* Anyone know how to compile with profiling when using libtool?

Though I can augment CFLAGS so that each .c file is compiled with -g
-pg, I haven't figured out a way to keep libtool from removing -pg
from the link line.  It seems like libtool is removing -pg (and
-no-undefined, etc.) from the gcc command line just before issuing the
link command.

If at all possible, I'd rather not have it second guess me for at
least some of the options...

One workaround is to make a script "my-gcc-pg" which just execs gcc
-pg, and use that by configuring with CC=my-gcc-pg.  I think libtool
recognises gcc based on preprocessor defines, so the name of the
script hopefully doesn't matter.

To do it directly with libtool you can insinuate -Wc,-pg into the
flags, by overriding LDFLAGS or guile_LDFLAGS or whatever.

Rumour has it the next libtool will leave alone anything it doesn't
recognise.


Incidentally, http://sourceforge.net/projects/fnccheck is quite a nice
profiler, based on gcc -finstrument-functions.  It uses the i586 rdtsc
to record function entry and exit, so it's a lot more accurate than
10ms sampling by prof.
