Installing BOOST

Trash.Main Steps

1. Download from http://www.boost.org and get the latest version.
2. cd ~/lib directory and extract the archive with tar zxvf <packagename>.tar.gz
3. Change into the boost directory and execute pwd to get full path
4. Add this to your .bashrc If you use bash: export BOOSTROOT=<full path from previous step>, or if you use tcsh add this to your .cshrc: setenv BOOSTROOT <full path from previous step>=.

Known Problems

RedHat 7.3

Using redhat 7.3 the kernel headers in /usr/include from glibc-kernheaders package will give errors similar to the following when compiling IPSuite6/IPv6/IPv6Processing subdirectory /home/jmll/src/boost_1_27_0/boost/detail/atomic_count_linux.hpp:44: atomic_dec_ and_test'. In order to solve this problem upgrading to boost version 1.28 or later is the only solution besides using the old (kernel-headers package from redhat 7.2) but this is probably not a good idea as the glibc libraries were not compiled with those headers. The problem with version 1.28 is they have removed operator* from the weak_ptr class as it is not thread safe(neither is get()). Thus you'll get other compilation errors now. To fix just add it to the following file boost_1_28_0/boost/weak_ptr.hpp after the get() function body.

 //Added for compatibility with previous versions and our code.  Yes its unsafe
 //in multithreaded programs too.
 T * operator-> () const // never throws
    {
        T * p = get();
        BOOST_ASSERT(p != 0);
        return p;
    }
