Hello,
I always get an unhandled exception when I'm trying to open las or laz files. I know that the format is 1.4. Is this supported or what could my problem be?

Hi, the support for LAS 1.4 is partial and since the version 2.6.0 or 2.6.1.
If it doesn't work with those versions, can you send me a sample file? (cloudcompare [at] danielgm.net)

Dear Daniel,
I have a problem with Las file importing.
I choosed the option use liblas in CMAKE. An error occured, "error in configuration process, project files maybe invalid"
I read the wiki for liblas, but I am confused. I am using CC 2.6.1 beta on Ubuntu 14.04.
Do I need to install Liblas? from liblas.org ? or CC has the library?
LIBLAS_INCLUDE_DIR
LIBLAS_RELEASE_LIBRARY_FILE
what I must type to these options?
I am using CMAKE gui 2.8.12.2
Could you please help me about this step by step?
Thanks.

You have to compile liblas on your side then tell CMake where the resulting library file and the include directory are.

Hi Daniel,
I have compiled and installed liblas. But I got an error
WARNING: Target "QCC_IO_LIB" requests linking to directory "/usr/local/lib/". Targets may link only to libraries. CMake is dropping the item.
WARNING: Target "CloudCompare" requests linking to directory "/usr/local/lib/". Targets may link only to libraries. CMake is dropping the item.
WARNING: Target "ccViewer" requests linking to directory "/usr/local/lib/". Targets may link only to libraries. CMake is dropping the item.
I think I am showing the folders wrong to CMAKE. Which folders are need to enter there? compiled (builded) files of liblas? or in \usr\local\ lib ?
I am confused.
Thank you.

The LIBLAS_RELEASE_LIBRARY_FILE must point to the actual library file (.a or .so on Linux). When you 'install' liblas, look where it is copied (I guess it is indeed in /usr/local/lib but you must add the right library file at the end of the path.

HI Daniel,
CloudCompare is a great application! I am having a similar problem with an unhandled exception when opening las 1.4 files. I am using V2.6.1 64-bit. The error occurs before the file format dialog. The files can be displayed in lastools so I assume that the format is not a problem. I can provide an example if needed.
