Segmentation fault upon connect #1

Open mangobot opened 4 years ago

mangobot commented 4 years ago

Hi, I'm using this python binding sdk on an ARM7 Debian platform. Ended up getting a segmentation fault error that gives no debug feedback when I tried to connect to my Pentax KP, as follows:

ricoh_camera_sdk.CameraDeviceDetector.detect(ricoh_camera_sdk.DeviceInterface.USB) Device 0 (VID=25fb and PID=017f) is a Ricoh Imaging PENTAX KP. [<ricoh_camera_sdk.CameraDevice object at 0xb69e4520>] ricoh_camera_sdk.CameraDeviceDetector.detect(ricoh_camera_sdk.DeviceInterface.USB)[0].connect(ricoh_camera_sdk.DeviceInterface.USB) Device 0 (VID=25fb and PID=017f) is a Ricoh Imaging PENTAX KP. Segmentation fault

Not really sure how to proceed from here, any ideas on how I can more thoroughly debug?

As an update, ran it on an X64 debian system, which seems to not have the segfault issue. Perhaps there's a problem with the Ricoh ARM SDK? Would be interesting to be able to use this python interface on Raspberry Pi's and the like.

Hi, thanks for report. The libRicohCameraSDKCpp.so seems to depend on the libmtp.so.9 in the same folder. Enter the sdk's lib folder and execute the following command.

$ ldd libRicohCameraSDKCpp.so

If you have libmtp.so on your system, it can cause a crash.

There are several ways to get around that.

I hope this helps.
