Subject: libffm and LD_PRELOAD, a tip
Fro those of you that want the extra speed of libffm and do not want
to recompile large packages (octave for example takes a lot of time to
recompile) setting a LD_PRELOAD environent does the trick.
I use "setenv LD_PRELOAD /usr/local/lib/libffm.so.1" (csh obviously)
if i now do a ldd on a file, libffm gets listed first. I did some tests
and it works fine on my system. To be honest i learned this from the
bladeenc author after I asked him is he could link his (binary-only)
program with the faster libs. Using this trick bladeenc runs about 25%
faster in my box.
