# Building your own executable programs {#estexecbuilding}
|
||
|
|
|
||
|
|
A simple mechanism is provided for doing all the configuration needed
|
||
|
|
to build a executable program which uses the speech tools library.
|
||
|
|
|
||
|
|
First, make a directory which will hold your program. To make a program called "do_stuff", type
|
||
|
|
|
||
|
|
est_program do_stuff
|
||
|
|
|
||
|
|
if you haven't got the EST bin directory in your path you will have
|
||
|
|
to add the path explicitly, e.g.
|
||
|
|
|
||
|
|
speech_tools/bin/est_program do_stuff
|
||
|
|
|
||
|
|
|
||
|
|
This will create a Makefile and a .cc file called
|
||
|
|
*do_stuff_main.cc*, which will look something like
|
||
|
|
this:
|
||
|
|
|
||
|
|
~~~~~~~~~~~~~~~{.cc}
|
||
|
|
#include "EST.h"
|
||
|
|
#include "EST_types.h"
|
||
|
|
#include "EST_error.h"
|
||
|
|
|
||
|
|
int main(int argc, char *argv[])
|
||
|
|
{
|
||
|
|
EST_StrList files; // the list of input files will go here
|
||
|
|
EST_Option cmd_line; // the parsed list of command line arguments
|
||
|
|
// will go here.
|
||
|
|
|
||
|
|
// This bit parses the command line args and puts them into
|
||
|
|
// files and cmd_line
|
||
|
|
parse_command_line
|
||
|
|
(argc, argv,
|
||
|
|
EST_String("[OPTIONS] [files...]\n")+
|
||
|
|
"Summary; DO SOMETHING\n"+
|
||
|
|
"-o [ofile] Ouptut file\n",
|
||
|
|
files, cmd_line);
|
||
|
|
|
||
|
|
EST_String out_file; // the name of the output file
|
||
|
|
|
||
|
|
// If a output file has been specified using -o, put it in out_file
|
||
|
|
if (cmd_line.present("-o"))
|
||
|
|
out_file = cmd_line.val("-o");
|
||
|
|
else
|
||
|
|
EST_error("No output file specified");
|
||
|
|
|
||
|
|
// declare EST_StrList iterator
|
||
|
|
EST_StrList::Entries fs;
|
||
|
|
|
||
|
|
// iterate through files and do something.
|
||
|
|
for(fs.begin(files); fs; ++fs)
|
||
|
|
{
|
||
|
|
EST_String file = *fs;
|
||
|
|
|
||
|
|
// Process file
|
||
|
|
}
|
||
|
|
|
||
|
|
return 0;
|
||
|
|
}
|
||
|
|
~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
You can now add any C++ code to this, and compile by typing *make*.
|
||
|
|
|
||
|
|
If you want to create a second program in the same directory, type the
|
||
|
|
same again:
|
||
|
|
|
||
|
|
speech_tools/bin/est_program do_more_stuff
|
||
|
|
|
||
|
|
This time, *do_more_stuff_main.cc* will be created and the
|
||
|
|
appropriate build commands added to the extisting Makefile. If you
|
||
|
|
wish to add an extra .cc file to particular program, simply edit the
|
||
|
|
Makefile and add it on the line:
|
||
|
|
|
||
|
|
do_stuff_CXXSRC= do_stuff.cc extra.cc
|
||
|
|
|
||
|
|
|
