8 years ago Hi @JeanAzzopardi,
Does this file exist?
/Users/jeaz/Testing/PersonalTests/openalpr-ios/output/leptonica.framework/leptonica
Also, is there anything in this folder?

8 years ago Hi,
Yes, the leptonica file exists:

Tesseract is complaining that the leptonica library is not there, but it seems to be. Do you mind attaching this log file?

8 years ago Ah, I found the issue, tesseract's configure script expects leptonica's location to be passed through an environment variable.
For now I've done a quick hack:
env = {
'SDKROOT' => sdk_root,
'CXX' => CXX,
'CC' => CC,
'LD' => LD,
'AS' => AS,
'AR' => AR,
'NM' => NM,
'RANLIB' => RANLIB,
'LDFLAGS' => ldflags,
'CFLAGS' => cflags,
'CPPFLAGS' => cflags,
'CXXFLAGS' => cflags,
'PATH' => "#{XCODETOOLCHAIN}/usr/bin:#{ENV['PATH']}",
'LIBLEPT_HEADERSDIR' => '/Users/jeanazzopardi/software/openalpr-ios/output/leptonica.framework/Headers'
}in automake.rb Using this method, tesseract is compiling as we speak.

8 years ago Hi @JeanAzzopardi,
Usage of LIBLEPT_HEADERSDIR should not be required, as the ruby script passes a separate include directive in the CFLAGS, CPPFLAGS and CXXFLAGS with this same path. Here's the relevant part from the build.log line you included in the original comment:
-I/Users/jeaz/Testing/PersonalTests/openalpr-ios/output/leptonica.framework/Headers
I also noticed that the most recent comment above, the path is now /Users/jeanazzopardi/.... instead of /Users/jeaz. Could that maybe have contributed to the script not finding leptonica previously?

8 years ago @twelve17 I'm on a different computer - that's why I have a different username - however, I had the same issue on this one.
I realize that you are passing it as an include directive, however the configure script explicitly seems to want it as an environment variable. Perhaps it worked for you because you had it installed system wide?

8 years ago @JeanAzzopardi , you were absolutely correct! I had leptonica installed via homebrew on my system. I've pushed a code change to include LIBLEPT_HEADERSDIR. Give it a shot and see if it works for you. Thanks!

8 years ago @twelve17 This worked perfectly, thanks! Got the sample app running in the simulator as well!
I also created a pull request with some additional gems that were required by the build script.
Also, many thanks for the revamp :)

8 years ago Hi @JeanAzzopardi - thanks for the PR and for testing the fix. Very glad the sample app worked too!

8 years ago @twelve17 No problem, this is very useful for a pet project of mine :) I wonder if it's possible to get this in a cocoapod or carthage though, any ideas how this could ever be done?
twelve17
commented
8 years ago @JeanAzzopardi I'm sure it's possible. :) I'm not familiar with building either. I believe opencv 3.x needs to get into cocoapods before it can be done. As far as Carthage is concerned, I am building alpr via xcodebuild so I suppose it should be doable there too.
Another challenge will be how to build a dynamic framework, which I ran into a lot of headaches trying to do. Either the linker couldn't find the secondary alpr libraries, or when it did, it couldn't load them for unexplained reasons (the errors were vague).

Something went wrong, bailing out!@forecodema - do you have a system leptonica lib installed elsewhere?

8 years ago I think there is no other leptonica on my system:
michal$ brew unlink leptonica
Error: No such keg: /usr/local/Cellar/leptonica
michal$ brew unlink tesseract
Error: No such keg: /usr/local/Cellar/tesseractStrange - reinstalling autoconf and automake as follows did the trick.
$brew remove autoconf
$brew remove automake
$brew cleanup && brew prune
$brew install automakeI got nothin'. :)
Hi, thanks for updating the repository! I've tried to run the build script, however I have the following issue:
This is the last line from the build log:
Now, I've checked this folder:
/Users/jeaz/Testing/PersonalTests/openalpr-ios/output/leptonica.framework/Headersand inside there is a folder calledleptonicawith the following files:Any idea what it could be please?
