I'm trying to build a C mex file. The C file and https://www.mathworks.com/matlabcentral/answers/169852-error-lnk2019-3-unresolved-external-symbols header files are all on the search path. I've been able to build C mex files, following the documents, but I'm not sure what's wrong here. Here's the error message I'm getting:Error using mex Creating library DynamicProgrammingQ2.lib and object DynamicProgrammingQ2.exp DynamicProgrammingQ2.obj : error LNK2019: unresolved external symbol dp_costs referenced in function mexFunction DynamicProgrammingQ2.obj : error LNK2019: unresolved external symbol dp_build_gamma referenced in function mexFunction DynamicProgrammingQ2.obj : error LNK2019: unresolved external symbol dp_all_indexes referenced in function mexFunction DynamicProgrammingQ2.mexw64 : fatal error LNK1120: 3 unresolved externalsPlease point me in the right direction. 2 Comments Show all comments Geoff Hayes Geoff Hayes (view profile) 0 questions 1,998 answers 1,074 accepted answers Reputation: 5,620 on 14 Jan 2015 Direct link to this comment: https://www.mathworks.com/matlabcentral/answers/169852#comment_260486 Matthew - it sounds like your C code is referencing functions, for example dp_build_gamma (and a couple of others too), that you probably have defined in a header but you don't have the body for them. Could it be that there is a library that you should be linking into your build? Also, what is the mex command that you are using to build with?
