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

[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

I received this error:

@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.

https://1drv.ms/f/s!As3fa8j7GVzZl3jMIGjxQEDF-nuJ

[SGaist]

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

[BadBlood]

Sorry but the files was cutted. Now i have the correct one:

https://1drv.ms/u/s!As3fa8j7GVzZl3pQPdL3ROQsNCpe

[SGaist]

You can try the workaround described here.

[BadBlood]

Hi SGaist,

I had another error but the last disappered, i will link the log file.

https://1drv.ms/u/s!As3fa8j7GVzZl3som_ciawx9hu50

First lines were cutted, but there are the most important about the error.

[SGaist]

I'd still opt for changing to a more recent version of gcc like 4.9

[BadBlood]

I tried to use gcc 4.9, but it returns the error during cross compiling configuration, I linked few weeks ago. The cross compiler I chose is in the directory:

/home/michele/opt/tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin

[BadBlood]

I was able to create a raspbian with Qt5 following the guide at this link:

https://medium.com/@amirmann/how-to-cross-compile-qt-for-raspberry-pi-3-on-linux-ubuntu-for-beginners-75acf2a078c

Next I put the image onto SD card, and there was all files.
But i had problems to find raspberry with the laptop through QT5 running on that, I' m going to open an other topic for that. Thank you.

[TV_man]

If it hasn't already been noticed the path setting script checks the number of parameters passed and is expecting 1 but 2 are being passed. I changed "$#" -ne 1 to "$#" -ne 2 and it ran without the error message.

The second parameter is used in the script so it is needed.

However I now get an error 'Cannot run compiler '/home/sam/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-g++'

(It does exist there)

can you run it manually from a terminal?
