Compile the C-file in MATLAB - matlab

Question

Description
I got a Mathematica Symbolic Toolbox for MATLAB--Version 2.0 here
Then I using the documentation it cotained to compile in MATLAB enviroment
Installation steps:
1)Go to your Mathematica directory and locate the file mathlink.h in
E:\math\Mathematica\5.\AddOns\MathLink\DeveloperKit\Windows\CompilerAdditions\mldev32\include'
and also the file ml32i1m.lib in
E:\math\Mathematica\5.\AddOns\MathLink\DeveloperKit\Windows\CompilerAdditions\mldev32\lib. Copy both files to a predetermined directory (we will refer to this directory as C:\xxx).
2) Copy the content of compressed file math.tar into C:\xxx.
3) Open Matlab command window and execute mex –setup. Choose “Microsoft Visual C/C++ version 6.0 in C:\Program Files\Microsoft Visual Studio”. This tells Matlab that it needs to use a C compiler (as opposed to Fortran compiler). You’ll need Microsoft Visual C/C++ installed. Do not choose the “Lcc C version 2.4 in C:\MATLAB6P1\sys\lcc” option.
4) Open Matlab command window and run mathrun.m. This program will compile the C-file math.c.
The file I got shown as belew:
Then I do step by step
(1) Find the mathlink.h and ml32i1m.lib in the following path
D:\WolframResearch\Mathematica\8.0\SystemFiles\Links\MathLink\DeveloperKit\Windows\CompilerAdditions\mldev32\include
D:\Wolfram Research\Mathematica\8.0\SystemFiles\Links\MathLink\DeveloperKit\Windows\CompilerAdditions\mldev32\lib
(2)Copy the content of compressed file math.zip into C:\XXX
(3) Compile in MATLAB
mex -setup
(4)last setp
addpath C:\XXX
run mathrun.m
I don't know why?
Update
The matlab code in mathrun.m
addpath C:\XXX;
% adds the directory C:\XXX to the list of directories which Matlab "sees" (referred to as paths)
mlpath='C:\XXX' % The directory where mathlink.h is
mllib='C:\XXX\ml32i1m.lib' % The library ml32i1m.lib
% make command
command=sprintf('mex -D__STDC __ -I % s % s % s', mlpath, 'math.c', mllib);
% compile
eval(command)

Answer 1

Seems like the path is not correctly passed to mex, so it cannot find math.c. Comment the original line:
%command=sprintf('mex -D__STDC __ -I % s % s % s', mlpath, 'math.c', mllib);
and add this one instead:
command=sprintf('mex -D__STDC __ -I%s %s %s', mlpath, 'math.c', mllib);
because the mex documentation specifies that there should be no space between the -I switch and the input path. To be really on the safe side, you can even write:
command=sprintf('mex -D__STDC __ -I%s %s %s', mlpath, fullfile(mlpath,'math.c'), mllib);
