With. I run
eval $(dpkg-buildflags --export=sh)
which corresponds to
export CFLAGS="-g -O2 -fstack-protector-strong -Wformat
-Werror=format-security"
export CPPFLAGS="-D_FORTIFY_SOURCE=2"
export CXXFLAGS="-g -O2 -fstack-protector-strong -Wformat

export FCFLAGS="-g -O2 -fstack-protector-strong"

export GCJFLAGS="-g -O2 -fstack-protector-strong"
export LDFLAGS="-Wl,-z,relro"
export OBJCFLAGS="-g -O2 -fstack-protector-strong -Wformat
-Werror=format-security"
export OBJCXXFLAGS="-g -O2 -fstack-protector-strong -Wformat
-Werror=format-security"
before compiling.
