I am trying to install the software gpsim. I have successfully (I think) configured, created the makefile and made the files necessary but now when I try and launch the application I get the error:
gpsim: error while loading shared libraries: libgpsim.so.0: cannot open shared object file: No such file or directory
I have established by use of the command:
locate libgpsim.so.0
(maybe sudo locate libgpsim.so.0
that this is present in the /usr/local/lib/ folder but not in the /usr/lib which it needs to be. To correct this a symbolic link can be used (to link the location the application is looking for with the actual file). To do this I have used the command:
ln -s /usr/local/lib/libgpsim.so.0 /usr/lib/libgpsim.so.0
(ln -s <file_location> <new_link_location>)

Now when I try and launch gpsim I there is the same issue with the file libgpsimcli.so.0 so I have done the same as above and now an issue with libgpsimgui.so.0

So, finally onto my question(s)
1). Have I unpacked/created this library in the wrong area i.e. not as root - is this why it is in the /usr/local/lib directory rather than /usr/lib/?
2). Is there a way of doing a bulk symbolic link or batch symbolic link so I can link all the libgpsim* library files in one go?

Apologies for the long post but I wanted to go through my steps in case anyone else has this issue rather than start half way through and skip the how to create a symbolic link.

Many thanks,
Mark

When you build a package from source (one that uses configure in the package source directory), the default behavior is to install in the /usr/local tree -- and this is a "good thing" because anything you install as an "extra" does not interfere with system software. You can, by using arguments to configure, install the package in /bin, /usr/bin, /usr/lib and so on, but it's usually a better idea to install in /usr/local (and there will be some arguments about this). The downside of this is that you may need to add path information to your system so it looks in /usr/local for libraries, executables and the like.

You can add /usr/local/lib to the LD_LIBRARY_PATH environment variable; system-wide, edit /etc/profile and, down toward the end of that file put
You must log out an log back in for this to take effect; /etc/profile is read once at log in.

If you prefer to have user-by-user, edit the .profile (Bourne, BASH or Korn shell), .bashrc (BASH) or .chsrc (C-shell) adding the above using the syntax appropriate for that shell; the example shown is for Bourne, BASH or Korn shells but not C-shell.

You should log out and log back in for the addition to take effect.

Consider, as a general rule, that you install additional software in the default /usr/local tree and that you install "package" software (such as OpenOffice.org) in /opt. Doing this keeps system software and add-on software segregated; you may need to add path information to your /etc/profile (or some other file; check your system documentation).

Hope this helps some.

Hi tronayne

Thanks for your help. I've added the library path to the bash shell and the application gpsim is launching correctly.

Having looked at the contents of /usr/local/lib it would have quite time consuming had I continued down the path of creating symbolic links for all the library files.

Thanks again,
Mark

You can add /usr/local/lib to /etc/ld.so.conf and then run "sudo /sbin/ldconfig". This will add libraries in /usr/local/lib to the list that `ld' searches.

...and that's the other way that I forgot to mention.

Hello!

I had the same problem with gpsim-0.23, and the first solution described by tronayne work perfect. I decided to edit my .bashrc (in suse 11.1), and now my gpsim works without problems.

Thanks a lot.
