Using the latest version from liblas website (liblas-1.2.1-win32.zip) I'm 
unable to pass the linking phase.
Those are the errors I get in Release mode linking liblas.lib (i have listed 
only the errors for reader10.obj but those are the same for every .obj):

So it seems that the .lib shipped in liblas-1.2.1-win32.zip is unable to link 
against Visual Studio 10.

I have recompiled liblas using nmake with BUILD_DEBUG set to YES first and 
then set to NO.
Then I have linked liblas_d.lib in Debug mode e liblas.lib in Release mode. 
Doing so I can pass the linking phase and generate the exe files.

nmake.opt  must be modified with the following lines for VS10 support

!ELSEIF "$(_NMAKE_VER)" == "10.00.21003.01"
MSVCVER = 10.0

One last thing. The lib names in debug mode are:

LAS_LIB = liblas_d.lib
LAS_DLL = liblas_d1.dll
LAS_LIB_DLL = libl1as_i.lib

Are those names misspelled?

Thank Mateusz for your patience...
