Hi,

I am new to this group.

I have a basic question.

To run the sample application like calculator, should the device be rooted?

From the documentation Qualcomm/Hexagon_SDK/3.2/docs/calculator_android.html:

adb shell mkdir -p /vendor/bin/
adb push android_Debug/ship/calculator /vendor/bin/
adb shell chmod 777 /vendor/bin/calculator
adb push android_Debug/ship/libcalculator.so /system/lib/

I think without root access,  the files cannot be pushed to /vendor/bin/ or /system/lib.

Sometimes even with the root access those files cannot be pushed.

I tried to specify /data/local/tmp path. but when I run calculator executable I gor below error:

CANNOT LINK EXECUTABLE "/data/local/tmp/calculator": library "libcalculator.so" not found
Aborted (core dumped)
 
Finally I want an yes/no answer for this question:
Is it compulsory to push the files to /vendor/bin/ and /system/lib/ ?

you can push libcalculator.so to any path. but if the path is other than /system/lib you need to set LD_LIBRARY_PATH to that location. 

adb shell LD_LIBRARY_PATH=/data/local/temp /data/calculator 0 1 1000

You'd better root the phone, otherwise the android OS may prevent your running binary according to security policy.

Is it not compulsory to push the files to /vendor/bin/ and /system/lib/,but you should push all the libs needed and set ADSP_LIBRARY_PATH before run the binary.(e.g.adb wait-for-device shell ADSP_LIBRARY_PATH=/data/local/ /data/local/calculator 0 0 100000)
