[djandruczyk]

Just installed megatunix and keep getting a segmentation fault

0.9.22 is old, retry with 0.9.23

traces are only good if you configured megatunix with "--enable-debug".

[mjohnson575]

Thanks. Don't know how or why it downloaded 9.22

[djandruczyk]

Did 0.9.23 solve the issue?

[mjohnson575]

No. I even got 9.24 and still get segfault. Could it be that I don't have the ecu hooked up?

[djandruczyk]

No. I even got 9.24 and still get segfault. Could it be that I don't have the ecu hooked up?

Are you choosing offline mode? which family and firmware did you choose?

0.9.24 is highly developmental, and only available via git. If you're going to use that YOU MUST compile it with debugging symbols (./configure --enable-debug ; make clean ; make ; sudo make install), and provide backtraces AS WELL AS CONTEXT to the crash. (i.e. where/when it does it, what was happening, what EXACT firmware you have on your ECU, and so on.

A non-debug build doesn't tell me anything in a backtrace, whereas a debug build will usually give me line numbers and a place to hone right in on.

[mjohnson575]

Yes I choose offline mode. Im using ms1 029y4 I think that's right. Im going to try and load 9.23 here in a few minutes. Happy new year

[djandruczyk]

OK, offline mode has several issues in the released versions. I'llsee if i can accelerate the release schedule for 0.9.24

[mjohnson575]

Thanks! Got it working last night in offline mode. Even got guagedesigner to work. Thanks for the support.
