Annotation of embedaddon/expat/bcb5/README.txt, revision 1.1.1.1

1.1       misho       1: 
                      2:                    Using a Borland compiler product
                      3: 
                      4: The files in this directory support using both the free Borland command-line
                      5: compiler tools and the Borland C++ Builder IDE.  The project files have been
                      6: tested with both versions 5 and 6 of the C++ Builder product.
                      7: 
                      8:              Using the free BCC32 command line compiler
                      9: 
                     10: After downloading and installing the free C++ Builder commandline version,
                     11: perform the following steps (assuming it was installed under C:\Borland\BCC55):
                     12: 
                     13: 1) Add "C:\Borland\BCC55\BIN" to your path
                     14: 2) Set the environment variable BCB to "C:\Borland\BCC55".
                     15: 3) edit makefile.mak: enable or comment out the appropriate commands under
                     16:    clean & distclean, depending on whether your OS can use deltree /y or
                     17:    del /s/f/q.
                     18: 
                     19: After that, you should simply cd to the bcb5 directory in your Expat directory
                     20: tree (same structure as CVS) and run "make all" or just "make".
                     21: 
                     22:                                Naming
                     23: 
                     24: The libraries have the base name "libexpat" followed optionally by an "s"
                     25: (static) or a "w" (unicode version), then an underscore and optionally
                     26: "mt" (multi-threaded) and "d" (dynamic RTL).
                     27: 
                     28: To change the name of the library a project file produces, edit the project
                     29: option source (see step 1 under Unicode below) and change the name contained in
                     30: the PROJECT tag. In a make file, change the value assigned to the PROJECT
                     31: variable. Also, the LIBRARY entry in the .def file has to be changed to
                     32: correspond to the new executable name.
                     33: 
                     34: 
                     35:                        Unicode Considerations
                     36: 
                     37: There are no facilities in the BCB 5 GUI to create a unicode-enabled
                     38: application. Fortunately, it is not hard to do by hand.
                     39: 
                     40: 1. The startup .obj system file must be changed to the unicode version.
                     41:    Go to Project|Edit Option Source, and scroll down to the ALLOBJ tag. Change
                     42:    c0x32.obj to c0x32w.obj. Editing this file can be quirky, but usually the
                     43:    following kludge will make the change stick. Close and save the file
                     44:    (CTRL-F4) then open the options dialog (CTRL-Shift-F11), then click OK on
                     45:    the dialog immediately without changing anything in it. If this doesn't work,
                     46:    you will have to close the project completely and edit the .bpr file by hand.
                     47: 
                     48:    If you are using a make file, just change the startup .obj file assigned
                     49:    to the ALLOBJ variable.
                     50: 
                     51: 2. Add the macro define XML_UNICODE_WCHAR_T. In the GUI that goes in the options
                     52:    dialog, Directories/Conditionals tab, in the Conditional define box. In a
                     53:    make file, put it in the USERDEFINES variable.
                     54: 
                     55: 3. Of course, your code has to be written for unicode. As a start, the "main"
                     56:    function is called "wmain". The tchar macros are an interesting way to
                     57:    write code that can easily switch between unicode and utf-8. If these macros
                     58:    are used, then simply adding the conditional define _UNICODE as well as
                     59:    XML_UNICODE_WCHAR_T will bring in the unicode versions of the tchar macros.
                     60:    Otherwise the utf-8 versions are used. xmlwf uses its own versions of the
                     61:    tchar macros which are switched on and off by the XML_UNICODE macro, which
                     62:    itself is set by the XML_UNICODE_WCHAR_T define.
                     63: 
                     64:                               Threading
                     65: 
                     66: The libexpat libraries are all built to link with the multi-threaded dynamic RTL's.
                     67: That means they require CC32xxMT.DLL present on the installation target.
                     68: To create single-threaded libs, do the following:
                     69: 
                     70: 1. The compiler option for multi-threading must be turned off. Following the
                     71:    instructions above to edit the option source, remove the -tWM option from
                     72:    the CFLAG1 tag. In a make file, remove it from the CFLAG1 variable.
                     73: 
                     74: 2. The single threaded RTL must be called. change the RTL in the ALLLIB tag or
                     75:    variable (GUI or makefile repectively) to the version without the "mt" in the
                     76:    name. For example, change cw32mti.lib to cw32i.lib.
                     77: 
                     78:                               Static RTL's
                     79: 
                     80: To build the libs with static RTL's do the following,
                     81: 
                     82: 1. For the static expatlibs, in the Tlib tab on the options dialog, uncheck the
                     83:    "Use dynamic RTL" box. For the dynamic expatlibs, in the Linker tab on the
                     84:    options dialog, uncheck "Use dynamic RTL". If you are using a make file,
                     85:    remove the _RTLDLL assignment to the SYSDEFINES variable, and change the RTL
                     86:    to the version without an "i" in the ALLLIB variable. For example,
                     87:    cw32mti.lib would become cw32mt.lib.
