Bug ID: 212035
Summary: libnv fails to compile on 10.3Stable during buildworld
with -DNDEBUG in CFLAGS (low priority)
Product: Base System
Version: 10.3-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-b...@freebsd.org
Reporter: dewa...@heuristicsystems.com.au
CC: freebsd-amd64@FreeBSD.org
CC: freebsd-amd64@FreeBSD.org
Defining NDEBUG on the CFLAGS variable inhibits compilation of libnv as
follows:
# cd /pd3/src; MAKEOBJDIRPREFIX=/usr/obj/pd3/src/tmp
cc -fpic -DPIC -O2 -pipe -g0 -ggdb0 -DNDEBUG -DSTRIP_FBSDID -UDEBUGGING
-UDEBUG -DUSB_HAVE_DISABLE_ENUM -march=core-avx-i
-I/pd3/src/lib/libnv/../../sys -I/pd3/src/lib/libnv -std=gnu99
-Qunused-arguments -fstack-protector -Wsystem-headers -Werror -Wall
-Wno-format-y2k -W -Wno-unused-parameter -Wstrict-prototypes
-Wmissing-prototypes -Wpointer-arith -Wreturn-type -Wcast-qual -Wwrite-strings
-Wswitch -Wshadow -Wunused-parameter -Wcast-align -Wchar-subscripts -Winline
-Wnested-externs -Wredundant-decls -Wold-style-definition
-Wmissing-variable-declarations -Wno-pointer-sign -Wno-empty-body
-Wno-string-plus-int -Wno-unused-const-variable -c
/pd3/src/lib/libnv/../../sys/kern/subr_nvlist.c -o subr_nvlist.So
/pd3/src/lib/libnv/../../sys/kern/subr_nvlist.c:982:36: error: unused parameter
'nvl' [-Werror,-Wunused-parameter]
nvlist_next_nvpair(const nvlist_t *nvl, const nvpair_t *nvp)

/pd3/src/lib/libnv/../../sys/kern/subr_nvlist.c:998:36: error: unused parameter
'nvl' [-Werror,-Wunused-parameter]
nvlist_prev_nvpair(const nvlist_t *nvl, const nvpair_t *nvp)
---------
Whereas same comand without NDEBUG produces an object file.
Discovered while trying to build a world without DEBUG code, and inadvertently
-DNDEBUG when I should -UDEBUG. :}
