The testscript provided on this site will read a binary or library and check for mismatching dependencies with respect to 64on32 in largefile-sensitive systems. It will classify each binary and dependency-lib by looking for the symbols from the transitional 64bit-off_t API in the largefile specification. If we see "open" in the list of dynamic symbols then it is "-32-", and if we see "open64" then it is "-64-".
Apart from these simple ones, there exist dualmode libraries called "3264" and those which don't seem to need any of the problematic callbacks which are marked as "-??-" by the testript. From the combinations only three are invalid:
3264>>-32- -64->>-32- and -32->>-64- ...
in other words: dualmode(largefile) libraries having dependencies on non-largefile libraries, largefile libraries and binaries having dependencies on non-largefile libraries, and finally the inverse of non-largefile binaries linking with largefile-libraries.
The script is smart enough to auto-dectect any 3264 that you have just made up - these will have imported the off_t as an 64bit-off_t entity but you do export both simple calls and calls64. That can be tested actually.
A probable result of running the testscript might look like this:
