I'm trying to modify this macro
http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_count_cpus.m4
which attempt to get the number of CPUs in a system. I'd like to extend
it to cover Solaris, AIX and HP-UX.
It seems sensible to me to only do a test on a platform it will work on,
so I think thinking of something like
if `uname` = "HP-UX"
write test for HP-UX
fi
or I could check if __hpux__ is defined or not.
Can anyone show me how to modify the above autoconf macro to do the test
using either uname, a macro that the pre-processor defines, or other
that allows me to execute a bit of code on only one platform. method.
There's another macro I've seen used for determine cache sizes of
processors.
http://www.nongnu.org/autoconf-archive/ax_cache_size.html
which depends on the CPU being an x86 one, which it will often not be. I
don't fancy the task of trying to work out cache sizes for every
processor used on machines running Solaris, AIX or HP-UX, so will try to
modify that so it returns a sensible guess (say 1 MB) on processors it
does not know about. The test is causing a script to crash on HP-UX.
