Unable to install cint on Ubuntu 12.04

Question

I am trying to build cint from sources on Ubuntu 12.04. However it complains about libreadline:

~/Desktop/cint-5.18.00 » ./configure      
Guessing architecture to be linuxx8664gcc
Using current CINT core
Please install the package "libreadline or [lib]readline-dev[el]"!

I have libreadline6, libreadline-dev and libreadline6-dev installed. What should I do?

Edit:

Using --readlinelib option below I am able to run configure, make and make install:

But when I try to run it I get:

~/Desktop/cint-5.18.00 » cint
cint: error while loading shared libraries: libCint.so: cannot open shared object file: No such file or directory

Thanks

• Search for shared lib using using:

  locate libreadline.so
  

  Then run configure with --readlinelib option:

  ./configure --readlinelib=/lib/x86_64-linux-gnu/libreadline.so.6 --prefix=/usr/local
  make
  sudo make install
  

• If cint couldn't find the shared lib libCint.so.

  sudo ln /usr/local/lib/libCint.so /usr/lib/libCint.so
  

  or you may add /usr/local/lib to ld load path:

  sudo echo "/usr/local/lib" >> /etc/ld.so.conf.d/usr-local.conf
  sudo ldconfig
  

  But keep in mind this not recommended, Local installed lib's may conflict with Distribution installed libs. So make links instead if you get such problems.

• If it didn't work. There are multiple readline lib versions. see if they work.

  If your OS is 64bit install:

  sudo apt-get install lib64readline6-dev:i386
  

  I have checked it and it does work. Otherwise check the other one of 32bit:

  sudo apt-get install lib32readline6-dev

How to install cint onto a 64 bit Ubuntu 12.10 box. Here is how I did it:

1. Make a new directory /home/el/foo

2. Go into the directory and checkout the latest and greatest:

   svn co http://root.cern.ch/svn/root/branches/v5-34-00-patches/cint cint
   cd cint
   sudo apt-get install libreadline-dev
   ./configure --readlinelib=/lib/x86_64-linux-gnu/libreadline.so.6.2 --prefix=/usr/local
   
   make
   sudo make install
   sudo ln /usr/local/lib/libCint.so /usr/lib/libCint.so
   

3. Then run it:

   el@apollo:~/foo/cint$ cint
