why i cann’t connect to cean?

2008-11-23T19:48:55+01:00

i already had instaled Erlang and want to use CEAN on it,and download the zip archive of CEAN library. Then follow the instruction from the FAQ.

i add the follows to D:Program Fileserl5.6.5binerl.ini

set ARCHDIR=windows
set CEAN_SERVER=http://cean.process-one.net

i think i connect to internet directly,so i donot write"rem set HTTP_PROXY=your.proxy.host:port”

then i create VERSION file into my erlang ROOTDIR directory(D:Program Fileserl5.6.5) containing this: CEAN Erlang/OTP R12B-5 erts-5.6.5 windows devel

when i type cean:available().
it’s just tell me,
exception error: undefined function ibrowse:start/0
in function cean:geturl/3
in call from cean:getlist/0
in call from cean:available/0

ARM9 and CEAN

2008-05-26T13:43:22+01:00

Hello!
I use CEAN quite often on my x86 laptop. It works very well.
But I’ve tried to put it on an ARM9 linux arch but it doesn’t works:
(I’m logged as root on my device, /mnt/host is a NFS directory linked to my laptop where I can find the cean binary)

# pwd
/tmp
# /mnt/host/cean_installer.bin
installing CEAN…
./start.sh: line 85: /tmp/cean/erlang/erts-5.5.4/linux-arm/bin/erlexec: not found

Error installing erl_interface?

2008-11-09T10:43:59+01:00

Using the new cean release I’ve been able to install some packages (debugger, tools). But when I went to install erl_interface I got an error message. This is on Mac OS X 10.5.5. I’ve added the alias suggested in the FAQ and installed cean into /usr/local/cean Can anyone help?

CEAN-1.4 R12B-4 released

2008-10-29T00:13:57+01:00

CEAN-1.4 comes with Erlang R12B-4, and brings up many improvements in
the build process. The aim is to reach a production quality level of
autogenerated packages for all erlang contributions. The most valuable
improvements in CEAN-1.4 are:

* Work in cluster environment. It’s possible to sync CEAN
installation on several hosts using just one command.
* A better package dependency resolver. Generated
dependencies are reliable.
* Main commands available from bash. No need to join an
erlang shell to install packages.
* Lots of new packages.

CEAN also support updated packages for R11B-5. The cluster features are
backported to the R11B version as well.

This release should fix many old pending issues. Please report into that thread if you find some reported errors which are not solved.
Thanks.

Running yaws using cean

2008-04-25T06:20:53+01:00

Hi,

I am a newbie to erlang and to yaws. I would like to run yaws using cean. I have installed cean and yaws in cean—cean:display(installed). outputs “yaws” as the last entry. (All this is on a 64-bit AMD machine.)

Now how do I run the yaws that I installed using a custom config file that I have made? Is it possible to run the yaws by itself, or do I always have to start it from the interactive shell of cean?

yaws:start(). fails with the “failed to load setuid_drv” error that many people have reported.

Following the steps at http://www.erlang.org/pipermail/erlang-questions/2006-November/024153.html works as expected, without errors.

Is there a way to run yaws from a shell-script or some such, without having to type in all the configuration information in the interactive shell?

Thanks for your patience,
Philip

yaws not starting

2008-11-04T11:56:46+01:00

yaws packaging was not upgraded correctly
starting yaws will complain not finding setuid_drv driver.

short term fix:
cd erlang/lib/yaws-1.77/priv && ln -s linux-x86/lib
(change linux-x86 to you effective archdir of course)

long term fix:
i’ll upgrade the package this week so yaws:start() will work without change
i’ll not upgrade yaws version by now. so to apply change when new package will be ready:
cean:uninstall(yaws).
cean:install(yaws).

12.b.1

2008-02-29T22:02:05+01:00

Hi,

Is 12.b.1 supported? If not, is there a planned time-frame for this?

Just checking.

Thanks.

error: _ not found in download -R128-3

2008-09-10T20:33:20+01:00

I’m having the “not found in download” problem. I downloaded
the cean archive and added it to my working erlang installation.
I’ve edited erl, and added VERSION. I must still be missing something.

Note that cean:available(). does not work either - it returns a fragment
of a web page, not a list of available packages.

erlang was built with—prefix=/opt/erlang

/opt/erlang/bin/erl:

ROOTDIR=/opt/erlang/lib/erlang
BINDIR=$ROOTDIR/erts-5.6.3/bin
EMU=beam
PROGNAME=`echo $0 | sed ‘s/.*///‘`
export EMU
export ROOTDIR
export BINDIR
export PROGNAME
export ARCHDIR=linux-x86
export CEAN_SERVER=“http://cean.process-one.net”
exec $BINDIR/erlexec ${1+“$@“}

/opt/erlang/lib/erlang/VERSION

CEAN Erlang/OTP R128-3 erts-5.6.3 linux-x86 devel

Note that cean:version(). returns the string above, not “CEAN Erlang/OTP”,
so I assume I got the version bit correct.

Thanks for any help!

PS, the URI cean:available(). is GETting is /R128/devel/linux-x86. I note
that this results in a 200 OK and a page that states “page not found”. So
I tried this with /R118/devel/linux-x86 as shown in the example, and the
result is the same.

XCode integration

2008-09-01T11:27:40+01:00

Hi all,

can anyone give me some hints how to adjust XCode 3.0 for Erlang (which means setting up a new file type *.erl and define syntax highlighting etc. )?
I work already with XCode, but with more support it would be even nicer, and the Apple docs doesn’t help me a lot how to manage this.

Thanks !

Hans

Newbie probs or bug?

2008-08-07T22:28:14+01:00

I just downloaded and unzip installed cean (windows) into 12B-3

15> cean:version().
“CEAN Erlang/OTP”

Is this right?

also:

18> cean:install(ex11).
error: ex11 not found in download
error

19> cean:install(x11).
error: x11 not found in download
error

Rgds,

Matthew.
