HEAD doesn't build. Totally stalled.

How’s it going getting this patch committed?
It’s painful manually applying a fix, but then NOT committing that to master by mistake

Thanks

For some reason, you end up in the defined RTS_SSP_SYMBOLS, I believe and then the RTS wants __stack_chk symbols. Which it can’t find when linking.

Replacing

#if !defined(mingw32_HOST_OS) && !defined(DYNAMIC)

#define RTS_SSP_SYMBOLS                                \

      SymI_NeedsProto(__stack_chk_guard)               \

      SymI_NeedsProto(__stack_chk_fail)

#else

#define RTS_SSP_SYMBOLS

#endif

With just



#define RTS_SSP_SYMBOLS

Should do. I hope.

Currently only on mobile phone :-/

Cheers,
 Moritz

This was my fault. Not sure why this wasn’t caught in CI.
It’s due to the addition of the symbols here

You should be able to just comment them out. I’ll prepare a proper fix.

Cheers,

I’m getting this failure in a clean HEAD build. Any ideas?    I’m totally stalled because I can’t build GHC any more.
I’m using Windows Subsystem for Linux (WSL).
Help help!
Thanks
