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

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.
