Irrnet lite lnk2019 error

[ekuznets]

I am trying to install library for irr net lit but when I link library and include the folder, I got multiple of this errors "error LNK2019: unresolved external symbol".
How this should be fixed?

Thanks for helping.

Welcome to the forum.

When you ask for help please always post the complete error, never ever throw away part of the message (like in this case the information _which_ symbol this is about). Errors are already minimal, if you don't post them completely then you only make it harder for other people to help you.

Linking a library is not the same as including the header. Headers and include path troubles are about compiling, once you get linker errors like here, then the compiling is already done. It mean it's missing the implementation (not the header, it found that). In the case of a library it generally means you have to add the .lib file (or .a file on Unix) to the linker. Which IDE are you using?

Ok so,

This is full log of error as you asked.
Sorry I new to all this(programming also), I am using visual studio express 2010 on Win 7

I'm not really familiar with irrnet lite, but on first view this looks like you might compile the lib and your application with different standard library settings.

Ok then, How to make it properly work?

[thanhle]

It's a link error. You should try search on google on how to fix it. They will show you how to do it.

Goodluck learning,

Sorry, I'm not on Windows currently so can't check the exact option in VS. It's some option where you can chose between stuff like multithreaded debug dll. The option is probably named something like standard library settings or system library, or c-lib settings, don't really know right now without having it in front of me. I don't know the option you need exactly here (depends on your project and that lib, both of which I don't know anything about). If you have the project file of the lib then compare what it does use and use the same.

I believe CuteAlien is right.

"For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'."

From: http://stackoverflow.com/questions/3739 ... press-2005

Try both options 'multithreaded' and 'multithreaded dll', I forgot which one should work.
