cross compiling to android and arm

Lineaxe · 3 Mar 2016, 10:21

Well, I do have some notes on the side I could add in as well I suppose. Once I make it to the end I will add in the info , Start a new thread on Cross compiling from Ubuntu 15.10 (wily) to arm 6 (Pi in this case) . I also want to update my notes on the Android and put it all into a separate thread on Creating code on Ubuntu 15 and deploying it to the Android. There were some steps on installing the latest version of Ant & other things that I had done that aren't mentioned in this thread.

Well , I tried a couple of things again last night to see if I could compile Qt to the .img without errors. No luck ,so far... I am installing 5.4 now as it's the one used in the article , it might get rid of any errors that might have to do with the nonexistant qtwebkit.
Time to get my broccoli,tomato,lettuce & Pepper seeds into starter soil. I want them all a few inches tall b4 I put them outside.

Ok , I got as far as make ... the config command worked with Qt 5.4... running make started compiling until it returned the following errors, which I found out were broken links in /mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf/. Not sure what to do , I will try to find out how to fix the broken links . Maybe I missed something along the way. ( The Saga continues...)

Did you check that your mount is working correctly and that you have access to it ?

Lineaxe · wrote on 5 Mar 2016, 09:12

I have checked my mount to make sure that I have access. I just now sudo'd nautilus and set the mount permission to allow complete access to all files & folders for everyone. ran config and make again, Same errors . I am thinking My next move is to find a copy of the older O/S (7.9) that Qt 5.4 was being compiled for as described in the article. It would be nice to have the make work with O/S version 8+ at some point,I guess. Well , I still learned tons to date, so I will just have to backtrack and run through the steps again. :)

Lineaxe · 3 Jul 2016, 04:54

Well my fertilizer and compost is in, my seeds are planted and receiving their first bit of warm light. Anyhow, I tested the steps on an earlier O/S for arm6 (7.2) and it would not compile either , with same errors. So I read (somewhere in the terminal output that was generated from the make command ) about having to remove old files from previous build before reconfiguring the Qt 5.4 source files for build. The command that it seems it needed was:
make clean

--from the original article the make install command came up with the same errors as well.
and I also tried
sudo make clean install
This is the last step needed in the Qt compile phase so if I get the right syntax... I did those last tests a couple of days ago, so I am now back at it for the week again.Who knows what I will discover ...
Another Continent ?

here is the output error from running ** make install** in ubuntu's terminal. ( it seems have found the libz.so when i ran make clean first, just after ./config )

i think before executing /configure & make command you should fix symbolic link and broken library path. i too faced similar problem 2 days ago not exactly the same but similar.

Lineaxe · wrote on 7 Mar 2016, 13:33

Hi , thanks for your reply, How do I go about fixing the symbolic link & library path. I don't know enough about compiling the source for Qt to fix these problems.

Pheonix · 3 Jul 2016, 14:13

hi, you have to clone a cross compile repository it must be mentioned in whatever manual or steps you are following for cross compilation . From that cloned repository you have to run a script for fixing broken links and path.
please post all the errors you face in this cross-compilation battle because i myself have spent almost 10 days in this process and i just wanna know how many errors are possible in this process.

Lineaxe · 3 Aug 2016, 01:00

Nice to know I am not struggling on alone here...Here is the link to the article I have been working from...
http://exploreembedded.tumblr.com/post/115333857238/guide-to-cross-compile-qt-54-for-the-raspberry-pi
I had been trying these steps out with Qt/5.4/Src and Qt/5.6/Src . I tested both Debian 8 and 7 O/S's for arm6 computer. I am using a Ubuntu 15 machine with a 64 bit O/S .
Phoenix you mentioned cloning the cross compile repository . I copy my results of trying out that step described in the online article.
cd ..
sudo git clone git://gitorious.org/cross-compile-tools/cross-compile-tools.git

This responded with the following:

Cloning into 'cross-compile-tools'...
fatal: unable to connect to gitorious.org:
gitorious.org[0: 2a02:c0:1014::1]: errno=Connection timed out
gitorious.org[1: 64.13.172.37]: errno=Connection refused

Looking into the problem a bit further I find the following online at http://blog.gitorious.org
Gitorious.org is dead, long live gitorious.org...
As you may know, Gitorious was acquired by GitLab about a month ago, and we announced that Gitorious.org would be shutting down at the end of May, 2015.

( I locate and d/l a copy of files as a zip from https://github.com/shahriman/cross-compile-tools and put the files from it into the cross-compile directory which I had previously created) but I don't know if it contains the exact files , it does contain the /home/UbuntuUser/rpi/cross-compile-tools/fixQualifiedLibraryPaths file. I later ran the command from the cross-compile-tools folder with no errors. I copy the terminal results.
./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs ~/rpi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc

https://github.com/shahriman/cross-compile-tools.git contains the same content,

so still the same error at /make step?????????

Lineaxe · wrote on 9 Mar 2016, 06:01

After running ./configure ... ,I get the following line found at the bottom of the results after executing it.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.

What should I be cleaning up? that is why I tried make clean since I wasn't sure what it wanted me to do to remove the leftovers? remove leftover ? Maybe these leftovers are causing the problem?

hello @Lineaxe

let's do a slightly different approach clean everything and start fresh.

create a directory in home folder and
:- put jessie image in it
:- download cross compilation tool chain using following command:-
[wget https://www.dropbox.com/s/sl919ly0q79m1e6/gcc-4.7-linaro-rpi-gnueabihf.tbz]

:- Extract it in directory.

:- mount image as you previously did in mnt/rasp-pi-rootfs

:- now clone cross compile tools repository using.
[git clone git://github.com/shahriman/cross-compile-tools.git]

:- now in directory you created in first step you have 1) image, 2) cross-compiling toolchain 3) cross compile tools repository.

:- now if using 64 bit system run following commands :
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
sudo apt-get install lib32stdc++6

now clone qt5 repository
git clone git://code.qt.io/qt/qt5.git
now go to qt 5 folder [cd qt5]

run following
./init-repository

it will take a while depending upon your Ethernet speed ,make sure that this process is successful [the size of repository will be around 3.4 GB]

now go to the directory we created in step 1(lets say you have created pheonix named directory) there you have a cross-compile-tools folder go to it.
eg : command

cd ~/pheonix/cross-compile-tools

then run
sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/pheonix/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc

then go to qt5/qtbase folder and run the configure , and make command you were running previously.

i did the following while cross compiling pi 2 with qt using my ubuntu 14.04 lts desktop system. cant point to single manual available online because what i did was a cocktail of alll :)

Hi , I am trying out your steps Phoenix ... I while I was installing , I got the following error.
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0
E: Couldn't find any package by regex 'lib32bz2-1.0'
I read up on the error and found out this information.
The package (32 bit) you are looking for is libbz2-1.0:i386, its 64 bit version is libbz2-1.0:amd64.
At first enable multi-arch support (if not done already):

sudo dpkg --add-architecture i386

Now run:

sudo apt-get update

You can now install the package by:

sudo apt-get install libbz2-1.0:i386

Later as I went into the qt5/qtbase folder and ran
~/rpi2/qt5/qtbase$ ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$RPI_TOOLCHAIN -sysroot $RPI_SYSROOT -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -skip qtwebkit -v

I changed an export variable to the new toolchain and ran config again from ~/rpi2/qt5/qtbase
export RPI_TOOLCHAIN=~/rpi2/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-

hello @Lineaxe

try this configure command:-

after fixing the symlinks try this configure command

./configure -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=~/rpi2/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

from your above comment i think you you have made rpi2 folder in ur home directory the italic word in above mention command replace it with right folder and make sure it contains what is mentioned in command.

if it works sucessfully
run:-
make -j 4

sudo make install

Hi Pheonix ,
your configure command worked for me
your make -j 4 worked as well for me
and finally the sudu make install worked ...
I think I can continue on with writing the New Jessie O/S onto the chip :)
The quagmire is now reduced to only a mire ...

I have been doing what is nearly the final steps in the article and found a problem.
When I did copy the .img over to the arm computers memory, the .img was corrupt and won't boot up ... says things like superbad sector ...Here is something interesting , the arm O/S usually starts using only 4GB of memory and you need to expand it to use the full amount of memory. The latest O/S already seems to use alot of the 4GB up. We are adding QT creator to the O/S image . I am wondering if It might go over arm O/S's maximum of 4GB on initialization??
