Hi thank you for submitting this bug. The example in the readme is a bit behind the _examples folder, I shall look at that, in the mean time you might be able to solve this bug by running one from the _examples folder

EldoranDev commented 5 years ago

Running demo.go from _example results in the same error.

fatal error: unexpected signal during runtime execution
[signal SIGSEGV: segmentation violation code=0x1 addr=0x17 pc=0x411326]

looks like its related to some channel stuff:

goroutine 5 [syscall]:

os/signal.loop()

@EldoranDev Sorry, I'm late. Can you let me know Go's version ?

EldoranDev commented 5 years ago

I used the following image:

golang:latest / golang:1.12.8

So it should be go version 1.12.8

skanehira commented 5 years ago

@EldoranDev Thank you :) How did you run _example/demo.go ? like this?

cd _example
GO111MODULE=on go run demo.go
EldoranDev commented 5 years ago 
FROM golang:latest as build

ADD . /go/src/cui-test
WORKDIR /go/src/cui-test
RUN go get -d ./...
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix "static" -o main .

FROM scratch as prod

COPY --from=build /go/src/cui-test/main /bin/main

CMD ["/bin/main"]
skanehira commented 5 years ago

It did not reproduce on the Mac. I think it may be a problem with the OS. I'll continue to investigate.

procedure

$ cd _example
$ make Dockerfile
$ docker build -t gocui-sample .
$ docker run --rm -it gocui-sample

Dockerfile

FROM golang:1.12.8 as build

ADD ./hello.go /go/src/cui-test/
WORKDIR /go/src/cui-test
RUN go get -d ./...
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix "static" -o main .

FROM scratch as prod

COPY --from=build /go/src/cui-test/main /bin/main

CMD ["/bin/main"]

@EldoranDev does the same panic happen with other samples?

EldoranDev commented 5 years ago

Okay, I do not know why. But I can not reproduce this as well.

So sorry for wasting your time, seems like a can't reproduce issue to me.

glvr182 commented 5 years ago

No problem, thanks for the update!
