    77When you have built your application and linked it with the BOINC libraries,
    8 you can run it in 'standalone mode' (without a BOINC core client present).
     8you can run it in '''standalone mode''' (without a BOINC client present).
    99To do this, put instances of all input files in the same directory (with the proper logical, not physical, names).
    1010The application should run and produce output files (also with their logical names).
     
    1717
    1818Once your application works in standalone mode,
    19 the next step is to run it under the BOINC client.
     19you can test it under the BOINC client, but without a project server.
    2020This will exercise the various forms of interaction with the client.
    2121If you already have a working project, skip to the next section.

    23 You can test an application under the BOINC client,
    24 but without a project server, as shown in the following example.
    2523This example assumes that your executable name is '''test.exe''',
    2624and that it has an input file with logical name '''in''' and physical name '''input.txt''',

    2927 * Make a directory and put the BOINC client there.  Note: you'll need a 6.10.14 or later client.
    30  * Put the file [http://boinc.berkeley.edu/trac/browser/trunk/boinc/samples/client_state_save.xml samples/client_state_save.xml] in it
    31    (modify this file as needed).
     28 * Put the file

    63 If your app isn't working,
    64 there are two ways to debug it.

    7068the BOINC client will set up the "slot directory" (usually slots/0/)
    7169where your application will run, and then exit.
    72 (Note: a client based on [24143] or later is needed for this).
    7370You can cd into that directory,
    7471check that the needed files are there,
     
    9996It's easier to use BOINC's [http://boinc.berkeley.edu/wiki/Anonymous_platform anonymous platform] mechanism.
    10097To do this:
    101  * Following the [http://boinc.berkeley.edu/wiki/Anonymous_platform directions], create a file 'app_info.xml' in the client's project_* directory, with the appropriate name and version number of your application.
    102  * Each time you build a new version of your application, copy the executable into the project_* directory, making sure it has the appropriate name. Then restart the core client.
     98 * Following the [http://boinc.berkeley.edu/wiki/Anonymous_platform directions],
     99   create a file 'app_info.xml' in the client's project_* directory,
     100   with the appropriate name and version number of your application.
     101 * Each time you build a new version of your application, copy the executable into the project_* directory,
     102   making sure it has the appropriate name.
     103   Then restart the core client.

    130 Once your application is working on your own computers, you're ready to test it with outside computers (alpha testers initially). It may crash on some computers, e.g. because their software or hardware is different from yours. You'll get some information back in the stderr_txt field of the results. If your application called `boinc_init_diagnostics()` with the `BOINC_DIAG_DUMPCALLSTACKENABLED` flag set, and you included symbols, hopefully you'll get symbolic stack traces.

    132138There are separate instructions about [AppDebugWin deciphering a Windows stack trace].

    134 Otherwise, you should at least get numeric (hex) stack traces. There are several techniques for deciphering these. For details see [MacBacktrace Mac Backtrace].  Although that page is written primarily for the Mac, much of it can be used on Linux and UNIX systems as well.
