Unresolved path to libbacktrace, for gollvm project, on Windows 10

[advancedwebdeveloper]

I am currently experiencing an issue on Windows 10 (32bit):

I think it has to be covered within https://go.googlesource.com/gollvm/+/refs/heads/master/README.md .

Cross-referencing with #12 (comment) .

There is a stopping factor, due to lack of #19. I don't understand how to patch configs, for my testing efforts.

What I found in my CMakeError.log (hence that I have include the folder, containing cloned libbacktrace, from git repo - [https://go.googlesource.com/gollvm/#workarea](https://go.googlesource.com/gollvm/#workarea is present in my %INCLUDE% env. var.):

Determining if the backtrace exist failed with the following output:

I was thinking about adopting https://docs.microsoft.com/en-us/previous-versions/windows/desktop/legacy/bb204633(v=vs.85)?redirectedfrom=MSDN . @ianlancetaylor , any suggestions?

@ArekPiekarz , @ tehKaiN , @dbskccc - please join the discussion...

[ianlancetaylor]

I see now that this bug was filed against libbacktrace, but it seems to be a bug report against GoLLVM.

[advancedwebdeveloper]

@ianlancetaylor , so should I form another issue?

[ianlancetaylor]

Yes, it seems to me that this issue should be filed against GoLLVM (at https://golang.org/issue). I don't think there is any change that can be made to libbacktrace that would fix this, so it doesn't useful to have an issue open for libbacktrace.

[ianlancetaylor]

Closing as this is not an issue with libbacktrace.
