Description
Describe the issue:
On i686, numpy defines:
npy_int32type aslong int.npy_uint32type aslong unsigned int.
These are incompatible with the stdint definitions of:int32_tasintuint32_tasunsigned int
This is causing h5py to fail to build on Fedora 40 due to the use of -Werror=incompatible-pointer-types. I think it's fairly reasonable to expect that the npy_*int* types to be completely interchangeable with the stdint types.
Reproduce the code example:
from numpy cimport int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t, uint64_t
...
def read_direct_chunk(self, offsets, PropID dxpl=None, unsigned char[::1] out=None):
...
cdef uint32_t filters
...
H5Dread_chunk(dset_id, dxpl_id, offset, &filters, chunk_buffer)Error message:
