General +========== + + +1.1 Building From The Command-Line +---------------------------------- + +This is the easiest, preferred and currently supported method. It can +be that a subdirectory of the directory where this file resides +contains project files for some IDE. If you want to use that, please +refer to the readme file within that subdirectory. + +In order to build from the command-line you need to make sure that +your compiler works from the command line. This is not always the +case, often the required environment variables are missing. If you are +not sure, test if this works first. If it doesn't, you will first have +to configure your compiler suite to run from the command-line - please +refer to your compiler's documentation regarding that. + +The first thing you want to do is configure the source. You can have +the configuration script do this automatically for you. The +configuration script is written in JScript, a Microsoft's +implementation of the ECMA scripting language. Almost every Windows +machine can execute this through the Windows Scripting Host. If your +system lacks the ability to execute JScript for some reason, you must +perform the configuration manually and you are on your own with that. + +The second step is compiling the source and, optionally, installing it +to the location of your choosing. + + +1.2 Configuring The Source +-------------------------- + +The configuration script accepts numerous options. Some of these +affect features which will be available in the compiled software, +others affect the way the software is built and installed. To see a +full list of options supported by the configuration script, run + + cscript configure.js help + +from the win32 subdirectory. The configuration script will present you +the options it accepts and give a biref explanation of these. In every +case you will have two sets of options. The first set is specific to +the software you are building and the second one is specific to the +Windows port. + +Once you have decided which options suit you, run the script with that +options. Here is an example: + + cscript configure.js compiler=msvc prefix=c:\opt + include=c:\opt\include lib=c:\opt\lib debug=yes + +The previous example will configure the process to use the Microsoft's +compiler, install the library in c:\opt, use c:\opt\include and +c:\opt\lib as additional search paths for the compiler and the linker +and build executables with debug symbols. + +Note: Please do not use path names which contain spaces. This will +fail. Allowing this would require me to put almost everything in the +Makefile in quotas and that looks quite ugly with my +syntax-highlighting engine. If you absolutely must use spaces in paths +send me an email and tell me why. If there are enough of you out there +who need this, or if a single one has a very good reason, I will +modify the Makefile to allow spaces in paths. + + +1.3 Compiling +------------- + +After the configuration stage has been completed, you want to build +the software. You will have to use the make tool which comes with +your compiler. If you, for example, configured the source to build +with Microsoft's MSVC compiler, you would use the NMAKE utility. If +you configured it to build with GNU C compiler, mingw edition, you +would use the GNU make. Assuming you use MSVC, type + + nmake /f Makefile.msvc + +and if you use MinGW, you would type + + make -f Makefile.mingw + +and if you use Borland's compiler, you would type + + bmake -f Makefile.bcb + +in the win32 subdirectory. When the building completes, you will find +the executable files in win32\bin.* directory, where * stands for the +name of the compiler you have used. + + +1.4 Installing +-------------- + +You can install the software into the directory you specified to the +configure script during the configure stage by typing (with MSVC in +this example) + + nmake /f Makefile.msvc install + +That would be it, enjoy. + + + + + +2. Compiler Specifics +===================== + + +2.1 Microsoft Visual C/C++ +-------------------------- + +If you use the compiler which comes with Visual Studio .NET, note that +it will link to its own C-runtime named msvcr70.dll or msvcr71.dll. This +file is not available on any machine which doesn't have Visual Studio +.NET installed. + + +2.2 GNU C/C++, Mingw edition +---------------------------- + +When specifying paths to configure.js, please use slashes instead of +backslashes for directory separation. Sometimes Mingw needs this. If +this is the case, and you specify backslashes, then the compiler will +complain about not finding necessary header files. + + +2.2 Borland C++ Builder +----------------------- + +To compile libxml2 with the BCB6 compiler and associated tools, just follow +the basic instructions found in this file file. Be sure to specify +the "compiler=bcb" option when running the configure script. To compile the +library and test programs, just type + + make -fMakefile.bcb + +That should be all that's required. But there are a few other things to note: + +2.2.1 Building with iconv support + +If you configure libxml2 to include iconv support, you will obviously need to +obtain the iconv library and include files. To get them, just follow the links +at http://www.gnu.org/software/libiconv/ - there are pre-compiled Win32 +versions available, but note that these where built with MSVC. Hence the +supplied import library is in COFF format rather than OMF format. You can +convert this library by using Borland's COFF2OMF utility, or use IMPLIB to +build a new import library from the DLL. Alternatively, it is possible to +obtain the iconv source, and build the DLL using the Borland compiler. + +There is a minor problem with the header files for iconv - they expect a +macro named "EILSEQ" in errno.h, but this is not defined in the Borland +headers, and its absence can cause problems. To circumvent this problem, I +define EILSEQ=2 in Makefile.bcb. The value "2" is the value for ENOFILE (file +not found). This should not have any disastrous side effects beyond possibly +displaying a misleading error message in certain situations. + +2.2.2 Compatability problems with MSVC (and probably CYGWIN) + +A libxml2 DLL generated by BCB is callable from MSVC programs, but there is a +minor problem with the names of the symbols exported from the library. The +Borland compiler, by default, prepends an underscore character to global +identifiers (functions and global variables) when generating object files. +Hence the function "xmlAddChild" is added to the DLL with the name +"_xmlAddChild". The MSVC compiler does not have this behaviour, and looks for +the unadorned name. I currently circumvent this problem by writing a .def file +which causes BOTH the adorned and unadorned names to be exported from the DLL. +This behaviour may not be supported in the future. + +An even worse problem is that of generating an import library for the DLL. The +Borland-generated DLL is in OMF format. MSVC expects libraries in COFF format, +but they don't provide a "OMF2COFF" utility, or even the equivalent of +Borland's IMPLIB utility. But it is possible to create an import lib from the +.def file, using the command: + LIB /DEF:libxml2.def + +If you don't have the .def file, it's possible to create one manually. Use +DUMPBIN /EXPORTS /OUT:libxml2.tmp libxml2.dll to get a list of the exported +names, and edit this into .def file format. + +A similar problem is likely with Cygwin. + +2.2.3 Other caveats + +We have tested this only with BCB6, Professional Edition, and BCB 5.5 free +command-line tools. + + + +Authors: Igor Zlatkovic + Eric Zurcher + + -- cgit v1.2.3
