Thanks for opening this issue, this shows that Ullaakut/go-curl is outdated, and after looking into it it seems that the fix I did on go-curl in my fork has been done on the original repo as well, so we can use go-curl instead of my version of it, and that should fix it.

If someone wants to pick this up, feel free to update the dependency, otherwise I'll do it when I have some time 👍

### Please help me to fix this issue @Ullaakut 🙏️🙏️🙏️

[Ullaakut]

If you want to fix it, all you need to do is replace the dependency from https://github.com/Ullaakut/go-curl to https://github.com/andelf/go-curl. That should be enough to allow you to build the docker image.

Have a good day!

[simsmith007]

I also encountered such a problem..
I feel that you are wrong, the last update of the library andelf/go-curl is 3 years ago.
It means that no changes have been made in the library to correct andelf/go-curl and the problem is somewhere else

However, we will try
Thank @Ullaakut

Thanks for your reply
But the problem still remains
The only difference is that instead of showing the error of your library Ullaakut/go-curl, it shows the error of andelf/go-curl library

I think @simsmith007 's comment is correct

Same issue here. Something to deal with libcurl version, but have no idea how to fix

[Ullaakut]

My version of go-curl is even older than that, the main branch of andelf indeed fixes the thing I tried to fix in my fork, on top of also making further changes, so either way we should replace the dependency. However indeed, it seems like there is a problem with the curl version.

Likely what would fix it then is to change the version of libcurl that is installed in the first step of the Dockerfile:

# Build stage
FROM golang:alpine AS build-env

COPY . /go/src/github.com/Ullaakut/cameradar
WORKDIR /go/src/github.com/Ullaakut/cameradar/cmd/cameradar

RUN apk update && \
    apk upgrade && \
    apk add nmap nmap-nselibs nmap-scripts \
    curl curl-dev \ # <------------------------------------------------------ Here.
    gcc \
    libc-dev \
    git \
    pkgconfig
ENV GO111MODULE=on
RUN go version
RUN go build -o cameradar

In the last stage, we specify the version of curl we want to get a very specific one, but it looks like the build stage now fails due to the curl version that matches the package manager in the golang:alpine image.

I can't look into it at the moment unfortunately.

[fransiouz]

OK @Ullaakut
It's an incompatible version requirement between go-curl and golang version.
I succeed to build with a previous version like this one :
FROM golang:1.16-alpine3.13 AS build-env

Maybe we need to find the latest version that compile correctly. But this one seems to do the job.
I tried really old ones that crash for some other reasons....

[Ullaakut]

Great that you were able to build this way 👍 At least this gives a temporary solution until we find a way to get the specific version we need of go curl while also having a recent golang image. Thank you!

[anoduck]

Don't know how anyone would discover any similarities in potential issues with the issue labeled as ambiguously as it is. It might be a good idea to change this... just saying.

I don't really have the time to troubleshoot a resolution to this issue at the moment, but the resolution to downgrade to golang:1.16-alpine3.13 does not sit well.

As for simply replacing Ullaakut with andelf, it does not work. The go version designation includes a 12 character hash at the end, and how to discover the appropriate hash I do not know.

I will have to look at this when I have more time.

[Ullaakut]

@anoduck Thanks, indeed it wasn't very clear from the title. It should be better now.

I don't have much time for open source work these days so I won't take a look at this for now unfortunately.

May I ask, why you want to build your own image instead of using a docker image? I should start including compiled binaries in releases again, my bad on this. I thought it was automated but it looks like it's not/no longer the case.

You might want to mention this in the README.md, it would save you and other users a lot of time.

Because I thought by building a new image it would provide more up-to-date stream patterns to scan with. Sadly, this was not the case.

It is no worries, github has changed a lot recently.

How so? I still maintain my repositories and can help guide people through investigating and fixing issues, I just don't have time to work on them many hours per week like I used to. That doesn't mean the repositories are abandonned (besides https://github.com/Ullaakut/RTSPAllTheThings which I archived, deprecated and suggested an alternative.)

more up-to-date stream patterns to scan with

If you have suggestions for routes or credentials to be added, feel free to contribute to the dictionaries. They were mostly compiled back in 2016 and have not been modified much, since I no longer work in the videosurveillance business and therefore no longer have access to new hardware to tinker with :)

[anoduck]

Regarding message in readme:

It would provide users a clearer understanding of what their expectations should be about the project. There is no shame in informing users up front that the project is still maintained, but not currently under development due to time constraints. By being up front about it, you may even find a group of go programmers willing to assist in development of the project. As a matter of fact, if not one of a kind, any other alternatives to this project are quite few.

Regarding patterns:

I came across a goldmine of pattern listings a few days ago attempting to discover how to access my own cheap security camera stream. When I come across it again, I will share the link.

Here is a Dockerfile that allow you to get a successful build.

@dordyan What you have just posted, will be of great help to me and my personal life. I will be sure to run this later on tonight, and see if I can tap the output of my cameras.

Sincerely, Thank You.

[anoduck]

@dordyan I had to modify your Dockerfile source code in order to get it working for me. It will be found to be more simplistic, but running it this way allowed the achievement of a successful build, where otherwise it proved unsuccessful.
