however, to include tracing features in a deployed application, you must compile your instrumented applications with the trace compiler directive enabled.
for example, the compiler directive for an x86 architecture could have a flag -dcmp_x86 with a directive like -dcmp_pseries for some code specific to linux on pseries servers.
in addition to the listed options, all single-letter compiler directives can be specified on the command line, as described in compiler directive options.
