Release Feb. 15th

Where will I put code and screenshots?

• http://svn2.assembla.com/svn/Seneca_Hera_Try_Server_Setup/buildbot-configs/ - Buildbot configs (look for "cairo")
• http://matrix.senecac.on.ca/%7Eazambran/mozilla/cairo/ - Archived files
• http://matrix.senecac.on.ca/%7Eazambran/mozilla/screenshots/ - Screenshots (look for "cairo" in the filenames)

What has been released this week:

• master.cfg - It builds Cairo and runs automated tests on one linux machine
• buildbot-status-cairo.jpg - After build #8 (no tests at this point)
• Buildbot:Cairo-results.tar.gz - After build #11 (tests were run)

Steps to meet requirements

• sudo apt-get install buildbot
• sudo apt-get install git-core //This is to get the version control that cairo uses, it is called GIT

Steps to make it happen

• buildbot create-master ~/cairomaster
• Put the master.cfg to the the created master
• buildbot create-slave ~/cairoslave localhost:9876 cairoslave
• buildbot start ~/cairomaster
• buildbot start ~/cairoslave
• firefox http://localhost:8020 //This is to be able to see the results of the build

Problems

• The first time the command GIT CLONE works because there is nothing before that execution but the second run should be an update instead of a checkout. What could be the proper GIT command to have as the step?
• I need to do SUDO MAKE INSTALL, but this requires user's input which breaks the automated concept. What could be the right step?

Build Cairo manually

• mkdir cairo & cd cairo
• git clone git://git.cairographics.org/git/pixman
• git clone git://git.cairographics.org/git/cairo
• cd pixman && ./autogen.sh
• ./configure
• make
• make install //I have a problem can I set up buildbot to use SUDO??

         make[2]: Entering directory `/home/armen/sandbox/cairo2/pixman/pixman'

• sudo make install

Running the tests and getting an index.html file with them

• make test //takes long time
• cd test && make html
• firefox index.html
