ERROR: ld.so: object '/usr/lib/libprofiler.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Something seems to be wrong with libprofiler.so, at least in Ubuntu Xenial.

Doing this, for instance:

LD_PRELOAD=/usr/lib/libprofiler.so CPUPROFILE=cpu_profile ./something

leads to this:

ERROR: ld.so: object '/usr/lib/libprofiler.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

I've also tried supplying the -lprofiler option to gcc, but that also seems to have some problem using libprofiler. For instance:

 g++ ./something.cc -lprofiler
/usr/bin/ld: cannot find -lprofiler

Admittedly, this is my first attempt to use google-perftools, so maybe I'm doing something obviously wrong.

Sorry. I really didn't have libgoogle-perftools-dev installed. I was sure I did.
