thanks for posting your source files with these i could
reproduce the DSO error, the problem is in the make for
the *userspace* bin/genserkins when using math functions not
provided by gomath,posemath etc.
Note: the bin/genserkins utility is undocumented and is likely seldom
used. it is buggy in all branches -- this doesn't effect realtime
modules using genser*.c files
force pushed dgarr/s_kins commit: 9af319596
(adds -lm in src/emc/Submakefile)
Note: the master branch is currently broken but
dgarr/s_kins is rebased to an older (working)
master branch

Thanks again for the prompt reply!
I build the newest commit but I'm still having the same issue after copying my config to the configs folder and the .c files to src/emc/kinematics:
I'm sorry to keep bothering you.

and they work for me so i have pushed a
'scratch' branch that you can try:
dgarr/aciera.0
github.com/LinuxCNC/linuxcnc/commits/dgarr/aciera.0
Please test.
If this works for you, i will modify dgarr/s_kins
to make it simpler for you to add an additional
kinematics method within dgarr/s_kins.

28feb20 dgarr/s_kins branch update (e10cc60d371):
28feb20 later: (eed4edd7e)
1) In genser-switchkins.c, support:
motion.switchkins-type == 2
2) provide template file named switchtype2funcs.c
demonstrating functions:
switchtype2KinematicsForward()
switchtype2KinematicsInverse()
3) demonstate usage in puma560-switchkins.ini
A user can now modify just one file (switchtype2funcs.c)
to add any code necessary to provide kinematics for
motion.switchkins-type==2
It is intended that user should not need to modify any
other files in order to maintain a common and stable
genserkins base. Bug fixes for genserkins should be
implemented in appropriate in-tree files.
Notes:
In the future, the switchtype2funcs.c template may be
used with other switchable kinematics modules (e.g.,
not limited to genser-switchkins).
Template Ref: github.com/LinuxCNC/linuxcnc/blob/dgarr/...s/switchtype2funcs.c

Notes:
switchkins-type==0 is default at startup
switchkins-type==1 is reserved (and used by existing
switchable kinematics modules)
switchkins-type==2 is supported but implemented only
by a template that user can modify
as requiredIn the future, the switchtype2funcs.c template may be
used with other switchable kinematics modules (e.g.,
not limited to genser-switchkins).

Thank you for your ongoing support!
Sadly it's not working for me on my linux mint machine:
I will setup a new machine tomorrow using debian buster and try again.

i found a mint18 virtual machine and was able to
replicate your result -- not a linker expert but
a minor reordering fixed for me on that machine.
Please try new branch: dgarr/aciera.1
and report (and include output from linuxcnc_info)
Supporting&testing every possible
distribution/architecture/kernel/release
is not always simple.
