host vs target

[aoplik]

This is mostly a naive question.
I follow installation steps and can run uftrace locally at my host.
My target machine though isn't straightforward.
To check quickly I copied uftrace binary and the dependent libs to target system.
However getting this error

./uftrace fib
ERROR: ld.so: object 'libmcount-fast.so' from LD_PRELOAD cannot be preloaded: ignored.
uftrace: record.c:1437:update_session_maps
ERROR: cannot find map files: No such file or directory

Is there a recommended steps to get uftrace compiled and installed in one place and used elsewhere ?

Thanks!

Can you tell uname -a of both machines?
It is best to build it on the target machine when no binaries are available...

Sorry for the late reply. uftrace will search the library in the specified location in your config as well as the default library location (e.g. /usr/lib). If you built it from source, please check the libdir in the .config file. And place all libmcount libraries at the same location in your target system.
