Compiling PhantomJS 2.0 on an odroid U3

The title says it all… c++ compilation fun times!

As I was working on a project to selectively use Unblock Us on my network devices, I wanted to host the whole thing in my odroid… but compiling it right out of the box didn’t work for me. Also, for some reason a precompiled binary I found at community.scaleway.com (now dead) didn’t work for me. Doing this

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.0.0-source.zip
unzip phantomjs-2.0.0-source.zip;
cd phantomjs-2.0.0
nohup ./build.sh --confirm > build.sh.out 2> build.sh.err &

Took a whole a lot of time and eventually failed with a bunch of cryptic errors… but when I checked the build.sh.err file, the first one I found is

floatmath.cpp:44:5: warning: unused parameter ‘argv’ [-Wunused-parameter]
g++: error: unrecognized command line option ‘-msse2’
make: *** [sse2.o] Error 1

It makes sense, as SSE2 is an extension that’s not available on ARM… then I ran

find src -type f -print0 | xargs -0 sed -i 's/-msse2//g'

I tried compiling again, but it failed… and the problem was pretty stupid (and it took me a while to figure it out)… the previous .o files were still around, so the make process wasn’t building them again… sooo I completely deleted the folder, unzipped the file, removed the msse2 flag and this time it worked flawlessly!

Here are all the steps in an easy-to-copy format

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.0.0-source.zip
unzip phantomjs-2.0.0-source.zip<br />cd phantomjs-2.0.0
find src -type f -print0 | xargs -0 sed -i 's/-msse2//g'
nohup ./build.sh --confirm > build.sh.out 2> build.sh.err &

Just be prepared for it to last a while. If you want to just use my version, you can find it here (it includes the sources and the build output).

You can retrieve it by doing

curl -OL https://github.com/g3rv4/phantomjs-v2.0.0-odroidu3/raw/master/phantomjs-2.0.0.compiled.tgz.000
curl -OL https://github.com/g3rv4/phantomjs-v2.0.0-odroidu3/raw/master/phantomjs-2.0.0.compiled.tgz.001
curl -OL https://github.com/g3rv4/phantomjs-v2.0.0-odroidu3/raw/master/phantomjs-2.0.0.compiled.tgz.002
cat phantomjs-2.0.0.compiled.tgz.00? > phantomjs-2.0.0.compiled.tgz
tar -xzf phantomjs-2.0.0.compiled.tgz

The executable file is phantomjs-2.0.0/bin/phantomjs
