That might be a false alarm. Tesseract supports two different build systems, one based on cmake, one based on autoconf. As far as I know all Linux distributions use the autoconf based build, so they should not be affected by the existing problems from the cmake build. The default autoconf build uses -march=native only if it is supported by the compiler and only for a single file, but not for the rest of the code. The code from that single file is not executed by default, but only if an advanced user runs Tesseract with a special command line option (-c dotproduct=native). Stefan
