Re: GDB and MacOS 11.4/BigSur

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
