Troubleshooting Typesense Binary Segmentation Fault on a Mac
TLDR Daniel sought help for a segmentation fault while using Typesense on a MacBook Air. Kishore Nallan guided them through the debugging process and suggested that it might be a compatibility issue with the Mac OS version. Daniel plans to try building Typesense on their own.

02:19 PMHey guys, probably a noob question but I’m trying to run the typesense binary on mac and keep getting a segmentation fault… do you have any ideas how I can debug this or figure out what’s going on?

02:19 PMCan you please tell me what version of Typesense you are running? Also, are you on the M1 mac?

02:23 PMI just downloaded the binary and ran it on my mac, and it is running fine. We have also not received a report on this issue given that 0.20 has been out for a few weeks now.. So I wonder what's happening.
Daniel
Daniel
02:23 PMCan I run it in verbose mode or output the error somehow?
Kishore Nallan
Kishore Nallan
02:23 PMIs that all you get when you run it?
Daniel
Daniel
02:24 PMYes, I just download the binary and used tar to unzip it. It just prints out that single line.

02:25 PMCan you do this:
The sum should be
md5sum typesense-serverThe sum should be

Daniel
02:26 PMMD5 (typesense-server) = a7cc212256a076fc6b9ddbb32351b3d8Kishore Nallan
Kishore Nallan
02:26 PMYeah that matches. :thinking_face: What version of Mac OS are you on?
Daniel
Daniel
02:27 PMmacOS Catalina: version 10.15.7 (19H1030)
02:28
Daniel
02:28 PMLet me try run it on my Big Sur mac…
Kishore Nallan
Kishore Nallan
02:28 PMThe only way to troubleshoot this will be to enable core dump and debug that, as per https://stackoverflow.com/q/9412156/131050
Daniel
Daniel
02:41 PMIt seems to run on my mac with Big Sur
Kishore Nallan
Kishore Nallan
02:43 PMOh I see. The build itself is created on Big Sur, so I wonder if it is a compatibility issue with older versions. Very difficult to handle this given the ever moving OS versions.
Daniel
Daniel
02:48 PMOk no problem, I’ll try build it myself later and see if that helps.
02:50
Daniel
02:50 PMThis is all I was able to get from the core-dump… not sure if it’s useful. I haven’t used c++ in a long time so not really sure what else I could try.
