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 On Tue, 14 Jul 2020 at 7:06 PM, Simon Peyton Jones <simonpj@microsoft.com> wrote:

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
