Since moving get_rate() and get_size() from tc to lib, on some systems we fail to link because of missing math lib. Move the functions that require math lib to their own c file and add -lm to dcb that now use those functions. ../lib/libutil.a(utils.o): In function `get_rate': utils.c:(.text+0x10dc): undefined reference to `floor' ../lib/libutil.a(utils.o): In function `get_size': utils.c:(.text+0x1394): undefined reference to `floor' ../lib/libutil.a(json_print.o): In function `sprint_size': json_print.c:(.text+0x14c0): undefined reference to `rint' json_print.c:(.text+0x14f4): undefined reference to `rint' json_print.c:(.text+0x157c): undefined reference to `rint' Fixes: f3be0e6366ac ("lib: Move get_rate(), get_rate64() from tc here") Fixes: 44396bdfcc0a ("lib: Move get_size() from tc here") Fixes: adbe5de96662 ("lib: Move sprint_size() from tc here, add print_size()") Signed-off-by: Roi Dayan <roid@nvidia.com> --- Notes: v3 - Modify _IS_JSON_CONTEXT comparison order. v2 - As suggested by Petr.
