GDB and MacOS 11.4/BigSur

[Sam Warner]

Hi,
   I need a bit of help to speed things along.

   On macOS, zsh installs an SDK, which apparently is partially needed - yet - it produces build errors.  (Attached build.log, and config.with.szh.SDKs.log)
   Meanwhile, if I temporarily remove the SDK of zsh, then ‘./configure’ fails. (Attached config.without.szh.SDKs.log)

  I was about to start setting up LD and INCLUDE environment variables, yet I think this is already handled by “./configure"

   I’m a bit lost.  Any suggestions?

Sam
