Libdl

Libdl Copyright (C) 2009-2010 Dario Faggioli Release under GPL, version 2 (see COPYING) Use at your own risk.

ABOUT

Libdl provides what is needed to use the SCHED_DEADLINE scheduling policy and all its features from an userspace program. This is needed since the new system calls, flags, etc. that make it possible are not (yet? :-P) included in the standard library.

PREREQUISITES

The new interface is only implemented by kernels patched to support the SCHED_DEADLINE schedulign policy.

Instructions on how to download and compile such a kernel are available on the development Website of the project:

http://gitorious.org/sched_deadline/pages/Home

USAGE

To compile the library as a static or shared object:

$> make static or $> make shared or just $> make

To install in the default path (/usr/local/lib):

#> make install

To customize the install path change DESTPREFIX and DESTDIR in the Makefile.

To statically include the files in your project:

• copy dl_syscalls.h and dl_syscalls.c in your header and source folder;
• edit your Makefile so that targets where the new interface is used depends on dl_syscall.c;
• compile and install it as usual.
