Another failing build

Hi,

Thanks for all the work done on llgo.

Is there a way I can deterministically compile ? Following the instructions at https://github.com/llvm-mirror/llgo it simply checks out master for llvm, clang and llgo.

I believe it would be really helpful to provide a few tags or revisions that are known to work.

I have this error currently:

...

Ideally the LLVM release tags would be usable. I don't know if they are - quite possibly not, since llgo is not part of the release testing. Until it is, I'm not sure there is a very good solution here.

In another thread I mentioned that I intend to package llgo as a "snap". Assuming I can carve out the time for this, I'd also like to set up a build bot (again), and the waterfall results could be used to identify working revisions.

I have this error currently:

The particular error you're getting looks like the LLVM build system isn't able to locate a "go" binary on your system. I think that's the only reason why the llvm-go target wouldn't be defined.

Thanks Andrew for your answer!

Can't wait!

The particular error you're getting looks like the LLVM build system isn't able to locate a "go" binary on your system. I think that's the only reason why the llvm-go target wouldn't be defined.

The "go" binary is in my PATH, tried both go 1.3 from the distro packages, and tried a manual install too with the latest go 1.6. Should I be configuring something to have it find the go binary?

So I'm either wrong and there's another reason, or it's just not being picked up and I don't know why. You could try passing the path to CMake explicitly, with:

cmake -DGO_EXECUTABLE=<path/to/go> ...

Cheers,

Andrew

Unfortunately it seems there's another reason :( If I set GO_EXECUTABLE to something invalid, then the failure happens at the cmake command already, but if I set it to the path of the go executable then I get the same error as if I didn't set GO_EXECUTABLE at all.

OK then, I'm sorry but I don't know. If you could provide the full command line you're passing to cmake, and the stdout, I can see if anything else jumps out. Otherwise you may have to debug the CMake configuration.

Sorry, I'm out of ideas. It's going to need some CMake spelunking.

If you're just after a working toolchain, and you're on an OS that supports them, then I've *almost* got the snap working.

Cheers,

Andrew

So I'm not sure what triggered it, but I've just now hit the same problem. It looks like there's a broken build dependency.

I got past the issue by doing "make llvm-go" first, and then "make llgo".

HTH.

Cheers,

Andrew
