Above package provides around 38 .la files. I am not quite sure yet
about hamlibtcl.la, libhamlib++.la, libhamlib.la and _Hamlib.la. Maybe
they can go -- will look into that in next days.

But the other ones are plugins (or backends in hamlib terms) which get
loaded via libltdl according to the radio tranceiver family in question.

See as an example the following strace for calling the simple frontend
(rigctl) for the Kenwood TS-570 tranceiver (Model 204).

strace -e open rigctl -m 204
open("/etc/ld.so.cache", O_RDONLY)      = 3
open("/usr/lib64/hamlib/libhamlib.so.2", O_RDONLY) = 3
open("/lib/libpthread.so.0", O_RDONLY)  = 3
open("/lib/libc.so.6", O_RDONLY)        = 3
open("/usr/lib/libltdl.so.7", O_RDONLY) = 3
open("/lib/libm.so.6", O_RDONLY)        = 3
open("/lib/libusb-0.1.so.4", O_RDONLY)  = 3
open("/lib/libdl.so.2", O_RDONLY)       = 3
open("/usr/lib64/hamlib/hamlib-kenwood.la", O_RDONLY) = 3
open("/usr/lib64/hamlib/hamlib-kenwood.so", O_RDONLY) = 3
open("/dev/ttyS0", O_RDWR|O_NOCTTY|O_NONBLOCK) = 3


If I read the discussion correctly we will still need to keep these .la
files around.

Regards,
