Keep getting error LNK2019: unresolved external symbol

The IDE I use is Visua开发者_StackOverflowl Studio 2010 Professional, and the library I use is ICU4C 4.8.1 for Win32 for MSVC10.

I have rebuilt all the source codes according to the manual for both Debug and Release, and all tests are successfully passed.

Then I do in the way I do with Boost.

I included \include in C/C++ > Additional Include Directories in Proprieties, which seems to be fine.

I also included \lib in Linker > Additional Library Directories.

However, I keep getting error LNK2019: unresolved external symbol.

Source Code:

#include <unicode/uchar.h>

int main () {
    UBool b = u_isprint('c');
    return 0;
}

Error

1>ClCompile:

Apart from setting additional include directories and library directories, you have to actually link to the library. Go to Project Properties -> Linker -> Input and write the name to the .lib in Additional dependencies textbox. HTH
