I want to set up a compile tool-chain for my Raspberry pi B and follow the guide :
http://wiki.gentoo.org/wiki/Raspberry_Pi_Quick_Install_Guide
But,when I run :
# crossdev -S -v -t armv6j-hardfloat-linux-gnueabi, it failed in the stage2 of glibc's compiling:

I searched the google for a long time,but nothing hlep(or I missed) . Need help ! :oops:

There is an error in the CFLAGS handling when crossdev compiles for the target. binutils and gcc are compiled for the host and configure uses the CFLAGS from make.conf, in your case -march=native -pipe -O2 -fno-strict-aliasing. configure of the glibc's ebuild uses the same CFLAGS when it tries to find out which object file suffix armv6j-hardfloat-linux-gnueabi-gcc generates. So the error occurs during the execution of armv6j-hardfloat-linux-gnueabi-gcc -march=native -pipe -O2 -fno-strict-aliasing. -march=native does not work for cross-compilers because the compiler on the host cannot check the target CPU.

Here is the workaround. In the second step enter the CFLAGS value of the target.
  1. crossdev --stage2 -S -v -t armv6j-hardfloat-linux-gnueabi
  2. CFLAGS="-O2 -pipe -march=armv6j -mfpu=vfp -mfloat-abi=hard" crossdev --stage3 -S -v -t armv6j-hardfloat-linux-gnueabi
  3. crossdev --stage4 -S -v -t armv6j-hardfloat-linux-gnueabi
These three steps worked for my Dockstar (armv5) and Cubox (armv7).

This worked for me when I was creating an armv6 toolchain for my Raspberry Pi:

Code:

USE="-* nocxx" crossdev -S --target armv6j-hardfloat-linux-gnueabi


gcc version:

Code:

armv6j-hardfloat-linux-gnueabi-gcc --version

armv6j-hardfloat-linux-gnueabi-gcc (Gentoo 4.5.4 p1.0, pie-0.4.7) 4.5.4

I suggest you make a list of all the software you're going to need on your Pi and compile it straight away. Crossdev breaks every time I update @world.

crossdev is way to complicated for something as simple as crosscompiling.

What's the easiest way to cross compile? For different arch and or slower machine?

thanks

Maybe you have in your CFLAGS no architecture specific flags like -march/-mtune or a fixed version of crossdev. The error depends on CFLAGS not on USE flags in crossdev-20120721.

It works ~ Thank you so much ! .I think this should be writen into the guide page :D :o :P . Now , I can enjoy my Pi with gentoo running inside ~

Hmm , I know not too much in cross-compiling. I think crossdev is a really smart way to set up a toolchain . :wink: :wink:
