building macos ventura #67

mkm commented 2023年10月18日 10:40:05 +02:00

I run on macos ventura, and my default environment comes with Apple clang version 14.0.3.

Just running make doesn't work:

I see in the readme that the recommended way to build on is to pass CC=clang-11 or CC=gcc-10
I'm trying to figure out how to build ngn/k without having to install clang-11 or gcc-10.

I'll report my findings here

In OpenBSD, I also remove those flags, though I also have to remove the -ldl one, because the dl* functions in OpenBSD are in libc, there is no libdl library. It seems like using the same build options in all platforms is not possible. I don't know what the best portability fix for this is, I don't know much about linking stuff. Not a big deal, though, it's easy to change that line each time I update.

I noticed the same problem on macOS:

clang: fatal error: -Wl,-E: 'linker' input unused [-Wunused-command-line-argument]

For a long time, I have been able to build on macOS without any problems. Removing the argument -Wl,-E from the makefile fixes the problem, but there is probably a better solution.

I also tried adding -Wno-unused-command-line-argument to disable the warning that's causing the build failure, but then I get this error:

ld: unknown options: -E 
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm not sure what this linker argument is supposed to do.

@SirBogman I’m guessing it’s to export dynamic symbols from the executable so they can be called from dynamic libraries. I think this is the default for dylan files. (Not sure of the terminology for this last.)
