Created attachment 857229 [details] build.log Occurred to me on both guppy.ia64 and lgentoo3.s390 It seems like it is about a mismatch between size_t and npy_uintp not matching the same size. I guess it is because of missing #ifdef ? > numpy/core/src/multiarray/alloc.c:434:1: error: conflicting types for ‘PyDataMem_UserNEW’; have ‘void *(size_t, PyObject *)’ {aka ‘void *(long unsigned int, struct _object *)’} > 434 | PyDataMem_UserNEW(size_t size, PyObject *mem_handler) > | ^~~~~~~~~~~~~~~~~ > In file included from numpy/core/src/multiarray/alloc.c:13: > numpy/core/src/multiarray/alloc.h:17:1: note: previous declaration of ‘PyDataMem_UserNEW’ with type ‘void *(npy_uintp, PyObject *)’ {aka ‘void *(unsigned int, struct _object *)’} > 17 | PyDataMem_UserNEW(npy_uintp sz, PyObject *mem_handler); > | ^~~~~~~~~~~~~~~~~ > numpy/core/src/multiarray/alloc.c:480:1: error: conflicting types for ‘PyDataMem_UserFREE’; have ‘void(void *, size_t, PyObject *)’ {aka ‘void(void *, long unsigned int, struct _object *)’} > 480 | PyDataMem_UserFREE(void *ptr, size_t size, PyObject *mem_handler) > | ^~~~~~~~~~~~~~~~~~ > numpy/core/src/multiarray/alloc.h:23:1: note: previous declaration of ‘PyDataMem_UserFREE’ with type ‘void(void *, npy_uintp, PyObject *)’ {aka ‘void(void *, unsigned int, struct _object *)’} > 23 | PyDataMem_UserFREE(void * p, npy_uintp sd, PyObject *mem_handler); > | ^~~~~~~~~~~~~~~~~~
