Hi, I'm encountering the following linker error when building haproxy-1.9.7
make CC=arm-softfloat-linux-gnueabi USE_OPENSSL=1 ... LD haproxy /usr/bin/../lib/gcc/arm-softfloat-linux-gnueabi/8.3.0/../../../../arm-softfloat-linux-gnueabi/bin/ld: src/fd.o: in function `fd_rm_from_fd_list': haproxy-1.9.7/src/fd.c:267: undefined reference to `__ha_cas_dw' collect2: error: ld returned 1 exit status Makefile:994: recipe for target 'haproxy' failed make: *** [haproxy] Error 1 Eyeballing the code I think it's because USE_THREAD is not defined and __ha_cas_dw is only defined when USE_THREAD is defined
