CompilationError with tesseract-ocr 3.04 #50

atuyosi · 2015-08-27T17:35:44Z

I'm getting a CompilationError when 'require tesseract-ocr'.

CompilationError: compile error: see logs at /tmp/.ffi-inline-1000/00ac1de4050b632b230475bd71c0dc3a7de45a89.log
from /usr/lib/ruby/gems/2.2.0/gems/ffi-inline-0.0.4.3/lib/ffi/inline/compilers/gcc.rb:35:in `compile'

full trace is here, and ffi-inline's error log

Is the latest tesseract-ocr( 3.04) supported?
or any API changed?

There are similar problem bellow.

Thanks in Advance.

The text was updated successfully, but these errors were encountered:

Yeah, it looks like they changed quite some stuff, especially regarding output.

It will take some time, in the meantime you can use downgrade or downgrader from the AUR.

atuyosi · 2015-08-27T18:05:11Z

OK. Thanks.

McRip · 2015-08-28T12:17:17Z

👍

acrogenesis · 2015-09-02T22:16:29Z

do you know which stuff changed? perhaps I can help

meh · 2015-09-02T22:51:00Z

@acrogenesis it looks like they added a TessRenderResult class which is used in place of STRING for ProcessPages.

cxhartmann · 2015-10-20T20:41:13Z

The changes in the following fork fixed the problem for me with the Tesseract 3.04 baseline: ortutay@74a4042

This also applies to MacOS and Tesseract installed via Homebrew which now defaults to 3.04.

@meh can you share your thoughts on this change

meh · 2015-10-20T21:43:22Z

@cxhartmann the problem is the Ruby side of things expect process_page to store its value in a STRING*, which is not the case anymore.

With that change it's going to compile, but it's going to segfault or worse as soon as you use anything related to process_page.

cxhartmann · 2015-10-20T23:58:43Z

@meh Ah I see. So there is more to it. Bummer, but only if you use process_page? I'd have to guess it might be more than just that.

For now I'm reverting to Tesseract v 3.02 and that seems to be working. Now that homebrew points to 3.04 (as of Sept), I went ahead and just brew uninstalled and sucked down the old homebrew formula to do the 3.02 build for me and that seems to be working fine. https://github.com/Homebrew/homebrew/blob/master/Library/Formula/tesseract.rb (check a few revisions back)

meh · 2015-10-21T00:06:07Z

@cxhartmann yes, and the biggest problem is getting this gem to work with both pre and post 3.04.

tpendragon · 2016-01-25T22:15:58Z

@meh Any word on supporting 3.04?

meh · 2016-01-25T22:50:46Z

Haven't had the time to work on it unfortunately, it's on my endless TODO list

alexhanh · 2016-07-13T08:49:57Z

I just wanted to use easy_captcha_solver ruby gem that requires tesseract-ocr ruby gem. It installed without error but when I try to use it I see that tesseract-ocr is failing to compile.

It's also not clear if tesseract (distribution package for exemple) is needed for the tesseract-ocr ruby gem ?

Mahesh8 · 2017-08-28T10:21:20Z

I tried using this

brew install https://raw.githubusercontent.com/Homebrew/homebrew/8ba134eda537d2cee7daa7ebdd9f728389d9c53e/Library/Formula/tesseract.rb

to install a downgraded version of Tesseract on my Mac. However, I get the following error

Error: Calling Resource#sha1 is disabled!
Use Resource#sha256 instead.
/Users/maheshmesta/Library/Caches/Homebrew/Formula/tesseract.rb:123:in `block (2 levels) in class:Tesseract'

How do I rectify this issue?

tjaklitsch · 2017-09-04T12:45:30Z

@Mahesh8 Tried the same, getting nowhere so far

enriquebrgn · 2017-09-04T17:27:41Z

After fiddling around for a while I came up with a solution. I've modified the file to use sha256 and also update the broken links in the file.

First, download the following file and save it as Tesseract.rb: https://gist.github.com/arcticbarra/631bf0fee3c7eacc2c8b1e7b70e3e85d
Uninstall current version of tesseract with brew uninstall tesseract
cd to the directory and then run brew install Tesseract.rb

jpperlm · 2017-12-20T04:26:39Z

This fix doesn't seem to be working anymore - is there a current workaround?

zachfeldman · 2018-02-25T03:31:58Z

It doesn't work because it has some outdated homebrew terminology. I commented out a few lines and was able to install Tesseract 3.0.2 and make this lib work!

For anyone looking for which lines to comment out:
https://gist.github.com/zachfeldman/bfc7bac4543d466e9c096d585e373fbf

jasonfb · 2021-10-15T11:47:13Z

thank you @zachfeldman -- with the file above I'm getting

Error: Tesseract: Calling `sha256 "digest" => :tag` in a bottle block is disabled! Use `brew style --fix` on the formula to update the style or use `sha256 tag: "digest"` instead.

I wonder where this is coming from because I don't see any such syntax in your Tesseract.rb (from gist) above

Hyperadministrator · 2023-01-21T15:28:42Z

There are 2 weird download links in the script mentioned in the solution here #50 (comment) which I don't trust. My main concern is with the GoogleDrive link (which is now also broken as well). Therefore issue still present for me.
