All 6 case-sensitivity shim headers in tools/linux/overlay/include/
now use #include_next instead of #include to forward to the real
MinGW system header, avoiding infinite preprocessor recursion on
Linux (Debian/WSL) where overlay/include is first in the search path.
Fixes build failures on Debian WSL (GCC 12) for all configurations.
Also update nsis7z.dll binaries built with the fixed overlay.
Aligns the zstd NSIS wrapper directory with the naming convention used by
all other bundle directories (versions/25.01-bundle, 26.00-bundle, etc.).
Changes:
- git mv versions/zstd -> versions/zstd-bundle (20 project-owned files)
- Fix UI/NSIS/StdAfx.h: use relative include ../../Bundles/Nsis7z/pluginapi.h
instead of absolute-style 7zip/Bundles/Nsis7z/pluginapi.h (portable across
both Linux and Windows builds without extra include path)
Build tool updates:
- tools/legacy/build_plugin_zstd_vs2026.py: updated project_dir path
- tools/linux/build_plugin_linux.py:
* VERSION_LAYOUT zstd: zstd -> zstd-bundle
* VERSION_EXTRA_FLAGS zstd: -Wno-sign-compare -Wno-cast-function-type
(fast-lzma2 C vendor code)
* VERSION_EXTRA_CXXFLAGS zstd: -Wno-unused-parameter (NSIS wrapper)
* EXTRA_SYS_OBJS: inject MyWindows.o for zstd (LocalFileTimeToFileTime2)
* Remove 'zip_version != zstd' exception; auto-recreate symlinks for all
bundle versions including zstd
- tools/linux/setup_bundle_symlinks.py: add VENDOR_DIR mapping so 'zstd'
points to versions/7-zip-zstd (not versions/zstd which no longer exists)
- tools/linux/overlay/makefile.gcc: add EXTRA_SYS_OBJS ?= variable so
callers can inject additional objects without modifying the file
Linux build status after this commit:
python3 build_plugin.py --7zip-version zstd -> Build completed (all 3 configs)
Replaces the per-version in-tree build files with a shared overlay that
keeps all project-owned build infrastructure outside the vendor source trees,
making it safe to use vendor directories as pristine git submodules.
Changes:
- Add tools/linux/overlay/makefile.gcc: parameterised makefile that drives
MinGW cross-compilation; VENDOR_7ZIP, DEF_FILE and NSIS_DIR are all
overridable from the command line so no files are written into the vendor
tree at build time.
- Add tools/linux/overlay/include/: case-sensitivity shim headers
(Windows.h, CommCtrl.h, MAPI.h, NTSecAPI.h, Psapi.h, ShlObj.h) that
redirect to the lowercase MinGW system headers; also adds
z7_idecl_noexcept_strip.h which resolves the noexcept-specifier mismatch
in 7-zip 25.01 NSIS UI code.
- Move Nsis7z.def from versions/26.00/…/Bundles/Nsis7z/ to overlay/ (git
rename; content unchanged).
- Delete versions/26.00/…/Bundles/Nsis7z/makefile.gcc (superseded by the
overlay).
- Rewrite tools/linux/build_plugin_linux.py to drive the overlay makefile,
support multiple 7-zip versions (25.01, 26.00, 26.01, zstd) with a
VERSION_LAYOUT table, and add NSIS_DIR auto-detection for bundle-based
builds.
- Add _linux_build/ to .gitignore.
