I have just been installing ddrescue on MacOS on M1 Mac.
The documentation says: /5. Type 'make install' to install the programs and any data files and// // documentation.// // // Or type 'make install-compress', which additionally compresses the// // info manual and the man pages after installation.// // (Installing compressed docs may become the default in the future)./ On recent MacOS, doing this gives: MacMiniM1 ddrescue-1.27 % make install if [ ! -d "/usr/local/bin" ] ; then install -d -m 755 "/usr/local/bin" ; fi install -m 755 ./ddrescue "/usr/local/bin/ddrescue" install: /usr/local/bin/ddrescue: Permission denied make: *** [install-bin] Error 71 Apple has become a bit paranoid about access to various directories in the last few years. sudo overcomes this problem, ie, sudo make install There may be other solutions.
