Using the ./configure script -- 16 December 2002. ================================================= The ./configure script should work compatibly with what scripts/makefile.* did, however there are some options you need to add to configure explicitly, which previously was done semi-automatically (if you didn't edit scripts/makefile.* yourself, that is) CFLAGS="-Wall -O3 -funroll-loops \ -malign-loops=2 -malign-functions=2" ./configure --prefix=/usr/include \ --with-pkgconfigdir=/usr/lib/pkgconfig --includedir=/usr/include You can alternatively specify --includedir=/usr/include, /usr/local/include, /usr/include/png12, or whatever.
