I am trying to rebuild glibc with -DMALLOC_DEBUG=1 $ DEB_CFLAGS_APPEND="-DMALLOC_DEBUG=1" dpkg-buildpackage -b -uc -us -nc (-nc is because I am stopping the build sometimes to check the output)
But I don't see "-DMALLOC_DEBUG=1" in the generated compiled lines... like in: i686-gnu-gcc-10 /home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd/RPC_termctty_open_terminal.c -c -std=gnu11 -fgnu89-inline -pipe -O2 -g -fdebug-prefix-map=/home/paul/malloc/glibc-2.31=. -Wall -Wwrite-strings -Wundef -fmerge-all-constants -frounding-math -fstack-protector-strong -Wno-parentheses -Wstrict-prototypes -Wold-style-definition -fmath-errno -Wa,-mtune=i686 -isystem /home/paul/malloc/glibc-2.31/debian/include -I../include -I/home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd -I/home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc -I../sysdeps/mach/hurd/i386 -I../sysdeps/mach/hurd/x86 -I../sysdeps/mach/hurd/i386/htl -I../sysdeps/mach/hurd/htl -I../sysdeps/hurd/htl -I../sysdeps/mach/htl -I../sysdeps/htl -I../sysdeps/pthread -I../sysdeps/i386/htl -I../sysdeps/mach/hurd -I../sysdeps/gnu -I../sysdeps/unix/bsd -I../sysdeps/unix/inet -I../sysdeps/mach/i386 -I../sysdeps/mach/include -I../sysdeps/mach -I../sysdeps/i386/i686/fpu -I../sysdeps/i386/i686 -I../sysdeps/i386/fpu -I../sysdeps/x86/fpu/include -I../sysdeps/x86/fpu -I../sysdeps/i386 -I../sysdeps/x86 -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/float128 -I../sysdeps/ieee754/ldbl-96/include -I../sysdeps/ieee754/ldbl-96 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754/flt-32 -I../sysdeps/hurd/include -I../sysdeps/hurd -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/ieee754 -I../sysdeps/generic -I../hurd -I/home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd/ -I../mach -I/home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/mach/ -I.. -I../libio -I. -nostdinc -isystem /usr/lib/gcc/i686-gnu/10/include -isystem /home/paul/malloc/glibc-2.31/debian/include -D_LIBC_REENTRANT -include /home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/libc-modules.h -DMODULE_NAME=libhurduser -include ../include/libc-symbols.h -DPIC -DTOP_NAMESPACE=glibc -o /home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd/RPC_termctty_open_terminal.o -MD -MP -MF /home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd/RPC_termctty_open_terminal.o.dt -MT /home/paul/malloc/glibc-2.31/build-tree/hurd-i386-libc/hurd/RPC_termctty_open_terminal.o with the hello packsage I do see the -DMALLOC_DEBUG=1 I admit glibc is a much more complex than hello... but it is also why I want to make sure I do it right because it is a bit long to compile. Also, I am a bit confused, that if I use ~/.config/dpkg/buildflags.conf I see changes in dpkg-buildflags output... but the man say is no more automatically exported... and so it is unclear what I need to do for it to be applied to the dpkg-buildpackage command.
