Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3)

BadBlood

Hello everyone,

I am cross-compiling Qt5 following the instruction from the wiki at https://wiki.qt.io/Raspberry_Pi_Beginners_Guide, but I had some troubles.

I followed all the previous instruction and I had no errors but when i run the command:

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/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 make -j 4 sudo make install

The result was this:

<srcbase> = /opt/qt5/qtbase 
<outbase> = /opt/qt5/qtbase 
Creating qmake...
.Done.
ERROR: Invalid command line parameter 'make'.

Is this result correct? I have Ubuntu 16.04. Thank you in advance

SGaist

Hi,

Looks like you don't have make installed which means that you are missing the basic tools for development.

You should install the build-essential package.

BadBlood

Thank you for your reply, well I have already installed the build-essential package:

michele@michele-SATELLITE-C660:~$ sudo apt-get install build-essential
[sudo] password for michele: 
Lettura elenco dei pacchetti... Fatto
Generazione albero delle dipendenze       
Lettura informazioni sullo stato... Fatto
build-essential è già alla versione più recente. //I have build-essential most recent version
I seguenti pacchetti sono stati installati automaticamente e non sono più richiesti:
  linux-headers-3.19.0-80 linux-headers-3.19.0-80-generic
  linux-image-3.19.0-80-generic linux-image-extra-3.19.0-80-generic
Usare "apt-get autoremove" per rimuoverli.
0 aggiornati, 0 installati, 0 da rimuovere e 1 non aggiornati.

Well, i would like to post all the passages I made to be as clear as possible with problem I had during the passagges to know if I missed something.

First of all, I am working as michele user, in the directory /home/michele/opt as the guide in the wiki says.

1)Downloading files

a)Raspbian
Then I installed Raspbian

wget http://downloads.raspberrypi.org/raspbian_latest -O wheezy-raspbian-latest.zip
unzip wheezy-raspbian-latest.zip

Before mounting it on the new directory /mnt/rasp-bi-rootfs I pay attention to the name and offset of the image. In my case they were:

Name: 2017-04-10-raspbian-jessie.img
Offset: 47185920

So commands were:

sudo mkdir /mnt/rasp-pi-rootfs 
sudo mount -o loop,offset=47185920  2017-04-10-raspbian-jessie.img /mnt/rasp-pi-rootfs

b) Cross-compilator
I downloaded the cross compiling toolchain, but with the commands:

wget https://www.dropbox.com/s/sl919ly0q79m1e6/gcc-4.7-linaro-rpi-gnueabihf.tbz

or

wgethttp://de.sourceforge.jp/projects/sfnet_rfidmonitor/downloads/crosscompilation-resources/gcc-4.7-linaro-rpi-gnueabihf.tbz

What i downloaded was an incomplete .tbz file that i wasn' t able to unzip. I needed to download the file trought the browser at :

http://de.sourceforge.jp/projects/sfnet_rfidmonitor/downloads/crosscompilation-resources/gcc-4.7-linaro-rpi-gnueabihf.tbz

However I moved it in ~/opt (that is, in my case /home/michele/opt)and I unzip it with:

tar -xf gcc-4.7-linaro-rpi-gnueabihf.tbz

c) Libraries
Next i had to install libraries ia32-libs, as I have a 64 bit version (Ubuntu 16.04)
Try installing lib32z1 lib32ncurses5 lib32bz2-1.0 instead. run the commands:

sudo apt-get install lib32z1 
sudo apt-get install lib32ncurses5
sudo apt-get install lib32bz2-1.0

but with the last I had problems, the message was this:

sudo apt-get install lib32bz2-1.0
[sudo] password for michele: 
Lettura elenco dei pacchetti... Fatto
Generazione albero delle dipendenze       
Lettura informazioni sullo stato... Fatto
E: Impossibile trovare il pacchetto lib32bz2-1.0
E: Impossibile trovare alcun pacchetto tramite l'espressione regolare "lib32bz2-1.0"

"Impossible to find the library." I could install only the first ones.(lib32z1 and lib32ncurses)

d) Cross Compiling Tools

I download them with the command:

git clone https://github.com/darius-kim/cross-compile-tools.git

e) Qt5

git clone git://code.qt.io/qt/qt5.git
cd qt5

As I had firewall problems I run:

sed -i 's/git:/https:git./' .gitmodules
./init-repository -f

This command tooe several time.

2) Compiling qt base

First of all I run the command:

cd ~/opt/cross-compile-tools sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc

Then I run the command in directory ~/opt/qt5/qtbase:

/configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/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 make -j 4 sudo make install

It returns the same error than other time. Then I noticed that there was an error in the guide, it isn' t:

make **-j 4** sudo make install

but j and 4 must be near, so it is

make **-j4** sudo make install

Or am I wrong?

However even with this change, the command returned me the same error. Regarding this command I have a a doubt for the parts:

-prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi

the directory /usr/local/qt5pi was in the /home/michele/opt/qt5/qtbase directory. Is it normal? Or does the director refer to the image mounted on /mnt?

Thank you very much, any suggestion would be appreciated.

SGaist

Why such an old version of the compiler ? IIRC, the RPi folks are currently providing the cross-compiler on GitHub.

BadBlood

Could you give me the link, or the name of the version of the cross-compiler? And is there something wrong with what I did?

SGaist

https://github.com/raspberrypi/tools

It's best to use the same generation of compiler that was used for building the distribution.

BadBlood

I did:

git clone https://github.com/raspberrypi/tools

In my ~/opt repository.
but now i don' t know how to exactly use this cross-compiler. Could give me any advice?

SGaist

The same way you use your other cross-compiler.

BadBlood

The problem is that I found 5 different folder that seem to be cross-compiler and I don' t know which to chose:

In the folder /tools/arm-bcm2708 i found these folders:

arm-bcm2708hardfp-linux-gnueabi  gcc-linaro-arm-linux-gnueabihf-raspbian
arm-bcm2708-linux-gnueabi        gcc-linaro-arm-linux-gnueabihf-raspbian-x64
arm-rpi-4.9.3-linux-gnueabihf

which should I use? Moreover Could you tell me even the reason of your choice, because I would like to know in which case i should use other cross compilers. Thank you so much.

PS: I have a raspberry pi3, and I downloaded the 2017-04-10-raspbian-jessie.img image from http://downloads.raspberrypi.org/raspbian_latest

SGaist

I usually select the cross-compiler that matches what was used to build the distribution running on the given device.

In the case of the tools, 4.9.3 is the most recent, the others are several years old and don't make sense to use since you are running the latest image on your device.

Technically 4.9.3 is also not the most recent version of GCC but AFAIK it matches the one used to build the raspbian image.

BadBlood

thank you SGaist, but how could you know the compiler used to build the distribution?

However as now I have the cross-compiler I used the cross-compile-tools I downloaded from the wiki to fix symlinks(what are they?) and lib paths(as the wiki says) . So I command:

cd ~/opt/cross-compile-tools sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc

But i don' think there was some changes, because I tried to modify the path, and I inserted a wrong one, but the command didn' t return any error. Moreover it seemed no time spended to execute the command.

SGaist

Usually looking at the compiler package provided by the distribution provides that info.

The script itself is pretty fast.

Which version of the script did you use exactly ?

BadBlood

I don' t know. The script is called fixQualifiedLibraryPaths and I have only the code, no infos about the version:

#!/bin/bash
#This script is ugly, feel free to fix it

if [ "$#" -ne 1 ]; then
    echo "usage ./cmd target-rootfs"
    exit -1
fi

#passed args
ROOTFS=$1
TOOLCHAIN=arm-linux-gnueabihf

INITIAL_DIR=$PWD

function adjustSymLinks
{
    echo "Adjusting the symlinks in $1 to be relative"
    cd $1
    find . -maxdepth 1 -type l | while read i;
    do qualifies=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | grep ^/lib)
    if [ -n "$qualifies" ]; then
    newPath=$(file $i | sed -e "s/.*\`\(.*\)'/\1/g" | sed -e "s,\`,,g" | sed -e "s,',,g" | sed -e "s,^/lib,$2/lib,g");
    echo $i
    echo $newPath;
    sudo rm $i;
    sudo ln -s $newPath $i;
    fi
    done
    cd $INITIAL_DIR
}

adjustSymLinks $ROOTFS/usr/lib "../.."

echo "Testing for existence of potential debian multi-arch dir: $DEB_MULTI_ARCH_MADNESS"

if [ -n "$DEB_MULTI_ARCH_MADNESS" -a -e "$DEB_MULTI_ARCH_MADNESS" ]; then
    echo "Debian multiarch dir exists, adjusting"
    adjustSymLinks $DEB_MULTI_ARCH_MADNESS "../../.."
fi

Have you a script you are sure that it will work well? I am trying to cross-compile Qt5

SGaist

You should have some feedback. One thing I'd do use the full path rather than ~.

BadBlood

Hi SGaist,

yes I tried to use the full path by command:

./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs /home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc

and what I receiced was this error:

usage ./cmd target-rootfs

Well at that poiint I tried to run this command without the cross compiler path:

./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs

And I received this:

Adjusting the symlinks in /mnt/rasp-pi-rootfs/usr/lib to be relative
Testing for existence of potential debian multi-arch dir:

But I don' t think it is right as I didn' t use any cross compiler in the command, infact when I after run the command to cross compile, it happened:

<srcbase> = /home/michele/opt/qt5/qtbase 
<outbase> = /home/michele/opt/qt5/qtbase

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/mnt/rasp-pi-rootfs/usr/local/qt5pi'.

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

Then i run make -j4 and I receveid this error:

SGaist

Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

@BadBlood The sample commands are wrong. Either you need to && between the individual commands, or run then individually. For example:

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/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 && make -j 4 && sudo make install

OR

> ./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/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
> make -j 4
> sudo make install

Also, maybe try to git from github:

> git clone https://github.com/qt/qtbase.git -b 5.8

Change 2) Compiling qt base:

> cd ~/opt/cross-compile-tools
> sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc

Also, take a look at this bug if you're using raspberrypi/tools:
Update toolchain to support gcc 4.9 raspi3/jessie #73

BadBlood

Thank you very much guys,

I had some problems with cross-compiling and I couldn' t to reply to SGaist. Thank you for && advice, i didn' t know that, and thank you for the link.

I couldn' t reply to SGaist beacuse I wanted to repeat all passages: I had problems with the cross compiling configuration command. In particular when I run the command:

./configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=/home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-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

@SGaist said in Problem cross-compiling Qt5 from Ubuntu to Raspbian(Raspberry pi3):

Your log is not complete, please restart without the -j parameter so you can have the exact point of failure.

Hi SGaist, sorry for delay

The problem was the cross compiler, if I made the configuration with 4.9.3 v. It returned me the error I attached, but if I use the other one(4.7) cross compiling configuration works fine.

However when i run "make" I had the error. As the log is too big to attach here, i will send you the one drive link to the log file containng the error I received.

I can't see any error in the file you shared.
