Portability of pre-compiled Linux binaries
The basic set of HEASOFT pre-compiled Linux binaries were built under Scientific Linux versions 5.11 (for the 32-bit binaries) and 7.2 (for the 64-bit binaries) using their default compilers (GCC 4.1.2 for 5.11, and GCC 4.8.5 for 7.2), and many of the tasks link dynamically with - among other libraries - libgfortran.so.1 (on 5.11) and libgfortran.so.3 (on 7.2), which 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.1: cannot open shared object file: No such file or directory or undefined symbol: _gfortran_internal_mallocTo rectify this problem, we have created patches for our Linux binaries containing the libgfortran.so.1 our binaries require.
libgfortran patch for Linux (i686)
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 foundWe have made additional patches to rectify this issue as well:
libstdc++ patch for Linux (i686)
libstdc++ patch for 64-bit Linux (x86_64)
Unpack the appropriate tar file on top of your existing heasoft-6.21 Linux binary distribution.
