amd64 vs IA32 linux versions: can programs be incompatible
I was trying to install a progtam (T-coffee a program aligning DNA and proteins sequences) on my SUSE 10.0. I followed the instructions coming with the program but during the installation I noticed that many lines scrolling quickly in the window indicating errors and warnings. I couldn`t catch their meaning. There was no error message at the end of the process. The binary file obtained at the end didn`t work. The same happened for another program (dialing 2.2). My questions are:
1. My linux is an AMD64 version. I didn`t know what I was doing during linux installation but I don`t recall any possible choice. I think Suse 10.0 automatically chose AMD64 (my processor is indeed and AMD64). Is it possible that those programs are incompatible with my linux version?
2. Could I force the installation of a 32 bit version?
3. any other suggestion to make them work?
