Subject: Compiling libsepol with -fPIC instead of -fpic
Date: Wed, 15 Nov 2006 00:45:25 -0600

Hi,

        I've had reports of packages filing to compile on SPARC
 hardware when linked with  libsepol1 which was compiled with
 -fpic. We seem to be hitting the global offset table size limit;
,----[ GCC manual ]
| `-fpic'
|      Generate position-independent code (PIC) suitable for use in a
|      shared library, if supported for the target machine.  Such code
|      accesses all constant addresses through a global offset table
|      (GOT).  The dynamic loader resolves the GOT entries when the
|      program starts (the dynamic loader is not part of GCC; it is part
|      of the operating system).  If the GOT size for the linked
|      executable exceeds a machine-specific maximum size, you get an
|      error message from the linker indicating that `-fpic' does not
|      work; in that case, recompile with `-fPIC' instead.  (These
|      maximums are 8k on the SPARC and 32k on the m68k and RS/6000.  The
|      386 has no such limit.)
`----

        Simply recompiling with -fPIC corrects the problem.
