How to build the 64 bit version?


Trying things out the default 32bit build works great, but 64bit build gives the error LLVM ERROR: SSE register return with SSE disabled, which I understand to have something to with not needing or using floating point at OS level?

Is there a away to build the 64bit version?

Thanks in advance.

The 64bit build support is not ready yet. There is still more work needed to be done due to how obscure the x86_64 architecture is on the low level side.

Thanks for the fast reply. I am still learning Rust but have a lot of different x64 hardware(desktop up to 80 core HP DL980’s), if you need help testing on real metal I am happy to find cycles.


That is simply not true. We got x86_64 support. You just have to uncomment line 3 in Makefile, and then build.

Stratact is right, it is brokrn right now

Oh, it is? What’s wrong with it?

When building it gives the error LLVM ERROR: SSE register return with SSE disabled

Seem to be fixed as of last nights build? Are there any plans for a build server? We have sent up Jenkins with GIT checkout, not sure if that would work with rust, but I am happy to set one up if there is need.

We already have a build server at
