Configuring the Build

The Configure Script

Download the bzipped file on the Blue Gene/P login node. Extract the sources by using:

$ tar xjf ZeptoOS-V20-V1R3M0-beta-20090401161133.tar.bz2 

Change to the BGP top directory using:

$ cd BGP/

Then you can use the configure script to set the system tools path to default using:

$ ./configure

In order to configure the site specific paths using the tool use:

$ ./configure --edit

Building ZeptoOS V2.0

Typing make help will bring up the following menu:

[MENU]

make                       - Prepare Zepto kernel and ramdisk images

make bgp-ion-ramdisk-cnk   - Rebuild ION ramdisk for CNK
make bgp-ion-ramdisk-cnl   - Rebuild ION ramdisk for CNL

make bgp-ion-linux         - Simply use recent built or prebuilt ION kernel (no kernel rebuild)
make bgp-cn-linux          - Rebuild CN ramdisk and merge with recent built or prebuilt CN kernel objs

make bgp-ion-linux-build   - Rebuild ION kernel
make bgp-cn-linux-build    - Rebuild CN kernel objs and CN ramdisk, then merge them into CN Kernel

make bgp-all-pkg-smart     - Build packages from the prebuilt binaries
make bgp-all-pkg-rebuild   - Rebuild all packages from source

To start using the default built binaries simply type:

$ make

This will copy all the required kernel and ramdisk images to the top level directory.

Examining the Build Directory

If the build was successful, one should be able to see the following new files either rebuilt from sources or copied from their prebuilt locations:

$ ls -l
-rwxr-xr-x  1 hnaik users  8629983 2009-01-23 17:16 BGP-CN-zImage-with-initrd.elf
