I finally managed to build tesseract. I have noticed that replace /usr/bin/gcc-4.9
by /usr/bin/g++-4.9 into the failing command line, make it run well. So i made the replacement in files generated by ./configure, doing grep -R "/usr/bin/gcc-4.9" . | cut -d':' -f1 | while read line; do sed -i 's/usr\/bin\/gcc-4.9/usr\/bin\/g++-4.9/g' $line; done and make then runs successfully LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make For sure, that's not an elegant way to solve it but i can't manage to get an option for ./configure to use g++ instead of gcc. If somebody knows how, i would be grateful. Hope it can help.
