Re: [Libguestfs] [PATCH 2/2] Cast return value of be64toh to uint64_t before printing.

From: "Richard W.M. Jones" <rjones(a)redhat.com&gt; With glibc 2.16-24.fc18, be64toh is a macro around __bswap_64 which is defined as: unsigned long long int __bswap_64 (unsigned long long int __bsx); Unfortunately on 64 bit platforms, unsigned long long int cannot be printed using the expansion of PRIu64 ("%lu") resulting in about a dozen errors such as: ldm.c:1129:5: error: format '%lu' expects argument of type 'long unsigned int', but argument 11 has type 'long long unsigned int' [-Werror=format] This commit corrects the problem by casting the result to uint64_t, although I'm fairly sure that this is really a bug in glibc. --- src/ldm.c | 28 ++++++++++++++-------------- 1 file changed, 14 insertions(+), 14 deletions(-)
