Building trunk tracking ngx_pagespeed with PSOL synced to trunk

Most people will be fine using the binary distribution of PSOL to build ngx_pagespeed the standard way or [building PSOL from source synced to the tagged version] (https://github.com/pagespeed/ngx_pagespeed/wiki/Building-PSOL-From-Source) but if you want to use the latest PSOL source and build ngx_pagespeed against this source, you need to follow these instructions.

First build mod_pagespeed from source.

$ mkdir -p ~/bin
$ cd ~/bin
$ svn co http://src.chromium.org/svn/trunk/tools/depot_tools
$ export PATH=$PATH:~/bin/depot_tools
$ mkdir ~/mod_pagespeed
$ cd ~/mod_pagespeed
$ gclient config http://modpagespeed.googlecode.com/svn/trunk/src
$ gclient sync --force --jobs=1
$ cd src/
$ make AR.host="$PWD/build/wrappers/ar.sh" \
       AR.target="$PWD/build/wrappers/ar.sh" \
       BUILDTYPE=Release \
       mod_pagespeed_test pagespeed_automatic_test

(See mod_pagespeed: build from source if you run into trouble, or ask for help on the mailing list.)

Then build the pagespeed optimization library:

$ cd net/instaweb/automatic
$ make AR.host="$PWD/../../../build/wrappers/ar.sh" \
       AR.target="$PWD/../../../build/wrappers/ar.sh" \
       BUILDTYPE=Release \
       all

Check out ngx_pagespeed:

$ cd ~
$ git clone [email protected]:pagespeed/ngx_pagespeed.git

Check out ngx_pagespeed trunk-tracking branch specifically:

$ cd ~/ngx_pagespeed
$ git checkout trunk-tracking

Continue with the instructions given in the [building PSOL from source page] (https://github.com/pagespeed/ngx_pagespeed/wiki/Building-PSOL-From-Source) for downloading and building nginx.
