Crosscompile using desktop packages
Hello!
'got a BBB (Beaglbone Black) here; and want to do some crosscompiling.
Because I hate wasting time watching compilers, I'm very happy to see that
Debian Testing (Stretch) has cross-compilers packages available. !
https://packages.debian.org/stretch/gcc-5-arm-linux-gnueabihf
But what are the implications?
### Question 1a)
Does a packaged cross-compiler
https://packages.debian.org/stretch/gcc-5-arm-linux-gnueabihf
generate code that works seamlessly together with the Debian armhf Distro
http://ftp.debian.org/debian/dists/testing/main/binary-armhf/
???
Or are there incompatibility issues regarding ABI, libc, kernel, ...
and other stuff?
If incompatible, then:
* what's the rationale behind having the Debian armhf Distro, or a
cross-compiler package,
and how/when would I use either?
### Question 1b)
Which cross-compiler do I need to use, to work with the Debian armhf
Distro ? Any other dependencies (libc, ...)?
### Question 1c)
How can I use the Debian armhf Distro on an embedded board such as BBB
(Beaglebone Black)?
Is there a howto somewhere?
### Question 2
What's the state of Debian cross-compilers and the Debian armhf Distro?
Because as far as I can see Derek Molloy (**) is recommending using
using package crossbuild-essential-armhf under Jessie,
but for that you need a special repo:
deb http://emdebian.org/tools/debian jessie main
(**) http://exploringbeaglebone.com/chapter7/#CC_Cross-compilation_on_the_BeagleBone_Platform
But as of July 2014, updates to the Emdebian distributions ceased.
### Question 3
Could you recommend a manner of using some cross-tool-chain and distro?
Is Debian cross-compiler and armhf Distro usable? Or is it
work-in-progress, that will become usable in the future?
(PS: I haven't seen clang-x-arm-linux-gnueabihf unfortunately...)
In case Debian things are still in a state of flux, can you recommend
some alternative for the time being?
(Linaro's cross-toolchain?? But will they work with armhf Distro?)
Thanks.
n.
