#
# Hints for the Cray XT4 Catamount/Qk system:
# cross-compilation host is a SuSE x86_64-linux,
# execution at the target with the 'yod' utility,
# linux.sh will run this hints file when necessary.
#
# cc.sh: compiles the code with the cross-compiler, patches main/exit/_exit
# (and traps signals) to be wrappers that echo the exit code.
#
# run.sh: runs the executable with yod and collects the exit status,
# and exits with that status.
#
# You probably should do the compilation in non-Lustre filesystem
# because Lustre does not support all the POSIX system calls, which may
# cause weird errors during the Perl build:
# 1182003549.604836:3-24:(super.c:1516:llu_iop_fcntl()): unsupported fcntl cmd 2
#
# As of 2007-Sep (pre-5.10) miniperl, libperl.a, and perl can be successfully
# built; no extensions are built.  It would be hard since Perl cannot run
# anything external (pipes, system(), backticks or fork/exec, or globbing)
# (which breaks MakeMaker, and confuses ext/util/make_ext).
#
# To build:
#
#   sh Configure -des
#   make perl
#
# "make install" won't work since it assumes file globbing (see above).
# You can try the following manual way:
#
# mkdir -p /opt/perl-catamount
# mkdir -p /opt/perl-catamount/include
# mkdir -p /opt/perl-catamount/lib
# mkdir -p /opt/perl-catamount/lib/perl5/5.36.3
# mkdir -p /opt/perl-catamount/bin
# cp *.h /opt/perl-catamount/include
# cp libperl.a /opt/perl-catamount/lib
# cp -pr lib/* /opt/perl-catamount/lib/perl5/5.36.3
# cp miniperl perl run.sh cc.sh /opt/perl-catamount/lib
#
# With the headers and the libperl.a you can embed Perl to your Catamount
# application, see pod/perlembed.pod.  You can do for example:
#
# cc -I/opt/perl-catamount/include -L/opt/perl-catamount/lib -o embed embed.c
# yod -sz 1 ./embed -le 'print sqrt(2)'
#
# You might want to have the run.sh execution wrapper around (it gets created
# in the Perl build directory) if you want to run the miniperl or perl in
# the XT4.  It collects the exit status (note that yod is run with "-sz 1",
# so only one instance is run), and possible crash status (bare yod does
# not collect the exit status).  For example:
#
#   sh /opt/perl-catamount/bin/run.sh /opt/perl-catamount/bin/perl -le 'print 42'
# 
# or if you are still in the build directory:
#
#   sh run.sh ./perl -le 'print 2*3*7'
#
# The cc.sh is a wrapper for the Catamount cc used when building Perl
# (and before that, when running Configure), it arranges for the main()
# exit(), _exit() to be wrapped so that the exit/crash status can be
# collected (by run.sh).
