| Post subject: | error while loading shared libraries |
Hi all, I successfully installed galprop on SLAC cluster but now when I try to run it I get this one line fatal error: ./galprop: error while loading shared libraries: libcfitsio.so: cannot open shared object file: No such file or directory I tried checking the path to cftio installation I feed it when doing "./configure" and did find the file over there so I'm a clueless. Any help would be greatly appreciated. |

You probably need to set the environment variable LD_LIBRARY_PATH so that it contains the location of libcfitsio.so: export LD_LIBRARY_PATH=/path/to/libcfitsio:$LD_LIBRARY_PATH |

The default shell on SLAC is tsh so the command is setenv LD_LIBRARY_PATH /path/to/libcfitsio:$LD_LIBRARY_PATH |

Normally the ./configure as in the README does this automatically without requiring the setenv, as for the other libraries. Except for clhep which seems to still require it. Evidently it does not always work. |

The configure script only finds the library during compilation. That is only enough for the runtime, if the library is statically compiled. For shared libraries you need to set the LD_LIBRARY_PATH as well unless it was installed in a system library directory. |

So when only static (.a) is available, it is incorporated in the executable. When only runtime (.so) is available, it requires setting the LD_LIBRARY_PATH. When both are available (e.g. CCfits, gsl) , it evidently takes the .a. But I find that for clhep, where both are also available, it takes the .so and requires setting the LD_LIBRARY_PATH. So it is not yet quite clear. Useful info to add to the README. |
