Error while generating DLL

I have around 50 simulink models.For 47 models i was able to generate harness and use the same harness as argument for slbuild command and generate DLL.This is done with the help of the m-script we created and its generic for all model.

But for the 3 models i am uable to generate DLL and i am getting errors as follows:

.### Build procedure for model: 'VcCcCmptCtr_GT_Harness' aborted due to an error.

Error using tlc_new

Error: Errors occurred - aborting

Error in tlc (line 87)

[varargout{:}] = tlc_new(varargin{:});

Error in callTLCService

Error in tlc_c>InvokeTLC (line 1025)

callTLCService(action, tlcCmd, tlcProfilerOn, buildDir, ...

Error in tlc_c (line 562)

InvokeTLC(dispOpts, buildDir, modelName, rtwroot, ...

Error in coder.internal.ModelBuilder/buildProcedure (line 710)

buildResult = tlc_c(h,...

Error in coder.internal.ModelBuilder/make_rtw (line 197)

buildResult = buildProcedure...

Error in coder.internal.ModelCodegenMgr/make_rtw (line 8)

buildResult = obj.make_rtw(varargin);

Please assist.

Thanks

It looks like the final part of the error is missing. That is usually the most informative part. The trace can help track down bugs, but is generally helpful up to the point where you enter internal functions.

This doesn't look the same most Matlab errors do. Since I don't see anything I'm familiar with, I unfortunately cannot help you. the number of people intimately familiar with Simulink is also fairly limited (compared to Matlab in general).

I reckon that you are encountering an error when trying to generate a DLL for some Simulink models. The error message indicates issues with the TLC (Target Language Compiler) process.

In one of my models, I faced a similar issue in the R2017b version. I could not find any workarounds to overcome this.

Updating to MATLAB R2020b or a later version resolved the issue for me.

I recommend trying the same update to see if it resolves your problem as well.
