Maybe this helps:
It happens to me with linux-image-rt-686-pae (3.2+46+deb7u2) and linux-image-3.2.0-6-rt-686-pae debian wheezy.
With deb7u1 and linux-image-3.2.0-5 no problem.
What kernel are you using?
Many thanks for the quick response.
Right now I am using 4.9.98-rt76 (SMP PREEMPT), on Linux MINT 18.3 x64, but I think I observed similar effects on Debian Stretch with linux-image-4.9.0-6-rt-amd64 kernel package. I will try to repeat the build process on Debian Stretch again and post back.
ec-debianize (latest commit, b127d07 ) and Linuxcnc (2.7.13) both compiled sucsesfully and work well on this kernel (4.9.98-rt76). Kernel was patched with rt-preempt patch and built from source without any problems.
*** To make sure that ethercat drivers are loaded, I ran the following commands (single slave connected to the master):
~/src/ec-debianize/ec-debianize $ lsmod |grep ec_

For the reference, I have also attached ec-debianize build and install logs. 00_ec-debianize_build_log.txt 01_ec-debianize_install_log.txt
I can confirm the same error when building on Debian Stretch with stock rt-preempt kernel (4.9.0-6-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.88-1+deb9u1 (2018-05-07))

Here is another update:
I get the same error as before when trying to compile the code with latest commit (407698b )
make && make install (without using dpkg-buildpackage) seems to compile without errors (same kernels used as before):

However, when trying to start the hal script (which works quite fine on older rtai build), I get the following error:
$halrun -I srm_amc_fullpdo.hal
Note: Using POSIX realtime
lcec: dlopen: /usr/lib/linuxcnc/modules/lcec.so: undefined symbol: ecrt_slave_config_sdo
srm_amc_fullpdo.hal:7: waitpid failed /usr/bin/rtapi_app lcec
srm_amc_fullpdo.hal:7: /usr/bin/rtapi_app exited without becoming ready
srm_amc_fullpdo.hal:7: insmod for lcec failed, returned -1
halcmd: exit
I am trying to get the linuxcnc-ethercat package working on these kernels since support for rtai builds was dropped in latest versions of ec-debianize. Older rt-preempt kernels do not seem to make much sense since older rtai kernels perform much better.
Kind regards
@tstaroveski Hi, I have the same problem like you,"undefined symbol: ecrt_slave_config_sdo" etc. And I still don't know how to solve it, Could you give me some advices? Kind regards.
src/user.mk
install: lcec_conf mkdir -p $(DESTDIR)$(EMC2_HOME)/bin mkdir -p $(DESTDIR)$(RTLIBDIR)/ cp lcec_conf $(DESTDIR)$(EMC2_HOME)/bin/
Did anyone ever figure out this problem?
Dear Mr. Ittner,
Thank you very much for the great work!
I would like to report a problem which occurs while building the packagage using dpkg-buildpackage command. The problem seems to be related to one of the Makefiles (presumably src/realtime.mk).
After cloning repository and running dpkg-buildpackage, I get the following error:
It would seem that linuxcnc-ethercat/usr/lib/linuxcnc/modules/ directory is not created during package build.
