9 years ago Sorry this is shitty code. 50b0ecad714873a58fd8b52b2886cc772b5056f7 fixes the format string issue.
If you're sorting a big index, it will appear to hang while it's sorting (possibly for days or weeks if it's REALLY big). Giving it more memory with -r helps bring more of the sort into RAM and speeds it up a lot. If it hangs on small files that's definitely a problem.
When compiling sortidx.c some warnings are being displayed. The executable hangs, no output is displayed...
