Is your command working in console with absolute path?
in my side, I don’t see problem to put this in my legato application:
system("/home/root/7za a /tmp/test.7z /legato/systems/current/apps/hello6/read-only/usr/share/sounds/0-to-9.wav\n");
I can see /tmp/test.7z
yes it works with absolute path, may be I am trying to create a .7z file in a read-only folder!! Also why le_fs_Exists("/legato/systems/current/apps/CompressFile/read-only/test.csv") is not showing that the file exists? will it show only files created using le_fs interface?
maybe you can try to create one by API and see where it is located.
I tried copying the test.csv in /tmp/ folder and tried calling system(/home/root/7za a /tmp/test.7z /tmp/test.csv"), file is getting compressed but my application getting aborted and getting following error.
