Dear maintainer,
consider the following warnings emitted by blhc (line breaks are mine;
see the attached "test.log" file for an input that reproduces this
problem):
LDFLAGS missing (-Wl,-z,relro): make VERSION="v-amd64-linux" MAKE="make" \
CC="gcc -std=gnu99 -Wall" CFLAGS="-O2 -m64 -g -O2 \
-fdebug-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong \
-Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 \
-Wl,-z,relro" DEFS="-DARCH_AMD64 -DSIZE_64 -DOPSYS_UNIX -DOPSYS_LINUX \
-D_GNU_SOURCE -DGNU_ASSEMBLER -DDLOPEN -DINDIRECT_CFUNC" \
CPPFLAGS="-Wdate-time -D_FORTIFY_SOURCE=2" LDFLAGS="-Wl,-z,relro" \
AR="ar" ARFLAGS="rcv" RANLIB="ranlib" INCLUDES="-I../../objs \
-I../../include -I.." libposix-os.a)
CPPFLAGS missing (-D_FORTIFY_SOURCE=2): VERSION=v-amd64-linux \
CPP="gcc -x assembler-with-cpp -E -P -Wdate-time -D_FORTIFY_SOURCE=2" \
CPPFLAGS="-Wdate-time -D_FORTIFY_SOURCE=2" \
../../config/gen-posix-names.sh _SC_ ml_sysconf.h
One could argue whether blhc should even consider lines like these,
because they do not actually contain any compiler calls; perhaps it
would be more sensible to delay the warnings to the actual compiler
calls that the recursive make or the script perform. However, it
doesn't hurt to be on the safe side and check calls like these, too.
The problem is that the reportedly missing flags aren't missing at
all: The former call contains "-Wl,-z,relro" in both CFLAGS and
LDFLAGS; the latter call contains "-D_FORTIFY_SOURCE=2" in both CPP
and CPPFLAGS.
So, why does blhc think that those flags are missing?
Best regards,
Fabian
