Re: [Bkchem-user] bkchem on linux ... questions

[Beda Kosata]

Hi Rochus,
I am sorry for writing so late.
I did some experiments with binary release for bkchem and found that it 
is nearly impossible. The problem is in different version of shared 
libraries on different systems.
The solution to this would be either to provide binaries for different 
systems built on the respective systems. This would, however mean that I 
would have to build a binary for Redhat 9.0 on Redhat 9.0, so it would 
obviously not solve the problem with the boxes :)
The other solution is to package every dependency, dependency of 
dependency (and so forth, ad nauseam) with bkchem, but this would in 
fact mean building a custom linux distribution (X is one of the 
dependencies :) without being sure it would work anyway :(

I am sorry that I have no good news :(

        Cheers
                BEDA
