Przy próbie kompilacji w Win10 biblioteki pugixml do pugixml.obj mam błędy:
undefined reference to `__asan.........
Mój program w C++ używa tej biblioteki. Pod Linuxem nie mam tych
komunikatów.
Katalog pugixml/ zawiera plik Makefile. Czy mam coś zmienić w Makefile?

Strzelam: asan_xxxx to funkcje odwołujące się do biblioteki
AddressSanitizer, a ty tej biblioteki nie masz?

Szybko googlając wyszukiwarka podpowiada też:
"AddressSanitizer is a part of LLVM starting with version 3.1 and a
part of GCC starting with version 4.8"

Mimo, że zamieniłem:

ifeq ($(config),sanitize)
CXXFLAGS+=-fsanitize=address,undefined
-fno-sanitize=float-divide-by-zero,float-cast-overflow
-fno-sanitize-recover=all
LDFLAGS+=-fsanitize=address,undefined
endif

na:

ifeq ($(config),sanitize)
# CXXFLAGS+=-fsanitize=address,undefined
-fno-sanitize=float-divide-by-zero,float-cast-overflow
-fno-sanitize-recover=all
# LDFLAGS+=-fsanitize=address,undefined
endif

(tzn. wykomentowałem) nadal mam ten błąd undefined reference.
Nie wiem jak poprawić Makefile, żeby nie było tego błędu.
