RE: FW: ../src/liboctinterp.so: undefined reference to `__cxa_guard_acquire'

[Letizia MAZZURCO]

Hi David,

My machine is a Red Hat Enterprise Linux WS release 3 (Taroon Update 5) :

address@hidden suitesparse]# uname -a
Linux CTNLS074 2.4.21-32.ELsmp #1 SMP Fri Apr 15 21:17:59 EDT 2005 i686 i686
i386 GNU/Linux 

Can I install a pre-built Octave 2.9 (Fedora or debian) on this system ?
If yes ....where I can download it ?

Thanks a lot.
Regards,

Letizia M.

You don't have this  problem with g77 3.2.3 building Octave as the blas
embedded in cholmod was also built with g77 3.2.3. However you then have an
issue of linking the C++ 4.3.0 compiled code with the g77 3.2.3 compiled
code.. You have to compile everything (even the external
libraries) with a consistent set of compilers

Why do you need to compile Octave at all? As you've noticed it is a complex
process due to the large number of dependencies. Why not use a Fedora or
debian based system and use the Octave 2.9 versions that are pre-built
(correctly) for these systems..
