Problems regarding jhbuild

[Abishek Kumar <abishekkumar92 gmail com>]

Hey

I am facing difficulty in building the JHbuild from the below instruction page:

https://wiki.gnome.org/Newcomers/BuildGnome

I get the below error when i run the following command:

$jhbuild build adwaita-icon-theme dconf glib-networking gvfs libcanberra

*** Checking out vala *** [20/30]

git remote set-url origin git://git.gnome.org/vala

git remote update origin

Fetching origin

git rebase origin/0.34

Current branch 0.34 is up to date.

*** Configuring vala *** [20/30]

./autogen.sh --prefix /home/hulkbuster/jhbuild/install --disable-Werror --enable-vapigen --disable-static --disable-gtk-doc 

./autogen.sh: 10: ./autogen.sh: valac: not found

**Error**: You must have valac >= 0.12.0 installed

  to build vala. Download the appropriate package

  from your distribution or get the source tarball at

  http://download.gnome.org/sources/vala/

*** Error during phase configure of vala: ########## Error running ./autogen.sh --prefix /home/hulkbuster/jhbuild/install --disable-Werror --enable-vapigen --disable-static --disable-gtk-doc  *** [20/30]

  [1] Rerun phase configure

  [2] Ignore error and continue to build

  [3] Give up on module

  [4] Start shell

  [5] Reload configuration

  [6] Go to phase "wipe directory and start over"

  [7] Go to phase "clean"

  [8] Go to phase "distclean"

choice:

can anyone of you help me with this. I would really like to contribute to gnome from here on. Thanks in advance.

Best regards
