fossil @2.22: build failure when ccache is installed

[bsdooby (Peter von Niederhäusern)]

Using Xcode 15.0.1 on macOS Sonoma (14.0) the build fails w/

Build C compiler.../usr/bin/clang -arch arm64
Checking for stdlib.h...not found

see also attached Terminal.app log file.

Terminal.app saved build log

The transcript you attached says:

Error: Compiler does not work. See config.log

Please attach that file.

[bsdooby (Peter von Niederhäusern)]

I messed up w/ my compiler env (maybe a wrong export CC=..., or export CXX=...). Ticket can be closed. Sorry about that, and thank you for your time!

[bsdooby (Peter von Niederhäusern)]

Please keep it OPEN! On the wrong system (x86). I will provide the log ASAP.
