Valgrind - adb push failed to copy vgdb

Question

I'm trying to install valgrind on my android device, but when i try to execute adb push Inst / i get an error C:\\VmFiles>adb push Inst / push: Inst/data/local/Inst/bin/vgdb -> /data/local/Inst/bin/vgdb failed to copy 'Inst/data/local/Inst/bin/vgdb' to '/data/local/Inst/bin/vgdb': N o such file or directory

Ofc file vgdb exists in this directory

C:\\VmFiles>ls Inst/data/local/Inst/bin callgrind_annotate cg_diff valgrind vgdb callgrind_control cg_merge valgrind-di-server cg_annotate ms_print valgrind-listener

Answer 1

after some observation i found there is no directory Inst/bin in local so first you need to make a directory in /data/local/Inst/bin

and for that you need root access to your device because you cant access /data/ directory without root permissions then do following steps.

first go to directory where vgdb is placed then execute

adb push vgdb /data/local/Inst/bin/

Answer 2

Syntax for adb push :

adb push <PATH_OF_FILE_ON_HOST> <PATH_OF_FILE_ON_DEVICE>`

Since you are trying to push from Inst/data/local/Inst/bin/ path. Use the below command with absolute path.

adb push /full/path/to/Inst/data/local/Inst/bin/ /path/on/device/test_folder/

This should push all (both files and directory) content of the directory Inst/data/local/Inst/bin/ to /path/on/device/test_folder/

Make sure /path/on/device/test_folder/ exist, or run below command before hand.

adb shell mkdir /path/on/device/test_folder/

Use adb shell ls /path/on/device/test_folder/ to list, if your files are transferred to the device.

Also make sure you have permission to write to /path/on/device/test_folder

Note: You will usually have permission to write to /sdcard/ but again will require root permission to assign execute permission ( chmod ) to the transferred binary.
In this case, may need to root the device.
