Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler.

Dear Friends

Hi,

I am developing a simulink and I am in the beggining stage of it, while I face the problem of : Unable to locate a C-compiler required by Stateflow and MATLAB Function blocks. Use 'mex -setup' to select a supported C-compiler.

Can any body help me to solve this?

Thanks

Which MATLAB version are you using and which compiler have you already installed?

2013a.

where can I check the compiler version?

https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2013a_SupportedCompilers.pdf lists the supported compilers. Be sure to look in the correct section for 32 bit vs 64 bit, and be sure to note that Stateflow only supports a more limited list of compilers.

You will probably need one of:

• sdk 7.1 (available for free download)
• visual studio 2012 professional
• visual studio 2010 professional
• visual studio 2008 professional

You should start by giving the command than is listed in the error message:

mex -v -setup

I do not vividly understand what you mean. I think you mean that I have to download a compiler like sdk 7.1 and inestall it?

my windoes is 7- 64 bit.

when I try mex -v - setup I have recieved this error:

Error: Microsoft Visual Studio 2010 Professional Edition was not found by mex -setup.

The Microsoft Visual Studio 2010 Professional Edition linker is

required to build Intel C++ MEX-files. Please make sure that

Microsoft Visual Studio 2010 Professional Edition is installed

properly.

The command is

mex -v -setup

You put a space between the - and the setup

You will need to download and install one of the four compilers I listed.

many thanks for your help. the command of mex -v -setup is asking some questions, and none of my answers work correctly. I think I have to go thorough this:

(uninestall C++ 2010)

do you agree?

But I would need to see the output of the setup attempt.
