I'm using psl reduce, and I can run it in the terminal but cannot load any packages. I found the unix-install.pdf in /psl which mentioned setting a $reduce variable but this doesn't work. Is there an env variable that needs to be set?

BTW, this is on Mac OS X.

Could please go

on verboseload;

Then try loading a package, and post your commands and the outputs/errors here.

Please also post the value of

lisp loaddirectories!*;

There is a bug in your .reducerc. In the Terminal:

mv /Users/marbre/.reducerc /Users/marbre/.reducerc_hide

and try again.

More precisely it appears that you have got some support for Texmacs in there, which does not work anymore.

Thomas

I see a problem right away: the build was staged in the directory '/opt/local/var/macports/build/_Users_marbre_ports_math_reduce-algebra/reduce-algebra/work/trunk..' but then moved to ''/opt/local/libexec/reduce-algebra/.."

Same applies for /psl/

Is there a variable that can be set, or a file that can patched to show the correct lisp load directory?

The load path is in the Lisp variable loaddirectories!*, you can set this in your ~/.reducerc like:

lisp(loaddirectories!* := '("" "/opt/local/libexec/reduce-algebra/work/trunk/pslbuild/x86_64-mac_10.7_lion-darwin11.2.0/red/"
"/opt/local/libexec/reduce-algebra/work/trunk/pslbuild/x86_64-mac_10.7_lion-darwin11.2.0/psl/"));

Check the paths!

Thomas

Thanks.

I was writing a portfile (tcl script) for the MacPorts package manager. MacPorts has a staged process in which builds everything in a temp directory and if it succeeds, then it moves (stages) the final build into a permanent location. The load directories that were reported are the temporary ones (which no longer exist).

sturm@lennier[~/Cloud/Dropbox/reduce-algebra/trunk/psl] grep loaddi *
bootstrap.sh:(setq loaddirectories!* '("" "$here/red/" "$here/psl/"))
build.sh:(setq loaddirectories!* '("" "$here/red/" "$here/psl/"))
build.sh:(setq loaddirectories!* (quote ("" "$here/red/" "$here/psl/")))
mkredpsl.dat.for.vista:(setq loaddirectories* '("" "$reduce\lisp\psl\win32\red\"
noncoremodule.sh:  loaddirectories!* := "red/" . "psl/" . loaddirectories!*;
reduce.img.dat.bat:(setq loaddirectories!* (list "" (bldmsg "%w\..\red/" (getenv "here"))
reduce.img.sh:(setq loaddirectories!* (quote ("" "$here/red/" "$here/psl/")))

If you want a smart solution for the future, you can probably hack into the variable $here …

In line 285 of trunk/psl/build.sh there is

(setq loaddirectories!* (quote ("" "$here/red/" "$here/psl/")))

I think this is the value of loaddirectories!* that finally gets dumped into the image in line 345:

(savesystem "REDUCE" "$fasl/reduce" (quote ((read-init-file "reduce"))))

… but afterwards the noncore modules are compiled using that image. So you you probably want to rebuild the image with the new loaddirectories!* at the very end.

I like the idea of having reduce in MacPorts. I will be happy to support you (but for today, I have to go to bed now).

Thomas

Great! If I need answers, I know where to ask : )

BTW, the reduce plugin does work in TeXmacs with psl version. According Andrey Grozin, csl reduce does not change its prompt after loading tmprint, and TeXmacs cannot recognize it as a prompt.

I think it would be best to create a second image after all the modules have been built, with the final value of loaddirectories!*. Otherwise loading a module your will always search the build directories first (if they exist).

Basically, you take from psl/build.sh all the lines from

echo ++++++ Now create the reduce image file ++++++

to

XXX

and modify the pathsnames to your liking.

The same needs to be done for Linux .rpm and .deb packages as well. I'll look at this later when I have a bit more time.

Maybe we could use the configure option "-prefix" to optionally trigger this?

Thomas

I've just checked in a new script psl/saveimage.sh .

  Rainer

Thanks, I'll take a look at it.

I'm getting a shell command failure on saveimage.sh, line 81:

"./bpsl -td $STORE <<XXX > $chere/log/reduce.blg"

I've looked everywhere but cannot locate /logreduce.blg

I found:

/opt/local/var/macports/build/_Users_marbre_ports_math_reduce-algebra/reduce-algebra/work/trunk/pslbuild/x86_64-mac_10.7_lion-darwin11.2.0/buildlogs/reduce.img.blg

Has the directory

/opt/local/var/macports/build/_Users_marbre_ports_math_reduce-algebra/reduce-algebra/work/trunk/pslbuild/x86_64-mac_10.7_lion-darwin11.2.0/log

been created?

Was is the error message?

Thomas

Thomas,

The saveimage.sh script isn't behaving. I've been communicating with Rainer on the mailing list.

I run the script after macports moves (activates) the build into the install directory, but get an error:

:info:activate /opt/local/libexec/reduce-algebra/psl/saveimage.sh: line 93: ./bpsl: No such file or directory

I've posted an updated Portfile to MacPorts for psl version of Reduce, using r1534 saveimage. sh. I'll let you know when the changes are committed. When I get the time, I'd like to incorporate csl version.

Thanks for all your help!
