Alongside the Tcl/Tk 8.6.9 releases just announced, you will find one
additional file, tk8.6.9.1-src.tar.gz . This is an errata release
fixing a critical error on the Mac OSX 10.14 Mojave platform only.
If you are building Tk for any other platform, there is no need to
upgrade to the errata release. If you do upgrade to it anyway, you will
see no difference, so it will be harmless through wasted effort, as the
details below will explain.

When unpacked, the errata archive differs from the tk8.6.9-src.tar.gz
contents in only three lines of the file
tk8.6.9/macosx/tkMacOSXWindowEvent.c
which is a file compiled only for Mac OSX builds of Tk. The lines are
written to have effect only on Mojave. Every other byte of the source
code distribution is unchanged.

Big thanks to Marc Culler for completing this new port of Tk to the
Mojave platform, and big apologies from me for this botch in the
release.

Happy Tcling with Tk!

I am having considerable trouble building Tcl 8.6.9 under Msys2 using the x86_64-w64-mingw GCC toolchain (installed today via the 'pacman' package manager). Much of the trouble is due to some names that don't match what's provided by the toolchain, and (so far) that Thread won't build because configure does not come up with a name for "SHLIB_LD", which causes the shared library build for that package to fail.

After a few hours of trying, I wiped out my MSYS2 installation and started over. The hard-coded (for a mingw build) tool names that are wrong are:
x86_64-w64-mingw32-ar (package has "x86_64-w64-mingw32-gcc-ar.exe")
x86_64-w64-mingw32-ranlib (package has "x86_64-w64-mingw32-gcc-ranlib.exe")
x86_64-w64-mingw32-windres (package has "windres.exe")

The lack of the ".exe" extension is not a problem. I created small shell-scripts of the name used by the generated Makefile that passes control to the correct files, but the failure of a definition for the "SHLIB_LD" symbol in the file "tcl8.6.9/win/pkgs/thread2.8.4/Makefile" has left me scratching my head. Without a definition, I get:

rm -f thread2.8.4
o thread2.8.4 threadNs.o threadCmd.o threadSvCmd.o threadSpCmd.o threadPoolCmd.o psGdbm.o psLmdb.o threadSvListCmd.o threadSvKeylistCmd.o tclXkeylist.o threadWin.o "/c/Projects/tcl-build/tcl8.6.9/win/libtclstub86.a" -static-libgcc
/bin/sh: o: command not found
make[1]: *** [Makefile:271: thread2.8.4] Error 1
make[1]: Leaving directory '/c/Projects/tcl-build/tcl8.6.9/win/pkgs/thread2.8.4'

I know that this may be user error, but I've found nothing anywhere that has told me much. The README points me to "Msys + MinGW-w64 [http://mingw-w64.sourceforge.net/]" which is what I have (well, I have Msys2, which is what the MinGW-w64 website points to).

Does anyone have any suggestions?

This is what I use:

export CFLAGS=-m64
export PKG_CFLAGS=-m64
cd win
make distclean
test -f config.cache && rm -f config.cache
./configure --enable-64bit --with-encoding=utf-8 --prefix=$INSTLOC
make clean
make install
