The last IOS cross compiler

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.

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.

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:

but I can not build the llvm use Dan Olson script or cmake, it 
report error. (I can build new llvm without problem, but after I

Sounds like something wrong in your environment then, as I just 
checked out his last llvm ios-release_362 branch in a linux/x64 
VPS, ran the configure command from his llvm script (see link), 
ran make, and everything's building fine:

https://github.com/smolt/ldc-iphone-dev/blob/master/tools/prepmake-llvm

You'll have to investigate what's different about your build 
environment that you can't seem to build an almost-stock llvm 
3.6.2.

Thanks a lot, after I modify llvm/autoconf/AutoRegen.sh (to allow 
use the version of my pc), and regenerate config.guess,  cmake 
build start to working.

and now I get a old ldc version with betterC support.

(I am not test it on iphone yet, but it can build).

now I wish some maybe there is not much modify to bring the last 
ldc master to iphone(only betterC work still can do more stuff, 
with less bug compare to druntime).

Looks like he modified about 35 files in ldc for his iOS branch, 
the diff is not that big. If you're diligent, you could probably

if I do not use real type in IOS i can skip this ?

No idea, I haven't really used iOS, as I haven't bought an Apple 
device in almost 15 years. It's your port, you get to make the 
decisions. :)

Darwin can generally imply either macOS, tvOS or iOS, as far as I

 Darwin can generally imply either macOS, tvOS or iOS, as far as 
 I can tell.


Thanks for tips.


 Joakim

I speed the weekend on this and with no good results.

abi-ios is not work with lts master anymore,  because a lot code 
is changed.(not sure how to fix it)

And after cherry pick ios-llvm tls patch to LLVM 37 or 60, none 
of them work. I try fix but not able to made it buildable. (base 
on ldc issue 1081, llvm no need tls patch if I understand correct)

and make file also break so I has to remove the runtime folder to 
build ldc(not buildable because cpp error).

Do you mean ltsmaster or master? There shouldn't be much change 
with the former.

The TLS patches shouldn't be needed after llvm 3.8 or so, ie you 
should be able to use a stock llvm for iOS:

That makes no sense: there are no C++ files in the runtime, only 
C and D. Anyway, if you only care about betterC, you don't want 
to build the runtime, so doesn't matter.

My suggestion is that you simply build his working ldc for iOS 
project, but with the betterC patch I linked you backported. Once 
you're sure that's working, you can try these more advanced 
steps. Have you tried that? It's not clear.

the origin ldc with your patch is working. but I find it is very 
limit betterC support with old version(some code will not work, 
and fixed at late dmd/ldc version).

The patched ldc not build because a lot old code Dan Olson write 
is not working any more( ldc  cpp interface changed, or llvm cpp 
interface changed).  I try to fix but never get it working. (I 
patch all 36 files)

Looking at his commits diffed against ltsmaster, there isn't much 
to port, particularly once you throw out the TLS commits and the 
floating-point cross-compilation code that has since been added 
in the official repo, maybe 500-800 lines largely in his new iOS 
ABI files:

https://github.com/ldc-developers/ldc/compare/ltsmaster...smolt:ios

Of course, adapting that diff to upstream takes careful knowledge 
of ABI details and how llvm and LDC handle them, which you may 
not be familiar with. You may want to see if one of the LDC devs 
is interested in porting this patch upstream, by posting in their 
forum:

https://forum.dlang.org/group/ldc

Some of them do consulting work for companies, maybe you could 
pay one of them to do it.
