It's been a few days since Erlang/OTP 17.0 has been released. Installing 64 Bit Erlang (with Observer support) on Mac OS X has always been a bit tricky, but with 17.0 it has gotten significantly easier.
First you need to install/get some prerequisites:
After you've gotten these three, we start by installing wxWidgets. It's required in order to use the Observer GUI.
{{< highlight bash >}} brew install wxmac {{< / highlight >}}
Compiling wxWidgets might take some time. After it's done, you should create a ~/.kerlrc file. It's basically a configuration file for kerl, which will be used for every Erlang version you compile. You can find the list of available options in the kerl readme. Mine looks like this:
{{< highlight bash "linenos=table" >}} CPPFLAGS="-march=native -mtune=native -O3 -g" KERL_CONFIGURE_OPTIONS="--disable-debug --without-javac --enable-shared-zlib --enable-dynamic-ssl-lib --enable-smp-support --enable-threads --enable-hipe --enable-kernel-poll --enable-darwin-64bit --with-wx" KERL_DEFAULT_INSTALL_DIR="$KERL_BASE_DIR/installs" {{< / highlight >}}
We can now move on to actually installing Erlang/OTP 17.0.
{{< highlight bash >}} kerl update releases kerl build 17.0 17.0 kerl install 17.0 17.0 {{< / highlight >}}
After the installation is finished, kerl will output instructions on how to enable a specific Erlang version globally. In general, you will put something like the following in your ~/.zshrc or ~/.bash_profile:
{{< highlight bash >}} source $HOME/.kerl/installs/17.0/activate {{< / highlight >}}
The following alias makes it easier to start the Observer from a terminal. The only command you have to remember is erlobserver.
{{< highlight bash >}} alias erlobserver='erl -sname observer -run observer -detached' {{< / highlight >}}
