--- Comment #4 from Rodrigo Campos <rodrigo at sdfg dot com.ar> ---
I think I'm hitting a similar issue, although not when using sse code in my
case.
I'm working on a (shared) library that uses P99: http://p99.gforge.inria.fr/. I
just use it as a git submodule on commit 59e08b2, so not linking nor anything
"wierd" there, just as it was part of my source code.
When I compile the shared library, of course, no error is thrown. But when I
try to link agains it, the same "undefined reference to" error to a bunch of
P99 functions. For example something like this is shown:
./liborwl.so: undefined reference to `mtx_lock'
./liborwl.so: undefined reference to `p99_count_destroy'
./liborwl.so: undefined reference to `p99_rand'
Lot of them, I didn't check all, have the "always_inline". And some also have
the "warn_unused_result" gcc attribute or something else.
Also, I'm using gcc 4.7.2 (in debian stable). If I use gcc 4.5 the code
compiles and link okay, but when I run the executable it seems there is a
memory corruption and nothing works as expected.
Is this "-finstrument-function" flag still supported ?
Thanks a lot,
Rodrigo
