which folder I need to download and how I can include that in the whole system such that any apps installed on the target can use this binary. I think I need to bundle this binary with other binaries or at least it should be usable by my application loaded on the target. ---

Another alternative is to rebuild the distribution by following the instructions in: [Rebuild Yocto for wp77xx](https://mangoh.discourse.group/t/rebuild-yocto-for-wp77xx/3646) and the enabling in the layer.conf file based on the Yocto development manuals: [https://www.yoctoproject.org/docs/](https://www.yoctoproject.org/docs/). Specifically, you need to build in: meta-openembedded/meta-oe/recipes-extended/p7zip’s bitbake file: p7zip\_16.02.bb. ---

The previous binary downloaded from github is not working. You can try this binary built by me from yocto source.

Thanks, this worked the way you shown it. Now shall I copy it to /bin folder of the target(MangOH Red board) so that it can be used by any application? ---

i think you should copy to /home/root folder. And your application should set to unsandboxed so that you can use that binary. ---

I can’t copy it to /home/root as I am getting error saying root@swi-mdm9x28-wp:~# cp /tmp/7za / cp: can’t create ‘/7za’: Read-only file system. then I tried cp /tmp/7za /home/root/ it copied but when I try to execute it is not working. I tried root@swi-mdm9x28-wp:~# chmod 777 7za root@swi-mdm9x28-wp:~# 7za -sh: 7za: not found. ---

1. you should use “cp /tmp/7za /home/root” 2. for running the 7za, you should type “./7za” ---

Yes, it works now. Actually I am trying to use system(“7za a test.7z test.csv”) in the application, I am neither getting error nor getting the file compressed. The test file I need to compress is bundled into application using .adef file as follows. bundles: { file: { [r] test.csv /read-only/ } } the file is getting visible in /read-only/ folder of my application, but when I checked it by printing to log as follows LE\_INFO(“test.csv exists: %d”, le\_fs\_Exists("/read-only/test.csv")); it is printing as “test.csv exists: 0”. What I am doing wrng here? pls help. ---

You need to use unsandboxed feature in adef in case you want to use system () api ---

ok thanks, but I didn’t get the answer for le\_fs\_exist() query, any help is appreciated. Also regarding the usage is it fine to use system(“7za a test.7z test.csv”)? or I have to use system(“./7za a test.7z test.csv”) ---

I tried with absolute path le\_fs\_Exists("/legato/systems/current/apps/CompressFile/read-only/test.csv") still the same result, file doesn’t exist. BTW both system(“7za a test.7z test.csv”) and system(“./7za a test.7z test.csv”) didn’t work for me, getting “sh: 7za not found” and “sh: ./7za not found”. ---

ok, my system() function seems to be working, but file is neither getting detected (i.e not finding it) nor compressing it, am I doing mistake in bundling the file or providing the wrong path or is their a problem with any permission?
