Files: * [@../../example/time/jamroot.jam jamroot.jam] * [@../../example/time/hello.cpp hello.cpp] Our `jamroot.jam` specifies the target we build and the `time` declaration to time the target we build: [import jamroot.jam] [jamroot] Building the example yields: [teletype] ``` > cd /example/time > b2 ...found 9 targets... ...updating 6 targets... common.mkdir bin common.mkdir bin/clang-darwin-4.2.1 common.mkdir bin/clang-darwin-4.2.1/debug clang-darwin.compile.c++ bin/clang-darwin-4.2.1/debug/hello.o clang-darwin.link bin/clang-darwin-4.2.1/debug/hello testing.time bin/clang-darwin-4.2.1/debug/hello.time user: [hello] 0.013509 system: [hello] 0.045641 clock: [hello] 0.000000 ...updated 6 targets... ``` [note The actual paths in the `bin` sub-directory will depend on your toolset.] [endsect]
