[erlang-questions] How to compiler Erlang for the TILEPro64?

[Björn-Egil Dahlberg]

Hi Stefan,

To compile Erlang for Tilera you can do the following,

1) Setup the Tilera Environment.
For example for me it is:

export TILERA_ROOT=/ldisk/tilera/TileraMDE-2.0.1.78377/tilepro
export PATH=$TILERA_ROOT/bin:$PATH

This is the cross compile environment supplied to you by Tilera Corp.

2) Setup The Erlang Build Environment:

tar -zxvf otp_src_R13B03.tar.gz
cd otp_src_R13B03
export ERL_TOP=`pwd`
eval `./otp_build env_cross 
$ERL_TOP/xcomp/erl-xcomp-TileraMDE2.0-tilepro.conf`

Crypto (and its dependencies) will not work so you need to SKIP those.

3) Build Erlang/OTP
touch lib/crypto/SKIP
touch lib/ssl/SKIP
touch lib/ssh/SKIP
./otp_build configure
./otp_build boot -a
./otp_build release -a <release dir>

4) Start Erlang,

cd <release dir>
./Install `pwd`
tile-monitor --pci --here -- bin/erl

Of course you would probably want to upload everything to the card, just 
like other applications you need to upload.

Contact Tilera Corp. for optimal settings and hardware configuration.

This should work on R13B03. However, from R13B04 this way will change 
and it will be better support cross compilation.

Regards,
Björn-Egil
Erlang/OTP
