Excellent. How do I do it? This would be ideal: plain 32-bit procps for a 32-bit kernel plain 64-bit procps for a 64-bit kernel special 32-bit procps library for a 64-bit kernel Regular ppc gets #1, while ppc64 gets #2 and #3. > If you have a problem with common binaries (for the very > very very few apps that it even matters), you need to > talk with the application programers, since the changes > to apps like "top" are not forced on you by our decision > to execute 32-bit apps on our 64-bit kernel. Well, I'm the application programer in this case. There's a library too, in need of a stable ABI. http://procps.sf.net/ I can't find documentation for... How do I force gcc into 64-bit mode? How do I force gcc into 32-bit mode? How do I tell if a 32-bit build is meant for ppc64? Where do I install a 64-bit library? Where do I install a 32-bit library? How do I prevent a plain 32-bit lib from running on ppc64? Can I handle ppc64 and mips64 the same way? Coolness would be a thunking feature, so that a 64-bit library could provide 32-bit entry points. BTW, I could use an account on such a machine. Even a plain user account would be helpful. Reply to:

Citiraj: Nisam ja misao point, nego ti miješaš lončiće. Znači, imaš OS 64-bit, a većina aplikacija je 32-bit. 99.9% 32-bitnih aplikacija uredno radi u 64-bit OSu. 64-bit OS se najviše koristi zbog već navedenog razloga. Aplikacije koje su ti 64 bit, u TMu ti neće pisati da su 64-bit, nego ti jednostavno neće pisati da su 32, ako si shvatio poantu. (Sad sam na 32-bit OSu pa ne mogu 100% provjeriti tvrdnju, ali mislim da je tako) Ništa čudno, sve ti je u redu i nema razloga za brigu. Zašto je to tako, objasnio sam ti u samom startu, plus za 95% aplikacija nema previše smisla da se ponovo pišu za 64-bit OS, ponajviše iz razloga što nemaju nikakve dobiti samim time. Koristiš 8GB rama i jedini način da ih iskoristiš je da imaš 64-bit OS.
