64-bit link

hello

first: how knows how i can force my compliter to compile and link the programs (from source) with the 64-bit libraries???? :blink:

second: i would like to compile them with diferent parameters (like -O3) how do i do it... there is a lot of Makefiles for each program... so i suppose that it is not posible to change this in all the files... <_<

third: do i need the 32-bit libraries???? what will happens if i copy the files for /lib64 to /lib???? so i will overwrite the 32 bit libraries????

1. If you are running 64bit kernel, then source will use 64bit libraries to compile
2. Don't understand or don't know
3. Yes, you will need 32bit libraries, as lots of apps, and even the KDE/Gnome themselves, rely and need 32bit libraries, and having a 64bit system/OS installed doesn't mean you are running "clean" 64bit system.

is there any way to make it a 64-bit clean system?

Probably, with something like Gentoo, with Stage 1, that is compiling your own kernel, and then the rest. Myabe with Slack it's also possible.

As far as compiling things with different flags, just pass the command line CFLAGS and USE options to the compiler. CFLAGS="-march=amd64 -O3" make && CFLAGS="-march=amd64 -O3" make install, for example. Should work all right. If not, let me know.

Yes, Gentoo can get you a clean 64-bit system. Just install it with the use flag "-multilib". Tons of instructions are out there.

Slackware has never had an x86_64 version. I only wish they did.

i try to ask the ppl in slackware about a 64-bit vertion but i get no answer

As far as I have ever heard, Slackware has no thoughts of creating a 64 bit version.
