The diff below fixes the pkg-config file installed by tesseract.
Before:
x1$ pkg-config --cflags tesseract
-I/usr/local/include/tesseract -I/usr/local/include/leptonica
After:
x1$ pkg-config --cflags tesseract
-I/usr/local/include -I/usr/local/include/tesseract
-I/usr/local/include/leptonica
The fix is inspired by tesseract.pc.cmake (which we do not use):
https://github.com/tesseract-ocr/tesseract/blob/3.05/tesseract.pc.cmake
(The issue is already fixed in upstream version 4.0.0)
Could you explain the problem please? I don't see anything different in
git master for this file, and don't see why -I/usr/local/include is needed
when the files are all in the subdirectory?
The tesseract headers are normally included like this:
#include <tesseract/baseapi.h>
For example in one of the opencv_contrib modules:
https://github.com/opencv/opencv_contrib/blob/master/modules/text/src/precomp.hpp
The git master version uses '-I/usr/local/include' only.
(It is not obvious if you are looking at tesseract.pc.in, the value of
@includedir@ is in fact '/usr/local/include' now).
