tesseract-3.02-r1 fails to compile when it depends on media-libs/leptonica. the tesseract build process can't locate necessary header files from the media-libs/leptonica package. i'm attaching a patch which modifies LIBLEPT_HEADERSDIR and resolves the issue on my system. Reproducible: Always Steps to Reproduce: 1. emerge =media-libs/leptonica-1.69 2. echo "app-text/tesseract jpeg png tiff" >> /etc/portage/package.use 3. emerge =tesseract-3.02-r1 4. observe failure Actual Results: emerge dies with: libtool: compile: x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/classify -I.. -O3 -DNDEBUG -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/cutil -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/ccutil -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/ccstruct -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/dict -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/image -I/var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/viewer -I/usr/local/include/liblept -I/usr/include/leptonica -O2 -march=core2 -pipe -fomit-frame-pointer -c /var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/classify/xform2d.cpp -fPIC -DPIC -o .libs/xform2d.o /var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/classify/trainingsampleset.cpp: In member function ‘void tesseract::TrainingSampleSet::DeleteOutliers(const tesseract::IntFeatureSpace&, bool)’: /var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/classify/trainingsampleset.cpp:559:68: error: too many arguments to function ‘PIX* pixaDisplayTiledInRows(PIXA*, l_int32, l_int32, l_int32)’ In file included from /usr/local/include/liblept/allheaders.h:26:0, from /var/tmp/portage/app-text/tesseract-3.02-r1/work/tesseract-3.02.02/classify/trainingsampleset.cpp:17: /usr/local/include/liblept/leptprotos.h:1075:15: note: declared here Makefile:431: recipe for target 'trainingsampleset.lo' failed make[2]: *** [trainingsampleset.lo] Error 1 Makefile:365: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 Makefile:272: recipe for target 'all' failed make: *** [all] Error 2 * ERROR: app-text/tesseract-3.02-r1::gentoo failed (compile phase): * emake failed Expected Results: >>> Installing (1 of 1) app-text/tesseract-3.02-r1 >>> Auto-cleaning packages... >>> No outdated packages were found on your system. * GNU info directory index is up-to-date. a patch to adjust LIBLEPT_HEADERSDIR resolves this issue in my environment. please consider adding it to the public app-text/tesseract ebuild if solves the same issue for others.
Created attachment 368384 [details, diff] fix leptonica include path
I can't reproduce this. Can you please try again with the new version 3.03_r1?
