This will probably take a couple of hops again. Let's hope for the best...

Error on line 8: expecting target : dependencies

Looks like some patching error? :/

Looks like some patching error? :/

Yep -> https://github.com/braddr/at-client/blob/master/src/diff-dmd-win64.diff
We should really get rid of these :/

[wilzbach]

This is blocked on braddr/at-client#8 due to auto-tester's patching :/

[wilzbach]

This is now failing with:

..\generated\windows\release\32\dmd.obj(dmd) 
 Error 42: Symbol Undefined ?out_config_debug@@YAX_N000000@Z
Error: linker exited with status 1

Has anyone seen this before?

Unless you already figured this out, out_config_debug is defined in dmd/backend/backconfig.c, only when the C preprocessor macro DEBUG is defined. It's called from backend_init in a debug statement in dmd/dmsc.d.

Looks like this one was "healed" by the DMD backend conversion to D (:

[wilzbach]

Debug builds fail also on Linux at the moment: #7528

[wilzbach]

CC @thewilsonator this is ready to go and passing on the CIs.

Auto-merge toggled on

[thewilsonator]

Auto-merge toggled off

[thewilsonator]

Its failing agin now.

[rainers]

removing auto-merge because the unittest is failing. Running dmd without args is considered an error, something like dmd --version should be used instead.

This could be closed beceause #10612 enabled unittesting on windows

Thanks!
