Tk Source Code

A static wish built on Windows with gcc does not work.
When starting, I get the following error message:
    Can't find a usable tk.tcl in the following directories:
    ...

Looking at the build log, I see the following error messages regarding
creating the libtk9.0b3.zip file:

Inspection of the libtk9.0b3.zip file shows that it only contains directory tcl_library.

If building with nmake the static wish works. libtk9.0b3.zip contains directory tk_library.

Note, that on Linux file libtk9.0b3.zip contains both tcl_library and tk_library.

The remark with the zip program was good.

I used a self-compiled version of Info-ZIP, which shows the following compile options:

Compiled with mingw32 / gcc 7.2.0 for
Windows 9x / Windows NT (32-bit) on Jun 19 2021.

Zip special compilation options:
        ASM_CRC
        ASMV
        USE_EF_UT_TIME       (store Universal Time)
        NTSD_EAS             (store NT Security Descriptor)
        WIN32_OEM            (store file paths on Windows as OEM)
        LARGE_FILE_SUPPORT   (can read and write large files on file system)
        ZIP64_SUPPORT        (use Zip64 to store large files in archives)
        UNICODE_SUPPORT      (store and read UTF-8 Unicode paths)

When using the zip program supplied by MSys building a static wish works. 
The MSys zip shows the following compile options:

Compiled with gcc 13.2.0 for Unix (Cygwin) on Dec 13 2023.

Zip special compilation options:
        USE_EF_UT_TIME       (store Universal Time)
        SYMLINK_SUPPORT      (symbolic links supported)
        LARGE_FILE_SUPPORT   (can read and write large files on file system)
        ZIP64_SUPPORT        (use Zip64 to store large files in archives)
        UNICODE_SUPPORT      (store and read UTF-8 Unicode paths)
        STORE_UNIX_UIDs_GIDs (store UID/GID sizes/values using new extra field)
        UIDGID_NOT_16BIT     (old Unix 16-bit UID/GID extra field not used)
        [encryption, version 2.91 of 05 Jan 2007] (modified for Zip 3)

I did not investigate, which of the options is relevant for the zip errors.

BTW: I noticed, that the VS build does not use an external zip program, but builds the zip file using tclsh and zipfs. 
Wouldn't it be a good idea to use that way for Unix and Windows-gcc, so that no external zip program is needed for building?

After fixing that, I tried to create a static wish built on Windows with gcc. It works fine.

Could the problem be in the "zip" utility provided by 7-Zip?

At least on Github, the static build on Windows with gcc runs fine:

https://github.com/tcltk/tk/actions/runs/10521300222/job/29151723347

That doesn't tell the whole story. I'll investivate further.

One thing I know is not right: the registry and dde dll's are both statically linked and also included in the zip-file.
