Thread: How to fix linker error LNK2019: unresolved external symbol and error LNK2001

I am new to visual studio. I am going to study libxml2 library. So my first example is parsing a xml file. I follow libxml2 official tutorial. Libxml Tutorial I set the additional include directory path suitably. But there are build errors still remaining. my cpp file is in C. Code for Keyword Example
help me.

The output is as follows.

Libxml is a C language library. It probably wasn't originally engineered to be compatible with C++ and its link stage. Fortunately, since libxml is a popular library, you can download a C++ binding. One popular one is libxml++

I can also recommend PugiXML.
