------------------------+---------------------------------------------------
My recently updated prereq-0.4 #7021 has a minor portability issue, which
existed in version 0.3 too. If run on HP-UX, which the 'uname' command
does not support the -p option needed to get the processor, so generates
the following message:
{{{
Starting prerequisite check.
Machine: HP-UX hpbox B.11.11 U 9000/785 2016698240 unlimited-user license
uname: illegal option -- p
usage: uname [-amnrsvil] [-S nodename]
}}}
The reason is quite simple. The code which checks for an operating system
which is not Solaris SPARC uses this:
{{{
elif [ `uname` = "SunOS" -a "`uname -p`" != "sparc" ]; then
echo "Building or using Sage on non-Sparc Solaris is tricky and
not supported"
echo "at the moment. It is possible, but you should be well aware
that"
echo "some things do not work. Support for Solaris"
echo "on non-SPARC hardware is actively being worked on."
echo "To get past this message, export the variable SAGE_PORT to"
echo "something non-empty."
exit 1
elif [ `uname` = "HP-UX" ]; then
}}}
It would better be changed to
{{{
elif [ `uname` = "SunOS" ]; then
# The -p option to 'uname' is not portable (HP-UX does not support
it for example)
# So it is safer to test for Solaris first, then test for the
processor with the
# -p option if necessary.
if [ "`uname -p`" != "sparc" ]; then
echo "Building or using Sage on non-Sparc Solaris is tricky and
not supported"
echo "at the moment. It is possible, but you should be well
aware that"
echo "some things do not work. Support for Solaris"
echo "on non-SPARC hardware is actively being worked on."
echo "To get past this message, export the variable SAGE_PORT
to"
echo "something non-empty."
exit 1
fi
elif [ `uname` = "HP-UX" ]; then
}}}
which would then only use the -p option on Solaris.
I'll update this at one point in the future. I expect I'll get some
feedback from the prereq-0.4, so I'll created a 0.5 at some time in the
future.
This does not actually terminate the build process on HP-UX, so even for a
port, it is not a big issue.
