Erlang Install

[rajames429]

I am using Ubunut Precise (12.04 LTS) in VMWare (for months)

I had Erlang R14B04 installed.

I used the commands (below) to install R15B

everything went fine, but when I run erl at the command prompt, I get the R14B04 shell

I cannot locate the activate command (listed on another post)

How do I set erl to the new R15 version ?




The commands I used were:

apt-get -y install build-essential m4 libncurses5-dev libssh-dev unixodbc-dev libgmp3-dev libwxgtk2.8-dev libglu1-mesa-dev fop xsltproc default-jdk

mkdir -p /src/erlang

cd /src/erlang

wget http://www.erlang.org/download/otp_src_R15B.tar.gz

tar -xvzf otp_src_R15B.tar.gz

chmod -R 777 otp_src_R15B

cd otp_src_R15B

./configure

make

make install

NOTE: I used sudo where appropriate and I got no install errors!!

A simple solution would be to add the erlang path to the PATH variable in ~/.bashrc file. Something like this:
1. edit ~/.bashrc with a text editor (vim or other)

vim ~/.bashrc

2. add these lines (change path to your real erlang path)

ERLANG_HOME=/path/to/erlang15b
export PATH=$PATH:$ERLANG_HOME/bin

3. save and quit
4. load ~/.bashrc

source ~/.bashrc

5. try the erl command

erl

Another solution would be to install Erlang 15B via a PPA repository, like this one: https://launchpad.net/~scattino/+archive/ppa

Thank you. I located erlang (R15B) in /usr/local/lib/erlang.

I added the information to my .basrc as you suggested and it worked (will wonders ever cease ?!?!)
