This file describes how to 6 to port the program to other OS's. 7 8 PORTING TO BSD 9 10 cpdup was developed on BSD. Most BSDs should just be able to compile 11 cpdup using the Makefile. 12 13 PORTING TO LINUX 14 15 This script should suffice when compiling under linux. For some reason 16 that I cannot fathom, linux defaults to using a 32 bit off_t. It makes 17 no sense at all to me why they would want to do this, BSDs went to 18 a 64 bit default off_t over 15 years ago. In anycase, fixing it 19 requires a few -D options. 20 21 #!/bin/csh 22 # 23 cd cpdup 24 rm -f md5.c 25 rm -f *.o 26 cc -D__unused= -D_GNU_SOURCE -D__USE_FILE_OFFSET64 -DNOMD5 \ 27 -DUSE_PTHREADS -pthread *.c -c 28 cc -D__unused= -D_GNU_SOURCE -D__USE_FILE_OFFSET64 -DNOMD5 \ 29 -DUSE_PTHREADS -pthread *.o -o ~/bin/cpdup 30 31 BACKUP SCRIPT MODIFICATIONS - you will almost certainly have to adjust 32 the do_cleanup script to extract the proper field(s) from the df output. 33 You will probably have to use 'df' instead of 'df -i', and you may have 34 to adjust the script to not check the inode fields. 35 36
