327 | The purpose is two-fold: | |
328 | - search for libraries which will be added to the cache | |
329 | - create symbolic links to the soname for each library | |
330 | ||
331 | This has to be done separatly for each directory. | |
332 | ||
333 | To keep track of which libraries to add to the cache and which | |
334 | links to create, we save a list of all libraries. | |
335 | ||
336 | The algorithm is basically: | |
337 | for all libraries in the directory do | |
338 | get soname of library | |
339 | if soname is already in list | |
340 | if new library is newer, replace entry | |
341 | otherwise ignore this library | |
342 | otherwise add library to list | |
343 | ||
344 | For example, if the two libraries libxy.so.1.1 and libxy.so.1.2 | |
345 | exist and both have the same soname, e.g. libxy.so, a symbolic link | |
346 | is created from libxy.so.1.2 (the newer one) to libxy.so. | |
347 | libxy.so.1.2 and libxy.so are added to the cache - but not | |
