Used in papi
First, add the following to your
[dependencies] papi-sys = "0.1.0"
Before building, ensure that PAPI is installed on your system.
The purpose of this crate is to provide 1:1 bindings for papi.h. PAPI is a library that provides a consistent interface to hardware performance counters. Visit the PAPI website for more information.
Note that this crate does not provide a high-level interface to PAPI.
There are two environment variables to specify a custom PAPI library path:
PAPI_PREFIX: required to generate
LD_LIBRARY_PATH: required to dynamically link
Let's assume you installed PAPI in
/opt/papi/5.7.0/, then you can test by
$ PAPI_PREFIX=/opt/papi/5.7.0/ LD_LIBRARY_PATH=/opt/papi/5.7.0/lib:$LD_LIBRARY_PATH cargo test
To avoid setting
LD_LIBRARY_PATH, you can configure the search path
globally by running:
$ sudo echo "/opt/papi/5.7.0/" > /etc/ld.so.conf.d/papi.conf $ sudo ldconfig
