steps taken to build phantomjs on ppc64le

The phantomjs project uses a docker container to perform the build. The instructions say:

$ git clean -xfd .
$ docker run -v $PWD:/src debian:wheezy /src/deploy/docker-build.sh

the script is here [1]

However, I could not build a wheezy container for Debian:

[hamzy@pkvmci853 phantomjs]$ sudo su -
[root@pkvmci853 ~]# mkdir /wheezy-root
[root@pkvmci853 ~]# debootstrap --arch=powerpc wheezy /wheezy-root/ http://ftp.debian.org/debian/

Building a Jessie container did work:

[hamzy@pkvmci853 phantomjs]$ sudo su -
[root@pkvmci853 ~]# mkdir /jessie-root
[root@pkvmci853 ~]# debootstrap --arch=ppc64el jessie /jessie-root/ http://ftp.debian.org/debian/

Running the commands in the above script ran into a problem:

Okay, so much for self building! The docker images are located here [2].

Wheezy seems to be called oldstable-backports. This is probably not a good sign. The next revision, Jessie, also exists.

[hamzy@pkvmci853 phantomjs]$ sudo docker pull ppc64le/debian:oldstable-backports

[hamzy@pkvmci853 phantomjs]$ sudo docker pull ppc64le/debian:jessie

The script to do a docker build here [3] does not work for ppc64el. I created a new version for testing:

The next problem is that the master version in git does not support the docker build anymore:

We removed it because we no longer need bundled submodules (QtBase and QtWebKit). We are still working on the updated instruction how to build PhantomJS from master. But you always can checkout tag 2.1 and build it.

from here [4]

So, checking out the project like:

[hamzy@pkvmci853 ~]$ git clone https://github.com/ariya/phantomjs.git
[hamzy@pkvmci853 phantomjs]$ git checkout 2.1
Branch 2.1 set up to track remote branch 2.1 from origin.
Switched to a new branch '2.1'
[hamzy@pkvmci853 phantomjs]$ git am ~/0001-hamzy-docker-build-ppc64el.patch
Applying: hamzy docker-build-ppc64el

And running the build like:

[hamzy@pkvmci853 phantomjs]$ sudo docker run -v $PWD:/src -it --privileged --name phantomjs_ppc64el docker.io/ppc64le/debian:oldstable-backports /src/deploy/docker-build-ppc64el.sh
...
Copying the executable...
-rwxr-xr-x. 1 root root 78394384 Jun 21 04:04 bin/phantomjs

Finished.
...

...

Comes with the next two problems. 1) The program is not being built for 64-bit code and 2) The libstdc++ libraries are slightly newer than what exists on CentOS7.

Trying a backlevel gcc:

root@bdd8cc64c5ba:/# apt-get install -y build-essential g++-4.8 gcc-4.8 git flex bison gperf python ruby git libfontconfig1-dev
root@bdd8cc64c5ba:/# update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-4.9 10

root@bdd8cc64c5ba:/# gcc --version
gcc (Debian 4.8.4-1) 4.8.4

Came with the following problem during the build:

...
gcc: error: unrecognized command line option '-fstack-protector-strong'
...
OpenSSL support cannot be enabled due to functionality tests!
 Turn on verbose messaging (-v) to /root/build/src/src/qt/qtbase/configure to see the final report.
 If you believe this message is in error you may use the continue
 switch (-continue) to /root/build/src/src/qt/qtbase/configure to continue.
ERROR: Failed to build PhantomJS! Configuration of Qt Base failed.
...

The fix is to remove that C flag from the defaults.

root@4fb1f5d4dc0b:/openssl-1.0.1t# dpkg-buildflags --get CFLAGS
-g -O2 -fstack-protector-strong -Wformat -Werror=format-security
root@4fb1f5d4dc0b:/openssl-1.0.1t# (export DEB_CFLAGS_SET=$(dpkg-buildflags --get CFLAGS | sed 's/-fstack-protector-strong//'); dpkg-buildflags --get CFLAGS)
-g -O2  -Wformat -Werror=format-security

Update the patch for the new script file.

And run the script:

The next step was to build a source tarball for tripleo-ui-deps:

Apparently, phantomjs has been broken out of tripleo-ui-deps tarball into its own package phantomjs-1.9.7-3.el7 and of course it does not build on ppc64le.

...

One of the sub-packages of phantomjs is breakpad which is located here.

Trying to build it locally results in:

There already are two bugs written against breakpad to support PowerPC.
