What operating system and processor architecture are you using (`go env`)?

My host is ubuntu 1404.

What did you do?

I use Yocto-project to build consul.
It works with go-1.11 but compile failed with go-1.12.
I found that If I remove -linkshared argument, it also works with go-1.12

The error info is as following:
# github.com/hashicorp/consul/connect/certgen
type..eUfRrckI: missing section for relocation target type..FEeY9FdU
type..eUfRrckI: reloc 8 (R_CALL) to non-elf symbol type..FEeY9FdU (outer=type..FEeY9FdU) 49 (SABIALIAS)
# github.com/hashicorp/consul
type..eUfRrckI: missing section for relocation target type..FEeY9FdU
type..K6Uq9NPs: missing section for relocation target type..tBBUxeDj

The above prompts are from /usr/lib/go-1.12/src/cmd/link/internal/ld/data.go

Attachment is my bash script which contains go install command.
It failed at line:130(-linkshared):
run.do_compile.txt

Could someone give me some direction to fix or locate the issue? Maybe the issue is related with my environment.
Thanks.

How to reproduce.

We should build a Yocto Project.

~$: git clone git://git.yoctoproject.org/poky
~$: cd poky/
~/poky: git clone git://git.yoctoproject.org/meta-cloud-services
~/poky: git clone git://git.yoctoproject.org/meta-virtualization
~/poky: git clone git://git.openembedded.org/meta-openembedded
~/poky: source ../oe-init-build-env
~/poky/build: vi conf/bblayers.conf
Add six paths to BBLAYERS:
BBLAYERS ?= " \
/ala-lpggp22/hsong/poky-qcon/meta
/ala-lpggp22/hsong/poky-qcon/meta-poky

/ala-lpggp22/hsong/poky-qcon/meta-openembedded/meta-filesystems
/ala-lpggp22/hsong/poky-qcon/meta-openembedded/meta-oe
"
bitbake consul
This command will build consul and its dependencies.
Then the issue will prompt when doing do_compile of consul.

If you have any question about Yocto Project with please contact me.

Please cut and paste text. Please do not post screenshots, as they are read and harder to work with. Thanks.

Can you tell us exactly how to recreate the problem? Thanks.

I encountered this issue when I debugged yunabe/lgo#82.
I created a minimal example to reproduce this issue with go1.12.1.

https://github.com/yunabe/gobug30768

How to reproduce the issue

go get -d github.com/yunabe/gobug30768
(cd /tmp && rm pkg -rf && go install -buildmode=shared -linkshared -pkgdir pkg std && go build -linkshared -pkgdir pkg github.com/yunabe/gobug30768 && ldd gobug30768)

Expected

go build outputs a binary and ldd shows information like:

...
libstd.so => /tmp/pkg/libstd.so
...

Actual

go build fails with the following error message:

# github.com/yunabe/gobug30768
type..Fm7EsLz5: missing section for relocation target type..FEeY9FdU
type..Fm7EsLz5: reloc 8 (R_CALL) to non-elf symbol type..FEeY9FdU (outer=type..FEeY9FdU) 49 (SABIALIAS)

@andybons This appears to be a regression -- see https://github.com/yunabe/lgo#disclaimer. Would it make sense to add a 'Soon' label? (Looking at it, that label says it's the one for regressions.)

I'm one of the people hitting this bug -- Jupyter Notebook is stuck on Go 1.9 or so due to multiple regressions including this one. Jupyter's not a huge user base, but it does seem to exercise things pretty well.

…rnal ABI These functions are compiler generated, and as such are only available in the internal ABI. Doing this avoids generating an alias symbol. Doing that avoids confusion between unmangled and mangled type symbols.
