Sigill crash in RPI 2 with allsky

[anismo]

I am trying to get this running on my Raspberry PI 2 board and I am trying to get it connect to my ASI120MC USB 2.0 camera.

However, following the instruction here, capture binary crashed with sigill and I realized that the Makefile is using -march=armv7 and my board is armv61. Once I removed it and recompiled capture, it started up fine however, the libAsiCamera2.so is probably also compiled with armv7 and is crashing with SIGILL.

Any chance I can get the libASICamera2.so build for armv6? Thanks!

Hi, Can you give me the content of this command?

cat /proc/cpuinfo

That will help me find what versions of the Pi are compatible.

I have updated the Makefile and included armv6 libraries. Open the Makefile and change the first line to armv6, then run make capture again. Can you let me know if it compiles properly? Thanks

Hi Thomas, Thank you for your response

Here is the CPU info. I will update the makefile (I did change it and compile it already and the capture program itself works ok now - Earlier, the capture program itself hit sigill. However, now the probelm is that the shared library for the camera has the same problem . Do you also compile that library?)

I just noticed that you have added new libraries. I Will build and update later today after work! Thank you

I tried the new Makefile but it fails with the cross compiler not being available

FYI: The install script has to be changed to copy the libASICamera2 libraries from the arvm6/armv7 subfolder as well. I noticed that with the latest pull, the shared libraries are soft links to libASICamera2.so.0.4.0929 however, that library itself is not included.

Quick update:

Instead of the shared library (which is a softlink), I switched to the included static library for armv6 and compiled it and it loads up (Awsome!)

I hacked up the Makefile

1. In the Armv6 , the make file tries to look for arm-bcm2708hardfp-linux-gnueabi-g++ and this is not available (only arm-linux-gnueabihf-g++ is available). So I switch to using arm-linux-gnueabihf-g++

2. Instead of shared library -lASICamera2.so, I switch to static compile

capture:capture.cpp $(CC) capture.cpp -o capture $(CFLAGS) $(OPENCV) lib/armv6/libASICamera2.a -lusb-1.0

Once I compiled it, the app started with no crash and started to take images with the ASI120MC USB 2.0 camera (though it was blank but that could be my settings that I need to check now)

[thomasjacquin]

Thanks for the debugging on your side. I have updated the README and re-added the shared libraries. I compiled using the armv6 and the armv7 flag without issues on my armv7-compatible Pi2. I will close the issue for now. I'll re-open it if you come across any issues

[anismo]

Thank you so much! This is such an useful program. I got it working with my ASI224MC . I probably need to update firmware on my ASI120MC (it only gives black frames regardless of exposure).
