Compile MatrixX Autocode under Linux

Question

Hi, I try to compile my autocoded code under Linux and I got problem at the compilation and at the link.
Everything is working fine under windows....
First Problem. When I switch to linux I got a error at the compilation :
     error: ‘Matrix_Inverse’ was not declared in this scope
Matrix_Inverse is part of sa_matrix.c that was compile before without any problem. Any Idea ? You can find the makefile in attachement.
Second error is during the link. If I put the Matrix_Inverse callout, I able to compile. When it's time to link everything, I got those error:
       TEST_CONTROLPC.o: In function `SCHEDULER':TEST_CONTROLPC.c.text+0x1fb41): undefined reference to `External_Input'
        :TEST_CONTROLPC.c.text+0x1fb91): undefined reference to `External_Output'
        :TEST_CONTROLPC.c.text+0x1fceb): undefined reference to `Error'
        :TEST_CONTROLPC.c.text+0x1fe0f): undefined reference to `Error'
        TEST_CONTROLPC.o: In function `main':TEST_CONTROLPC.c.text+0x218eb): undefined reference to `Implementation_Initialize'
        :TEST_CONTROLPC.c.text+0x218f0): undefined reference to `Background'
        :TEST_CONTROLPC.c.text+0x218fa): undefined reference to `Implementation_Terminate'
        NGC-sa_utils_bin.o: In function `Background()':NGC-sa_utils_bin.c.text+0x313): undefined reference to `SCHEDULER
It's look that it's not able to find function declare in the NGC-sa_utils_bin.c (little adaptation of sa_utils.c). Any idea on that ?
Thanks a lot

Answer 1

All right, let me resume :
We have successfully AutoCode a
MATRIXx model into C code (using default AutoCode template) and compile it on a
windows based computer with our own makefile. On the windows based computer, we
have define –DMSWIN32 in the makefile in order to compile the model.
The result from the AutoCoded
version and the result from the MATRIXx model are the same (diff of
x10-6). Now we want to move the AutocCoded model on a RT-Linux based
computer.
Is
there any other define we should include in the
makefile?
Target computer: RTAI_Linux on
a FEDORA Linux
 And Now to solve the first problem :
        NGC-sa_utils_bin.o: In function
`Background()':NGC-sa_utils_bin.c .text+0x313): undefined
reference to `SCHEDULERTo bypass the problem, we have
made a small modification in order to be able to compile the code. We have
remove the declaration of SCHEDULER() in the procedure Background in the
sa_utils.h and sa_utils.c file.
 sa_utils.c
//extern void SCHEDULER
 sa_utils.h
//EXTERN_FUNC (void SCHEDULER, (
 We have then created the header
file (same name as the model) to declare this SCHEDULER
procedure:
 EXTERN_FUNC (void SCHEDULER, (
 We then run the code and write
outputs in binary to a file. We read them back on a windows based computer to
conclude that the results are not the same of the MATRIXx
model.What do you think ?
