Installing CasperJS 1.1.4 on AWS (CentOS)

Installing CasperJS to work with PhantomJSs latest version 2.1.1

This is the current status of my test installation. My perviously hacked version of CaserpJS ( instructions are there: Helping CasperJS 1.1.0-beta3 play nice with PhantomJS 2.0.0 ), however it’s time to rev-up to the non-beta version of the code.

Step 1 — Clone CasperJS from Git

Hopefully you already have Git installed, and you are ready to clone:

git clone git://github.com/n1k0/casperjs.git
Cloning into ‘casperjs’…
remote: Counting objects: 14392, done.
remote: Compressing objects: 100% (7/7), done.
remote: Total 14392 (delta 0), reused 0 (delta 0), pack-reused 14385
Receiving objects: 100% (14392/14392), 8.50 MiB | 0 bytes/s, done.
Resolving deltas: 100% (8648/8648), done.
Checking connectivity… done.

Step 2 — Perform Installation

Using hints from the Instructions at CasperJS 1.1.0-DEV documentation, I first located my current casper image, moved it aside, then linked the new one into it’s location.

whereis casperjs
casperjs: /usr/bin/casperjs /usr/local/bin/casperjs /opt/n1k0-casperjs-e3a77d0/bin/casperjs /opt/casperjs/bin/casperjs /opt/casperjs/bin/casperjs.exe

mv /usr/bin/casperjs /usr/bin/casperjs.1.1.0-beta3

ln -sf `pwd`/bin/casperjs /usr/bin/casperjs

Step 3 — Verify Casper

Running casper, I checked to ensure it’s on the latest version:

casperjs
CasperJS version 1.1.0-beta5 at /opt/casperjs, using phantomjs version 2.1.1

This looks like it’s good to go.. now CASPER AWAY!!

Installing PhantomJS 2.1.1 on AWS (CentOS)

phantomjs-logoIt’s a gamble to do this, and according to the build script it’s going to take a long time to complete the compile / install of Phantom 2.1.1.

Note: If you are looking for instructions on building for Ubuntu, the steps are different. I’ve documented that process in this post: Installing PhantomJS 2.1.1 on Ubuntu.

Step 1 — install required dependencies

You may or may not have most of these on your AWS / CentOS system. I found that most of these were required to start the PhantomJS build.Here are the ones that I’ve confirmed I needed:

  • autoconf
  • pkgconfig.x86_64
  • python26-pyudev.noarch
  • python26-twisted.noarch
  • sip.x86_64
  • python27-pyudev.noarch
  • python27-twisted.noarch
  • gcc
  • flex
  • bison
  • xorg-x11-server-Xorg.x86_64
  • xorg-x11-server-devel.x86_64
  • xorg-x11-utils.x86_64
  • xorg-x11-proto-devel.noarch
  • sqlite-tcl.x86_64
  • sqlite-devel.x86_64
  • openssl.x86_64
  • crypto-utils.x86_64
  • openssl-devel.x86_64
  • libfontenc.x86_64
  • libfontenc-devel.x86_64
  • fontconfig.x86_64
  • fontconfig-devel.x86_64
  • libicu-devel.x86_64
  • freetype-devel.x86_64
  • libpng-devel.x86_64
  • libjpeg-turbo-devel.x86_64
  • libXext-devel.x86_64
  • libxcb-devel.x86_64
  • xcb-util.x86_64

Installing the packages went smoothly:

sudo yum install autoconf pkgconfig.x86_64 python26-pyudev.noarch python26-twisted.noarch sip.x86_64 python27-pyudev.noarch python27-twisted.noarch gcc flex bison xorg-x11-server-Xorg.x86_64 xorg-x11-server-devel.x86_64 xorg-x11-utils.x86_64 xorg-x11-proto-devel.noarch sqlite-tcl.x86_64 sqlite-devel.x86_64 openssl.x86_64 crypto-utils.x86_64 openssl-devel.x86_64 libfontenc.x86_64 libfontenc-devel.x86_64 fontconfig.x86_64 fontconfig-devel.x86_64 libicu-devel.x86_64 freetype-devel.x86_64 libpng-devel.x86_64 libjpeg-turbo-devel.x86_64 libXext-devel.x86_64 libxcb-devel.x86_64 xcb-util.x86_64

Step 2 — clone the Git repo to local drive:

git clone git://github.com/ariya/phantomjs.git
Cloning into ‘phantomjs’…
remote: Counting objects: 63695, done.
remote: Compressing objects: 100% (37/37), done.
remote: Total 63695 (delta 16), reused 0 (delta 0), pack-reused 63657
Receiving objects: 100% (63695/63695), 129.05 MiB | 4.08 MiB/s, done.
Resolving deltas: 100% (31013/31013), done.
Checking connectivity… done.

cd phantomjs

git checkout 2.1.1
Note: checking out ‘2.1.1’.
[…]
HEAD is now at d9cda3d… Set version to “2.1.1”

git submodule init
Submodule ‘3rdparty-win’ (https://github.com/Vitallium/phantomjs-3rdparty-win.git) registered for path ‘src/qt/3rdparty’
Submodule ‘qtbase’ (https://github.com/Vitallium/qtbase.git) registered for path ‘src/qt/qtbase’
Submodule ‘qtwebkit’ (https://github.com/Vitallium/qtwebkit.git) registered for path ‘src/qt/qtwebkit’

git submodule update
Cloning into ‘src/qt/3rdparty’…
Cloning into ‘src/qt/qtbase’…
Cloning into ‘src/qt/qtwebkit’…

Step 3 — Hack the QT build

It seemed that I needed to set some different flags for the qtbase build. It was not clear to me if this could be done with the build.py options, so I hacked the qt/qtbase/configure script.

vi src/qt/qtbase/configure

First off, I changed the settings of these two values near the top of the config file:

Then commented out part of the section around Werror, so that the build would not treat warnings as errors. The C++ macro options in the code will generate A LOT of errors, most of them from the flags defined in build.py. I tried the route of disabling those flags and ended up with more errors and more issues.. so changing the flags in the config was my next option:

[…]
#CFG_WERROR=auto
CFG_WERROR=no
[…]
#CFG_DEV=no
CFG_DEV=yes
[…]
warnings-are-errors|Werror)
# if [ “$VAL” = “yes” ] || [ “$VAL” = “no” ]; then
# CFG_WERROR=”$VAL”
# else
UNKNOWN_OPT=yes
# fi
;;
[…]

Step 4 — Build!

python build.py
—————————————-
WARNING
—————————————-

Building PhantomJS from source takes a very long time, anywhere from 30 minutes
to several hours (depending on the machine configuration). It is recommended to
use the premade binary packages on supported operating systems.

For details, please go the the web site: http://phantomjs.org/download.html.

Do you want to continue (Y/n)? Y

Step 5 — check the binary

Once the build has completed, you will find the binary to be built in the local directory bin/

ls -l bin/phantomjs
-rwxr-xr-x 1 root root 56736434 Feb 5 11:33 /usr/sbin/phantomjs

To complete the installation, you’ll need to replace the current phantomjs binary with the new one. To find the location if your current binary (if you have one), this should work:

whereis phantomjs
phantomjs: /usr/bin/phantomjs

Copy the new binary to that location and verify version:

cp bin/phantomjs /usr/bin/phantomjs
cp: overwrite ‘/usr/bin/phantomjs’? y

phantomjs -v
2.1.1

YOU ARE DONE!! It was just that easy
