RTAPI_TASK_PLL_SUPPORT not present #81

Open narogon opened 4 years ago

narogon commented 4 years ago

Hi @sittner,

I've just installed new versions. (ec-debianized and hal components).

But when I load lcec with config file that contains refClockSyncCycles="-1" it says that RTAPI_TASK_PLL_SUPPORT not present. I've just downloaded a fresh linuxcnc 2.7.14 and applied the patch. Configured with./configure uspace , created the .deb packages and installed like always.

I'm running SMP PREEMPT RT Debian 4.9.168-1+deb9u4 (2019-07-19)

Any idea of what I'm doing bad? Any way to investigate/solve this?

I would really appreciate your help because I'm stuck with this and I'm so hopeful this version solve my syncs problems.

I've achieved run linuxcnc with pll but I don't know if something is wrong in my configuration or I miss something.

In https://github.com/sittner/linuxcnc-ethercat/blob/5399017a1b5887594186aac3722a1a51e0ea07ca/src/lcec_main.c#L395 it checks if RTAPI_TASK_PLL_SUPPORT is defined. I've searched where is defined it and discover that it is in rtapi.h after applying the patch.

`#if defined(RTAPI_USPACE) || defined(USPACE)

define RTAPI_TASK_PLL_SUPPORT`

But rtapi_uspace or uspace are not defined nowhere but config.h I added a #include config.h to lcec_main.c and now pll pin are created and no warning message is printed.

Is it correct???

Hi, @narogon Have you solved this problem？ How to do it? And does it support RTAI Debian?(Linux debian 3.4-9-rtai-686-pae #1 SMP PREEMPT Debian 3.4.55-4linuxcnc i686 GNU/Linux)

I explained in my last paragraph.

I added a #include config.h to lcec_main.c and now pll pin are created and no warning message is printed.

But I don't know if it is the correct way to solve this.

This worked for me aswell, i dont even know where the config.h is located in my system, i just wrote #include "config.h" in lcec_main.c My original problem was: undefined symbol: rtapi_task_set_correction

thank you narogon
