PCem v17?

[brunocastello]

Any chance of an update to v17 for macOS? I am interested in trying it on both Intel Mac and M1 Mac*

• = When I can get an M1 one.

The dynamic core in v17 is currently 'broken' to the extent that if you compile in macOS it will run extremely slowly and basically be unusable. I can confirm this myself as I built from source and tested it in Mojave. I have successfully built v16 and patched in the experimental Open GL 3.0 support as well (to use shaders). It works great. If you would like a copy, let me know and I will provide a DropBox link. Note that I am using an Intel Mac so it will only run in Rosetta 2 on an M1.

Oh damn, but thanks. @almeath I sure want a copy please, at the moment I have an Intel Mac (2013 MacBook Pro Retina "13, i7 Dual Core 2.8GHz). Probably not one of the strongest Macs, and will probably struggle a bit, but I want to try out for FIFA 9X games, with a view for a future Apple Silicon upgrade between the end of 2021 and start of 2022.

EDIT: If possible I would also like to fork the patched v16 repo so I could compile myself in the future.

Actually, it is easier for me to just fork it now and let you build from there directly. Should be available now:

Build instructions are in the README.md

Let me know if you need any help.

I think it is a good idea to hold off on Apple Silicon until there have been several generations of updates, which also allows more time for the Mac community to catch up with the transition. I like to move across when things are more established, rather than live on the frontier so to speak. For example, they are only just getting started with adding Apple Silicon support for Homebrew, and that will be a lengthy process. I know there is Rosetta 2, but I want full performance.

[brunocastello]

Thanks! I'll give it a go sometime this weekend, and I will report back too.

EDIT: I've got this error after running make:

codegen_allocator.c:56:28: error: implicit declaration of function 'rand' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
block_nr = rand() & MEM_BLOCK_MASK;

I have latest Xcode and command line tools, brew 3.0.0, required packages installed (sdl2, wxmac, openal-soft).

[almeath]

I’ll build this for you and post a link to the compiled output. However, in the meantime, can you try installing this in homebrew:

brew install gcc

After that, try running configure and make again.

If that fails, can you show me your full Terminal output after running both the ./configure commands?

It might be that you are missing a C / C++11 dependency. I had similar errors when building custom DOSBox branches and needed to install support for older C compilers. The default support in the version of clang that comes with macOS might not have full backwards compatibility.

[almeath]

Here is the compiled output, with the pcem executable built.

I am still interested to know if you can build it yourself, as I may have to add some extra brew dependencies to the build instructions.

after brew install gcc and trying to compile again, I'm stuck with the same error:

codegen_allocator.c:56:28: error: implicit declaration of function 'rand' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
block_nr = rand() & MEM_BLOCK_MASK;

No luck. Well, I'll download your build and try it out.

Here's the output for your build:

MacBruno-Pro:PCemV16macOS-master Bruninho$ ./pcem
dyld: Library not loaded: /usr/local/opt/wxmac/lib/libwx_osx_cocoau_webview-3.0.dylib
Referenced from: /Users/Bruninho/Downloads/PCemV16macOS-master/./pcem
Reason: image not found
Abort trap: 6
MacBruno-Pro:PCemV16macOS-master Bruninho$

I've seen that before with one of the previous builds. I have to remember how I managed to overcome this one...

[almeath]

Just confirming you ran the command to install the dependencies?

brew install sdl2 brew install wxmac brew install openal-soft

EDIT: I included your missing dylib in this zip file: these dependencies are included inside the PCem app that @kyr0 included with his earlier build. Maybe try putting these in your usr/local/lib ?

Yes

I think the problem is the versioning. I do have the missing libraries in usr/local/lib, but they are newer versions (not just this one, there are others). I'll try these now

[brunocastello]

No luck. I'm on WxMac 3.0.5.1 according to homebrew, and apparently pcem wants 3.0. I remember I've hit the same roadblock when I tried v14, but I did not insist back then. And there is no webview dylib within this latest version.

[brunocastello]

This is the output when I add the webview library:

MacBruno-Pro:PCemV16macOS-master Bruninho$ ./pcem
dyld: Library not loaded: /usr/local/opt/wxmac/lib/libwx_osx_cocoau_webview-3.0.dylib
Referenced from: /Users/Bruninho/Downloads/PCemV16macOS-master/./pcem
Reason: Incompatible library version: pcem requires version 6.0.0 or later, but libwx_osx_cocoau_webview-3.0.dylib provides version 5.0.0
Abort trap: 6
MacBruno-Pro:PCemV16macOS-master Bruninho$

[almeath]

OK, this appears to be a Catalina / Big Sur issue which I need to investigate. I am using Mojave on my main system, but I tested the binary in Big Sur on my MacBook Pro and it produced the same error about the missing library for libwx_osx_cocoau_xrc-3.0.dylib

[brunocastello]

Yup, I’m on Big Sur 11.2. Apparently wxmac 3.0.5.1 from homebrew does not have some libs like webview.

[almeath]

Yeah, I’m on 11.2 as well. I’m glad I kept it off my iMac for the time being. I believe the error will not appear in Catalina either.. this issue is exclusive to Big Sur. I hope to get to the bottom of this but in the meantime I’ll need to amend my build instructions to warn it is not Big Sur compatible.
