Hello Etherlab community, I am trying to set up a new realtime PC and would like to use the current version of Matlab/Simulink (and possibly future versions in the next years). I installed the etherlab toolchain as of March 24th 2020 from the source-forge hg repos: etherlab-code (1198 (4d38cecf1184); 2020-01-09), etherlabmaster-code (2724 (fff0749b52f5); 2020-01-24) and pdserv (version 3.2.0, rev 651, 2020-01-10).
If I install everything on Matlab R2018b, the model compiles and can be run. On R2019a (and R2020a), I receive errors and can not build (see log at the end of the mail). The log was created with a new Simulink model from scratch. Is there a known compatibility list of versions of Matlab and Etherlab? So does this work at for someone else? Then I would continue looking into this. Independent from the configuration in the question above, I also have a patched version of EtherLab that removes pdserv and inserts the external mode (see post in etherlab-dev mailing list). This worked well until R2018b and did not work any more on R2019a (with similar error messages). The patch is based on etherlab-code rev 1099 (2016-01-28). I successfully rebased the patch until rev. 1142 (2018-01-18). Going further would take a high additional effort due to the major changes in hrt_main.c. Since the whole purpose of the rebase is to get it running on the latest version of Matlab (and potential future versions), I would like to know, if this is possible in principle or if there are major changes in Matlab R2019a declining this. Thank you and best regards, Moritz Schappler (Research Assistant at the Institute of Mechatronic Systems at Leibniz Universität Hannover) P.S. Please forgive a potential double-post, as I am not sure if the same email from March 24th got delivered. > ### Creating > /home/schappler/IMES/REPO/ethercat/etherlab-slaves/ixxat/new_2019a_etl_hrt/new_2019a.mk > from /mnt/data/usr/local/MATLAB/R2019a/rtw/c/etherlab/etherlab_hrt.tmf > ### Building new_2019a: > /mnt/data/usr/local/MATLAB/R2019a/bin/glnxa64/gmake -f new_2019a.mk > INCLUDE_MDL_TERMINATE_FCN=1 ISPROTECTINGMODEL=NOTPROTECTING > CC new_2019a_capi.o > CC new_2019a_data.o > CC new_2019a_header.o > CC rtGetInf.o > CC rtGetNaN.o > CC rt_nonfinite.o > CC ecrt_support.o > CC new_2019a.o > CC hrt_main.o > g++ -o ../new_2019a new_2019a_capi.o new_2019a_data.o > new_2019a_header.o rtGetInf.o rtGetNaN.o rt_nonfinite.o ecrt_support.o > new_2019a.o hrt_main.o -L/usr/local/lib -lm -lpdserv -ldl > -lrt -pthread > new_2019a.o: In Funktion `new_2019a_step': > new_2019a.c:(.text+0x15): Nicht definierter Verweis auf `ecs_receive' > new_2019a.o: In Funktion `new_2019a_initialize': > new_2019a.c:(.text+0x2c2): Nicht definierter Verweis auf `ecs_init' > new_2019a.c:(.text+0x316): Nicht definierter Verweis auf > `ecs_start_slaves' > new_2019a.o: In Funktion `new_2019a_step': > new_2019a.c:(.text+0x17c): Nicht definierter Verweis auf `ecs_send' > new_2019a.o: In Funktion `new_2019a_terminate': > new_2019a.c:(.text+0x356): Nicht definierter Verweis auf `ecs_end' > collect2: error: ld returned 1 exit status > gmake: *** [../new_2019a] Error 1- -- __________________________________________________________ M.
