Hello Nicolas, "Error in pixRead*" is error message from leptonica. Tesseract use leptonica library for opening images. That mean if leptonica can not open file tesseract can not *use *it.
So far there was ALWAYS problem with instalation of leptonica (if you got this error). As suggested in these issues - build example leptonica progs and test you image with them.
