[lttng-dev] liblttng-ust-cyg-profile.so not found

[Alexandre Montplaisir]

On Ubuntu/Debian, there is no "lib64", it's /usr/lib/x86_64-linux-gnu/

If you installed UST from the distro package, it should be at:
/usr/lib/x86_64-linux-gnu/liblttng-ust-cyg-profile.so.0

(the .so symlink is only installed by the -dev package)

If you installed from source, it would be at:
/usr/local/lib/liblttng-ust-cyg-profile.so


Quick tip: you can use:
 dpkg -L liblttng-ust0
to list the files installed by a package.


Cheers,
Alexandre
