For curiosity, I downloaded and tried to build the tesseract OCR app that appeared in the original OCR message thread earlier. It may have worked with the 2.96 gcc on a 32 bit system, but the 4.1 gcc on my 64 bit FC6 system has fits. Looking at some of the fits it is throwing, I can see that the code simply has 64 bit problems - I don't think it will build on a 64 bit system without a lot of work. using CC="gcc -m32" and CXX="g++ -m32" env vars to force it to build 32 bit, I get a lot farther, but run into more problems with the new compiler complaining about gcc/g++ conflicting declarations. Probably not hard to fix, but tesseract definitely isn't as easy to build as ocrad or gocr.
