hello, I have a problem when I want to generate code from Matlab/Simulink with real time workshop for a model: That is what Matlab says to me: ### Starting Real-Time Workshop build procedure for model: test ### Generating code into build directory: .\test_c167_rtw ### Invoking Target Language Compiler on test.rtw tlc -r .\test_c167_rtw\test.rtw 'D:\Matlab6p1\toolbox\c167\bin\c167.tlc' -O.\test_c167_rtw '-ID:\Matlab6p1\toolbox\c167\bin' '-ID:\Matlab6p1\rtw\c\tlc' -aCycTI_pin="P3^2" -aEnforceIntegerDowncast=1 -aExtMode=1 -aFoldNonRolledExpr=1 -aForceParamTrailComments=0 -aGenerateComments=1 -aIncHierarchyInIds=0 -aInlineInvariantSignals=0 -aInlineParameters=0 -aLocalBlockOutputs=1 -aMem_Mod="Huge" -aRTWVerbose=1 -aRollThreshold=5 -aSerTI_pin="P3^3" -aShowEliminatedStatements=1 -aTiming_signals=0 -abaudrate=57600 -aport="COM1" -aReleaseVersion=12.1 -p10000 ### Loading TMW TLC function libraries .. ### Initial pass through model to cache user defined code ### Caching model source code .. ### Creating (RealTime) source file test.c . ### Creating model header file test.h ### Creating model header file test_export.h ### Creating parameter file test_prm.h ### Creating registration file test_reg.h ### Creating data type transition file test_dt.c ### TLC code generation complete. ### Creating project marker file: rtw_proj.tmw ### Creating test.mk from D:\Matlab6p1\toolbox\c167\bin\c167.tmf ### Building test: D:\Matlab6p1\toolbox\c167\bin\gmake.exe -f test.mk Creating link file D:\Matlab6p1\toolbox\c167\work\test_c167_rtw\link.lin D:\Matlab6p1\toolbox\c167\bin\gmake.exe: *** [before] Error 2012694356 When I try to build the target with Keil(C166) with the files created by matlab, These errors appears to me: Simstruc.h(323): error 320: must define one of RT, NRT, MATLAB_MEX_FILE Can you tell me were I'm wrong Thank you and excuse me for my very bad english langage
