The Tk compile completes when I move up to 10.9.

Thank you for this. I will keep a note of the patch in case I need to run on a 10.8 machine. In the meantime, I believe all my users are running 10.11 or later.

I try the following with TclTk 8.6.10:

export CFLAGS="-mmacosx-version-min=10.9"
make -C tcl/macosx embedded
make -C tk/macosx embedded

And as you predicted, I encounter no problems in the compilation. But I still get this same error when linking Tk.

Undefined symbols for architecture x86_64:
   "_TclIsSpaceProc", referenced from:
       _strtoul in libtclstub8.6.a(strtoul.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I get the same error when I try to build TclTk 8.7a3 with the same commands, and if I try without "embedded". If I add "-arch x86_64" to CFLAGS, the result is the same. The fact that _TclIsSpaceProc is not available is not because I compiled a 32-bit version of the routine.

I have been doing that every time, deleting the entire build directory.

Now I try building 10.7a3 with:

export CFLAGS="-mmacosx-version-min=10.15"
make -C tcl/macosx embedded
make -C tk/macosx embedded

I get the same _TclIsSpaceProc link error. According to a web search, this error was reported about six months ago in various forms, and was occuring with XCode command line tools version 12. I don't have XCode, only the CLTs. I have Clang version 12.0.0. I'm going to try the build on my previous laptop, where the compile worked a year ago.

Best, Kevan
