Error while loading shared libraries: Internal Error

[aruna]

Hi i have done it is able to load file,

[jyijyi]

See if it works for unsandboxed app

Sandbox prevent file read?

does it work when unsandboxed? You might see here on how to change the permission for accessing file outside sandbox:

Btw, which line in the lib is making the SMACK error?

does it work when unsandboxed? You might see here on how to change the permission for accessing file outside sandbox:

[aruna]

Followed same sandboxed is false,

tried by setting xattr also

What is the full error log for unsandboxed app

[aruna]

HI jyijyi,

Due to some emergency work i couldnt send the log data, please check the log data below, i have fixed the permission issues, no it is loading

[jyijyi]

do you know why there is a space character just before “libcustom_Arm.so”?

/legato/apps/7618ecbb168bc980d0c4f2cca97a086e/read-only/bin/…/lib/ libcustom_Arm.so: internal error

You also get this space character here:

Error while loading shared libraries: Internal Error

Followed same sandboxed is false, tried by setting xattr also May 12 20:18:58 swi-mdm9x28-wp user.info Legato: INFO | supervisor[876]/supervisor T=main | app.c CreateFileLink() 2183 | Skipping file link ‘/home/root/lib_custom/libcustom_Arm.so’ to ‘/legato/systems/current/appsWriteable/myfirstapp/lib/ libcustom_Arm.so’: Already exists

Normally for this message of “Skipping file link…”, you should not have this space character:

Wp77 gpsApp gives libssl.so.1.1 error

[aruna]

sorry when i tried to make bold it has happened, earlier i made only file name then changed whole line

[jyijyi]

I diff your libcustom_Arm.so and standard library like libssl.so.1.0.2 , it seems to be a bit different to a normal library, not sure if it is related to the internal error when loading the library:

libcustom_Arm.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=7aac04ea29ab20ac8de64e31d9295, with debug_info, not stripped

BTW, here has an example on how to load 3rd party library libsqlite3.so in the application, it should be similar to your situation.
You can see whether it has problem to load the 3rd party libarary.
