CLFS is the recommended book you have to follow to build a 64 bit system even if you have a 64 bit host and a 64 bit target. > My question is, what if I have a 64bit processor and I want to compile LFS > for that machine (building toolchain on that machine). A 64 bit processor (AMD64) can run a 32 bit system. You won't have much performance boost if you use a 64 bit one. The big difference is if you have more than 4 GB of physical RAM. > If I follow the instructions of LFS and BLFS team and install a package > (mysql for example) the configure script will use optimizations for 64bit > or I have to do some configuration manually (setting machine tripplet, > CCFLAGS .....) Don't use any particular flag. If you run a 32 bit system you can execute only 32 bit apps. It should be good, anyway. I suggest you go with 32 bit system and apps. --Luca -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
