Hi, when cross compiling systemd-44 for my arm target I run into compile problem in src/util.c src/util.c: In function 'parse_bytes': src/util.c:3158:17: error: overflow in implicit constant conversion [-Werror=overflow] src/util.c:3159:17: error: overflow in implicit constant conversion [-Werror=overflow] src/util.c:3160:17: error: overflow in implicit constant conversion [-Werror=overflow] src/util.c: In function 'format_bytes': src/util.c:6179:17: error: overflow in implicit constant conversion [-Werror=overflow] src/util.c:6180:17: error: overflow in implicit constant conversion [-Werror=overflow] src/util.c:6181:17: error: overflow in implicit constant conversion [-Werror=overflow] This code requires that off_t is defined as an 64bit off_t (off64_t) using -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64. Just removing these lines also shows that there is code in src/conf-parser.c that assert sizeof(off_t) == sizeof(uint64_t). src/conf-parser.c: In function 'config_parse_bytes_off': src/conf-parser.c:508:9: error: duplicate case value Does systemd really require LFS support => off_t to be defined as off64_t? Or could this code just modified to remove the assert_cc and modify the parse_bytes function to use an uint64_t instead off off64_t? Thanks, Peter
