Compile error on Mac

dushyant — Tue, 17 Sep 2024 11:22:47 GMT

Hi,

I'm getting a compile error on Mac:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX14.0.sdk/usr/include/c++/v1/locale:2827:22: no member named 'GS_realloc' in namespace 'std'; did you mean simply 'GS_realloc'? _Tp* __t = (_Tp*)std::realloc(__owns ? __b.get() : 0, __new_cap);

The same code compiles fine with MSVC on windows.

Anyone faced this error?

Thanks.

Hi,

That's a weird error and I haven't experienced it myself.
But a different thing I noticed is, that you are using the MacOSx14.0 devkit. I would try to use the same as the recommended deployment target. So that's 10.15 for AC25+.
It's a bit tough to get older macOS devkits installed. I think I got them from here: https://github.com/phracker/MacOSX-SDKs
but proceed at your own risk ^^

Hope that helps,
Bernd

Hi Bernd,

Thanks for your reply. I'm building for AC27. Where do you find which version no. is the recommended for it?

Re: Compile error on Mac

BerndSchwarzenbacher — Fri, 24 Nov 2023 06:03:55 GMT

I thought there was a mention of it somewhere in the API docu or at the site of the SDK downloads. But now I can't find it anymore.

But you can find the LSMinimumSystemVersion for the libraries in the AC API SDK or also for the Archicad main app on macOS. This is one entry in the Info.plist files. For AC27 all of these say "10.15.0". Here's the main one on my machine:

/Applications/GRAPHISOFT/Archicad 27/Archicad 27.app/Contents/Info.plist

Re: Compile error on Mac

dushyant — Fri, 24 Nov 2023 08:08:28 GMT

Okay, that's the same for me (10.15.0). I tried with MacOSX10.15.sdk and the project failed to configure.

-- The CXX compiler identification is unknown

In CMakeLists.txt: set(CMAKE_OSX_SYSROOT "/path/to/MacOSX-SDKs/MacOSX10.15.sdk")

Btw, could this lead to compatibility issues with higher versions of MacOS when distributed?

Re: Compile error on Mac

BerndSchwarzenbacher — Fri, 24 Nov 2023 10:03:04 GMT

I think the main issue could be, that your XCode version is not compatible with the SDK.

You could try changing the MinimumSDKVersion version to 10.15 there as well:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Info.plist

This fixed it for me IIRC and I'm running XCode 14.1. For editing the plist file you can use e.g. the command line utility "plutil" and convert to xml first and then back to binary. Also make a backup of this Info.plist in case anything goes wrong.

Sorry if all of this is vague. It's been a while since I've last done this and my notes on it are a bit scattered.

Also you might need to adapt the Info.plist in your builds of the Add-On itself to match.

About compatibility: I can't say for sure, but I'm not too worried about it myself, since GS distributes AC with this exact same MinimumSystemVersion.

Best,
Bernd

Hi,

I changed the MinimumSDKVersion to 10.15 in XCode's Info.plist.

I moved the MacOSX10.15.sdk dir to /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
passed the option to CMake to use MacOSX10.15.sdk, but it doesn't seem to look there for it.

Are you working in the XCode IDE itself? How do you set it to use any particular SDK? Do you use CMake?

Update: I made CMake to use the specific SDK but it fails to generate the project with it..

Re: Compile error on Mac

OK, so good news and bad news:

Good news: The issue should definitely be with the MacOSX14.0 SDK, since in the file mentioned in your original question, it uses std::realloc instead of realloc as in older DevKits like the ones I have installed (13.0 and 10.13). And in the file Archicad SDK there's following line in the file Support/Modules/GSRoot/GSMalloc.hpp:#define realloc(p, s) GS_realloc(p, s)And the combination explains the issue, since GS_realloc really isn't in the std namespace. And switching the MacOSX SDK to an older version should really help.

Another possibility could be to also put GS_realloc in the std namespace or add another #define std::realloc(p, s) GS_realloc(p, s) before any includes. Not sure if any of it works and it's very hacky, but could be a temporary solution.
Bad news: I'm actually using MacOSX13.0 SDK instead of the MacOSX10.13/10.15 devkits I thought I used. I have 10.13 installed and I'm sure I've used it before, but probably through one XCode update I got 13.0 installed and it was switched then. So I don't have recent experience about switching the MacOSX SDK apparently 😅 (I'm using Cmake as well).

What's your error in cmake during the build generation now?

Re: Compile error on Mac

dushyant — Sun, 26 Nov 2023 12:49:14 GMT

Hi,

Thanks for the info.

I discovered that the error occurs when I include <iostream> library. So it could be related to the std namespace somehow (though I don't have any components in use from the library, and I could disable it).

I tried:

#define realloc(p, s)	GS_realloc(p, s)

That didn't help.

CMake just fails to identify the manually supplied MacOSX SDK as a valid one. I tried with a custom path and also by placing the SDK in the same place as the main SDK in XCode: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs

It fails in both cases. I removed the SDKs so I don't have the actual error messages to quote.

How do you supply the custom SDK to your CMake? Are you using CMake within the XCode IDE?

Anyway it seems I can get around this error by just avoiding the iostream library and use the latest SDK (v14) from XCode.

Thanks for the help and the info.

Good to hear that you found a way to get around the error!

Supplying another line of

#define realloc(p, s) GS_realloc(p, s)

won't help, since it's already defined like this anyway.

I suggested to try the following (note the extra std:: in front of realloc😞

#define std::realloc(p, s) GS_realloc(p, s)

On Mac I'm using CMake sometimes with XCode and sometimes with Visual Studio Code.

About switching the macOS SDK, there are some hints in the readme on the github repo I provided above: https://github.com/phracker/MacOSX-SDKs
But I haven't tested it.

Re: Compile error on Mac

dushyant — Thu, 30 Nov 2023 07:59:42 GMT

Hi,

#define std::realloc(p, s) GS_realloc(p, s) <--- is not defining a valid macro name, because of the '::'.

Sorry, missed out the notes on the github repo page.

Thanks again for the suggestions and help!

Re: Compile error on Mac

BerndSchwarzenbacher — Thu, 30 Nov 2023 08:36:43 GMT

Ah yeah, you're right, that won't work then.

I just thought maybe also the include order might make a difference.

So maybe including iostream before any Archicad API include could work (also make sure it's before the includes you have in associated header files of .cpp files).
But I'm not sure if there would be an effect if parts of the code use different memory allocators then.

Re: Compile error on Mac

dushyant — Thu, 30 Nov 2023 09:04:56 GMT

Maybe including iostream before AC headers could have a different behaviour.

Anyway, I don't really need iostream here. So it's no problem for now 🙂

Hi,

I may have found a workaround for the issue. I am new to Macs and a beginner at C++ so take it with a grain of salt.

As usual, all works fine on Windows.

What I did was #undefine the malloc functions right before #include-ing an std libraries. This seems to solve the issue of duplicated / overwritten defines, like in the example bellow:

// Archicad 27 API Includes #include "ACAPinc.h" #include "APICommon.hpp" #include "APIEnvir.h" #include "DGModule.hpp" #include "DGBrowser.hpp" // these define the GS_realloc and so on // Undefine macros that cause issues (potential fix) #undef calloc #undef malloc #undef free #undef realloc // Include standard or third-party headers that need the original memory functions #include <string> #include <cstring> #include <vector> #include <ctime> #include <unordered_map>

I don't know if it's correct, but at least it compiled with no error.

For now I'm using the 14.2 sdk, that comes with Xcode.

Regarding the minimum 10.15 version, I managed to set it up via CMake, using the base template from GitHub, but I don't think it had any effect on the issue above.

In BuilAddOn.py:

def GetProjectGenerationParams (workspaceRootFolder, buildPath, addOnName, platformName, devKitFolder, version, languageCode, additionalParams): ... if platformName == 'WIN': ... elif platformName == 'MAC': projGenParams.extend (['-G', 'Xcode']) # Ensure the deployment target is macOS 10.15 projGenParams.append('-DCMAKE_OSX_DEPLOYMENT_TARGET=10.15')

If you find an actual fix, please let me know!

Thanks!

This issue occurs because there was a change in the latest Xcode SDK that is not compatible with the Development Kit. Although earlier it was possible to always use the latest Xcode, unfortunately it's not the case anymore.

Hopefully there will be a solution for this in the future, but in the meantime please make sure that you are using Xcode 14.2 for compilation. The tricky part here is that it's not very straightforward to install an earlier version of Xcode, but it's possible by following the steps below.

Go to https://developer.apple.com/download/all/?q=xcode.
Download and install these two packages:
- Command Line Tools for Xcode 14.2,
- Xcode 14.2.
Make sure that the system uses this newly downloaded Xcode by running the command below (replace the app location with your current installation location).

sudo xcode-select -s /Applications/Xcode_14.2.app

After this change everything should compile without any issues.

I figured out a very dumb solution that worked for me.

I noticed that the MacOSX14.sdk is just a shortcut that points to MacOSX.sdk
I simply duplicated and renamed the shortcut to MacOSX14.0.sdk (with the explicit) .0 so the compiler sees the path and the build works.

Hi Victor! Any news on an update? Xcode 14.2 is not compatible with macOS Sonoma thus this workaround won't work with new Macs.

Re: Compile error on Mac

Ralph Wessel — Tue, 14 May 2024 11:58:30 GMT

There is a name clash between the STL and the Archicad SDK, but it can be avoided. The compiler is currently seeing the GS version first, which is shadowing std::realloc - hence the compiler suggestion that this is what you mean.

I recommend ordering your header file includes so all STL headers are read first, followed by any Archicad SDK header includes.

Re: Compile error on Mac

Victor Baboi — Fri, 17 May 2024 12:29:00 GMT

I had a new update on my (old) mac and reordering seems to have done the trick this time. If I find any more details I will let you know.

By the way, I have Xcode 15.2 on Ventura 13.6.7.

I faced the same issue on MacOS (Intel chip) Ventura 13.5
