Not working on windows

[lekoala]

Hey,

This looks like a wonderful tool! However I'm on windows and erlexec doesn't work. Would there be a way to make this dependancy optionnal?

erlexec runs on windows 10 here (via cygwin, I'm not using the bash shell, so this will work on any windows version).

hey @lekoala,

erlexec is required for breakpoints functionality. One solution would be to make breakpoints optional. But I'd rather try to solve the issue with erlexec. Could you copy paste your error log?

[OvermindDL1]

To be more specific, erlexec is a native binary and needs to be compiled, thus it requires a supported compiler on your system, and as long as you have that it should work fine. :-)

It 'is' possible for kagux to pre-build a windows binary and distribute it in the releases though for those that don't have C build systems installed.

@OvermindDL1, that's an interesting option. Although, if it comes to, erlexec should be doing that.

It's hard to avoid native packages though, and sooner or later you'd face a problem of building one. Unless of course it's a problem specific to erlexec. So maybe the best solution is to provide better build instructions for Windows in such cases.

Either way, @lekoala, seeing your logs would greatly help!

Not specific to erlexec at all, you need the same build system set up for bcrypt and such too. :-)

Here is the error. But I think this is to be expected since erlexec is not supported on windows. I have cygwin but I have no idea how to compile my dependencies using it.

Having the same issue as @lekoala. Googled a bit before posting this. I remember I had a similar issue compiling Bcrypt for Comeonin, but that worked out eventually with VS++. Tried the same approach here without any success.

Is there a way to use ex_debug_toolbar on Windows 10 ?

@OvermindDL1 how to build/compile erlexec under Windows via cygwin ?

[OvermindDL1]

It just works for me, though I have the full cross-compilation pipeline installed in cygwin (I have to compile ocaml as well).
