Building Dependencies

Running ./buildall.sh in the top level directory produces the binaries for the current versions of all packages. This will likely take several hours the first time you run it. If you rerun the script, it checks the build and check directories for preexisting artifacts and only regenerates them if not present.

If you want to build all versions of all packages, you can set the environment variable BUILD_HISTORICAL=1. Be warned this will take a long time.

BUILD_HISTORICAL=1 buildall.sh

Sources

By default, the sources for the different packages are downloaded from an S3 bucket provided by Cloudera. If desired, it's possible to download the exact version of the package and simply move it to the source directory.

For example, if you want to download the gcc source manually, find the gcc-4.9.2.tar.gz archive and copy it to source/gcc. If the file is present it will not be downloaded again.

Building a Specific Package

To build a specific package run:

./build.sh package package.version

for example:

./build.sh python 2.7.10

Its possible as well to build several packages at once.

./build.sh python 2.7.10 llvm 3.3-p1

Here, the arguments are package version pairs.

Mac OS X

To build on Mac we cannot use a custom GCC, so we have to use the system compiler:

SYSTEM_GCC=1 DEBUG=1 ./buildall.sh
