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) Index: tesseract/patches/patch-tesseract_pc_in =================================================================== RCS file: tesseract/patches/patch-tesseract_pc_in diff -N tesseract/patches/patch-tesseract_pc_in --- /dev/null 1 Jan 1970 00:00:00 -0000 +++ tesseract/patches/patch-tesseract_pc_in 7 Jan 2019 13:56:00 -0000 @@ -0,0 +1,20 @@ +$OpenBSD$ + +Index: tesseract.pc.in +--- tesseract.pc.in.orig ++++ tesseract.pc.in +@@ -4,7 +4,7 @@ bindir=@bindir@ + datarootdir = @datarootdir@ + datadir=@datadir@ + libdir=@libdir@ +-includedir=@includedir@ ++includedir=@prefix@/include + + Name: @PACKAGE_NAME@ + Description: An OCR Engine that was developed at HP Labs between 1985 and 1995... and now at Google. +@@ -13,4 +13,4 @@ Version: @VERSION@ + Requires.private: lept + Libs: -L${libdir} -ltesseract + Libs.private: -lpthread @OPENCL_LDFLAGS@ +-Cflags: -I${includedir} ++Cflags: -I${includedir} -I${includedir}/tesseract
