README.linux - Perl version 5 on Linux systems
DESCRIPTION
This document describes various features of Linux that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
Experimental Support for Sun Studio Compilers for Linux OS
Sun Microsystems has released a port of their Sun Studio compilers for Linux. As of November 2005, only an alpha version has been
released. Until a release of these compilers is made, support for compiling Perl with these compiler experimental.
Also, some special instructions for building Perl with Sun Studio on Linux. Following the normal "Configure", you have to run make as
follows:
LDLOADLIBS=-lc make
"LDLOADLIBS" is an environment variable used by the linker to link modules "/ext" modules to glibc. Currently, that environment variable
is not getting populated by a combination of "Config" entries and "ExtUtil::MakeMaker". While there may be a bug somewhere in Perl's
configuration or "ExtUtil::MakeMaker" causing the problem, the most likely cause is an incomplete understanding of Sun Studio by this
author. Further investigation is needed to get this working better.

README.irix - Perl version 5 on Irix systems
DESCRIPTION
This document describes various features of Irix that will affect how Perl version 5 (hereafter just Perl) is compiled and/or runs.
Building 32-bit Perl in Irix
Use
sh Configure -Dcc='cc -n32'
to compile Perl 32-bit. Don't bother with -n32 unless you have 7.1 or later compilers (use cc -version to check).
(Building 'cc -n32' is the default.)
Building 64-bit Perl in Irix
Use
sh Configure -Dcc='cc -64' -Duse64bitint
This requires require a 64-bit MIPS CPU (R8000, R10000, ...)
You can also use
sh Configure -Dcc='cc -64' -Duse64bitall
but that makes no difference compared with the -Duse64bitint because of the "cc -64".
You can also do
sh Configure -Dcc='cc -n32' -Duse64bitint
to use long longs for the 64-bit integer type, in case you don't have a 64-bit CPU.
If you are using gcc, just
sh Configure -Dcc=gcc -Duse64bitint
should be enough, the Configure should automatically probe for the correct 64-bit settings.
About Compiler Versions of Irix
Some Irix cc versions, e.g. 7.3.1.1m (try cc -version) have been known to have issues (coredumps) when compiling perl.c. If you've used
-OPT:fast_io=ON and this happens, try removing it. If that fails, or you didn't use that, then try adjusting other optimization options
(-LNO, -INLINE, -O3 to -O2, etcetera). The compiler bug has been reported to SGI. (Allen Smith <easmith@beatrice.rutgers.edu>)
Linker Problems in Irix
If you get complaints about so_locations then search in the file hints/irix_6.sh for "lddflags" and do the suggested adjustments. (David
Billinghurst <David.Billinghurst@riotinto.com.au>)
Malloc in Irix
Do not try to use Perl's malloc, this will lead into very mysterious errors (especially with -Duse64bitall).
Building with threads in Irix
Run Configure with -Duseithreads which will configure Perl with the new Perl 5.8.0 "interpreter threads", see threads.
The old Perl 5.005 threads is obsolete, unmaintained, and its use is discouraged. If you really want it, run Configure with the
-Dusethreads -Duse5005threads options as described in INSTALL.
For either thread model and for Irix 6.2, you have to have the following patches installed:
1404 Irix 6.2 Posix 1003.1b man pages
1645 Irix 6.2 & 6.3 POSIX header file updates
2000 Irix 6.2 Posix 1003.1b support modules
2254 Pthread library fixes
2401 6.2 all platform kernel rollup
IMPORTANT: Without patch 2401, a kernel bug in Irix 6.2 will cause your machine to panic and crash when running threaded perl. Irix 6.3
and later are okay.
Thanks to Hannu Napari <Hannu.Napari@hut.fi> for the IRIX
pthreads patches information.
