Compiling for 2009 iMac

[Tony]

Hello everyone. Hoping someone can point me in the right direction. The computer Id like to use: Model A1225 iMac 24" Early 2009 9.93GHz 2 Duo (E8335) 4Gb SODIMM NVIDIA FeForce GT 120 (256Mb) Machine: iMac9,1 Running macOS El Capitan version 10.11 At the moment Im trying xcode 8.2.1 There is a page on compiling the cores and so forth, with a video utilising command line and text suggesting use xcode Im going around in circles, so perhaps if I supply screen shots of the errors, someone can help…

Anyone have any suggestions? Thank you

In your top image it looks like you’re trying to build RetroArch Cg, which requires additional libraries. Just try building the RetroArch target and it should hopefully go better.

For xcodebuild/xcode-select, try running xcode-select -r to reset it back to the default path; it shouldn’t be pointing at the command line tools.

Thank you! OK, tried resetting the paths and made no difference. So turned my attention to using Xcode. First picture shows the 2 projects there, including the one you mentioned with the dependencies. I gather its not a simple matter of removing one. As seen in the next picture though, several xcode projects are on offer, and I thought perhaps that being for different platforms, so I chose what seemed an appropriate one for my old machine. The resulting errors are show in the third image.

I guess that while Ive used code including C before, this is a brand new platform and unfamiliar IDE for me.

Does the version of xcode look appropriate to you (see my orig cry for help), and I selecting the wrong thing? Looks like I need my hand held for this stage.

Ah, ok. Yes the version of Xcode should be fine. Doing it inside of Xcode it going to be a lot easier than with xcodebuild so let’s stick with that.

There are many .xcodeproj files (and one .xcworkspace) that are lightly documented at https://docs.libretro.com/development/retroarch/compilation/osx/#retroarch-compilation. In your first picture in your original post and the first picture in this latest post, you were using RetroArch.xcodeproj, which for versions of macOS earlier than 10.13 is the best one to use. (The ones with _iOSnn are all for versions of iOS and can be ignored here.)

In your second post, first image, at the very top next to the window management buttons, there is a play button, a greyed out stop button, and then a toolbar that in your photo says “RetroArch Cg”. It is a selectable menu and you can change it to just “RetroArch” from there.

[Tony]

Aha! Thanks for the pointers - I have a successful build! very cool. Um, I gather that its not deployed, or it hasn’t taken it to the app stage where I can run it? Or am I not looking in the right places?

[warmenhoven]

So there are a few things you can do now.

One option is just to run it directly from Xcode by hitting the triangle Play button at the top left in the first picture on your second post. That’s a typical developer workflow.

In your first picture on your second post you are pointing at the Products, and now RetroArch.app should be black instead of red. If you right-click on it there should be an option to “Reveal in Finder” or similar. From there you would be able to run it directly outside of Xcode. You could also copy it into the /Applications folder from there.

One other thing to check is whether you built it as a debug or release build. There really isn’t that much difference between the two except that release has a few extra compiler optimizations so may run slightly faster. In Xcode there should be an option to “Edit Scheme” (typically ⌘-Shift-comma) and change the Build Configuration from Debug to Release.

By default a build produced from Xcode will not have all of the assets, core info files, etc., so you will need to use the Online Updater to download everything.

All good Eric, I really appreciate the time your spending on this. I located the Debug/Release option and the location of the compiled file. Does the error dump below mean anything to you? In the meantime I’ll look at the debugging options in there…

Code Signature Invalid typically means that the OS is expecting the app to be properly signed by a developer, but it doesn’t think it is.

In the OS System Settings app there should be something like a Security preference pane that you can use to relax that restriction.

Alternatively, in Xcode’s preferences, there should be an Accounts tab that will let you log in using your Apple ID. After you’ve logged in, select the RetroArch project in the Xcode navigator (at the top of the tree in the first picture on your second post) and there should be a tab for Signing & Capabilities that you can use to change the Team or Developer to your Apple account.
