From: Lizzy on 22 Mar 2010 19:07 Hello everybody, I am trying to install HSPICE toolbox and i am using windows seven. Referring to the setup manual, it mentioned that : Platform Compatibility All files should work across different computer platforms, though the loadsig mexfile may need to be recompiled. It is currently compiled for Sun, Redhat Linux, and Windows 2000/Xp machines. To compile the loadsig function for a different platform, go to the directory containing loadsig.c within Matlab, and then type mex loadsig.c within Matlab. but when I type <mex loadsig.c> in the command window i got this message : ///////////////////////////////////////////////////////////////////////////////////////////// Select a compiler: [0] None Compiler: /////////////////////////////////////////////////////////////////////////////////////////////// and when i enter a <zero>, it gives me : ///////////////////////////////////////////////////////////////////////////////////////////// mex: No compiler selected. No action taken. ************************************************************************** Warning: The MATLAB C and Fortran API has changed to support MATLAB variables with more than 2^32-1 elements.

Hi Lizzy, did you actually run mex -setup? If you run mex -setup, you should be prompted by Matlab to locate compilers. Since you are using Windows, there should be a lcc compiler that ships with Matlab. If you enter >>cd(matlabroot) at the command prompt and then >>cd sys\lcc does that work? in other words do you have at least have a sys\lcc directory in your installation? If running mex -setup doesn't locate any compilers (which is what your output above indicates, but I couldn't understand if you actually ran mex -setup), you'll probably have to contact either your local admin, if you are not the Matlab admin for your installation, or Mathworks technical support directly. It may be a Windows 7 and R2009b issue, not sure. Wayne

The following are supported for release R2009b (which the error message you quoted below suggested you were using) -- scroll down to the 64-bit Windows section to locate an appropriate compiler. http://www.mathworks.com/support/compilers/R2009b/ Don't forget to read the document linked in the footnote. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ
