638. ECCE on Centos 7

I use the minimal centos 7 iso from http://isoredirect.centos.org/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-1611.iso

It was pretty straightforward otherwise:

yum install vim csh gcc gcc-c++ gcc-gfortran java-1.7.0-openjdk-devel python-devel ant gtk2-devel libjpeg-turbo-devel libtool ImageMagick libXt-devel xterm mesa-libGLU-devel kernel-devel perl-Digest-Perl-MD5 perl-Digest-MD5 bzip2 perl-Env
mkdir ~/tmp
cd ~/tmp
Download ecce from http://ecce.pnl.gov/using/download.shtml into ~/tmp 
tar xvf ecce-v7.0-src.tar.bz2
cd ecce-v7.0/
export ECCE_HOME=`pwd`
cd build/
./build_ecce|tee xerxes.log
./build_ecce|tee mesa.log
./build_ecce|tee wxwidgets.log
./build_ecce|tee wxpython.log
./build_ecce|tee httpd.log
./build_ecce|tee ecce.log

If you want a desktop:
sudo yum -y groups install "GNOME Desktop" 
ECCE asks about netstat as well.

637. ECCE on Ubuntu 16.04.2

I just tried to build ECCE on Ubuntu LTS 16.04.2 according to http://verahill.blogspot.com/2015/06/611-building-ecce-on-debian-jessie.html and it worked without a hitch. The only things that needed changing were

* from openjdk-7-jdk in debian to openjdk-8-jdk in ubuntu
* src/inv/flclient/flfreetype.c: <ftoutln.h> needed changing to <freetype/ftoutln.h>

636. Bulk convert mp4 file to mp3 (avconv/xargs)

I have mp4 files that have weird characters etc. in them.

To handle them, I used the following to convert them using xargs and avconv:
find *.mp4 -print0|sed 's/mp4//g'|xargs -0 -I {} avconv -i {}mp4 {}mp3
