Re: Updated: leptonica-1.74.1-1
Hi Marco, it would be great to also have cross packages of Leptonica 1.74.x for MinGW (mingw64-i868-*, mingw64-x86_64-*). They are needed to build Tesseract for Windows, for example. As far as I know, all dependencies needed for a MinGW Leptonica are already available. I'm not familiar with creating packages for Cygwin, but would be willing to help as far as I can.

No, a local build with x86_64-w64-mingw32-gcc works fine. Tested with 57.1-2, but also with recent versions of icu. A good indicator of a broken installation is a small icudata57.dll: $ ls -l /usr/*/sys-root/mingw/bin/icudata57.dll -rwxr-xr-x 1 25680896 Nov 10 2016 /usr/i686-w64-mingw32/sys-root/mingw/bin/icudata57.dll -rwxr-xr-x 115872 Nov 10 2016 /usr/x86_64-w64-mingw32/sys-root/mingw/bin/icudata57.dll The (good) file for 32 bit is much larger than the (broken) file for 64 bit.

The file command will report ASCII as long as your text does not contain any non-ASCII characters. If you add some (for example ÄÖÜ), it should report UTF-8.

It would be great to get a similar update for the mingw64-i686-icu and mingw64-x86_64-icu packages, too. Those packages are still based on icu 57, so rather out of date.

Tesseract 4.0.0 still supports the old traineddata format, but added new (and typically better) traineddata based on neural networks. There is currently no langdata available for those new traineddata. tessdata_best only contains the new traineddata. tessdata_fast also contains only new traineddata, but is faster and less accurate. tessdata still contains old traineddata for most languages and additionally new traineddata made from tessdata_best, but using integer instead of float models (which makes them faster). tessdata_best, tessdata_fast and tessdata not only contain traineddata for many languages, but also for "scripts", for example in https://github.com/tesseract-ocr/tessdata/tree/master/script. Those models support all languages using the same script, so https://github.com/tesseract-ocr/tessdata/blob/master/script/Latin.traineddata supports all languages which use Latin characters (English, French, Spanish, Italian, German, Danish, ...). A selection of those script models would be useful for Cygwin, too.

mingw64-x86_64-icu / mingw64-i686-icu 64.2
The following experimental updates are not available from Cygwin, but from my personal website https://qemu.weilnetz.de/test/cygwin/local/: mingw64-x86_64-icu 64.2 mingw64-i686-icu 64.2 I tested the binary packages using a short test program (https://github.com/tesseract-ocr/tesseract/issues/1625#issuecomment-395166694). Maybe someone else has other tests and wants to try the new packages. Both packages are currently unmaintained in Cygwin (old version 57.1, broken mingw64-x86_64-icu). See issue https://github.com/cygwinports/mingw64-x86_64-icu/issues/1 and pull request https://github.com/cygwinports/mingw64-x86_64-icu/pull/2. See also https://sourceware.org/ml/cygwin/2018-10/msg00209.html and https://cygwin.com/ml/cygwin/2018-06/msg00222.html. I need those packages to build Tesseract for Windows. I would also like to contribute packages for Leptonica (also needed for Tesseract): mingw64-x86_64-leptonica and mingw64-i686-leptonica. Building such packages is easy, but how can I can get them into the official package distribution?

[BUG] Package mingw64-x86_64-icu is broken
Both mingw64-x86_64-icu-57.1-1 and mingw64-x86_64-icu-57.1-2 are broken: This code always fails: icu::Normalizer2::getInstance(nullptr, "nfkc", UNORM2_COMPOSE, error_code); The problem was detected when comparing Tesseract for Windows executables: while the 32 bit version worked fine, the 64 bit version failed. The failure could be localized, and the mingw64-x86_64-icu package was identified to be causing it. https://github.com/tesseract-ocr/tesseract/issues/1625#issuecomment-395161152 contains details and also a short test code which can be used to reproduce the problem. The 32 bit package mingw64-i686-icu-57.1-2 works fine.
