[systemd-devel] systemd requires LFS?

[Peter Lindgren]

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
