I am creating block scheme i want to use hil sdk functions to controll qube servo 2 from for linux (ubuntu 20.4.)

https://github.com/quanser/hil_sdk_linux_x86_64

These functions should be only c functions.

I created S function but i can't link .a static link library and .h how can it be done ?

Hello Dear,

Have you solved the problem ? I have also same problem. Actualll, I can compile s-function and get output file with .mexwa extension. However , when I run the simulink mod el , Undefined symbol error occured.

When compiling and linking your s-function using the mex command, you can provide optional argument -L to link to a library.

You can also use the legacy_code tool or the C Caller Block to define your s-function and specify the names and locations of libraries that are to be linked with your s-function.

Thank you for your answer but , i don't really understand how it should it work I have c file with code which i want to get to matlab. I have this in makefile:

CFLAGS += -I/opt/quanser/hil_sdk/include

LDFLAGS += -L/opt/quanser/hil_sdk/lib

LIBS += -lhil -lquanser_runtime -lquanser_common -lrt -lpthread -ldl -lm -lc

myhilapp: myhilapp.o

cc $(LDFLAGS) $< -o $@ $(LIBS)

myhilapp.o: myhilapp.c

When i write make in terminal it generates file from .c file and i can run it using ./

How can i convert this makefile to matlab and make it work altogether ?
