Ok, this commit has broken the build: https://github.com/mono/mono/commit/db5f38402f39f6aeb30a5f12b4e90d7c943f6761

@DavidKarlas @marek-safar Could we make the code conditional to unbreak it?

barracuda156 commented 1 year ago

Apparently it has a broken ppc assembler too:

There have been a number of breaking commits for macOS PPC. This one broke ppc assembler: https://github.com/mono/mono/commit/f0a2c8ef306c93f9cfc38e4e0d802a590b33e5ee

I suspect these are wrong too: https://github.com/mono/mono/commit/02cdf6abca826279530ff9d89715a743130d127c (very likely wrong) https://github.com/mono/mono/commit/8332185abf23e2f27a536e6b7a08310aba8564fb https://github.com/mono/mono/commit/be104078673d2202c5cce85e81a3691b24265a68

@barracuda156 would you be interested in making PR to address the problems?

@barracuda156 would you be interested in making PR to address the problems?

@marek-safar Three issues fixed, rebuilding now again. Let me reach at least the successful build, otherwise we gonna need many incremental PRs.

P. S. At the moment I am not sure if r11 vs r12 issue is consequential. If it is (likely so, even if not immediately obvious), I may need some help to make it neatly: we cannot just revert https://github.com/mono/mono/commit/02cdf6abca826279530ff9d89715a743130d127c since ppc64le needs it, so register definitions should be set in some header globally, so that macOS picks r11 and other PPC picks r12.

___sync_val_compare_and_swap_8 should be replaced with respective __atomic* builtin, then passing -latomic it will work. Need to look up other errors.

P. S. On a side note, GSS linking appears broken: https://github.com/mono/mono/issues/20990#issuecomment-1537302326 I used a patch from that thread to disable GSS for now.

@marek-safar So it fails at the point of trying to use a pre-built mcs binary instead of building it from source. Is this a correct behavior? I would not expect any pre-built binaries to work on ppc (or any non-mainstream arch); likely we need to build everything from sources.

The pre-built binary appears to be for x86:

Here is what my mono shows:

@marek-safar I was able to build it with my old patches, but passing --disable-mcs-build to configure. As earlier, I also disable dtrace and gss.

Is it of some use without mcs? :)

barracuda156 commented 3 months ago

Trying to use with some builds I get this error:

The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `/opt/local/lib/mono/4.5/mscorlib.dll' directory.

Indeed, there is no such library:

Can I use some other binary in place of mcs?

barracuda156 commented 3 months ago

Okay, apparently we do need mcs, so the target has to be fixed and not disabled.

@alarixnia Have you tried building this on ppc via pkgsrc? Maybe you could advise something. The only relevant issue at the moment is to fix mcs, all macOS SDK issues are sorted, I believe, and mono itself builds.

barracuda156 commented 3 months ago

Ok, perhaps one thing we need to change is switch TLS to pthread, see: https://github.com/mono/mono/commit/5d96019cc21ef7228d89becac3a69870c797e5f9

@NattyNarwhal Maybe you could take a look?
