[stweil]

@Shreeshrii, I just tested it myself. The reported linker error is fixed. But there are lots of similar linker errors.

[stweil]

We got the same result. :-)

[Shreeshrii]

I will wait for your fix. :-)

[zdenop]

I think tests should be run with standard (default) setup (that does not modified API).
And IMO disabling legacy engine is bad idea: it has better result in some cases e.g. OSD see #2062

[stweil]

Pull request #2441 fixes the build make check without legacy engine. It does not fix the unittest. Some fail and need more care.

[Shreeshrii]

@stweil Thanks. make check is building ok now. However as mentioned above by you, some unittests are failing.

Should I leave this issue open till that is fixed?

[stweil]

Yes, please leave it open.

[Shreeshrii]

Please see https://groups.google.com/forum/?utm_medium=email&utm_source=footer#!msg/tesseract-ocr/9HSpp7Ysduw/r8FPCHhBFAAJ as it might be related to this issue.

[amitdo]

I recently made a few changes related to this issue.

Does someone want to test this and see if the issue of failing tests when the legacy engine is disabled still occurs?

[Shreeshrii]

See #3226 for currently failing tests with --disable-legacy
