Using the MATRIXx linksim cmd with Visual C+ for UserCode

[Starflyer59]

Need help. Trying to create a static library in the Microsoft Visual C+ Developement environment (v6.0) and link it to MATRIXx (v62.2) using the "linksim" Xmath command. I build the library in MS Vis C and then add it to the makeucb.mk file in the ../sysbld/bin/ directory. Next, I use the "linksim" command to build my simucb.dll.

I have not been sucessful trying to make the simucb.dll file by hand using the "nmake -f makeucb.mk" DOS command. I keep running into a "fatal error U1083" where a macro is not defined. I assume that linksim is taking care of this for me.

I'm open to any suggestions. Basically what I am needing is a better way to incorporate large and complex UserCode algorithms into my MATRIXx
models.

You need to define the platform (#define PC 1), which should be done before #include "matsrc.h". You should use the linksim command to link the file, but use MSVC to build the library. If you link outside of MATRIXx then you would need to include the necessary libraries (sysbld\lib\libdllutil.lib for stdwrt).

Also build the library using a c file rather than a cpp file, to avoid name mangling.

Attached is a set of files that can be used as a starting point. The files were created in MSVC 6.0 and MATRIXx 6.3.
It is a MSVC static library project. Add.c was added to the project and it was built into a library (.\debug\mxlib.lib)
Then the path and name of the lib file was added to the makeucb.mk and a UCB c file that calls the function in the library was c
reated. (usr01.c). This file is being called from the UCB in test.dat.
