[Liblas-devel] VS2010 LNK2005 error between msvcprtd.lib and libboost

[Werner Goeman]

Hello Michael,

Thx for your answer.

The problem seems to be that the choices which boost gives you are a 
bit unclear, compared to the explanation in the documentation.

You need to install the multithread static libs, sais the doc.

In boost you got eight options: the one which make cmake work correctly 
is "multithread debug", that way you have libs which filename start with 
libboost*.lib. The "multithread static (debug)" nor "multithread dll 
(debug)" are doing a good job...

So, an easy solution is indeed: install all possible lib files in the 
lib directory and cmake will select the correct one for you.

Thanks again!
Werner
