If you have checked out Tesseract from Subversion, you must generate the configure script. So, the steps for making Tesseract are: * ./runautoconf # ignore warnings * ./configure * make * make install Note that ./runautoconf may generate some warnings: -- quoting in some /usr/share/.../... .m4 files -- old uses of datarootdir They don't seem to hurt anything. We haven't found a good way of eliminating them yet.
