Building Debian for the A20 under Ubuntu

[dave-at-axon]

Hi all,

I have Android building no problem but now I want to have a go with Linux but I am running into an issue with the compile bit. The system can't find the compiler and the only option for apt-get is a debian source.

Anyone got this to build under Ubuntu and could share how you setup the build system or a link to an online resource?

make: arm-linux-gnueabihf-gcc: Command not found

The following does not work as the source of gcc-4.7-arm-linux-gnueabihf is unknown.

Code Select Expand

apt-get install gcc-4.7-arm-linux-gnueabihf ncurses-dev uboot-mkimage

OK. I found this.

http://askubuntu.com/questions/472219/how-to-install-gcc-4-7-arm-linux-gnueabihf-on-ubuntu-12-04

Now I can install the compiler. Next stage is to see if it will compile

[dave-at-axon]

I've managed to compile the main source but I can't get uboot to compile. I get this error when I try to compile it.

Code Select Expand

Makefile:479: *** "System not configured - see README".  Stop.

using this as the compile command

Code Select Expand

make A20-OLinuXino_MICRO CROSS_COMPILE=arm-linux-gnueabihf-

I followed the instructions from here.

The A20-OLinuXino_MICRO entry I can see in the boards.cfg file.

I've done the usual Google search on the error and get mainly hits on the Makefile

Anyone care to offer any help on what might be wrong? There seems to be a lot less searchable help on Google for Debian Linux building than there is for Android

Are you sure there are capital letters ;-)
Almost everything in linux is case sensitive :-)

I see in the HOWTO and you should check the boards.cfg:

# make a20-olinuxino_micro CROSS_COMPILE=arm-linux-gnueabihf-

I.e NOT A20-OLinuXino_MICRO.

Good Luck

[dave-at-axon]

I tried with both, same result. I used the capitals as that is what is in the boards.cfg file.

Hi Dave,

You need to do "config" first, then compile ...

make A20-OLinuXino_MICRO_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

Hoping this help,

[dave-at-axon]

Cheers for that.

The compilation is now complete.

[scout_3pm]

Well you didn't go to the revision that is mention in the HOWTO:

I.e when running this command:

Code Select Expand


git rev-parse --verify HEAD


If you don't see this revision

8a4621c488f33089d831168bfa5bae210a5684c8

most likely you are using the latest revision from U-boot ;-)

If you were at the revision mention in the HOWTO the command with
lowercase letters is right ;-) I compiled it a few days back and all is fine.

[dave-at-axon]

I get this:

44910e96f4340754484b930f91d837ac1fbea9a0

Anyway, the information from martinayotte sorted it out and I now have both compiled.
