Using Visual C++ compiler vs. Lcc compiler

Dear All,

I recently set my compilers to the Visual C++ 2008 Express compilers (using mbuild -setup, and mex -setup).

I received warnings saying that if I redistribute my applications, I would have to make sure the Visual Studio run-time libraries are on the computer I am distributing to.

Does this mean that even if I package the MCR with a standalone executable (using the deployment tool), the user would have to install Visual Studio? If I want to prevent this should I simply use the Lcc compiler?

Thanks, Philip

The user doesn't need to install Visual Studio, but needs to get the associated runtime libraries. I believe these are available for free - for example see Microsoft Download Center (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a7b7a05e-6de6-4d3a-a423-37bf0912db84). I think LCC-WIN32 links against crtdll.dll, which is the standard Windows C runtime library.

Thanks for the info! Does this mean I would have to tell the user to download these run-time files? Or is there a way to include the run-time installation in the MCR or executable? I'm using MATLAB 2010a using the deployment project tool.

I suggest not to use the LCC compiler. The functions compiled by MSVC are remarkably faster. As Kaustubha Govind explained, you do not need the MSVC compiler on the client machine, but just the runtime libs. They are freely available and have a size of some MB only.

Thanks! I asked this in my comment above, but is there a way to include the runtime libs in the MCR so the user would not have to download/install anything themselves?
