36 1.1 Building From The Command-Line
37 ----------------------------------
39 This is the easiest, preferred and currently supported method. It can
40 be that a subdirectory of the directory where this file resides
41 contains project files for some IDE. If you want to use that, please
42 refer to the readme file within that subdirectory.
44 In order to build from the command-line you need to make sure that
45 your compiler works from the command line. This is not always the
46 case, often the required environment variables are missing. If you are
47 not sure, test if this works first. If it doesn't, you will first have
48 to configure your compiler suite to run from the command-line - please
49 refer to your compiler's documentation regarding that.
51 The first thing you want to do is configure the source. You can have
52 the configuration script do this automatically for you. The
53 configuration script is written in JScript, a Microsoft's
54 implementation of the ECMA scripting language. Almost every Windows
55 machine can execute this through the Windows Scripting Host. If your
56 system lacks the ability to execute JScript for some reason, you must
57 perform the configuration manually and you are on your own with that.
59 The second step is compiling the source and, optionally, installing it
60 to the location of your choosing.
63 1.2 Configuring The Source
64 --------------------------
66 The configuration script accepts numerous options. Some of these
67 affect features which will be available in the compiled software,
68 others affect the way the software is built and installed. To see a
69 full list of options supported by the configuration script, run
71 cscript configure.js help
73 from the win32 subdirectory. The configuration script will present you
74 the options it accepts and give a biref explanation of these. In every
75 case you will have two sets of options. The first set is specific to
76 the software you are building and the second one is specific to the
79 Once you have decided which options suit you, run the script with that
80 options. Here is an example:
82 cscript configure.js compiler=msvc prefix=c:\opt
83 include=c:\opt\include lib=c:\opt\lib debug=yes
85 The previous example will configure the process to use the Microsoft's
86 compiler, install the library in c:\opt, use c:\opt\include and
87 c:\opt\lib as additional search paths for the compiler and the linker
88 and build executables with debug symbols.
90 Note: Please do not use path names which contain spaces. This will
91 fail. Allowing this would require me to put almost everything in the
92 Makefile in quotas and that looks quite ugly with my
93 syntax-highlighting engine. If you absolutely must use spaces in paths
94 send me an email and tell me why. If there are enough of you out there
95 who need this, or if a single one has a very good reason, I will
96 modify the Makefile to allow spaces in paths.
102 After the configuration stage has been completed, you want to build
103 the software. You will have to use the make tool which comes with
104 your compiler. If you, for example, configured the source to build
105 with Microsoft's MSVC compiler, you would use the NMAKE utility. If
106 you configured it to build with GNU C compiler, mingw edition, you
107 would use the GNU make. Assuming you use MSVC, type
109 nmake /f Makefile.msvc
111 and if you use MinGW, you would type
113 make -f Makefile.mingw
115 and if you use Borland's compiler, you would type
117 bmake -f Makefile.bcb
119 in the win32 subdirectory. When the building completes, you will find
120 the executable files in win32\bin.* directory, where * stands for the
121 name of the compiler you have used.
127 You can install the software into the directory you specified to the
128 configure script during the configure stage by typing (with MSVC in
131 nmake /f Makefile.msvc install
133 That would be it, enjoy.
139 2. Compiler Specifics
140 =====================
143 2.1 Microsoft Visual C/C++
144 --------------------------
146 If you use the compiler which comes with Visual Studio .NET, note that
147 it will link to its own C-runtime named msvcr70.dll or msvcr71.dll. This
148 file is not available on any machine which doesn't have Visual Studio
152 2.2 GNU C/C++, Mingw edition
153 ----------------------------
155 When specifying paths to configure.js, please use slashes instead of
156 backslashes for directory separation. Sometimes Mingw needs this. If
157 this is the case, and you specify backslashes, then the compiler will
158 complain about not finding necessary header files.
161 2.2 Borland C++ Builder
162 -----------------------
164 To compile libxml2 with the BCB6 compiler and associated tools, just follow
165 the basic instructions found in this file file. Be sure to specify
166 the "compiler=bcb" option when running the configure script. To compile the
167 library and test programs, just type
171 That should be all that's required. But there are a few other things to note:
173 2.2.1 Building with iconv support
175 If you configure libxml2 to include iconv support, you will obviously need to
176 obtain the iconv library and include files. To get them, just follow the links
177 at http://www.gnu.org/software/libiconv/ - there are pre-compiled Win32
178 versions available, but note that these where built with MSVC. Hence the
179 supplied import library is in COFF format rather than OMF format. You can
180 convert this library by using Borland's COFF2OMF utility, or use IMPLIB to
181 build a new import library from the DLL. Alternatively, it is possible to
182 obtain the iconv source, and build the DLL using the Borland compiler.
184 There is a minor problem with the header files for iconv - they expect a
185 macro named "EILSEQ" in errno.h, but this is not defined in the Borland
186 headers, and its absence can cause problems. To circumvent this problem, I
187 define EILSEQ=2 in Makefile.bcb. The value "2" is the value for ENOFILE (file
188 not found). This should not have any disastrous side effects beyond possibly
189 displaying a misleading error message in certain situations.
191 2.2.2 Compatability problems with MSVC (and probably CYGWIN)
193 A libxml2 DLL generated by BCB is callable from MSVC programs, but there is a
194 minor problem with the names of the symbols exported from the library. The
195 Borland compiler, by default, prepends an underscore character to global
196 identifiers (functions and global variables) when generating object files.
197 Hence the function "xmlAddChild" is added to the DLL with the name
198 "_xmlAddChild". The MSVC compiler does not have this behaviour, and looks for
199 the unadorned name. I currently circumvent this problem by writing a .def file
200 which causes BOTH the adorned and unadorned names to be exported from the DLL.
201 This behaviour may not be supported in the future.
203 An even worse problem is that of generating an import library for the DLL. The
204 Borland-generated DLL is in OMF format. MSVC expects libraries in COFF format,
205 but they don't provide a "OMF2COFF" utility, or even the equivalent of
206 Borland's IMPLIB utility. But it is possible to create an import lib from the
207 .def file, using the command:
210 If you don't have the .def file, it's possible to create one manually. Use
211 DUMPBIN /EXPORTS /OUT:libxml2.tmp libxml2.dll to get a list of the exported
212 names, and edit this into .def file format.
214 A similar problem is likely with Cygwin.
218 We have tested this only with BCB6, Professional Edition, and BCB 5.5 free
