Unable to build gnome-builder using JHBuild

Question

I am trying to build gnome-builder code on Ubuntu 12.04 using JHBuild, but JHBuild is giving some errors:

1) on running jhbuild sanitycheck

checkout root (~/jhbuild/checkout) is not writable
Could not find DocBook XML DTD V4.1.2 in XML catalog
Could not find DocBook XSL Stylesheets in XML catalog

I have tried to install all possible dependencies I could.

2) Also jhbuild sysdeps --install shows:

list of dependencies ..
jhbuild sysdeps: Don't know how to install packages on this system

3) When I try to build it as shown below:

jhbuild -m gnome-world build gnome-builder

it shows:

jhbuild build: failed to parse /usr/share/jhbuild/modulesets/gnome-apps-3.20.modules: [Errno 2] No such file or directory: u'/usr/share/jhbuild/modulesets/gnome-apps-3.20.modules'

I have pasted sample jhbuildrc file in home dir as earlier it was showing

unable to load config file ~/.jhbuildrc not found

Answer 1

I hope you followed manual how to install JHBuild. After

$ jhbuild sanitycheck

it seems like there is a problem with ~/jhbuild/checkout. Run

mkdir ~/jhbuild/checkout

if it not exists, and

sudo chmod -R 777 ~/jhbuild/checkout

to change the permmission, if necessary.

If official Ubuntu docbook-xml and docbook-xsl packages are already installed, another error can be probably removed by installing xmlto

sudo apt-get update
sudo apt-get install xmlto
