Re: cross-compiling difficulty with on-the-fly gen/build/use paradigm

I'm having a problem trying to cross-compile audit. The problem

gen_actiontabs_h is built using the cross-compiler (for ARM), and then it's

compiling, but this issue hasn't been brought up, AFAICT]
Is there a simple way around this? A complex way, perhaps? Extra points
for simple!
Unfortunately no. This code has been there for quite a while. The issue is
basically that we were doing performance analysis of ausearch/report and
libauparse. We found that the integer to string lookups were causing a
performance hit. Mirek wrote some code to turn these from a serial search into
a sorted list that I think are now searched using a b-tree algorithm. So, at
compile time what happens is these tables are sorted so that later they are
fast. This improved performance quite a bit.
