MinGW64 build
by Robert Szalai 05 Nov '19

05 Nov '19

Hi all, I've been trying to build CLN from windows 64, with some success. It compiles fine, but does not work. The problem is that WIN64 is LLP64, and not ILP64 as Linux. CLN uses long to store pointer data, but size_t or ssize_t should be used as it is guaranteed to be the size of the pointer everywhere. The attached patch was my attempt. Could somebody tell me where else should I look? Pointers are also encoding some metadata in the bits that are set to zero by alingnment, what is this data? There is also some hashing of pointers. Thanks, Robert
