Howdy, Trying to make an s-function outside of matlab, and the mingw make utility is citing "undefined reference : mxGetPr" in simulink files as an example. So I'm trying to make sure i have all the includes and libs, and options setup for the make to work. After a few hours of research the mbuild script was brought to my attention. Looking at its xml for make file options, it looks like what i need. But long story short i was attempting to use mbuild but the -setup switch keeps failing. Even though a supported compiler is found… by mex!
>> mbuild -setup Error using mbuild (line 164) Unable to complete successfully. No supported compiler or SDK was found. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, visit http://www.mathworks.com/support/compilers/R2017a/.
