The author has read about creative hackers using a VM containing a real OS to circumvent the Apple restriction. +Building +======== +This package is designed to be built with the usual: + "./configure ; make ; make install" +sequence. In some situations that may need to be prefixed by a call to +the "./autogen.sh" script which invokes autoconf and automake. That in turn +may require packages containing those utilities to be installed. The +libtool utility is also required. Naturally a C compiler is required +and due to the vagaries of libtool a C++ compiler also. + +The C code in this package is written for portability rather than speed. +It assumes a level of C99 compliance and favours POSIX system and library +calls over OS specific calls. + +More generic build information can be found in the INSTALL file. + +In Linux there are package build files for "rpm" based and for "deb" based +systems. The 'sg3_utils.spec' file in the main directory can be used like +this: 'rpmbuild -ba sg3_utils.spec' in a rpmbuild tree SPECS directory. +The 'build_debian.sh' script should build several "deb" packages and place +them in the parent directory. In debian based systems doing +a 'apt-get install build-essential' is one way to get most of build +environment needed if it has not already been loaded.
