I'm trying to get and build the latest cmake (because I want to look at tutorial and examples). I have cmake 2.6 already in my path from the Ubuntu Synaptic Package Manager. I can build it and install it ok, Linux still uses the old 2.6. If I do a sudo cmake -version, it finds the latest 2.8. How do I install it right? Maybe I uninstall 2.6 using the Snaptic Package Manager? Below are my steps:

Thanks,
Paul

Downloaded cmake 2.8.1 from http://www.cmake.org/cmake/resources/software.html
./bootstrap; make; make install
The install failed, so did...
sudo make install
It seemed to work, but...
user@ubuntu:~/cmake-2.8.1$ cmake --version
CMake Error: Could not find CMAKE_ROOT !!!
CMake has most likely not been installed correctly.
Modules directory not found in
/usr/local/bin
Segmentation fault
If try as root, it works...
found http://ubuntuforums.org/showthread.p...ght=CMAKE_ROOT
found http://www.linuxquestions.org/questi...s-user-800222/
user@ubuntu:~/cmake-2.8.1$ sudo cmake --version
[sudo] password for user:
cmake version 2.8.1
Tried...
user@ubuntu:~/cmake-2.8.1$ export CMAKE_ROOT=/usr/local/share/cmake-2.8
user@ubuntu:~/cmake-2.8.1$ ls /usr/local/share/cmake-2.8
include Modules Templates
user@ubuntu:~/cmake-2.8.1$ cmake --version
cmake version 2.6-patch 4
This is the version of cmake installed using Ubuntu Synaptic Package Manager.

sudo apt-get remove cmake

>>> You can only have one version installed.
Two different cmake seem to have conflicting issues.

..

Ok. I uninstalled packages cmake and cmake-data using the Synaptic Package Manager that comes with Ubuntu. Now cmake is only available if I use sudo in front of make cmake command, which may not be a problem. I wonder how I get the 2.8.1 under /usr/local/share/cmake-2.8 to be in my path without doing a sudo.

Thanks,
Paul

Below are some notes:
user@ubuntu:~/cmake-2.8.1$ cmake --version
bash: /usr/bin/cmake: No such file or directory
user@ubuntu:~/cmake-2.8.1$ ls /usr/local/share/cmake-2.8
include Modules Templates
user@ubuntu:~/cmake-2.8.1$ sudo cmake --version
[sudo] password for user:
cmake version 2.8.1
user@ubuntu:~/cmake-2.8.1$ export CMAKE_ROOT=/usr/local/share/cmake-2.8
user@ubuntu:~/cmake-2.8.1$ cmake --version
bash: /usr/bin/cmake: No such file or directory
user@ubuntu:~/cmake-2.8.1$ sudo cmake
cmake version 2.8.1
Usage
...

This solved the problem...

./bootstrap --prefix=/usr
make
sudo make install
user@ubuntu:~/cmake-2.8.1$ cmake -version
cmake version 2.8.1

It is generally not a good idea to install things by hand in /usr. Even though you uninstalled the packaged cmake, you may still have problems with files conflicting. In this case it probably better to use --prefix=/usr/local. Then you should just make sure that /usr/local/bin is in your path (prefereably before /usr/bin) and perhaps add /usr/local/lib to your ld.so.conf setup (ie in a file in /etc/ld.so.conf.d/).
