Setting up cross compiler (rasp Pi)
-
Hi All,
I'm having few issues setting up the cross compiler for my raspberry pi. I'm a newbie so bear with me on this :)
I'm following the guide on :
https://wiki.qt.io/RaspberryPi_Beginners_Guidein the Compiling qtbase section of this guide once i run the following commands,
- ./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
make -j 4
sudo make install
'/usr/local/qt5pi' folder want there? (do we expect this folder to be there?). On what location i'm meant to run the commands above? i noticed there is a '/usr/local/qt5pi' on /mnt/raspberry-pi-rootfs too may be thats where i'm going wrong.
Could someone kindly help me on this. I've been working on this for a week now.
Any help is appreciated.
Thank you,
- ./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

Hi,
Yes it's a folder as good as any, but with this naming it's clear what it is. It will contain the host tools that will be used to setup/handle your cross-compiled Qt. The one on the remote will contain the cross-compiled libraries that will be used to run your applications.

No, it should be created when you call make install

Got any error message when calling make install ?

@SGaist Hi I'm sorry about the delayed response.
I re-ran the config just to make sure whether there are any errors.I didn’t notice any. I ran config, make, sudo make install all three on ~/Qt/5.5/Src$ and still i cant see /usr/local/qt5pi created?
Not sure what im doing wrong here. My home folder is encrypted (if that makes any diffrence). i thought running sudo make install enable to create folders on root?
I'm really frustrated with this issue, any help is appreciated,
Thank you very much for your help so far.

When calling configure again, did you do it on a clean tree ?

The compiled files will be on the mounted sd card image. You set qt creator to use those files when configuring.
The only downside to this is that you need to mount that image every time you want to cross compile.
I just made a script to mount the img then open qt creator and it gets me back to where I was. -
When you re-call configure you must do it on a clean tree otherwise you might have problems
