RPI installing cross-compiling
-
Hello,
I'm working on the installation of qt for cross-compiling.
For the installation I followed tho wiki:
https://wiki.qt.io/RaspberryPi2EGLFS
The Qt-Version is: 5.10.1 for raspberry#zero w
On step 10 I tried to execute the following command:
./configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v
But I got an error
You don't seem to have 'make' or 'gmake' in your PATH.
Cannot proceed.
This is my PC:
Ubuntu 18.04.2 LTS
4.15.0-29-generic x86_64Please could somebody give me a solution?
Thanks in advance. -

make --version
Hi Pablo-J.Rogina;
thanks for your helpful answer,
This command make --version said no make installed.
After I installed make,

I continued with the command
./configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v
and the error
make: g++: Command not found
Makefile:242: recipe for target 'main.o' failed
make: *** [main.o] Error 127
appeared.
I installed g++
Thread model: posix
gcc version 7.3.0 (Ubuntu 7.3.0-27ubuntu1~18.04)
Then I cleaned the everything like suggested on the end of step 10
git clean -dfx
and repeated step 10 again.
When I execute the command again I got the error:
Project ERROR: Cannot run target compiler '/home/kurt/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++'. Output:
sh: 1: /home/kurt/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++: not found
Maybe you forgot to setup the environment?
Now I have no idea what to do. How can I check the setting in environment?
The command
env
shows a correct HOME
The command
ls /home/kurt/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-g++
shows the correct file.Now I have no idea what to do!
Please could somebody give me a hint?Regards

Hello,
thanks to all. The installation is perfect. But....
Now I can't debug.
As I start debugging I get the following error:
The selected build of GDB does not support Python scripting.
It cannot be used in Qt Creator.
I found something that I need to install gdb-multiarch on Ubuntu. s this correct? and where I have to setup the GDB?
Who can give me some help?

could this issue be worth its own post? So not to mix topics? Thanks.
