Hello,
My configuration is the following:
Matlab R2020b with toolboxes Simulink, Malab coder, Stateflow, Simulink Coder and Embedded Coder.
I have external manual code library that I want to compile. I want to compile it with my own toolchain that is the qnx 6.5 tooclhain to create a mex library that I can use.
But I have followed all tutorials and still can't understand how to use my own toolchain.
The library I want to mex is called "common". If I don't have mingw64 installed and I type this line
mex -v -IC:/QNX650/target/qnx6/usr/include common.c
--> I have the following error:
Error using mex
No supported compiler was found. You can install the freely available MinGW-w64 C/C++ compiler; see Install MinGW-w64 Compiler. For more options, visit
https://www.mathworks.com/support/compilers.
If I have mingw64 and do the same command, it doesn't work because it has a lot of conflicting types between my toolchain QNX and the mingw64 toolchain (see attached file for all errors)
So my question is simple (but maybe the answer is not):
how can I use only my own toolchain to compile my "common" library?
I don't have for qnx a file like intel_tc.m

It sounds like you have some C code that you want to use in MATLAB or Simulink running on a Windows system. If this is correct, then you will need to modify your C code or the .h files included by your C code to remove QNX specific code. You need to use a Windows compiler in order to use the mex function in MALTAB/Simulink running on Windows. A mex function created with QNX toolchain is not usable on a windows computer.
