RaspberryPi2EGLFS cross compile step 10 got error - Project ERROR: Could not determine target architecture

edwardy84

hi there. i m still working on the cross compilation based on the steps here https://wiki.qt.io/RaspberryPi2EGLFS

my host PC is Linux Debian 9.12, my Pi is Raspberry Pi 3 B+

at step 10 after i completed these three commands below:

git clone git://code.qt.io/qt/qtbase.git -b 5.9

cd qtbase

./configure -release -opengl es2 -device linux-rasp-pi3-vc4-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -no-use-gold-linker -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v

it seems working fine after the third command, but i still got the errors below at the last section:

i noticed the few fatal errors in the log:

> main.cpp:2:20: fatal error: alloca.h: No such file or directory

> main.cpp:2:20: fatal error: malloc.h: No such file or directory

> main.cpp:2:20: fatal error: stdlib.h: No such file or directory

> arch.cpp:43:19: fatal error: stdio.h: No such file or directory

any idea how to fix these errors? did i miss out something?

jsulm

@edwardy84 Does you sysroot contain all these header files?

edwardy84

@jsulm may i know how to verify this?

i think these 4 header files are available at the sysroot/includes

jsulm

@edwardy84 Your sysroot does not look right. It should actually have same layout as the filesystem of your device, like:

/raspi/sysroot/
              |
              - usr/
                   |
                   - include/
...

How did you create your sysroot?

edwardy84

@jsulm i created the sysroot based on the step no 8 here https://wiki.qt.io/RaspberryPi2EGLFS

mkdir sysroot sysroot/usr sysroot/opt
rsync -avz pi@raspberrypi.local:/lib sysroot
rsync -avz pi@raspberrypi.local:/usr/include sysroot/usr
rsync -avz pi@raspberrypi.local:/usr/lib sysroot/usr
rsync -avz pi@raspberrypi.local:/opt/vc sysroot/opt

the sysroot/usr does exist, it contains lib folder.

is it something wrong and how should i fix it?

jsulm

@edwardy84 said in RaspberryPi2EGLFS cross compile step 10 got error - Project ERROR: Could not determine target architecture:

is it something wrong and how should i fix it?

As I said this path is wrong: ~/raspi/sysroot/include
It should be ~/raspi/sysroot/usr/include

edwardy84

@jsulm thanks for your catch. i have fixed this problem. and then i can run make and make install command then.

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/home/debian9/raspi/qt5pi'.

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