Hello,

Both of these INDI devices are crashing. Here are their errors.

2020-08-17T00:49:37: Driver indi_gpsd: indi_gpsd: symbol lookup error: indi_gpsd: undefined symbol: _ZN4INDI13DefaultDeviceD2Ev


2020-08-17T00:54:27: Driver indi_qhy_ccd: indi_qhy_ccd: symbol lookup error: indi_qhy_ccd: undefined symbol: _ZN4INDI7CCDChip8setFrameEiiii

A clear night and an INDI update two days ago come crashing down. Looks like a bad update.

Hello,

I have been reviewing comments like “undefined”. Many hits are identified. All are related to Ubuntu. Under Ubuntu, a promised update resolved this issue. To me, Libinidriver1 has changed. I suspect that this update is the cause. Something is not initializing this value. It is either missing or disabled.

I isolated the GPSD service with EKOS. INDI_GPSD instantly fails. INDI is broken. GPSMON works fine. CGPS works fine. INDI_GPSD is missing a key value being defined. INDI_QHY_CCD is also missing a key value defined. The udevadm rules are working correctly.

I am requesting assistance. Moving to INDI Library 1.85 is the root cause. Something in it for Raspbian is missing or disabled.

Hello

After fixing log permissions (root had many folders locked), I now have INDI chattering. Here is INDI logging.

Hello,

Using LDD and NM, I found the reason. Libindidriver.so.1.8.6 does not contain the INDI messages. The EOF is that the symbol is not found. I am filing a bug.

No other of the pieces which build both drivers use these symbols. INDI is querying the drivers and libindidriver.so.1.8.6 can’t answer. INDI throws the error.

As I type, this suggest that both drivers cannot answer INDI. Maybe libindidriver is supposed to point to indi_gpsd or indi_qhyccd for the answers. But, neither driver’s cpp, h, or make files define the INDI need.

Hello,

Why this discussion and finding? Because drivers require insight into the workings of the big operation.

Use: ldd
Use: nm

Are tools which help peek into what it used to build a driver. A driver is dependent on being told everything about its parent’s use. And, the driver’s talk to the parent is strictly controlled.

These drivers, indi_gpsd and indi_ghy_ccd are dependent on libindidriver. Libinidriver is the strict communication list to the parent. This limits useless chatter.

I did create a bug. I will investigate if using a different libindidriver has a difference.

Hello,

Thank you Radek and Jasem for being a part of the larger team building KSTARS, ECHOS, and INDI. This morning, an update was pushed to AstroBerry. The immediate crashes are fixed. Operational readiness is on the horizon for the next clear night. Good Job!
