I should probably describe the basic problem more clearly, I realize. The handling of RZ files by packlib uses the assumption that pointers fit into 32-bit ints, which is in general not true on 64-bit arches. But at least on AMD64, there is a way (Harald Vogt's patches, which are applied in Debian) to work around this. However the workaround only works when packlib is statically linked into an executable. So when linked from the libHbook.so plugin which is dynamically loaded at runtime, I don't think it could work at all. (Leaving aside the problem that doing so would require a libpacklib_pic.a file...) When statically linked from g2root and h2root it ought to be OK on amd64 though. It's also possible (I haven't checked) that libHbook.so re-implements reading RZ files independently of the Cernlib implementation in libpacklib and does so in a 64-bit clean way, in which case my objections would only apply to h2root and g2root. -- Kevin B.
