gcc and bytes

xerxes2 · 2005-03-25 22:44:22

Two questions:

1. Where does Arch has it's gcc settings? I know about makepkg.conf but I mean other than that.

2. How do you count bytes when using KB and MB.

like 878687834 Bytes = 878687834 /1024 KB , and
8686876784847648 Bytes = 8686876784847648 /(1024**2) MB

or is it wrong? :?

I think your conversions are correct.

1 KB = 1024 Bytes
1 MB = 1024 KB = 1024 x 1024 Bytes

Not sure what gcc settings you're looking for..

gcc settings? I think they're compiled in (try gcc --version... I think it spits off a whole mess of crap)
you can also check in.... hmmm /usr/lib/i686-gcc-something, I can't recall the exact, but it has a whole mess of stuff there - like where std include files are....

hello phrak,
yes I thougfht of that after i posted, that there are some compiled in settings that works if you don't specify it some other way,

Edit: couldn't find anything in the PKGBUILD,
or is gcc falling back on the same settings that itself was compiled with?

what specifically are you looking for? maybe that will help?

xerxes2 · 2005-03-26 00:10:21

these are from makepkg.conf

export CARCH="i686"
export CHOST="i686-pc-linux-gnu"

# Pentium Pro/Pentium II/Pentium III+/Pentium 4/Athlon exclusive (binaries
# will use the P6 instruction set and only run on P6+ systems)
export CFLAGS="-march=i686 -O2 -pipe"
export CXXFLAGS="-march=i686 -O2 -pipe"

where does these come from if I'm not sourcing that file?

makepkg is a script. It sources makepkg.conf. I don't know if it answer your question.

you want to know the defaults for -march and things like that?

if depends on the option... -O is for optimization... if it's not there, it just doesn't do it... same with -pipe i think

as for -march, i'd assume if unspecified it uses what system it's running on

i think autoconf grabs it from running config.guess. Same with host and target..
not positive, but that is my initial impression.

yes, that was what I meant cactus,

what settings is used when compiling without makepkg,

Arch Linux
