could not generate data files

[ldez]

Even with changes from #10, I'm not able (without running steps by hand and ignoring errors) to run go-binsize-viz.

I don't know if those errors are expected (I guess not) and should be ignored in the script.
Note: I'm on linux/amd64.

$ docker run -v ./dist:/dist -p 8000:8000 knz-go-binsize-viz:temp -b /dist/binary

I think you've fixed this in #10? I'm closing this issue, feel free to reopen if relevant.

[ldez]

I cannot reopen an issue you closed.

As I said: Even with changes from #10, I'm not able to run go-binsize-viz

[knz]

Would you be ok sharing some details of the binary that causes trouble? Or is this issue the same for any binary?

[ldez]

from my memories, it's for any binaries.

[Zxilly]

Maybe you can give https://github.com/Zxilly/go-size-analyzer a try. If you find that your binary cannot be analyzed and don't mind making this binary public, please send it to me. I'm collecting weird GoLang binaries for integration testing.

I noticed that you are a maintainer of golangci-lint, here is a basic analysis for golangci-lint 1.59 linux amd64

@Zxilly thanks for the link. This is a very good piece of software!
Can it also analyze objects produced by other languages, present in the symbol table? For example, the script I produced is able to parse entries generated by C/C++ when using CGo. This is useful for programs that include external libraries.

[Zxilly]

Yes, it can load these info from dwarf.
