Odd, it seems to be being compiled (this is an extract from the buildbot log)

Code:

And it seems to appear in the .deb files that I have built (so I would expect it to be in the buildbot ones)

Code:

andypugh@rm-one:~$ dpkg -c linuxcnc_2.9.0~pre0_amd64.deb | grep sendkeys
-rwxr-xr-x root/root     14608 2019-06-02 23:52 ./usr/bin/sendkeys

being a smart A£$£, I thought I'd just download sendkeys.c from linuxcnc git and run halcompile....

I ended up with this...

Code:

rob@RobsCNC:~/Downloads$ sudo halcompile --install sendkeys.c 
[sudo] password for rob:

am I doing something wrong?

where should I look for sendkeys.c on an linuxcnc.iso && upgrade to master via buildbot? {I check for updates daily, so its always on the latest master}

That really shouldn't be necessary. But also should work.

sendkeys.c:202:5: warning: implicit declaration of function ‘signal’; did you mean ‘strsignal’? [-Wimplicit-function-declaration]
signal(SIGINT, exit_handler);

I think that you might need the kernel headers to compile it.

To be honest I think that the best fix it so figure out why you are not getting the compiled module automatically with LinuxCNC.

I can't compile it with halcompile either, by the way. I think that it needs to be given the paths to various includes that halcompile doesn't do.

It compiles OK as part of a full LinuxCNC install.

nope,

I've given it the paths to all of the includes:

Code:

#include </usr/include/linuxcnc/rtapi.h>
#include </usr/include/linuxcnc/hal.h>
#include <linux/uinput.h>
#include </usr/include/linux/unistd.h>
#include </usr/include/linux/fcntl.h>
#include </usr/include/stdio.h>
#include </usr/include/c++/8/stdlib.h>
#include </usr/include/linux/string.h>

No dice.

Code:

this was after removing (completly) linuxcnc using synaptic and reinstalling from buildbot master moments ago.

baffled!

{thanks for your help / taking the time to check this thread out it is much appreciated}

just for fun.....

I did a complete removal of linuxcnc again using synaptic and reinstalled 2.8.1 from buildbot.....

Code:

rob@RobsCNC:/usr/lib/linuxcnc/modules$ ls s*
sample_hold.so   serport.so            sim_parport.so      steptest.so
sampler.so       setsserial.so         simple_tp.so        streamer.so

scarakins.so     sim_axis_hardware.so  sphereprobe.so      supply.so
scope_rt.so      sim_encoder.so        spindle_monitor.so
scorbot-kins.so  sim_home_switch.so    spindle.so
select8.so       sim_matrix_kb.so      stepgen.so
rob@RobsCNC:/usr/lib/linuxcnc/modules$ 

am I missing something as a noob?

Is "thermistor" there?

If you grab the deb directly from the buildbot, can you see the file in it with dpkg -c ?

Code:

dpkg -c //name//of//deb//file// | grep sendkeys

buildbot.linuxcnc.org/dists/

no {not in 2.8.1 & master [I just updated to master]}

Code:

rob@RobsCNC:/usr/lib/linuxcnc/modules$ ls t*.*
thc.so      threadtest.so  time.so         tripodkins.so      trivkins.so
thcud.so    timedelay.so   toggle2nist.so  tristate_bit.so
threads.so  timedelta.so   toggle.so       tristate_float.so
rob@RobsCNC:/usr/lib/linuxcnc/modules$ 

Could I be missing a dependency? [I would have thought that any dependencies for linuxcnc would be installed by default as part of the linuxcnc.iso install from bootable usb?

I have the following installed:
linuxcnc-doc-en
linuxcnc-uspace
linuxcnc-uspace-dev

do I need to install linuxcnc-uspace-dbsym??? (what are the debug symbols for?)

well sendkeys is within the *.deb..... but at what point is it compiled to a sendkeys.so module?

Code:

rob@RobsCNC:~/Downloads$ dpkg -c linuxcnc-uspace_2.9.0~pre0.3688.ge6aec2fd2_amd64.deb | grep sendkeys
-rwxr-xr-x root/root     14592 2021-03-20 07:44 ./usr/bin/sendkeys
-rw-r--r-- root/root      2313 2021-03-20 07:44 ./usr/share/man/man1/sendkeys.1.gz

anyway to run an install giving a complete output of what was installed

One hell of a mystery!

Code:

rob@RobsCNC:/$ sudo find -name 'sendkey*.**'
./home/rob/Downloads/sendkeys.c
./usr/share/man/man1/sendkeys.1.gz
rob@RobsCNC:/$
