[2.0.4]sikulixapi with java 11 on maxOS M1: problems using OCR features (Tesseract lib missing)

You have to understand the Homebrew concept for macOS M1 machines (see Home-brew docs).

In 2.0.6 (only snapshots available at the moment) I try to reflect all specific aspects of macOS M1 with respect to SikuliX

The snippets from 2.0.6 are only to give you some insights about what you would have to do in your wrapper.
Setting the jna-path correctly is the key feature.

     if (Commons.runningMac()) {
        String libPath = "/usr/local/lib";
        if (Commons.runningMacM1()) {
          libPath = "/opt/homebrew/lib";
        }
        File libTess = new File(libPath, "libtesseract.dylib");
        if (libTess.exists()) {
          Commons.jnaPathAdd(libPath); //----------------------------- add the path
        } else {
          throw new SikuliXception(String.format("OCR: validate: libtesseract.dylib not in %s", libPath));
        }
      }

// the respective method from Commons:

  public static String jnaPathAdd(String sFolder) {
    String jnaPath = System.getProperty("jna.library.path");
    if (null == jnaPath) {
      jnaPath = "";
    }
    File folder = new File(sFolder);
    if (!folder.exists()) {
      return null;
    }
    if (!jnaPath.isEmpty()) {
      jnaPath = File.pathSeparator + jnaPath;
    }
    jnaPath = folder.getAbsolutePath() + jnaPath;
    System.setProperty("jna.library.path", jnaPath);
    return jnaPath;
  }

Hi! Raiman,

Thanks for this quick reply. What I understand is that I'd better wait for 2.0.6 in order to use this machine, right?

It would be helpful if you try with the actual snapshot 2.0.6 from today.

Waiting for the final release does not change your situation:
On macOS M1 you will always need a valid Homebrew setup or a symlink for libtesseract.dylib in a folder /opt/homebrew/lib.

The actual snapshot and hence the final version needs Tesseract 5.0.1

Hi! RaiMan,

Could you please let me know where to download actual snapshot 2.0.6 and how to use it?

Thanks,
Juliana

Hi! RaiMan,

I found the 2.0.6 jar file but it is sikulixide jar file. Where can I find sikulixapi jar file so that I can run my test case written in java from eclipse?

Maven coordinates:
com.sikulix::sikulixapi::2.0.6-SNAPSHOT
from
snapshot-repo OSSRH

Hi! RaiMan,

I have a Gradle java project and in build.gradle file I put the following line
api "com.sikulix.sikulixapi:2.0.6-SNAPSHOT:2.0.6"
I got the following issue:
Could not resolve: com.sikulix.sikulixapi:2.0.6-SNAPSHOT:2.0.6

If I put
api "com.sikulix:sikulixapi:2.0.6-SNAPSHOT"
I got following issue:
Could not resolve: com.sikulix:sikulixapi:2.0.6-SNAPSHOT

I don't know how to make it work in my Gradle java project. Could you please help?

Sorry, no Gradle experience.

Correct should be:
com.sikulix:sikulixapi:2.0.6-SNAPSHOT

But I guess (as with Maven) you have to tell Gradle about the snapshot repository on OSSRH:

 <repositories>
    <repository>
      <id>OSSRH</id>
      <snapshots></snapshots>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>
  </repositories>

This is for Maven, but there surely is a similar option with Gradle.

Hi! RaiMan,

I just tried this yesterday and made it work with following build.gradle configuration. Both options are working fine: Sikuli can find images and do the click.
Option1:
*************************************
repositories {
 maven {
  url = 'https://oss.sonatype.org/content/repositories/snapshots'
 }
}
dependencies {
 api(group: 'com.sikulix', name: 'sikulixapi', version: '2.0.6-SNAPSHOT')
}
*************************************

Option2:
*************************************
repositories {
 maven {
  url = 'https://oss.sonatype.org/content/repositories/snapshots'
 }
}
dependencies {
 compile "com.sikulix:sikulixapi:2.0.6-SNAPSHOT"
}
*************************************

But I encountered a new issue: when I tried to recognize text from an image using the following code:
screen.find(new Pattern(imageFileName).similar((float) similarity).targetOffset(image.getOffsetX(),
          image.getOffsetY())).right(offset).text().trim()
I got the following error:
*************************************
org.sikuli.script.SikuliXception: OCR: validate: libtesseract.dylib not in /usr/local/lib
 at org.sikuli.script.TextRecognizer.get(TextRecognizer.java:87)
 at org.sikuli.script.OCR.readText(OCR.java:722)
 at org.sikuli.script.OCR.readText(OCR.java:707)
 at org.sikuli.script.Element.text(Element.java:1155)
*************************************
I found the actual location is "/opt/homebrew/Cellar/tesseract/5.0.1/lib/libtesseract.dylib". Could you please help?

Thanks,
Juliana

--- I found the actual location is "/opt/homebrew/Cellar/tesseract/5.0.1/lib/libtesseract.dylib".
This is we're the stuff is built and made ready.
finally there are symlinks created in /opt/homebrew/lib (brew link ...). there should be a libtesseract.dylib as symlink.
See comment #1.
