Dear Maintainer, #define NETTLE_USE_MINI_GMP 0
/* We need a preprocessor constant for GMP_NUMB_BITS, simply using sizeof(mp_limb_t) * CHAR_BIT is not good enough. */ #if NETTLE_USE_MINI_GMP -# define GMP_NUMB_BITS 32 +# define GMP_NUMB_BITS 64 #endif Although NETTLE_USE_MINI_GMP is defined as zero in Debian, /usr/include/nettle/version.h still conflicts between arches (e.g. amd64 and i386). This, in turn, prevents co-installation of the nettle-dev package and severely hinders other projects. As the subsequent #define is not used, please resolve this conflict by defining GMP_NUMB_BITS with an #error message. This will help any user who attempts to use GMP_NUMB_BITS without checking if it is defined. Once this conflict is resolved, nettle-dev can become Multi-Arch: same.
