Hello, I am not Mac user, but the following output indicates that autotools are not able to use g++ for arm-64:
checking for arm-apple-darwin64-g++... no checking for arm-apple-darwin64-clang++... no Also, you try to force linking LIBS="-lz -lpng -ljpeg -ltiff", but configure claims tiffio.h (tiff header file) is not present: checking tiffio.h usability... no checking tiffio.h presence... no checking for tiffio.h... no It does not make sense to me... Also checking for arm-apple-darwin64-pkg-config... no checking for pkg-config... /usr/local/bin/pkg-config IMO you should use pkg-config within $DEVROOT/ tree, right? There is a lot of "checking for arm-apple-darwin64-xyz... no". You need to fix this first. As this is not tesseract specific, try to use some Max arm forum for solving it.
