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

[Michael P. Gerlek]

I've not built in a while, but you might try the following steps:

  1- download and unpack boost, from the boost website
  2- download *all* the VS10 binaries from http://boost.teeks99.com; move them from the lib32 dir they come in to the <boost>/lib
  3- run my mpg-config.bat script, after changing any paths as needed

-mpg
