Python 3.12 will not have the distutils package in the standard library.
The TextFile class is particularly useful when reading [Mm]akefiles, and
recreating its functionality would be painful.
Stash a local copy of the last version of distutils.text_file.py and use
it. Do not rely on distutils being present or installed.
Two updates suggested by Paul Koning:
- Enable building multiple simulator targets using a comma-separated list,
e.g.: pdp8,pdp11,3b2
- Unconditionally clean CMake's cache each time the script is invoked.
This eliminates confusing CMake configuration messages when CMake
changes or updates, and CMake policies change.
The most recent policy change was IMPORT_LOCATION, which is now
mandatory for interface libraries. An old CMake configuration cache
doesn't reflect the import library IMPORT_LOCATION property, which
caused confusing warning messages. The cure is removing the old cache
and reconfiguring.
Move the PowerShell code from .github/workflow/cmake-builds.yml into its
own script, cmake/github_v141_xp.ps1, to keep cmake-buils.yml readable.
The script also facilitates synchronizng with the Chocolatey installer's
Wait-VSIstallerProcesses function easier (from which this this code is
derived.)
cmake-builds.yml: Check the output from Get-VSSetupInstance and
Set-VSSetupInstance. Empty (or null) output indicates that the v141_xp
install did not complete successfully. Build process will bail when that
happens.
cmake/v141_xp_install.ps1: Unused and now unnecessary script.
- find gnu-getopt when installed by homebrew in /opt
- invoke realpath only on known path components
(needed for some realpath implementation(s))
(relevant when build-flavor directory does not yet exist)
- Bump SIMH_VERSION_MINOR in CMakeLists.txt. This propagates down
through the rest of the CMake infrastructure.
- README-CMake.md, cmake/{GitHub-release.md,cmake-builder.sh}: Update
documentation. (Prettiness.)
- vcpkg.json: Update simh version-string. (Consistency.)
NOTE: Github CI/CD: There has to be an automated way to update version
numbers; researching.
- Give appveyor.yml some much needed attention. Specifically, work
around the CMake build termination when the issuing the "CMake is too
old to produce packages" warning message. There's something funky with
how Appveyor's runtime interacts with PowerShell and
warning/diagnostic output ends up terminating builds unexpectedly.
Appveyor's technical support says to write the CI/CD script using the
old DOS CMD interpreter, not PowerShell.
- Cut down the number of builds. Older Visual Studio VM images are still
in the appveyor.yml matrix, just commented out.
- dep-locate.cmake: Update dependency library version numbers to reflect
recent releases for libpng16, SDL and SDL_ttf. This affects the XP
"legacy" CMake builds on Github CI/CD, Appveyor's VS 2017 and earlier
VM images that build the minimal SIMH dependency library support
(i.e., environments where vcpkg is known not to work.)
* CMake build infrastructure
The squashed commit that builds and packages releases for the SIMH
simulator suite with CMake, version 3.14 or newer.
See README-CMake.md for documentation.
