Hi Helmut,

Could you please post your complete emerge log?
Also, do earlier versions of itpp install fine
(4.0.3 say).

Thanks,
Markus

Created an attachment (id=149687) [details]
itpp-4.0.4 build log

Currently, I have version 4.0.3 installed.
I haven't changed gcc since then (still using version 4.2.3)

Created an attachment (id=149759) [details]
fix for linking problems

Could you please give the attached patch a spin!

The cause of your problems seems to be the fact that
you are compiling itpp without any blas support 
(any reason for this BTW?) which pulls in a template
that is not declared inline and therefore ends up
in the library leading to the symbol clash.

Thanks,
Markus

Hi Markus,

Thanks for the patch. It is indeed the problem of missing inline keyword in
this template specialisation and this is a regression in 4.0.4 version only
(4.0.3 is fine). I will fix this upstream so the next stable release will be
free of this bug. Could you please add this patch to the current ebuild in
portage?

Thanks!
/Adam

Hi Adam,

Thank you very much for looking into this and I've
just added the patch to portage cvs.

@Helmut:
Please wait an hour or so for the fix to propagate
to the mirrors.

Best,
Markus
