Raspberry pi 3 32bit - distcc - crossdev - MacOSX

[vhristev]

Hey Guys ,

Anyone offload his Pi with hackintosh. I want to offload it on my Intel Quad Xeon W3520

I'm new to cross compiling and i stuck on OS X machine. Back in the days i had chain of ~30 machines but all of them was same arch.

Anyone did a MasOSX distcc and crossdev for ARM ?

Here is where I'm stuck:

Wiki i follow:
https://wiki.gentoo.org/wiki/Raspberry_Pi/Cross_building#crossdev

vhristev,

You set up distcc on the heavy lifter as a helper. The symlinks you posted are not required for portage to use distcc.
You install distcc on the Pi anh set up the /etc/distcc/hosts file. distccd only runs on the helper.

If crossdev worked you will have /usr/armv7a-hardfloat-linux-gnueabi/ which is your armv7a-hardfloat-linux-gnueabi target directory.
Should you feel the need to pure cross compile stuff, it will install here.

You will also have /usr/bin/armv7a* which is your cross compile kit.

When your Pi distributes work, because you set the FEATURES in its make.conf, it should just work.

Testing the cross compiler on its own is a bit more difficult.

In /usr/armv7a-hardfloat-linux-gnueabi/etc/portage, fix the profile symlink. The embedded profile is not useful.
Set up /usr/armv7a-hardfloat-linux-gnueabi/etc/portage/make.conf That's the make.conf that will be used for pure cross (not cross distcc) compiling for the Pi.
Run

Hello ,

I'm trying to setup emerge and kernel compilation to use my x86 OS X machine.

That is the goal. I already test to compile code on OS X a
nd move it to Raspberry and its working.


#### Compile the code on OS X machine:
{12:12}g1r5-hack:~/Desktop@master✗✗✗✗✗✗ vhristev$ /usr/local/linaro/arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc -g -o hello hello.c

#### Move the code to Raspberry Pi 3
{12:14}g1r5-hack:~/Desktop@master✗✗✗✗✗✗ vhristev$ scp hello vhristev@192.168.1.5:~/

#### Test the code on Raspberry
g1r5-berry vhristev # ./hello
Hello World
#### END

I just want to use emerge and kernel compile from Raspberry and my OS X to help out and at some point I can put in the chain my MacBook Pro

After i achieve OS X cross compilation I will try to add my Synology 1515+ .
