I will get such error when using Pix the first time java.lang.UnsatisfiedLinkError: Error looking up function 'pixaConvertTo8Color': /usr/local/lib/liblept.so.5: undefined symbol: pixaConvertTo8Color com.sun.jna.Function.<init>(Function.java:208) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:536) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:513) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:499) com.sun.jna.Native.register(Native.java:1509) com.sun.jna.Native.register(Native.java:1396)...

Lept4j is 1.6.0 and Leptonical is 1.74.4. Tesseract can work well only meeth this error when using Pix with leptonical.

I am using tess4j in Linux to use OCR in java and involved lept4j. When using code as below Pix pix = Leptonica1.pixRead(image.getPath()); will get the error as java.lang.UnsatisfiedLinkError: Error looking up function 'pixaConvertTo8Color': /usr/local/lib/liblept.so.5: undefined symbol: pixaConvertTo8Color com.sun.jna.Function.<init>(Function.java:208) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:536) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:513) com.sun.jna.NativeLibrary.getFunction(NativeLibrary.java:499)...

Got resolved by specifying LD_LIBRARY_PATH. Thanks.

BTW tesseract can work well in command line.

I am using tess4j 4.0.0 with tesseract 4. Got the error as java.lang.NoClassDefFoundError: Could not initialize class net.sourceforge.tess4j.TessAPI1 for the code this.tessBaseAPI = TessAPI1.TessBaseAPICreate(); Tesseract is installed well. Anything special i have to check for this? Thanks.

Included all the dependencies but still got the same error. It only happend in AWS AMI and not happend in MAC and Ubuntu
