Tcl Source Code

Ultimately though I think it would be more maintainable to combine the build systems.

I looked at e.g. https://sourceforge.net/p/tcl/mailman/message/59319969/ and https://core.tcl-lang.org/tcl/tktview/3432902fffffffffffffffffffffffffffffffff and if there is interest in a CMake or Meson build system I think that would be prudent too.

I would be willing to contribute a unified build system in either autoconf or one of those two if there is interest in this.

There is also an issue that when Cygwin DLLs are installed in bindir, tclConfig.sh still says -L<libdir>.

This is a great example of how split build systems don't really help that much --- Cygwin is Unix-like enough that it should use the Unix build system, but still has some Windows oddities. This means that the Unix build system cannot free itself of those Windows concerns, as one might have hoped the split would accomplish.

Thanks it did! you can see https://github.com/NixOS/nixpkgs/pull/553016 for the result. (https://github.com/NixOS/nixpkgs/pull/556835 will clean it up but at the moment I post this GitHub is rendering the diff all wrong.)

There is also an issue that when Cygwin DLLs are installed in bindir, tclConfig.sh still says -L<libdir>.

The normal way on Cygwin is to have a cygtcl9.x.dll in /usr/bin and a libtcl9.x.dll.a file in /usr/lib. So -L<libdir> is correct here. It works for me.

Oh yes, that makes sense. The thing I had shuffling stuff libs/dirs around ended up being totally unneeded too, so confirmed empirically on our end also!

Ah! https://core.tcl-lang.org/tcl/tktview/17960b80db is the fix I needed -- I did a build with TCL 8.6 and that was the one missing it. I can just backport it in my distro.
