Invalid object file error during linking when building model

Hello,

I have a model which uses a s-function block. I was able to build the s-function successfully using the s-function builder and generate a s_func_Name.mexw64 file, a s_func_Name.tlc file and the associated c files (s_func_Name.c and s_func_Name_wrapper.c).

When the generated s-function is used in a simulink model to generate a sdf file for a dSpace MicroAutoBox, the following error is obtained when building:

LINKING APPLICATION ... 
< lnkppc > 
(F) #A0357 Invalid object file:  
Errors: 1, Warnings: 0 
-- call "C:\Program Files\dSPACE RCPHIL 2016-B\Compiler\PPCTools\BIN\lnkppc.exe"  -K0 -QmsA0314 -QmsA0407 -QmeA0307 -QmeA0329 -m..\Main_MAB.map -o ..\Main_MAB.ppc -c _tmp_Main_MAB.lk  
LINKING FAILED (1)

The s-function used external source files, headers and libraries, which have all been included in a rtwmakecfg.m file. The part of the rtwmakecfg file containing the necessary external libraries and source files is illustrated below:

   function makeInfo=rtwmakecfg()
  %RTWMAKECFG.m adds include and source directories to rtw make files.
  %  makeInfo=RTWMAKECFG returns a structured array containing
  %  following field:
  %     makeInfo.includePath - cell array containing additional include
  %                            directories. Those directories will be
  %                            expanded into include instructions of Simulink
  %                            Coder generated make files.
  %
  %     makeInfo.sourcePath  - cell array containing additional source
  %                            directories. Those directories will be
  %                            expanded into rules of Simulink Coder generated 
  %                            make files.
  makeInfo.includePath = {'L:\some_folder1', 'L:\some_folder2'};
  makeInfo.sourcePath  = {'L:\current_folder'};
  makeInfo.linkLibsObjs = {fullfile(pwd,'my_ext_lib.lib')};

I am not able to find out as to why the build process says that my library is an invalid object file.

Any help would be greatly appreciated.

I'm not sure which object file is invalid - the mexw64 is used when simulating in MATLAB, while another library file is generated from the S-Function and built into the model when doing code generation.

I recommend contacting DSpace Support for further assistance regarding this issue.

Hi, did you fix this error now ? I have the same problem as you.
