在Linux服务器上tesseract 3.0.2
正确安装了库:
[root@XXX as]# rpm -qa | grep ".*tess.*"
tesseract-3.02-alt1.r723
尝试运行tess4j
包装器时,遇到此异常:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'TessBaseAPICreate': /usr/lib64/libtesseract.so.3.0.2: undefined symbol: TessBaseAPICreate

(... private code ...)
在异常文件中提到:
[root@XXX as]# test -e /usr/lib64/libtesseract.so.3.0.2 && echo "Found" || echo "Not found"
Found
tess4j
代码中抛出异常的地方如下:
/**
* Initializes Tesseract engine.
*/
private void init() {
pageNum = 0;
api = TessAPI.INSTANCE;
handle = api.TessBaseAPICreate(); // ERROR HERE, line #184
api.TessBaseAPIInit2(handle, datapath, language, ocrEngineMode);
api.TessBaseAPISetPageSegMode(handle, psm);
}
我不知道如何解决它,因为所有库版本都相同,它在windows下完美运行。
答案 0 :(得分:0)
嗯,这是使用过的操作系统(“ALT Linux Centaurus 6.0”)中的软件包的特殊问题。从该操作系统下的源重建tesseract
包后,一切都变好了。
