The instrumented application must be executed to produce a coverage results .clog file, used for computing results.

When the tested application is linked with a shared coverage runtime library, the LD_LIBRARY_PATH should be appropriately configured before executing the instrumented application. 

The instrumented application shall be executed according to project-specific setups when collecting code coverage in cross-platform development environments.   

Collecting the .clog file in cross-platform environments may require additional utilities to capture results through TCP/IP sockets, serial links, or a hardware debugger connection.
