Ah! That explains much. Thank you.
I still get results that I don't understand. This is the beginning of
what I get for profiling my executable:
-----------------------------------------------------------------
Flat profile:
Each sample counts as 0.01 seconds.
no time accumulated
% cumulative self self total
time seconds seconds calls Ts/call Ts/call name
0.00 0.00 0.00 56133 0.00 0.00 data_start
0.00 0.00 0.00 19 0.00 0.00
MG_sigma2_Theta_threaded
-----------------------------------------------------------------
There's a record of calls but not of times, and _nothing_ for the
library functions. The library and this executable are all built
together in one big ./configure && make.
I don't know whether I need to do more than add -pg to the CFLAGS when
building the library or whether it's simply gprof I'm not using correctly.
Thanks again,
