Home Page Forums MAME QMC2 A request

I hate to be in a position to have to ask this, but I appear to have reached the limit of my technical expertise in this area (granted, a short distance), and I was hoping someone here would be willing to engage in a bit of digital hand holding, and walk me through the process of setting up, and compiling the latest version of QMC2 for MacOS...

i appear to be missing a step, or a library, and a step-by-step set of instructions would go a long way...

FWIW, previous MacOS builds would come on a disk image, with an installer, but that no longer appears to be the case...

Can you grab a CI build from GitHub Actions? Here’s the latest workflow run: https://github.com/qmc2/qmc2-mame-fe/actions/runs/8205015864

Well, I just grabbed a fresh copy of the source code, and it appears I'm missing Qt 4.8+

The Read Me instructions provide no clue where I might obtain this, or how to go about installing it, once I do...

You should not be missing qt 4.8, latest git uses qt5. It has been more than 10 years since I have used a mac so my ability to help or test is quite limited unfortunately. CI builds use qt from brew and SDL Image:
https://github.com/qmc2/qmc2-mame-f...0/.github/workflows/ci-macos.yml#L24-L29
Try installing qt from brew. As far as the SDL Image is concerned, either use the commands from the CI or just install it via the GUI.

Okay, here's where I swallow what little pride I have, and try to ignore my embarrassment...

Let's assume for a moment, that the extent of my knowledge when it comes to compiling anything is limited to compiling MAME about once a month, and even then, I keep a little 'cheat sheet' handy, to make sure I'm doing it right...

Now let's assume that I'm compiling QMC2 for the first time, from scratch...

I realize, and acknowledge that for some of you, this process is not unlike breathing, as in, you don't have to think about it...

i'm sorry to say that my level of expertise/experience is significantly below that...

I appreciate those of you who have reached out thus far, but I'm afraid I'm going to need at least some step-by-step directions, in order to make this happen...

With no guarantees that this will work, as I cannot test it:
0. clone the qmc2 git repository
1. run the commands from https://github.com/qmc2/qmc2-mame-f...0/.github/workflows/ci-macos.yml#L24-L29
2. run export PATH="${{ matrix.qtpath }}:$PATH", replacing {{ matrix.qtpath }} with the value from line 15 (/usr/local/opt/qt@5/bin) or 17 (/opt/homebrew/opt/qt@5/bin) depending on your macOS version and/or architecture. So e.g. export PATH="/opt/homebrew/opt/qt@5/bin:$PATH"
3. run make -j3, replacing 3 with the number of CPU cores you have

Before you try compiling yourself: what happens if you download https://github.com/qmc2/qmc2-mame-fe/actions/runs/8347086205/artifacts/1339743407 and try to run it?

Hi, thanks to belegdol, I could compile and upload codesigned new versions of QMC2 here:

https://mameonmacs.blogspot.com/2022/04/welcome-back-qmc2.html
Codesigning is done by me, if you do not trust me, then you would have to compile it by yourself ;-).

The Apple Silicon version is blazingly fast here, very nice status in overall (still some video playback issues, but I have to look deeper into this).

To the community: Feel free to use these builds on GitHub if it helps, otherwise, these links will be available at least until the next release.

Best.

Edit: Soon I will also upload my sh file for self-compile on Silicon Macs, but you have to take care of codesigning as well, which frankly I always struggle with. And besides the steps described by belegdol, you also must do a make install on your Mac after successfully compiling, which populates the necessary libraries and plugins into the app bundle. Then codesigning, first the plugin directories and Frameworks, then the binary and finally the app bundle. That's why I provide these app bundles codesigned, it's not that easy to have that in proper order on Silicon Macs with Apples rather extreme limitations.

So, I was preparing to set aside some time to plow through, and try to compile this myself (I still might, just for the experience...), when I saw that estefan3112 offered a pre-compiled, updated QMC2, along with installation instructions!

I am now successfully running version 0.244!

A *HUGE* Thank You to both belegdol, and estefan3112 for making this possible for me!

(A *Very* minor nitpick concerning the installation instructions; The unzipped 'qmc2' directory belongs in Root Library/Application Support, but even I was able to figure that out in fairly short order...;-) )

I may have a feature request, but I'll start a new thread for that...

Thanks again!

Great that it worked out for you. Out of curiosity: Silicon or Intel? Cause the Silicon build meets even stricter requirements on third party machines, and it would be good to know that it works.
I‘ll check the ReadMe, thanks, I was hoping to be precise enough on the root folder requirement…

Oddly enough, although I'm successfully running 0.244 of QMC2, I seem to be having some difficulty updating SDL to 2.30.1 (latest release as I type this).I'm still running 2.28, as any later version refuses to run because Apple cannot check it for malware, but that's a problem for another thread...
