Unable to install Tsung and Erlang in Red Hat Linux

2010-06-08T09:43:47+01:00

I am using Red Hat Linux. I have followed the below steps:
1. I have downloaded the erlang package un der /saurabh directory.
2. Then did un-tar of ‘otp_src_R13B04.tar.gz’. Now from ‘/saurabh/otp_src_R13B04’ ran command ‘./configure’. It did someting. Attached is the file ‘erlangInstall.txt’ (in Attachememt.zip) which lists the ./configure process. Below warning observed:
configure: WARNING: No odbc library found skipping odbc
configure: WARNING: “ODBC library - link check failed”
configure: WARNING:
wxWidgets must be installed on your system.

Please check that wx-config is in path, the directory
where wxWidgets libraries are installed (returned by
‘wx-config—libs’ or ‘wx-config—static—libs’ command)
is in LD_LIBRARY_PATH or equivalent variable and
wxWidgets version is 2.8.4 or above.
configure: WARNING: No ‘fop’ command found: the documentation can not be built
configure: WARNING: Could not find any usable java compiler, will skip: jinterface

3. Now did un-tar of ‘tsung-1.3.1.tar.gz’.
4. Then from ‘/saurabh/tsung-1.3.1’ folder ran ‘./congure’. It showed following output:
[root@AUT-LIN-IMASR1 tsung-1.3.1]# ./configure

Adobe Flex - Erlang connectivity?

2009-03-18T20:20:58+01:00

Does anyone know of any examples of how to get Adobe Flex to communicate with Erlang?

Flex on the client and Erlang on the back end would be a real best-of-breed system.

Thanks.

Incorrect content type upon download

2009-12-18T18:50:36+01:00

I just tried to download the CEAN installer for mac os x 86 (R12B developer) and the content type appears to be set as text/plain which causes the whole program to display in my browser windows. I am using google chrome, it seems like the browser isnt smart enough to handle .bin files, maybe the content type should be set to application/octet-stream or the content zipped in a zip file avoid that ?

It is possible to load a local application instead a remote one ?

2009-12-01T19:45:27+01:00

hello,

I want to use my erlang app with CEAN, so I need, somehow load it into CEAN, it is possible?

Thanks

How get connected to the CEAN server from a proxy on windows ?

2009-12-01T18:59:47+01:00

Hello,
I download the CEAN installer for windows, execute start.bat, and in the console

I wrote:

“cean:available().”

and I get:

“error: conn_failed
[]
” I dont have direct connection to internet, I use a http proxy, so there are some way I can configure CEAN to take this in consideration ???

Thanks

R13B and “failed to find dependencies: no_pub_file”

2009-11-26T23:08:45+01:00

I am unable to get cean to work on my system. I’ll describe the system later, but let me show the symptoms first.

(1) When I do cean:available() the resultant list shows lines of HTML.

Eshell V5.7.2  (abort with ^G)
1> cean:available().
["        <li class="last"><a >Contribute</a></li>",
 "        <li><a >Home</a></li>",
 "        <li><a >About</a></li>",
 "        <li><a >Documentation</a></li>",
 "        <li><a >Downloads</a></li>",
... etc 

Checking with tcpdump, I see that it is actually sending


GET /R13B/devel/linux-x86.vsnlst HTTP/1.1

and getting a 404 error page back.

(2) cean:search actually seems to work.

2> cean:search(ldap).
[{"erldir","erldir is an open source DNS and LDAP server"},
 {"eldap","This is the Erlang LDAP library"}] 

(3) cean:install fails with “failed to find dependencies: no_pub_file”.

3> cean:install(eldap).
eldap was not installed. failed to find dependencies: no_pub_file
error
4> 

A tcpdump shows it sending

GET /R13B/meta/eldap.pub HTTP/1.1
Host: cean.process-one.net 

and again getting a 404.

Now, if I point a browser at http://cean.process-one.net/R13B/ I get a 404, but if I point it at http://cean.process-one.net/R12B/ I get a directory listing. So I’m guessing the problem may be as simple as cean not supporting R13B yet - in which case, are there plans to do so? However if that is the problem, then at least the error handling of the cean client could be made a whole lot better.

Regards,

Brian.

Platform details: (X)ubuntu Karmic with its default erlang R13B01. Unfortunately, ubuntu doesn’t have erlang-cean or erlang-ibrowse packages. So I untarred cean-1.4 and ibrowse-1.4.1 into ~/erl_lib and set ERL_LIBS to /home/brian/erl_lib. I had to compile ibrowse using

cd src
mkdir ../ebin
make 

ibrowse has a separate c_src directory which I ignored, as there’s no makefile except a build script for darwin.

I also created a file /usr/lib/erlang/VERSION containing:


CEAN Erlang/OTP R13B-1 erts-5.7.2 linux-x86 devel

and added a couple of lines to /usr/bin/erl:

export ARCHDIR=linux-x86
export CEAN_SERVER="http://cean.process-one.net" 

I have a such an erro in running this command ./erl -name ejabberd@sles10uday1.persiste nt.co.in -mnesia dir “/opt/ejabberd-2.0.5/databse/” -mnesia ex

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.

Windows archive contains debug symbol tables

2009-02-23T14:37:54+01:00

Hi!

The Windows archives contain the debug symbol tables and debug binaries, making them twice as large as necessary. Could you please consider removing them? Possibly add a “Windows debug” architecture instead.

best regards,
Vlad

Group several architectures in one download

2009-02-23T14:47:28+01:00

Hi!

We are considering packaging erlIDE with a minimal Erlang system, the way Java applications may contain a private copy of the JRE. This would mean the three or four most used architectures on the workstations (Windows, Linux x86, Mac PPC & x86) and the libraries are common to them. Would it work to just unpack all archives in the same directory?

Actually, my intention was to ask if you could consider providing such an archive yourselves, but I suppose that unless this is requested by more users it would more work than it’s worth…

best regards,
Vlad
