Could someone help?
Thanks!

Try without the patch. Maybe that change has already been applied.

Thanks, do you know how to tell brew to skip the patch?

[amitdo]

The brew formulae is for version 3.05, while the HEAD is 4.00 (alpha).

[jsl303]

Thanks, wouldn't adding --head option like "brew install tesseract --HEAD" download the latest head from the Github? I'm wondering how to tell brew to skip the patch...

[amitdo]

Dunno. I don't have a a Mac...

[Shreeshrii]

see https://github.com/Homebrew/homebrew-core/blob/master/Formula/tesseract.rb

[stweil]

@zdenop, maybe a new release 3.05.01 would help making such patches unnecessary.

[amitm02]

same here

@jsl303,

As you might already know, Homebrew's Formula can edit locally.

$ brew edit tesseract

If you want to skip the patch, comment out line 71-74, and save it.

( /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/tesseract.rb )

$ brew install tesseract --HEAD

or, wrapping patch block with 'if-end' block such like below.

My PR got merged. So, no need to edit Formula.

@jsl303, It should work with the following command.

$ brew update
$ brew install tesseract --HEAD

[stweil]

This issue can be closed. brew install tesseract --HEAD now works.

@stweil Please see the recent post at https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/tesseract-ocr/H9JmIRU2dQk/oMtSIvtHAwAJ regarding problem with install of training tools on mac os. Thanks!

[stweil]

Please see the recent post ...

I need more information because I currently cannot reproduce the build problem (building training tools works for me with MacPorts and with Homebrew).
