Thread Subject: No Compilers in my Matlab 7.5 64-bit?

Hello,

I need to compile a .cpp file in my Matlab 7.5.0 Win XP 64-bit but when I type 'mex -setup', it says the following:

Please choose your compiler for building external interface (MEX) files:
 
Would you like mex to locate installed compilers [y]/n? y
 
Select a compiler:
 
[0] None
 
Compiler: 0

I am new to compiling with Matlab. I do not have Visual Studio installed on this computer. Is it necessary to have this installed? Can I download and install the appropriate compiler from a website?

Thanks for any help!

Hi Daniel,
MATLAB typically ships with the lcc compiler, but lcc is not presently
supported for Windows 64 bit machines. So far as I know, there are no
freely available C compilers out there for that platform.

Hello Will,

Thank you for your help. I don't understand why Mathworks would not choose to natively support this feature in XP 64bit.

thanks again!

Uh?

The MathWorks provides lcc for those who do not have a proper compiler. The fact that there's no viable 64-bit version of this is beyond their conntrol. It's also beyond their control that MS have decided to not offer their 64-bit MSVC++ compiler for free.

Their supported compilers are clearly stated. They cost money.

We're you hoping that TMW would write their own C compiler and give it away for free?

Obviously there is a 64-bit version of lcc http://www.q-software-solutions.de/pub/lccwin64.exe (I have not tried myself)

I do not know the reason why it cannot find its way into Matlab distribution.

Did you read the details? It doesn't sound complete, finished or stable. Not something you'd want to redistribute.

"No building of shared libraries" could be an issue for MEX.

One of the compilers supported for MATLAB 7.5 on Win64 is Microsoft
Platform SDK 14, which I believe is downloadable at no cost. The latest
MATLAB 7.8 supports Microsoft Visual C++ 2008 Express Edition which is
also downloadable at no cost.

Mea culpa. Looks like VS 2008 Express can be coerced into playing 64-bit for no cost. It's not obvious from their (M$) site though.

I believe the SDK is needed in order to use VS Express in 64 bits. Both VS Express and SDK are larger than 1Gbytes, so a good internet connection and a lot of persistent is required to make it works.

Visual C++ 2008 Express works with Matlab 2007a (64bit) and above.

All the information you need is here :

http://www.mathworks.com/matlabcentral/fileexchange/22689.

After unzipping the file be sure to read the readme.txt file in the 64-bit subdirectory. This file gives complete instructions on what to download etc.

I used it to compile Tim Davis's Sparse Suite, which should test if your installation is correct.

Derek O'Connor

Derek, the link is broken.

Sorry for the mess. The period at the end of the url is the problem. It should be

Thank you all for your help! It is greatly appreciated.
