@MihaiJunior said in RaspberryPi2EGLFS:

CROSS_COMPILE=home/mihai

you forgot / in front of home...

[MihaiJunior]

Same result...

[MihaiJunior]

Still unsolved, I'm open to any method that cand solve this

[MihaiJunior]

Update !!!:

I changed the command into:

./configure -release -opengl es2 -device linux-rasp-pi2-g++ -device-option CROSS_COMPILE=/home/mihai/Desktop/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v -no-use-gold-linker

And now I have this result with the following error:

<srcbase> = /home/mihai/Desktop/raspi/qtbase
<bldbase> = /home/mihai/Desktop/raspi/qtbase
<outbase> = /home/mihai/Desktop/raspi/qtbase

@MihaiJunior Is the path to sysroot correct and does it contain the sysroot?
~/raspi/sysroot

[MihaiJunior]

I change it and it work and after few minutes of instalation i got this:

@jsulm @Lifetime-Qt-Champion , any ideas?

[MihaiJunior]

On the instructions found here: https://wiki.qt.io/RaspberryPi2EGLFS , I saw this "You probably also want to add -jn option to make command, where n is a number of cores you like to use for the complication." Could this be the reason? Can someoane tell where to add this -jn and what value for n?

[jsulm]

@MihaiJunior -jn will for sure not solve your issue. What it does is: compile on n CPU cores to speed up compilation. It is a parameter for make.

[MihaiJunior]

@jsulm, and what can solve my issue? Sorry for having so many questions but untill this step I was able to fix everything...

[jsulm]

@MihaiJunior I don't know dlsym is actually par of C lib and should be there. Maybe still something wrong with your sysroot.
