Ug secondary development error lnk20 19

Did the subject ask, "What is the reason for the second development error lnk20 19 of ug?" The reasons for the error of lnk20 19 in ug secondary development are: lack of reference library file, wrong name of function or variable, lack of header file and wrong configuration.

1. Missing reference library file: When using UGAPI or other library files, you need to include the corresponding library file in the link options. If these library files are missing, the linking process will fail.

2. Wrong name of function or variable: The linker performs matching according to the name when analyzing the function or variable. If the name of a function or variable is misspelled, misspelled or called incorrectly, it will also lead to an "errorLNK20 19" error.

3. Missing header file: The header file contains declarations of functions and variables. If you don't include the corresponding header file before using functions or variables, the compiler can't know the types of these functions or variables, which leads to link errors.

4. Configuration error: The secondary development of UG has some specific configuration requirements, such as specifying the correct module path and environment variables. If these configurations are wrong, it may also lead to link errors.
