When I try to launch the editor It says “Illegal instruction”, I’m using the self extracting package.
Anyone else have the same message?
Are you sure you are running on amd64 architecture?
Yeah, I can run 5.6.0xb3 fine.
Same issue here with Debian Stretch 64bits (I’m sure 
)
Version 5.6.0xb3 was working fine except the few known bugs.
It might be useful to know that I use a quite old CPU : Core2Duo E6750
Sometimes updating the microcode can fix this.
It’s possible that some dependency inadvertently added a new instruction requirement.
Can you post a core dump of your crash? (e.g. Take A Core Dump: What to do when your app crashes on Linux – Xojo Programming Blog )
I will wait to update until I see the results of this. Thanks for the great work Tak, the Linux builds are coming fast and hard.
Hi Tak,
It seems the crash does not generate a core dump file, I don’ know why…
I compiled a test program with a segmentation fault, and got the core dump so I’m sure my terminal is set up correctly.
If you have any suggestions, I will try them. If not, I hope Hoogin has more luck.
Ok I figured it out. The problem was that I was launching the Unity executable from a folder where I didn’t have write permission.
Here is a link to download the core dump (the file is 15MB, couldn’t upload it on the forum):
Here is my core dump. Core dump link.
I’m running an older cpu on this machine, AMD Phenom II x4 955.
Ok, it looks like one of our middleware libraries was built to use sse4.1 - we’ll address that.
i got same Illegal instruction (core dumped) but guess Taks on it
Thanks
Okay, Thanks Tak!
I can subscribe to this problem too. Same thing happened to me.
lucas@lucas-A780GM-A:/opt/Unity/Editor$ ./Unity
Illegal instruction (core dumped)
Uploaded the core file
2951067–218791–core.zip (2.31 MB)
Please build it without sse4.1 requirement, I have Q6600 and it supports only sse3 
Some issue…
Anybody try use 5.6.0b8? It is steel have issue with Illegal instruction at processors without SSE4.1?

Looks like you guys are on it, but I also tried 5.6.0xb8 with the same illegal instruction error. The last version I tried, 5.1.0f3 worked fine. (I know, its old)
