Trying to build the minizip utility from contrib/minizip after an autoreconf -f: libtool: link: gcc -g -O2 -o minizip minizip.o minizip.o: In function `getFileCrc': /tmp/zlib/contrib/minizip/minizip.c:211: undefined reference to `crc32' minizip.o: In function `main': /tmp/zlib/contrib/minizip/minizip.c:378: undefined reference to `zipOpen64' /tmp/zlib/contrib/minizip/minizip.c:451: undefined reference to `zipOpenNewFileInZip3_64' /tmp/zlib/contrib/minizip/minizip.c:502: undefined reference to `zipCloseFileInZip' /tmp/zlib/contrib/minizip/minizip.c:509: undefined reference to `zipClose' /tmp/zlib/contrib/minizip/minizip.c:485: undefined reference to `zipWriteInFileInZip' collect2: error: ld returned 1 exit status The cause: contrib/minizip/Makefile.am does not specify that minizip needs to be linked to libminizip. With some linkers (e.g., GNU binutils without --copy-dt-needed-entries), an indirect dependency cannot be used to resolve symbols, so link to libz for crc32(), too.
