-21a-x86-linux.tar.bz from:
       https://common-lisp.net/project/cmucl/downloads/release/21a/

   - Extracted it to somewhere
       (/share/apps/fv/jenkins/support/cmucl/cmucl-21a)

   - Wrote the following script to invoke it:

       $ cat ~/bin/cmucl
       #!/bin/sh
       exec /share/apps/fv/jenkins/support/cmucl/cmucl-21a/bin/lisp "$@"

I'm a little curious about the "Error finding source" message
above and I don't know if that's to be expected.

Various debugging information in case it's useful:

    uname -a:
    Linux compute-1-3.local 2.6.32-431.el6.x86_64 #1 SMP Thu Nov 21
13:35:52 CST 2013 x86_64 x86_64 x86_64 GNU/Linux

    cmucl banner:
    CMU Common Lisp 21a (21A Unicode), running on compute-1-3.local
    With core: /share/apps/fv/jenkins/support/cmucl/cmucl-21a/lib/cmucl/lib/lisp-sse2.core

    See <http://www.cmucl.org/> for support information.
    Loaded subsystems:

    CLOS based on Gerd's PCL 2010/03/19 15:19:03

I tried building CMUCL from source and seem to run into the same
issue.  But then, I'm invoking it in a similar way, so hopefully
I'm just doing something obviously stupid.

Cheers,
Jared
