Hi folks. First off, thanks for the great, freely redistributable tool.
Anyway, I'm writing about the possibility of getting libtool working better on AIX. The primary reason AIX is an exception to the general rules, is that it appears that when you compile an AIX binary defining a library path for the executable at runtime, the first file/directory listed in that path has a special meaning - sometimes. More specifically, if that first directory component really is a directory, then it'll be searched as one would expect on just about any other *ix. However, if that first directory component in the : separated list isn't a directory, then it's interpreted as a "loader domain", which is more or less a namespace for libraries. Why does AIX need library namespaces? Because AIX's default behavior is to load one version, and one version only, of a given library. Yes, if you want libfoo-2.0 and libfoo-1.0 loaded into core concurrently, then tuff nuggies, you only get the first one that was loaded, unless: 1) You slibclean away the library 2) You put one or both of those programs into non-default loader domains So to recap, AIX really wants to place a special interpretation on the first directory in a runtime library load path, sometimes. It appears that libtool, however, sometimes likes to insert directory paths ahead of the directory paths that are specified by the programmer (true?). So if libtool could have some sort of way of specifying something like one fo the following, that might really help matters on AIX: 1) Preserve library search path, taking new dirs on the end 2) Optionally specify a special path that will Always end up first in the library search path 3) Have a general way of specifying what must go ahead of what Any thoughts on how to go about this?
