MATLAB: Unresolved external errors(fmin, fmax,…) while generating s-function from Simulink model using RTW

#sfunction #rtw #embeddedcoder #unresolvedsymbolEmbedded Coder

I am trying to generate an s-function from a Simulink model using RTW Embedded Coder. I got the below error-

Writing library for Subsystem_sf.mexw32

subsystem.obj .text: undefined reference to '_fmaxf'

subsystem.obj .text: undefined reference to '_fminf'

subsystem.obj .text: undefined reference to '_fabsf'

subsystem.obj .text: undefined reference to '_sqrtf'

subsystem.obj .text: undefined reference to '_floorf'_

subsystem.obj .text: undefined reference to '_fmodf'| | _

Any suggestions?

P.S: I am using the LCC MATLAB compiler and also tried compiling with VS 2008 &2010.

Solution: Looks like it was to do with the configuration setting on the model.

Set Configuration Parameters>Real Time workshop>Interface>Target function library as C89/C90(ANSI).

If you are using the Linux library “dlopen”, the call to the “mex” command must include the -ldl flag. This requirement is generally referenced in lines 73 – 81 of the example’s script, “run_rtwdemo_shrlib_app.m”:

% To incorporate the shared library in a larger project, custom compile and
% link commands may need to be created. The following commented lines gives

MATLAB: Connecting PostgreSQL with MATLAb using mex wrapper

I was able to compile the program successfully using the following:

   mex testfunction.c -IC:\MatlabWork\Answers\pgsql\include 
-LC:\MatlabWork\Answers\pgsql\lib -lpq

Are you using a C++ compiler? That might be the issue here?
