Tess4j on Mac M1

[felixadl]

Hi,

i have problems getting tess4j running on my m1 mac. I'm getting the following exception:

exception in thread "pool-1-thread-1" java.lang.UnsatisfiedLinkError: dlopen(/Users/felix/Library/Caches/JNA/temp/jna3686725805253188253.tmp, 9): no suitable image found. Did find: /Users/felix/Library/Caches/JNA/temp/jna3686725805253188253.tmp: mach-o, but wrong architecture /Users/felix/Library/Caches/JNA/temp/jna3686725805253188253.tmp: mach-o, but wrong architecture

Is this a m1 problem? Does anyone can help?

Thanks in advance

It looks like there was a JNA problem with M1.

https://github.com/java-native-access/jna/issues/1313 https://github.com/java-native-access/jna/issues/1323 https://github.com/java-native-access/jna/pull/1297 https://github.com/java-native-access/jna/pull/1238

But it seems M1 support is incorporated with latest JNA versions. But if you still have issue with the latest JNA, please put in a new issue on JNA project page.

test code

@Test public void test() throws IOException, TesseractException { File img = new File(file); BufferedImage image = ImageIO.read(img); Tesseract1 ocr = new Tesseract1(); ocr.setLanguage("chi_sim"); List segmentedRegions = ocr.getSegmentedRegions(image, 0); // error here for (Rectangle rect : segmentedRegions){ System.out.println(rect); } // String s = ocr.doOCR(image); // System.out.println(s); List words = ocr.getWords(image, 1); System.out.println(words); }

ocr.getSegmentedRegions(image, 0); will raising error. but is ok in windows.
