Package with support for 64-bits arch only

[Ghislain Vaillant <ghisvail@gmail.com>]

Dear all,

I am working on a package (Gadgetron), which does not support 32-bit builds for some reason. I contacted upstream about the issue but they actually do not care because the use case for 32-bit is, and I am quoting here, "asinine".

Is there a way to get the source package to be built only for architectures supporting 64-bits ? Or should I consider a different alternative ?

Cheers,

Ghis
