I want to run my binaries on a 64bit system, and I would prefer to take advantage of its capabilities. But I have no use for 64 bit pointers, which, in my case, are responsable for a large size overhead. Since the m32 flg is not supported, I suppose the target should be x32, which the musl site says is experimental (maybe that information is outdated?) > > Fortunately, these are easy to make with the musl-cross-make tool. I'll try and see if I'm able to grokk it! Regards Jorge
