Hello everybody! my Xcode had an update to version 9.0, since then compiling does not work anymore. Everytime I try to build an S-Function in Simulink it compiles the *.c files, but then announces: "No supported compiler or SDK was found. For options, visit http://www.mathworks.com/support/compilers/R2016b/maci64.html."

When I try to setup the compiler, for example typing in "mex -setup" in the prompt, Matlab answers after a wile:

*>> mex -setup find: 2671: No such file or directory

find: 2674: No such file or directory

find: 2677: No such file or directory

find: 2700: No such file or directory

find: 2703: No such file or directory

find: 2706: No such file or directory

Error using mex

No supported compiler or SDK was found. For options, visit http://www.mathworks.com/support/compilers/R2016b/maci64.html.*

What should I do to fix this? Thank you for your help in advance, ALEX :)

Hi Alex,

I understand that since upgrading to Xcode 9.0, using MATLAB R2016b you are no longer able to detect a support compiler nor install one. The reason is because for MATLAB R2016b, Xcode 9.0 is not one of the supported compilers, as documented below:

(page 6 of 8)

Now, the quickest fix is to perform a free upgrade to R2017b, which supports Xcode 9.0, as documented below:

https://www.mathworks.com/content/dam/mathworks/mathworks-dot-com/support/sysreq/files/SystemRequirements-Release2017a_SupportedCompilers.pdf/SystemRequirements-Release2017b_SupportedCompilers.pdf

(page 6 of 8).

Cheers,

David

Unfortunately, I am using CVX for convex modeling, which is not compatible on 2017a or b. I need to run my program in 2016B. Can I also have 2017b installed. Can I build the mex in 2017B and use it in 2016?
