Redhat 5.5
gcc version 4.1.2

I have a directory call lib, and in that directory I have all the shared libraries (about 30) that we get from our customer as we use their API. We link with this API.

directory structure:

/usr/CSAPI/lib

However, our customer will update their API so we get new libraries, normally about 3 or 4.

What I have been doing is when I get new libraries. Is to remove the old one and put in another directory. And replace them with the new libaries in the lib directory.

/usr/CSAPI/Old_libs

The new and old will have the same name. i.e.

libcs.so  < old
libcs.so  < new

Is there a better way to manage this? I was thinking of creating a soft line, but as the names are the same, I am not sure that this will work.

Many thanks,

    Symlinks are a very good way to handle this. I would do something slightly differently. I would create a directory structure like:

    /usr/CSAPI/lib_v1
/usr/CSAPI/lib_v2

    and in each of these I would put the actual files. I would then create a separate directory:

    /usr/CSAPI/lib

    which only contains symlinks to the actual files in lib_v1, lib_v2, etc.

    This way lib has the most current version, but if you need, you can use a previous version by simply changing your LD_LIBRARY_PATH.
