Error compiling Faddeeva function

Hello,

Love this program http://www.mathworks.com/matlabcentral/fileexchange/38787. I have it up and running on my mac to simulate voigt broadening. Im trying to add this functionality to a lab computer running win32 matlab 7.12.0 (R2011a), but I cannot successfully compile with mex.

With Lcc-win32 C 2.4.1 in C:\PROGRA~1\MATLAB\R2011a\sys\lcc:
lcc preprocessor error: .\Faddeeva.hh:30 .\Faddeeva_mex.cc:35 Faddeeva_w_mex.cc:3 Could not find include file <complex>

full verbose: http://pastebin.com/YyLYYe8C

With Microsoft Visual C++ 2010 Express in C:\Program Files\Microsoft Visual Studio 10.0:
Faddeeva.cc 
Faddeeva.cc(184) : error C2124: divide or mod by zero 
Faddeeva.cc(822) : error C3861: 'copysign': identifier not found 
C:\PROGRA~1\MATLAB\R2011A\BIN\MEX.PL: Error: Compile of 'Faddeeva.cc' failed.

full verbose: http://pastebin.com/K4LPd9FN

The only instances of complex.h are in a pythonwx folder not related to matlab. I tried re-installing matlab, and net framework, vs etc. Any help would be much appreciated.

update: same error on windows 7 64bit machine with visual C++ 2010

Still cant get it to work...Looks like it might be easier to rewrite my code in python.

.cc files are for C++, but lcc is only a C compiler and cannot handle C++ code.

but visual C++ 2010 should work right? this is the C++ compiler for the current R2012b. So Im assuming its a 2011a problem. Thanks for the info though I will focus on troubleshooting visual C++ 2010.

[Walter Roberson]

Yes, Visual C++ 2010 Express and Visual C++ 2010 Professional are both supported compilers for R2011a.

The problem might be in the source for the function.

Does the Faddeeva.cc source code have a #include of cmath ?

[alan]

sure does line 123: "#include &ltcmath>" . Is there an easy way to debug/test these packages and add them back in?

Sorry, I don't have my MS Windows session handy.
