→ There is some reference missing with your code.

→ Check your have properly mentioned Include directories and the Library directories  in configuration properties of VC++ Directories

→ Check your Additional Include Directories in the C/C++ General properties

→ Also Check the project configuration is x64  for x64 version of Creo

Have you been able to resolve the error? I'm receiving the same error trying to create a DLL (using a makefile). I do not receive an error when creating an EXE.

Hello WILLIAM TUTTLE‌ If your application works fine with  .exe and not working in dll means you may missed some additional dependencies in you Linker configuration

Check the following static library added with your Additional dependencies

kernel32.lib

user32.lib

gdi32.lib

winspool.lib

comdlg32.lib

advapi32.lib

shell32.lib

ole32.lib

oleaut32.lib

uuid.lib

odbc32.lib

odbccp32.lib

These libraries are windows library file which defaults come with win32 application and we have to add in Make File or Dynamic Library Project

[PARTHIBAN_K]

WILLIAM TUTTLE‌, keerthana guru‌ can you post your Makefile here

[wtuttle]

Parthiban ,

These library files (winspool.lib advapi32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib)  were not in the original make file. I have added them and re-ran the make file – I still receive the error.

Regards,

Bill

Hi WILLIAM TUTTLE‌,

make sure your project configuration is Makefile and Platform(x64).
