linuxcnc trajectory planner

he Grotius ... sorry for stupid question ... not read all post of these thread .... but is possible to install these project or only rip-install? can damage somethings if try on little scara your code? custom kins is the same as 2.10?

regards

Hi Bkt,

You can install it "rip" only, but you can not run the new trajectory planner. It's still being coded.

custom kins is the same as 2.10?
I don't know wich kins versions are in. Its a recent linuxcnc git clone.

Still doesn't work without copying 'liblinuxcnchal.so.0' to 'root/lib':

Just reinstalled the OS (LMDE 6) and while my regular linuxcnc rip install works I still have to copy copying 'liblinuxcnchal.so.0' to 'root/lib' to get it to start from your repo.

Hi Arciera,

Thanks for trying this out.
Maybe i have an idea.

I can check the regular make process --verbose output.
Remove one lib from the rtlib that uses liblinuxcnchal.
Then invoke a make --verbose command and check the output.
In this output we can see compile flags. Then maybe we miss a compile flag.

If we miss a compile flag, we add it to the edited motmod.so or tpmod.so (cmake projects)

Let you know soon!

Hi Arciera,

For test, i removed homemod.so from the rtlib and did :
~/linuxcnc_trajectory_planner/src$ make BUILD_VERBOSE=1

Output of this:
Reading 203/203 dependency files
Done reading dependencies
Reading 266/266 realtime dependency files

Linking ../rtlib/homemod.so
ld -d -r -o objects/homemod.tmp objects/rtemc/motion/homemod.o objects/rtemc/motion/homing.o

chmod -x ../rtlib/homemod.so
You now need to run 'sudo make setuid' in order to run in place with access to hardware.
is a prefix used to pass options directly to the linker. sets the runtime library search path for the executable

Now these are added here and here we have to use as this is the cmakelists.txt current directory.
Relative from here the filepath is compiled with it.

I hope this solves the problem.
