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

[Suchakrapani Datt Sharma]

Check if the liblttng-ust-cyg-profile.so is present in system using 'locate'. On
my system its in /usr/lib64

Then give the absolute path -

*LD_PRELOAD=/usr/lib64/liblttng-ust-cyg-profile.so* appname

This works for me.
