Real Time Workshop build error 1070

I’m trying to build a model using Real Time Workshop, but each time I try to build, the following error message pops up:

Error building Real-Time Workshop target for block diagram 'test_model'. MATLAB error message:
Error using ==> genMakefileAndBuild at 1070
Error(s) encountered while building model "test_model".

I have investigated all of the documentation & Matlab Central posts about this 1070 error, and I’ve implemented all of the fixes suggested in those resources. I’ve also talked with a Mathworks engineer, but they weren’t able to come up with a solution.

What worries me is that, even when I remove any custom components from my Simulink model, and I just have a couple of constant blocks, an Add block, and a scope, I *still* get this same error when I try to build.

I will paste in my next post below the detailed Matlab screen output, before the build attempt fails.

Does anyone have any idea what might be going wrong, that would prevent even a very simple model from successfully building? Thanks for your help.

As promised above, here is the text that appears on my Matlab screen before each build attempt fails:

cl /O2 /c /nologo -DMODEL=das1act_temp1 -DRT -DNUMST=3 -DTID01EQ=1 -DNCSTATES=16 -DMT=1 -DHAVESTDIO -DXPCMSVISUALC -DXPCCALLCONV=__cdecl -DUSE_RTMODEL -DERT_CORE -D_MT -MT /Op ..\sdbio.c

(Note: there is a HUGE set of similar warning messages preceding these 3 messages below)

Has anyone ever experienced the errors above? Any suggestions? Thanks.

I've gotten this error before. Based on the text you posted I can tell you that it is directly related to this:

NMAKE : fatal error U1077: '"c:\program files\microsoft visual studio 8\VC\BIN\cl.EXE"' : return code '0x2'
Stop.

That means that your simulink diagram successfully made it past the code-generation stage, but the compiler was not able to compile the code for some reason. You could try a different compiler by running "mex -setup" and selecting another compiler.

Thanks, Jesse. I will try using a different compiler...
