The last IOS cross compiler https://github.com/smolt/ldc-iphone-dev/releases based on 0.17.0-alpha1, which is 3 years old.

I want to ask for suggestion, how can i build a cross  LDC2 compiler with just betterC function to work.

Thanks in advance.

As you can see, the guy who did a lot of work with getting D running on iOS and other non-Mac Apple platforms has not been able to do anything with it for the last year or two.

Looking at his ldc fork, there's not much he had to change to the compiler by the end:

https://github.com/smolt/ldc/commits/ios

You could try applying those same patches to the latest ldc release and get it working. If you just want betterC, that's all you need, though I can't imagine it would take much to get druntime and Phobos updated too, as he had them both working well a couple years ago.

We are looking for someone to take over the iOS port, so if you or someone else is interested, please try it out. You can ask technical questions of the ldc devs directly in our forum or github:

Thanks for you suggestion Joakim.

I try follow your suggestion,  get all commit from origin branch (116 commit by Dan Olson fro IOS brnach).

When I try cherry pick the first commit, get conflict the line number is 6232.  (the ios branch is base on cpp and master ldc is move to d).

I will try more but I guess It is hard for me to made it work.

Huh, I didn't look that far back in the branch, may not be worth merging. How is his last release working? Do you want only betterC?  If so, you may be better off backporting the betterC patch that got it working later, shouldn't be much to that one.

Thanks for your help.

The side thing is betterC change also base on d based branch,  which is very hard to backporting to cpp branch.

No, it only disables 4-5 things, so while you're right that it applies towards ddmd, it should be pretty easy to manually backport to the old C++ frontend. I plan to do so for the ltsmaster branch of ldc, its last C++ version, this week: you can apply that pull to Dan's ios branch or easily port it yourself.

My betterC backport is up, try it on Dan's iOS branch:

When I cherry pick the commit 08041422, git report the IOS branch dose not have function `getCAssertFunctionName` , `DtoCAssert`  there seems missing some old commit from  IOS branch to ltsmaster branch.  I don't know how many and how to compare to get all the missing commit to work.

Thanks for you help again.

Are you starting from the top, with the oldest commit first? Because the older commits supply those functions.

You may not want to cherry-pick if you're not used to doing it, and just apply the patch itself:
