Not in general.
pumakins is an example of a kinematics module that actually is a
combination of several source files (in addition to pumakins.c,
_posemath.c and sincos.c are included). halcompile does not handle such
components. (this dependency is a bit hidden, it's written in
src/Makefile, search for pumakins)
You didn't show the error, but I assume that it was something like
(assuming uspace)
pumakins: dlopen: ...: undefined symbol
the named symbol (such as pmRpyQuatConvert) comes from one of those
other source files that is linked into the pumakins component when built
inside LinuxCNC.
tripodkins, on the other hand, not only compiles with halcompile, but
the result will also 'loadrt'.
By using Makefile.modinc directly, you should be able to build C
components from multiple source files. However, this is not documented
or tested, so it's probably broken and how would you know about it
anyway?
Well, here, I at least wrote a test. It passes in master branch with
uspace.
