firstly ,i use the laszip.lib in the osgeo4w ,the path is c:\osgeo4w\lib,but the error is the same of the philipp.
sceondly, i delete the laszip.lib  in  c:\osgeo4w\lib,delete laszip.dll in c:\osgeo4w\bin
              and then  i  download the source code of  laszip 2.0.2 and complie it ,and then put the laszip.lib into  
               c:\osgwo4w\lib , laszip.dll to c:\osgeo4w\bin, and update the .hpp in c:\osgeo4w\include
              but the result is the same of the philipp.
can you help me?


philipp 's email is followed:
Hi all,
I want to compile libLAS with Visual Studio 2010 under Windows 7 (x86).
I¡¯ve installed all the necessary dependencies (boost with all Variants,
OSGeo4W with gdal-devel, geotiff, oci, ...) and used the default
Directories to be as synchron as possible with the install-guide.

But I get this error all time:
Error      70           error LNK1120: 1 unresolved externals
C:\dev\libLAS\bin\Debug\liblas.dll         liblas

     C:\dev\libLAS\src\header.cpp.obj          liblas

Any idea ?

Thanks for any help,

philipp
