Is target-os a property defined by default?

Jürgen Hunold — Mon, 03 Dec 2012 09:09:26 GMT

Yes, <target-os> and also <host-os> are predefined. Using [ os.name ] is wrong in other Jamfiles as well. The patch looks good.

I've added the patch and a trace

    if <target-os>windows in $(properties)
    {
      echo "************************************************************" ;
      echo "windows build."           ;
      echo "************************************************************" ;
      api = win32 ;
    }
    else
    {
      echo "************************************************************" ;
      echo "pthread build."           ;
      echo "************************************************************" ;
    }

and it doesn't works for me on MinGW. It seems the test fails always.

If you need pthread you should specify the paths.
You can specify them in site-config.jam, user-config.jam
or in the environment.
For example:
PTW32_INCLUDE=C:\Program Files\ptw32\Pre-built2\include
PTW32_LIB=C:\Program Files\ptw32\Pre-built2\lib

Do you have any idea what could be wrong?
