Sign upcmd/link: -buildmode=plugin fails on linux/arm64 #17138
Comments
Mysterious error and no time or easy machine access to investigate now, so disabling the -buildmode=plugin test on arm64. (The arm version is working as expected.)

Do you know which version of gold is installed? |
|
If I revert 569340e it fails with: do you know what's going on there? |
|
Nope, I'd have to spend some time with an arm64 machine, and I don't think I'll get to it in 1.8. I'd rather just say we haven't implemented -buildmode=plugin there yet and deal with it in 1.9. |
|
We haven't made a Go1.9 milestone yet, so I'll tag this 1.8Maybe with the expectation that it's likely going to get punted. |

With CL https://go-review.googlesource.com/c/go/+/109917, testplugin passes locally. It still fails on the builder with an internal error in gold. Seems the gold linker on the builder is rather old: On the machine where the test passes: I wonder, could we update gold on the builder, and require a newer gold for using plugin on linux/arm64? cc @bradfitz |
The init function and runtime.addmoduledata were not added when building plugin, which caused the runtime could not find the module. Testplugin is still not enabled on linux/arm64 (https://go.googlesource.com/go/+/master/src/cmd/dist/test.go#948) because the gold linker on the builder is too old, which fails with an internal error (see issue #17138). I tested locally and it passes. Fixes #24940. Updates #17138.

At least on the builder, it tickles gold the wrong way:
Odd, as the plugin mode mostly depends on linker configuration used by either c-shared or shared.
