Top Forums Programming AIX linker oddities...what is going on? Post 302491503 by DreamWarrior on Thursday 27th of January 2011 03:48:31 PM

Speaking of paths...it seems the linker places the path of the shared library in the executable itself. The documentation says to pass -bnoipath to, supposedly, prevent this. However, using -bnoipath (or -Wl,-bnoipath from cc) doesn't seem to work. The path is still present and shown by ldd. This isn't directly an issue because it does appear the runtime linker uses the LD_LIBRARY_PATH first before consulting the paths in the executable, but I'd prefer it not to have the option. This way, if a developer forgets to properly configure the LD_LIBRARY_PATH they don't pick up a version of the library by default, rather they get an error that the library isn't found.

As for the original problem...I still can't make heads or tails of it. We're just going to have to keep fighting the linker. Ugh...

NAME
fastjet-config - fastjet-config DESCRIPTION
This is FastJet configuration tool. Usage: fastjet-config [--help] [--version] [--prefix] [--cxxflags] [--libs] [--shared[=yes|no]] [--plugins[=yes|no]] [--rpath[=yes|no]] [--runpath] [--list-plugins] [--config] The arguments can be either queries (one must be present): --help prints this message and exits --version prints FastJet version and exits --prefix gets the FastJet installation directory --cxxflags returns the compilation flags to be used with C++ programs --libs returns the flags to pass to the linker or flags (optional): --shared controls whether you want to use the static or shared lib (default=yes) --plugins controls whether you also want to link the FastJet plugins (default=no) --rpath adds a -rpath argument at link-time that points to the directory where FastJet libraries are installed. This avoid having to set LD_LIBRARY_PATH at runtime when using shared libs in a non standard location (but may cause the program to inadvertently pick up other shared libraries that happen to be in the FastJet installation directory). (default=yes) --runpath at link-time, adds info about the directory where FastJet libraries are installed to the runpath (ELF systens only). This avoids having to set LD_LIBRARY_PATH at runtime when using shared libs in a non standard location but gives priority to an existing LD_LIBRARY_PATH. --list-plugins list all the available plugins --config shows a summary of how FastJet was configured AUTHOR
