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 attachment 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 attachment 149759 [details, diff] 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
(In reply to comment #3) > Could you please give the attached patch a spin! 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
Just FYI: http://itpp.svn.sourceforge.net/viewvc/itpp?view=rev&revision=1550 http://itpp.svn.sourceforge.net/viewvc/itpp?view=rev&revision=1551 /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
