vlang fails for PowerPC: -latomic flag needed, Header file <sys/errno.h>, needed for module `sync` was not found

[barracuda156]

To begin with, -latomic must be added for darwin powerpc, otherwise build fails with:

After adding the flag, on 10.5.8 build fails with:

Hi there! Thanks for opening this ticket and for your comments on the original commit.

Good to know. I'll make this change. Judging by #62688, I also need to blacklist clang < 700.

That's interesting. I would've thought that errno.h comes with the command line tools?

Thank you. If you don't mind, condition it on build.arch being ppc ppc64 - that won't prevent building on 10.6 PPC and 10.6.8 Rosetta (conditioning on os.arch will break it for Rosetta).

For your machine, I would've thought that the header file would be in /usr/include/errno.h.

How should I fix that? In build files? Headers should be standard, this is on 10.5.8 with Xcode 3.1.4, nothing weird.

I'm happy to do that. Would you mind explaining a bit more why it breaks for Rosetta? Does it cause a build failure if the condition isn't applied here? Also, there are ​at least 4 different ports that apply -latomic based on os.arch. These might need to be changed.

I'm not sure yet, I agree it is odd that it can't find it. However, I don't think it's an issue with the port. Just to double check, does /usr/include/errno.h exist?

Also, I was just re-reading through the logs, and I noticed you were running an older version of the port. The ​current version will still fail to build but I'd like to check if the errors are different. You might need to apply the latomic patch since I haven't added it yet. Thanks for all your help.

Thank you!

I meant it likely just won't be used because os.arch will be x86_64, and then build gonna fail since ppc needs -latomic. I will need to test that specifically to say for sure (now on PPC machine and away from Intel).

Yes, there is /usr/include/errno.h which refers to /usr/include/sys/errno.h, which is also in place.

I've made a lot of changes to the vlang port recently. As a result, V finally builds on all the MacPorts buildbots. (yay!)

I'm hoping that this should help with the /usr/include/errno.h issue. Would you be happy to try the latest port (via sudo port selfupdate)? We can then examine any errors that come up. As always, thank you for your help on this.

Thank you. Just for the record, on 10.6 PPC it fails still with:

If this is different to the sys/errno.h error, would you mind sending the logs? Thanks.

It also ignores +universal and builds only one arch.

Thank you for letting me know. This might be quite difficult to fix, since vlang has an unusual build setup, but I'll see what I can do. Worst case scenario, I might disable the universal variant, but hopefully it won't come to that.

Attempt to build for ppc32 also fails on Leopard in the same way

I still don't understand why it can't find the header automatically. However, we can try manually including it and see if that works.

Would you mind adding -cflags -I${configure.sdkroot}/usr/include to the end of VFLAGS in the portfile. i.e.

VFLAGS="-v -cg -showcc -prod -cc ${configure.cc} -cflags [shellescape ${configure.cflags}] -cflags -I${configure.sdkroot}/usr/include" \

I'm not entirely sure what ${configure.sdkroot} is on your machine, so if that doesn't work, try -cflags -I/usr/include. Lets see if that changes anything.

Sure, I will attach a log now.

To be clear, 10.6 PPC is a developer build of 10.6, so it is not normally supported on Macports and elsewhere. I was requested not to file tickets specific to 10.6 PPC. So while I will be grateful to anyone who cares to fix a port for 10.6 PPC as well, this is in no way a standard expectation. Generally speaking, once a port builds for ppc32 on Leopard, there will be a way to get it onto 10.6 PPC. And considering interests of other developers and users, fixing anything PowerPC for 10.5.8 is always prioritized over alternatives.

Thanks for the logs. The key error seems to be this:

I'll do some digging. In the meantime, before you try the VFLAGS fix above for ppc32 Leopard, would you mind sharing the output of /opt/local/bin/gcc-mp-7 -v. Thanks.

Thanks for running that. I wanted to check whether gcc could find sys/errno.h, and it seems that it can. Ignore the VFLAGS fix; I don't think that it will make a difference.

Until I find a better solution, would you mind removing the errno reference in vlang? It's only required for a ​specific concurrency example, and so shouldn't make that much of a difference during runtime:

> sudo port fetch vlang
> sudo sed -i "" "10d" "$(port work vlang)/v-weekly.2022.13/vlib/sync/sync_darwin.c.v"
> sudo port -o install vlang

Just to note that this is not a fix, it's just a temporary patch until I find something better. This problem is a bit tricky :)

16. S. I use gcc6 now because of compilers transition which I mentioned above.

[harens (Haren S)]

Ok this should (hopefully) be an easy fix. From ​https://trac.macports.org/ticket/34064:

I got this from the ld(1) manpage on Leopard which includes '-no_pie' even though it looks like /usr/bin/ld doesn't actually support it (based on a quick check of "strings" output... sigh).

It seems like this flag is only added for ​backtraces to work on modern linux distros, so we should be able to patch this out. Would you mind running this block below? (n.b. it is different to the one above)

> sudo port extract vlang
> sudo sed -i "" "10d" "$(port work vlang)/v-weekly.2022.13/vlib/sync/sync_darwin.c.v"
> sudo sed -i "" "252d" "$(port work vlang)/v-weekly.2022.13/vlib/v/builder/cc.v"
> sudo port -o install vlang

Once we've tested whether all these fixes work, I'll write patches for the portfile to do all of this automatically. Thanks for your help.

That's on me. I forgot that -no-pie would also be in the V compiler.

I promise this will all be automated eventually :) but whilst we're playing around, would you mind adding the following command to our list?

sudo sed -i "" "91227d" "$(port work vlang)/vc-de63146da0a0f93628f8a65e70267e2c8d4c7ce1/v.c"

I'm going to go with a hunch and assume that v_win.c is Windows-only, and so doesn't need to be patched.

[barracuda156]

Unfortunately, it fails likewise.

[harens (Haren S)]

Unfortunately, it fails likewise.

I know this might not seem like it, but this is good news. We've fixed the -no-pie error and moved on to a different error. These are baby steps to success my friend :)

Our current error is the following, which also happened on 10.6 PPC previously:

/opt/local/lib/gcc6/gcc/ppc-apple-darwin9/6.5.0/include/stdatomic.h:40:1: sorry, unimplemented: '_Atomic' in Objective-C
typedef _Atomic _Bool atomic_bool;

The problem is that I still don't know how to fix this. Give me some time to think about this...

[harens (Haren S)]

Why don't we try the following:

I'm not sure if this Objective-C patch will work. We are also slowly removing the more complex functionality provided by the V programming language, which isn't ideal. However, I guess there's no point complaining if we can't build V in the first place.

What I'm more curious about is that V had no issues building without any of these patches on the 10.6 i386 and x86_64 buildbots. It's surprising that this much work is needed for 10.6 ppc and 10.5.8.

So the problem is likely not the status of 10.6 PPC but rather that ppc arch needs some fixes.

This error ​came up before with Rosetta, and I'm not surprised that it hasn't changed since I still don't know how to fix it yet...It's on my todo list :)

The suggested fixes so far are for non-Rosetta. Would it be possible to test them on your 10.5.8 and non-Rosetta 10.6 ppc machines? Thanks.

The suggested fixes so far are for non-Rosetta. Would it be possible to test them on your 10.5.8 and non-Rosetta 10.6 ppc machines? Thanks.

Yes, I will do that today, I hope. Line numbers did not change with the latest version update?

[harens (Haren S)]

Good catch. Here's the updated version:

The build succeeded! 🎉 Thank you for your perseverance and help in getting this far.

It's interesting that the _developer group doesn't exist, but that shouldn't be an issue. I'll push out a patch to fix the destroot.

Would you then mind updating your vlang port and trying again? Thanks.

In c811dd3a8f4308496948a2e52af5dc21dfb7c472/macports-ports (master):

vlang: create _developer group if non-existent

See: #64913

[ryandesign (Ryan Carsten Schmidt)]

You shouldn't create users or groups within phases like the destroot phase, since those phases will not run when the user receives a binary. adduser and addgroup are old commands that predate our distribution of binaries and shouldn't be used anymore. Their replacement is add_users which you should use instead (outside of any phase). See #38440 and browser:macports-base/doc/portfile.7​.

Should I rather wait until the issue that Ryan mentions is fixed?

[harens (Haren S)]

Should I rather wait until the issue that Ryan mentions is fixed?

I've patched it with the new weekly build. Thanks Ryan for the suggestion.

If you wouldn't mind updating, here's the new set of commands:

It worked!

36-248% port -v installed vlang
The following ports are currently installed:
  vlang @2022.16_0 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-04-19T05:59:55+0800'

[harens (Haren S)]

Yay! If you haven't done so already, would you mind trying out some simple test cases (maybe hello world, v doctor) just to check that everything works as expected.

What condition should I apply on these patches? Are they ppc or pre-10.7 issues?

Also, there's an issue pre-10.12 for some more advanced code that I'm aware of (​upstream issue). I might need your help testing some fixes at some point :) But thank you for all your assistance with this ticket.

[harens (Haren S)]

Oh and there's also Rosetta that I haven't dealt with yet. Would you mind deleting /usr/libexec/oah/vlib and building it again?

Thank you for the logs. I haven't changed anything recently, so I'm not yet sure about the error.

I'm afraid I have some exams I need to study for, which will finish in late June. I will get back to this ticket after that.

I have to apologize, that was some error on my end. Possibly due to migrating to a new libgcc11, but in any case, there is no problem with your solution, it builds on 10.6 PPC:

36-111% port -v installed vlang
The following ports are currently installed:
  vlang @2022.16_0 requested_variants='' platform='darwin 10' archs='ppc' date='2022-04-19T05:59:55+0800'
  vlang @2022.16_1 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-05-18T09:24:57+0800'

So only Rosetta and Tiger fail. Leopard and SL PPC work.

In 2407a52160ed289da9514e76f28c62a0be09065d/macports-ports (master):

vlang: update to weekly.2022.24

• Remove more hardcoded prefixes
• Add errno header patch
• Support postgresql module
• See #64913

[harens (Haren S)]

I've added the errno header patch to the portfile, and before I left, I sent the objective-c and -no-pie patches ​upstream.

On the systems where vlang successfully built with modifications, would you mind testing the latest release? My memory of this ticket is a bit hazy, but I'm hoping the patches should work.

I will test these next month, currently away from PPC hardware.

On 10.6.8 Rosetta vlang fails now with:

builder error: `builtin/` not included on module lookup path.
Did you forget to add vlib to the path? (Use @vlib for default vlib)
make: *** [all] Error 1

Unmodified portfile, gcc12.

[harens (Haren S)]

Thanks for testing. That seems to be the same error as before, which I guess makes sense since I haven't made any Rosetta modifications yet. I'll try and have a think about how to fix this.

Would you be able to test the port on the systems where it worked with modifications? I think that was 10.5 and 10.6 PPC. Thanks.

Sure, but by the end of month.

16. S. There is some discussion of PPC here: ​https://github.com/vlang/v/issues/15425

[barracuda156]

Just to give an update, current version of vlags builds fine on 10.6 PPC as-is, no trickery like before.

Rosetta still fails with:

Somehow this worked earlier, despite a lack of arch-specific code there. And now it does not.

UPD. There is nothing to be done here from the port maintainer side, to be clear. I hope I can handle it with upstream. I post updates on the matter just for information.
