The StackTrack checkpoint macros are used to specify the location of checkpoints within an application. Before adding checkpoints in a file, an appropriate StackTrack header needs to be included, and the file needs to be "registered" with the StackTrack system. The simplest way to do this is to add these lines

#include <boost/stacktrack/stacktrack.hpp> 
BOOST_STACKTRACK_FILE 

to the source file.

// open track 
sink log( "foo" ); 
BOOST_STACKTRACK_SCOPE(main) 

Here's a quick example:

#include <boost/stacktrack/stacktrack.hpp> 
#include <iostream> 
 
// sets up this source file for StackTrack 
BOOST_STACKTRACK_FILE 
 
// associate (and capture at beginning of each track) property value for this source file 
BOOST_STACKTRACK_FILE_PROPERTY( my_version, 1.1 )  
 
void bar( int x, int y ) { 
    std::cout << "bar x:" << x << " y:" << y << std::endl; 
} 
 
void foo( int z ) { 
    BOOST_STACKTRACK_SCOPE( foo )    
    BOOST_STACKTRACK_VAL_OF( z )     
 
    int x; 
    for( x = 0; x < z; x++ ) { 
        bar( x, 0 ); 
    } 
 
    BOOST_STACKTRACK_STEP( x10 ) 
    for( x = 0; x < z; x++ ) { 
        bar( x, 10 ); 
    } 
} 
 
int main( int argc, char *argv ) { 
 
    // open track 
    sink log( "foo" ); 
 
    // start main track scope for this thread 
    BOOST_STACKTRACK_SCOPE(main) 
 
    foo( 1 ); 
 
    return 0; 
}
