the linker looks in cached directories for its libraries.  /home/ directories,
usually, aren't part of that set.  think you need to add the path[*], check out
'man ldconfig'.

[*] or, better, install the libraries in the designated directories, ie under
'/usr/[local/]lib64'.

Hi,

As jr suggests a standard 'machine image' package install of boost would 
likely solve the issue.

That said. Did you first try pointing to just where the boost libraries 
are located on your machine? This is done with:

--with-boost-libdir=LIB_DIR

It looks to me like from your earlier posts - and this latest - that you 
are finding the boost headers during configuration, but not the boost 
library when attempting to link a final executable.

I'd suppose if both your boost headers and libraries were installed in 
non-standard locations you might have to use both as in 
--with-boost=PATH and --with-boost-libdir=LIB_DIR.

I've not played with trying to use a personal install of boost like that 
during configuration. I wonder what will happen if the system 'OS image' 
already has boost installed in a standard - or somewhat standard way.

Guess, the hope would be only the ./configure specified versions would 
be used, but, I've not tried it. A $HOME install of any program 
dependency comes with more risk / potential instability.

Another thought, getting at basics, have you looked for the actual boost 
thread library on you machine (and/or in your home directory install) ?

On my Ubuntu 22.04 machine it's at:

/lib/x86_64-linux-gnu/libboost_thread.so

which is really a symbolic link to:

/lib/x86_64-linux-gnu/libboost_thread.so.1.74.0
