[section Time Action]
|
|
|
|
This example shows how to use the `testing.time` utility to show time
|
|
information for building a target.
|
|
|
|
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
