End users no longer have to install Tesseract separately for OCR on
scanned PDFs — the engine ships inside the installer, portable .zip,
and AppImage for all three platforms.
Per-platform fetch in build/make_release.py (run before PyInstaller):
- Windows: download UB-Mannheim installer 5.5.0.20241111, extract
with 7-Zip, copy tesseract.exe + required DLLs into the staging dir.
- macOS: ``brew install tesseract``, copy binary + every Homebrew-
prefixed dylib resolved via otool -L (recurse one level for
transitive deps), then install_name_tool rewrites IDs / load paths
to @loader_path/... so the bundle is relocatable.
- Linux: ``apt-get install tesseract-ocr libtesseract5``, copy binary
+ every non-system .so from ldd output, patchelf --set-rpath '$ORIGIN'.
Wire-up:
- build/datatools.spec reads DATATOOLS_TESS_STAGING env var (set by
make_release) and adds the staging dir + tessdata + the
LICENSE_TESSERACT.txt Apache 2.0 attribution to PyInstaller datas
so they land at <bundle>/tesseract/{tesseract[.exe],tessdata/}
and the license sits at the bundle root. Soft-warns when staging
is empty so dev spec runs still complete.
- English tessdata pulled by fetch_tessdata() from
tesseract-ocr/tessdata_best (eng.traineddata, ~16 MB). Cached at
build/vendor/tessdata/.
- .github/workflows/build.yml: actions/cache@v4 step keyed on
``tesseract-${runner.os}-5.5.0-tessdata_best-v1`` caches the
staging dir and the vendored tessdata across runs; apt installs
patchelf on the Linux runner; PyInstaller step now receives the
DATATOOLS_TESS_STAGING env var.
- .gitignore: build/_tesseract/ and the .traineddata blob.
- TESSERACT_SKIP_FETCH=1 honored for offline / manual stages.
- Installer / .dmg / .zip / AppImage scripts: one-line comments
confirming Tesseract rides along automatically via PyInstaller's
datas (no extra packaging steps required in those scripts).
Bundle-size delta: ~50-70 MB on disk per platform, ~25-40 MB post-
compression. Net installer size ~250-300 MB (was ~120 MB) — accepted
tradeoff for zero end-user OCR setup.
Reversal of the prior "don't bundle Tesseract" decision (option A).

|
# bash build/macos/build_dmg.sh <version>
|
|
#
|
|
# Run after ``pyinstaller build/datatools.spec --clean --noconfirm``
|
|
# has produced ``dist/DataTools.app``. The output DMG goes to

# Code signing + notarization happen separately (see build/README.md
|
|
# "Signing"). This script only handles the packaging step.

|
|
# Tesseract bundling: no-op here. The .app already contains
|
|
# Contents/Resources/tesseract/{tesseract, *.dylib, tessdata/} thanks
|
|
# to PyInstaller's BUNDLE() carrying the spec's datas through. This
|
|
# script just wraps the finished .app — no extra steps for OCR.
