Need help with DDS compiler v6 C model in Matlab

Using the DDS compiler V6 from Vivado 2015.2, have no problem generating IP, but when I try to compile the C model in Matlab (following the instruction from the programming guide), the following error message shows up:

 

dds_compiler_v6_0_bitacc_mex.obj : error LNK2019: unresolved external symbol xip_dds_v6_0_data_do_signed referenced in function "void __cdecl do_run(enum mex_opcode,int,struct mxArray_tag * * const,int,struct mxArray_tag const * * const)" (?do_run@@YAXW4mex_opcode@@HQEAPEAUmxArray_tag@@HQEAPEBU2@@Z)
dds_compiler_v6_0_bitacc_mex.mexw64 : fatal error LNK1120: 1 unresolved externals

 

Attached is the Vivado generated c model zip file.  The Matlab script that causes the error is "make_dds_compiler_v6_0_mex".

 

 

Please help!

Re: Need help with DDS compiler v6 C model in Matlab

The linker can't find the shared libraries that come with the cmodel. Are you using linux or windows?
