s-function link error when build for rtw, dspace ?

I got a third party library and I would like to use it. I made a s-function to use the library, and it was compiled well when I typed mex sfuntest.c my_alg.c threeSpace.lib and I could use in simulink.

But, when I implemented the function in the simulink for rtw and build model for dSpace (xPC, stand alone) I got an link error as shown below.

---------------------------------------------

LINKING APPLICATION ... < lnkppc > (E) #A0368-D Unresolved external: createTSDevice (first referenced in module: my_alg.o04) getFirstAvailableTSSComPort (first referenced in module: my_alg.o04) Errors: 1, Warnings: 0 -- call "C:\PPCTools37\BIN\lnkppc.exe" -QmsA0407 -QmsA0314 -QmeA0307 -QmeA0329 -m..\untitled.map -o ..\untitled.ppc -c _tmp_untitled.lk LINKING FAILED (1)

-------------------------------------------------

I modifed *usr.mk file to inlcude the myal.c and threeSpace.lib. How could I solve this problem?

My one concern is that the library is dynamic library. Can it be a problem? Thank you for your help in advance!

To add custom S-function related build rules for code generation, you need to implement a rtwmakecfg.m file and place it in the same folder as the S-function.

Hi, Thank you for your reply. But, that does not help. I still can generate s-function if I do not want to use it real time workshop. But, once I build model for real time workshop or dpsace, I always see the above error.
