  issue 197 ([FixPatch] buildhtml produces no output) commented on by tfmorris   -   Although this patch has been flagged as accepted, it doesn't appear to have been applied to the repository, at least as of rev fb0eb45fe413. Without it, ocropus generates text files with 6 character names and looks for them with 4 character names, thus generating an empty html file.

  issue 228 ([error] CHECK ocr-line/glclass.cc:1743 Training incomplete f...) commented on by tfmorris   -   That check was added in rev 5d23c19169 on Nov. 8, by gv. I haven't dug in to whether the check is valid and is indicating a real underlying problem, but commenting it out allows things to run and produce results. I haven't done any real evaluation yet, but it does correctly recognize the simple.png test file.

I've tried the aepalea-suggested changes in xml_unescape and they make no difference for me.

  issue 228 ([error] CHECK ocr-line/glclass.cc:1743 Training incomplete f...) commented on by aepalea   -   Decided to try the tagged release 0.4.3. It didn't compile properly with g++ (Ubuntu 4.4.1-4ubuntu8) 4.4.1 Constness violation in xml_unescape. Fixed by changing p to const char* and adding the const_cast<>. Now the example works as documented. void xml_unescape(nustring &dest, const char *src) { CHECK_ARG(src); dest.clear(); const char *begin = src; const char *p; while((p = strchr(begin, '&'))) { append_to_nustring(dest, begin, p - begin); begin = append_XML_entity(dest, const_cast<char *>(p)); CHECK_CONDITION(begin); } append_to_nustring(dest, begin); }

  issue 226 (RemoveImageRegions doesn't compile (with HAVE_LEPTONICA)) reported by mika.raento   -   It inherits (and implements) ICleanupBinary and ICleanupGray. This makes it inherit const char* interface() through both and results in a "no unique final overrider". I haven't read enough of the code to understand the contract for interface() to know how to fix this. It also doesn't implement cleanup_gray() though ICleanupGray declares it as a pure virtual. If I understand the code correctly this can be implemented by just calling cleanup().

Now I'm getting this error: {{{ FATAL: /usr/local/share/ocropus/models/default.model: failed to load (/usr/local/share/ocropus/models/default.model: failed to load (/usr/local/s) }}} /usr/local/share/ocropus doesn't exist. So I tried creating it and symlinking "models" within it: [0 amanda@brahms ~]$ sudo ln -s /srv/ocropus/build/ocropus/data/models /usr/local/share/ocropus/models Now I can't find "default.fst": FATAL: /usr/local/share/ocropus/models/default.fst: failed to load (/usr/local/share/ocropus/models/default.fst: cannot open file for reading) [0 amanda@brahms ~]$ locate default.fst /srv/ocropus/build/ocropus/.hg/store/data/data/models/default.fst.gz.d /srv/ocropus/build/ocropus/.hg/store/data/data/models/default.fst.gz.i /srv/ocropus/build/ocropus/data/models/default.fst.gz So I gunzip default.fst.gz. And ... `FATAL: /home/amanda/Documents/DocumentCloud/CalSEI/SEI-A.pdf: file has an unknown extension` I can't OCRopus a PDF?

  DevInstall Wiki page commented on by moraving   -   Here's what I did on 9.04 ... * Followed the instructions above and then went back to http://code.google.com/p/ocropus/ and tried running `hg update -r ocropus-0.4.3` in both `iulib` and `ocropus` I don't really know how scons works, or whether I'm supposed to run `scons` and `sudo scons install` every time I update. The error I'm getting is {{{ error while loading shared libraries: libiulib.so: cannot open shared object file: No such file or directory }}} In fact, it does exist: {{{ [0 amanda@brahms build]$ locate libiulib.so /srv/ocropus/build/iulib/libiulib.so /usr/local/lib/libiulib.so }}} So any idea what gives?

  DevInstall Wiki page commented on by falkenhagen   -   I cannot seem to get ocropus to output the result of OCR... I get the following for the quick test: {{{ $ ocropus page data/testimages/simple.png [info] got 240 bboxes [info] all = 0 }}} and I cannot find the OCR result. Is this the expected output, and is the OCR result somewhere?
