Configuring the Build
The Configure Script
Download the bzipped file on the Bluegene/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 - 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 -rwxr-xr-x 1 hnaik users 1444183 2009-01-23 17:03 BGP-exp-ION-zImage.elf -rwxr-xr-x 1 hnaik users 10423112 2009-01-23 17:03 BGP-ION-ramdisk.elf -rwxr-xr-x 1 hnaik users 10423988 2009-01-23 17:03 BGP-ION-ramdisk-for-CNL.elf -rw-r--r-- 1 hnaik users 132 2009-01-23 17:03 bgp-ion-ramdisk-passwd.txt -rwxr-xr-x 1 hnaik users 1351583 2009-01-23 17:08 BGP-ION-zImage.elf
