<h1><a name="idBuild"></a>Build instructions</h1>
<h2><a name="idInstWin"></a>Building on win32</h2>
<p>
<strong>muParser</strong> supports various win32 command-line compilers:
<ul>
<li>Mingw</li>
<li>Borland C++</li>
<li>Watcom</li>
<li>Microsoft CL</li>
</ul>
and provides also project files for MSVC6 IDE and the Borland C++ Builder. In order to compile muParser
from makefiles, open an MSDOS prompt and then move to the muParser/build directory and
type:
<p>
<ul>
<li>mingw32-make -fmakefile.gcc for mingw</li>
<li>nmake -fmakefile.vc for msvc</li>
<li>make -fmakefile.bcc for borland</li>
<li>wmake -fmakefile.wat for watcom</li>
</ul>
</p>
All makefiles support the following options:
<pre>
# Set to 1 to build debug version [0,1]
# 0 - Release
# 1 - Debug
DEBUG = 0
# Set to 1 to build shared (DLL) version [0,1]
# 0 - Static
# 1 - DLL
SHARED = 0
# Set to 1 to compile samples [0,1]
SAMPLES = 1
</pre>
The muParser library is created in the 'lib' folder and the sample
binaries are created in samples\example1 or samples\example3.
<table>
<tr>
<td><img src="images/warning.gif"/></td>
<td>samples\example1 can be compiled *only* when building muParser as a STATIC library (SHARED=0).<br/>
samples\example3 can be compiled *only* when building muParser as a SHARED library (SHARED=1).
</td>
</tr>
</table>
</p>
<h2><a name="idInstLinux"></a>Building on BSD/Linux</h2>
<p>
muParser can be installed just extracting the sources somewhere and then, from a terminal, typing:
<pre>
cd [path to muParser]
./configure [--enable-shared=yes/no] [--enable-samples=yes/no]
[--enable-debug=yes/no]
make
[sudo*] make install
</pre>
<small>* = this command must be executed with root permissions and thus
you have to use 'sudo' or just 'su' to gain root access.
Note that installation is not strictly required.</small>
<p>
The "make" step will create the muParser library in 'lib' and the
sample binary in samples/example1. The samples/example2 and
samples/example3 are win32-specific and thus won't be built.
</p>
</p>
<h2><a name="idInstMisc"></a>Other miscellaneous info Unix-specific</h2>
If you don't like to have your muParser folder filled by temporary
files created by GCC, then you can do the following:
<pre>
mkdir mybuild && cd mybuild && ../configure && make
</pre>
to put all object files in the "mybuild" directory. If you want to use
muParser library in your programs, you can use the pkg-config program
(this works only if muParser was installed with 'make install' !).
The commands:
<ul>
<li>pkg-config muparser --cflags</li>
<li>pkg-config muparser --libs</li>
</ul>
will return all useful info you need to build your programs against
muParser !
<h2><a name="idInstInc"></a><a name="idUseSource"></a>Including the source code directly</h2>
<p>
Sometimes including the library sources directly into an application is the easiest
possibility to avoid linker conflicts originating from different versions of the
runtime libraries used by the parser and your project.
In order to use the parser simply include the following files into your project:
<p>
<i>muParser.cpp</i><br/>
<i>muParserBase.cpp</i><br/>
<i>muParserBytecode.cpp</i><br/>
<i>muParserCallback.cpp</i><br/>
<i>muParserError.cpp</i><br/>
<i>muParserTokenReader.cpp</i>
</p>
And make sure the following files can be found in your projects include path:
<p>
<i>muParser.h</i><br/>
<i>muParserBase.h</i><br/>
<i>muParserBytecode.h</i><br/>
<i>muParserCallback.h</i><br/>
<i>muParserDef.h</i><br/>
<i>muParserError.h</i><br/>
<i>muParserFixes.h</i><br/>
<i>muParserStack.h</i><br/>
<i>muParserToken.h</i><br/>
<i>muParserTokenReader.h</i><br/>
</p>
The parser class and all related classes reside in the namespace <code>mu</code> (MathUtils). So make sure to either
add a using
<pre>
using namespace mu;
</pre>
to your files or reference all classes with their complete name.
</p>
<h2>Where to ask for help</h2>
If you find problems with either compilation, installation or usage
of muParser, then you can ask in the muParser forum at:<br/>
<ul>
<li><a href="https://sourceforge.net/forum/forum.php?forum_id=462843">https://sourceforge.net/forum/forum.php?forum_id=462843</a></li>
