Portability of pre-compiled Linux binaries

The basic set of HEASOFT pre-compiled Linux binaries was built under Scientific Linux version 7.4 using its default compilers (GCC 4.8.5), and many of the tasks link dynamically with libgfortran.so.3 (among other libraries). This version of the gfortran library may not be available on all platforms, or, if available, may not include the same set of symbols. This may lead to errors of the following nature when running ftools:

         error while loading shared libraries: libgfortran.so.3:
         cannot open shared object file: No such file or directory


         undefined symbol: _gfortran_internal_malloc
To rectify this problem, we have created patches for our Linux binaries containing the libgfortran that our binaries require.

libgfortran patch for 64-bit Linux (x86_64)

Some users have also found that their C++ library is incompatible as well, noting errors such as this one from xspec:
     libstdc++.so.6: version `GLIBCXX_3.4.5' not found
We have made additional patches to rectify this issue as well:

libstdc++ patch for 64-bit Linux (x86_64)

Unpack the appropriate tar file on top of your existing heasoft-6.25 Linux binary distribution.
