I could at least remove the "dac~: bad vector size" error but still there's another error "pd-to-gui socket: Bad file descriptor" which I believe is related to "pd/src/s_inter.c" file.

By mixing these source files you may be creating two sources of truth.
For example, sys_flushtogui-- the function
that has the pd-to-gui error-- uses some global variables in Purr
Data. In Pd Vanilla the "pd_this" thread-local struct
is used instead. Initializing one somewhere in the codebase and using
the other somewhere else could be a
source of error-- for example if sys_guisock is uninitialized here.
