Add documentation for CGO_ENABLED to fix user issues with scc #208
Comments
Alpine images... the bane of my existence when doing anything in Go. The amount of times I have had the same issue... well its not a huge amount but enough that its etched into my brain. If you want to write the documentation into the README ill merge it in and you get the credit :) Otherwise ill add this in in a week or two. Cheers. |

* Update README.md * SLOCCount came before cloc * resolve boyter#206 * First cut at boyter#210 * Add "gohtml" and "gotxt" to the list of extensions for Go templates These are the default extensions that e.g. GoLand uses, and some other tools as well I believe. It's useful as it disambiguates between templates for html/template and text/template. * partial fix for boyter#214 * resolve after feedback * Mostly ready for boyter#211 * real fix for issue214 * few tests and typo * Resolvehttps://github.com/boyter/issues/208 * Update to remove wrong Go version mentioned boyter#220 Co-authored-by: Ben Boyter <boyter@users.noreply.github.com> Co-authored-by: AlDanial <al.danial@gmail.com> Co-authored-by: Ben Boyter <ben@boyter.org> Co-authored-by: Martin Tournoij <martin@arp242.net>

A user of scc in containers will run into issues with running the application in alpine if they do not use compiler flag
CGO_ENABLED=0
.So I was trying to run scc in a pipeline, and saw iRyanBell's implementation from your README, but I couldn't find the image; I just built my own (mjuul/scc). (I did find the image later: https://github.com/marketplace/actions/scc-docker-action -- I thought it was on docker hub).
But I ran into several issues, firstly with
go get
where it seems impossible to install v2.13.0 (see my description here: golang/go#35732) well... so I decided to compile it myself and I wrote the Dockerfile belowthen
$ docker build -t scc-image --build-arg VERSION=v2.13.0 . $ docker run -v /some/local/path/:/root/something -w /root/something scc-image
You get an error:
standard_init_linux.go:211: exec user process caused "no such file or directory"
So I noted that iRyanBell is running the i386 (32 bit) vers. succesfully (which he didn't have to anyway). And that also works. (setting
ENV GOARCH=386
).But that is very unsatisfactory; I certainly expect the program to run with the expected behavior on the same architecture.
Searching around I find: https://stackoverflow.com/questions/36279253/go-compiled-binary-wont-run-in-an-alpine-docker-container-on-ubuntu-host
and that fixes the issue.
i.e. this works:
So the documentation should mention compiler flag
CGO_ENABLED=0
for better compatibility with less dynamic linking.The text was updated successfully, but these errors were encountered:
