Using pre-built zld
Closed this issue · 7 comments
It appears that zld doesn't build on OSX 10.15 for ARM, and maybe that's due to missing arm variants in dylibs. During make, I get:

In that case, maybe it's time to give up on recommending people build it from scratch, and just distribute a pre-built fat binary. Can someone provide the built version? @thii ?
Are you sure you're not using an x86 cmake?
Here's a prebuilt version: zld.e58a15e.tar.gz
What do you mean by x86 cmake? I'm just doing git clean -dfx && make on an x86 10.15 mac
Ahh, sorry I thought you were trying to build on an arm Mac.
I think it's just linking with the wrong SDK. You need at least macOS 11.0 SDK which is only included in Xcode 12.2+.
OK makes sense, I think I'll just put up the pre-built version then
