cmake and boost library installation problem

hi all,

I am new to linux and C++ programming so I'm posting in hope of some help.

I am trying to install a C++ library using boost and cmake but I keep gettin this error in the terminal:

CMake Error at /usr/share/cmake/Modules/FindBoost.cmake:1199 (message):
Unable to find the requested Boost libraries.

Unable to find the Boost header files. Please set BOOST_ROOT to the root
directory containing Boost or BOOST_INCLUDEDIR to the directory containing
Boost's headers.
Call Stack (most recent call first):
CMakeLists.txt:184 (find_package)

---- your help is appreciated.

Chances are you just need to install boost ( library AND dev package ). How to do that depends on your distribution. Don't try compiling it by hand -- boost is huge enough it would take a very long time, and your distro almost certainly has precompiled versions anyway.

What distribution of linux do you have?

hi friend, thanks for the reply.

I am using Fedora 16.I am following the installation at:
Compilation — liblas.org#using-unix-makefiles-on-linux

(I left out the http in the above address , since I cant post websites as I'm new to this forum).

I am downloaded Boost_1_49_0. I extracted the .tar file.
I tried using : ./configure to install but I get the follwoing from terminal :

bash: ./configure: No such file or directory

---- your advice is appreciated

Like I said, I suggest not building boost from scratch. There's almost certainly a pre-compiled version for your distribution. There's good odds you even have boost already, just not its headers. By downloading the tar, and trying to ./configure, you're trying to build boost from scratch.

In fact, what library are you trying to build? There might be a package for that too.

Building it yourself is a last resort, not a first one.

yum install boost-devel

thanks... yum install boost-devel worked.

I am now running into more problems. The library called "Liblas", which I am trying to install can be found at :

Compilation — liblas.org#using-unix-makefiles-on-linux

(I left out the http in the above address , since I cant post websites as I'm new to this forum).

I am following the steps on this web site. So after running :
$ yum install boost-devel

I ran on terminal :
$ cmake -G "Unix Makefiles"

This work fined. next I ran on :
$ make

Then I went on to :
$ make install

At $ make install , it builds 100% but I am getting an error as follows:

-- Install configuration: "Release"
CMake Error at cmake_install.cmake:36 (FILE):
file cannot create directory: /usr/local/share/liblas/doc. Maybe need
administrative privileges.

make: *** [install] Error 1

--- can you suggest what I should do?

I think I figure out what to do as follows:
$ sudo make install

Now I am trying to read a file called "lasinfo" as:
$ lasinfo ../test/data/TO_core_last_clip.las

But I am getting the following error:

lasinfo: error while loading shared libraries: liblas.so.2.2.0: cannot open shared object file: No such file or directory

---- again, your help is appreciated

You probably installed it under /usr/local/lib. Which isn't a bad thing in of itself -- makes it easy to tell apart from the things which your system was able to install automatically. But the dynamic loader doesn't look in there by default... If so, you'll need to

LD_LIBRARY_PATH="/usr/local/lib" lasinfo

or somesuch.

When I run:

$ LD_LIBRARY_PATH="/usr/local/lib" lasinfo

the ouput is some information about the software library itself:

--------------------------------------------------------------------
    lasinfo (libLAS 1.7.0)
--------------------------------------------------------------------

lasinfo options:
  -h [ --help ]         produce help message
  -i [ --input ] arg    input LAS file
  -v [ --verbose ]      Verbose message output

I am trying to open the file "TO_core_last_clip.las" using:

$  LD_LIBRARY_PATH="/usr/local/lib" lasinfo -i[TO_core_last_clip.las]

But I am getting the message:

Cannot open [TO_core_last_clip.las] for read.  Exiting...

--- can you suggest anything?
thanks

just to update.... I managed to read the file in terminal:

$ LD_LIBRARY_PATH="/usr/local/lib" lasinfo /home/peter/libLAS-1.7.0/test/data/TO_core_last_clip.las

thanks again,
peter
