The procedure on this page describes how to build and configure Lustre code in a development environment. It assumes that you have:
- Checked out Lustre source code from CVS (see Accessing Lustre Code).
- Obtained an unmodified kernel source supported by the version of Lustre you have checked out (supported kernel sources can be found at http://downloads.lustre.org/public/kernels/).
Configuring and Building Lustre
To configure and build Lustre, follow these steps:
1. Run the autogen script. The autogen script performs a few checks and then bootstraps the build system using the GNU automake and autoconf functions.
$ sh autogen.sh Checking for a complete tree... checking for automake-1.7 1.7.8... found 1.7.9 checking for autoconf 2.57... found 2.59 ... running autogen for liblustre...
2. Apply Lustre patches to your Linux kernel sources. For instructions, see Applying Lustre Patches to a Kernel.
3. Run configure to set up your system to compile the Lustre code. Configure performs extensive checks of the underlying system and kernel and then produces makefiles.
Note: Replace /path/to/linux with the path to your patched kernel source (for example, /tmp/kernels/linux-2.6.18-128.1.1)
$ ./configure --with-linux=/path/to/linux checking build system type... i686-redhat-linux-gnu checking host system type... i686-redhat-linux-gnu checking target system type... i686-redhat-linux-gnu ... LLCFLAGS: -g -Wall -fPIC
4. Type 'make' to build Lustre.
$ make ...
5. Run lustre/tests/llmount.sh to initiate a loopback-based Lustre mount for local testing. Run lustre/tests/llmountcleanup.sh to clean up the loopback mount (reversing the actions of the previous script). Please see Running_Lustre_Tests_For_Developers for additional information.
