Release

Requirements

• buildbot (I am using 0.7.5)
• twisted (I am using 2.5.0)
• Git (I am using 1.5.3.6)

Mar. 7th

• The steps to build on Mac have been added to Seneca Hera Try Server Setup/buildbot-configs/

and the blog post explaining a lot of details about how much has been done is here: (Sess14-Buildbot on Cairo)

1. svn co http://svn2.assembla.com/svn/Seneca_Hera_Try_Server_Setup/buildbot-configs/cairomaster/
2. buildbot create-slave ./cairoslave localhost:9876 macslave slavepassword (change macslave for linuxslave when trying to run in Linux)
3. buildbot start cairomaster
4. buildbot start cairoslave
5. firefox http://localhost:8020 //OR open it with any browser

Problems

• A lot of problems when trying to build on MacOS are mentioned here: Sess14-Buildbot on Cairo
• 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 have decided to remove the checked out code and checkout the trunk before each build

• I need to do SUDO MAKE INSTALL, but this requires user's input which breaks the automated concept. What could be the right step?

Used ./configure --prefix=/path/to/somewhere to avoid building somewhere where I require to have sudo privileges

Notes

These notes are for learning purposes and documentation

Feb. 15th release

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

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' test -z "/usr/local/lib" || /bin/mkdir -p "/usr/local/lib" /bin/bash ../libtool --mode=install /usr/bin/install -c 'libpixman-1.la' '/usr/local/lib/libpixman-1.la' /usr/bin/install -c .libs/libpixman-1.so.0.9.6 /usr/local/lib/libpixman-1.so.0.9.6 /usr/bin/install: cannot remove `/usr/local/lib/libpixman-1.so.0.9.6': Permission denied make[2]: *** [install-libLTLIBRARIES] Error 1

• sudo make install //I had to use SUDO
• whereis libpixman-1
• cd ../cairo && ./autogen.sh
• ./configure
• make
• make install //the same problem with SUDO

make[2]: Entering directory `/home/armen/sandbox/cairo2/cairo/src' test -z "/usr/local/lib" || /bin/mkdir -p "/usr/local/lib" /bin/bash ../libtool --mode=install /usr/bin/install -c 'libcairo.la' '/usr/local/lib/libcairo.la' /usr/bin/install -c .libs/libcairo.so.2.14.0 /usr/local/lib/libcairo.so.2.14.0 /usr/bin/install: cannot create regular file `/usr/local/lib/libcairo.so.2.14.0': Permission denied

• 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
