[Axiom-developer] Summary of Install of axiom on FC3 and FC4

[Renaud . Rioboo]

Dear Axiom Gurus,

Thank you all for your help concerning the install of axiom under recent
Fedora versions.

It seems that Fedora enabled a kernel feature which randomizes memory for
security reasons and this is causing problems to run/build axiom. I used two
machines to test.

address@hidden>uname -a
Linux roamrr.rioboo.org 2.6.13-1.1526_FC4 #1 Wed Sep 28 19:15:10 EDT 2005 i686 
i686 i386 GNU/Linux
address@hidden>uname -a
Linux gate.rioboo.org 2.6.12-1.1378_FC3 #1 Wed Sep 14 04:24:31 EDT 2005 i686 
athlon i386 GNU/Linux


I Checked out the content of 

address@hidden>cat /proc/sys/kernel/randomize_va_space
1

If I turn off this by issuing 

echo 0 > /proc/sys/kernel/randomize_va_space

I can run the preinstalled version for FC3 and FC4 and compile the Cvs version
correctly. This has however the inconvenient that the feature is globally
turned off for the whole system. 

In FC4 there is a setarch command which disables randomization on a per
process basis. I was not able to find a way to find an equivalent under
FC3. Thus in FC4

address@hidden>setenv AXIOM 
/usr/local/Install/OpenAxiom/PrecompiledAxiom/axiom/mnt/linux
address@hidden>set path = ( $AXIOM/bin $path)
address@hidden>setarch `arch` -R axiom

works correctly with the advantage that you can run this without requiring a
global modification.

You can also compile the Cvs version of axiom by issuing

setarch àrch`-R make

to build the system.

I hope this will be of some help for other axiom users.

Regards,

                Renaud
