[go-nuts] Re: Cross-compiled program for Raspberry Pi crashes

No, it’s not a cross compilation issue. Well, yes and no, the rpi is a 32 bit platform so some structures have a different size causing the offset of the field to be 32 but aligned, not the required 64 bit aligned. The play example shows the address of the field is not aligned on a 8 byte boun

Another option may be to run 32 bit raspberian OS and compile in a virtual machine and compile it there, perhaps. VirtualBox comes to mind. On Mon, Aug 13, 2018 at 1:52 PM, Stephan Mühlstrasser < stephan.muehlstras...@gmail.com> wrote: > > Am Montag, 13. August 2018 22:36:56 UTC+2 schrieb Dave C

[go-nuts] Re: Examples testing with two newline, but only one newline

Looks like a bug to me. I would suggest you open an issue. It is not clear to me what the intended behavior is. It is documented that examples strip some white space when comparing output. So it may be intentional that multiple white space lines are removed from the expected output. In that cas

[go-nuts] Re: Cross-compiled program for Raspberry Pi crashes

I don’t think that will help. The problem is not cross compilation. The problem is when run in a 32bit environment the offset of that field is not guaranteed to be aligned to 8 bytes. You’ve got a 50/50 chance that each allocation will be properly aligned. -- You received this message because

It is still there because someone if (hopefully) benificently name squatting there with the same package. It went away and broke things. The person who owns jteeuwen is not Jim (the original owner), and has put back the go-bindata repo to avoid a breakage. It could be far worse. On Mon, 2018-08-13

Re: [go-nuts] Re: Cross-compiled program for Raspberry Pi crashes

It’s a bug in the library if it uses 64 bit atomic operations without ensuring 64 bit alignment. Putting the alignment-required field at the top of the struct is the traditional method. //jb On 14 Aug 2018, at 08:45, Stephan Mühlstrasser mailto:stephan.muehlstras...@gmail.com>> wrote: Am Mont
