Subject: [PATCH] gnu: libcbor: Fix cross-compiling to 32-bit architecture
Date: Thu, 12 Dec 2024 14:04:35 +0000

* gnu/packages/compression.scm (libcbor)[arguments]: Disable examples because
they don't build during cross-compilation. The callback definition
`find_string` in examples/streaming_parser.c uses `size_t` as type for
argument `len` which is 4 bytes on a 32bit platform. However, the callback
handler of type `cbor_callbacks.string` to which `find_string` is assigned
expects an `uint64_t`. Since the examples are not required this patch will
disable them from the build.
