Segmentation fault with aes.cpp in Examples_Rpi #30
Comments
|
hello,
the code is tested in raspberry pi 2 not 3 , but there should be no
difference.
i need more insights of the problem, can you add some prinf in various
places of the code and identify the line of the segmentation fault ?
if the line has a function do the same in the function and identify where
the bug is, this way i can help you more.
thank you
GS

I am using Raspberry pi 3 which is running Raspbian OS. I know that the
libraries are installed fine because when I run test_vectors.cpp it
produces the expected output.
Would you have any ideas as to why this would be happening?

Hello thanks for getting back to me. I see. So I do have a printf in the main as the first line but even that is not printed which makes me wonder if the error could be because of faulty linking of the libraries from the makefile. Do you think that would be an issue? |
|
can you try : sudo make clean I remember when I was initially building the library I had soem segmentation faults, cant recall the reason, but i think it was something with the install or the sudo. other than that, I or you since i yet not own a V3 have to check the CFLAGS I assume they are correct else the make install would fail. We will manage to solve the problem. |

do we have an update from the segmentation fault from your side ? |
|
Not yet, I have not been able to go to work on it. From what I remember though there wasn't any error on installing but I'll get back to you once I reinstall. |

So I was looking further into the architecture type of my pi and this is what I found when I did a cpuinfo. I think I'll have to change the flags for the compiler accordingly. What are your thoughts? |

i will have a deeper look to arm7 v arm6 flags and get back to you.

can you run cpp -dM ./dummy.hxx |\grep -i -e linux -e arm -e ARDUINO_X86 |
|
@jaggarwal96 can you please try with the changes pointed our at #32 issue, and report back? the file change is : AES_config.h at line 8 |
In order to use this command you have to do |

Here is the output |
So I followed the steps you have in the readme to install the library and run it on a raspberry pi. However when I try to run the aes.cpp (with no modifications) I get a seg fault.
I am using Raspberry pi 3 which is running Raspbian OS. I know that the libraries are installed fine because when I run test_vectors.cpp it produces the expected output. One thing is notice is that the makefile generates a .so file for aes.cpp but for test_vectors is only creates an executable which makes me wonder if something in the makefile is not working.
Would you have any ideas as to why this would be happening?
