I am trying to mex a c file, which uses winsock. I use the following command in MATLAB:
mex -v -L"D:\Software\MATLAB\R2014b\sys\lcc64\lcc64\lib64" -lws2_32 -lkernel32 MyFile.cpp
I keep getting the errors:
MSVCRT.lib(crtdll.obj) : error LNK2019: unresolved external symbol __imp_EncodePointer referenced in function pre_c_init MSVCRT.lib(atonexit.obj) : error LNK2001: unresolved external symbol __imp_EncodePointer MSVCRT.lib(crtdll.obj) : error LNK2019: unresolved external symbol __imp_DecodePointer referenced in function _CRT_INIT MSVCRT.lib(atonexit.obj) : error LNK2001: unresolved external symbol __imp_DecodePointer
As I understand it EncodePointer and DecodePointer are contained in the kernel32.lib file, but even when I link this file with -lkernel32, I still have no luck!

Hello,
Do you want to compile a mex file in 64 bits with a library in 32bits?
I think, this is not possible (I never succeed to do it).
You have to include the same library but in 64bits.
