Emu48 for intel Mac
Does anyone know of a version of emu48 calculator emulator that runs on intel macs?

I tried the mac emu48 https://sourceforge.net/projects/emu48ma...48/1.25b4/ and it is powerpc only and thus not runnable anymore on modern macs or versions of MacOS after 2009. And the version on hpcalc.org https://www.hpcalc.org/details/5829 looks like exactly the same old powerpc version that I tried 1.25 Beta 4.

RE: Emu48 for intel Mac
Source code is here, so maybe someone could try compiling it for Intel Macs?

RE: Emu48 for intel Mac
That source code appears to be incomplete. I downloaded it, opened the project in the latest Xcode, changed the Base SDK to something recent, and started a build. I got this error:

Code:

error: /Users/thomas/xcode/emu48mac-master/Calculators: No such file or directory

As the error message says, there is no Calculators directory in the source code. This is not buildable in this state, and there's no documentation included that might help figure out what to do, either.

RE: Emu48 for intel Mac
Calculators is an empty folder in SourceForge, so maybe make an empty folder with that name, and then see what errors you get next? I wonder if it's intended to contain something like ROM images or UI skins.

RE: Emu48 for intel Mac
After creating an empty Calculators directory, the next error is about the call [LogController appendLog: szString]; in kmlparser.m, line 1137. It's not clear to me why the compiler complains about that line, since LogController does look like it should be defined, but anyway, I moved past it by commenting out that line and calling NSLog(@"%@", szString); instead. There were no further build errors.

Now when I run it, this appears on the console:

Code:
2018-11-14 17:09:03.310113-0500 Emu48[783:7571] [default] Unable to load Info.plist exceptions (eGPUOverrides)

...which I'm guessing is harmless. The app starts, but doesn't show a window. In the File menu, the top item is New Calculator, which has an arrow indicating a submenu, but the submenu is, unsurprisingly, empty.

Any suggestions what I should drop into that Calculators folder? I don't think I have any suitable ROM images.

UPDATE: The "About" box text contains this, among other things: "Note: some included files are not covered by the GPL; these include ROM image files (copyrighted by HP), KML files, and faceplate images." That sounds like the missing pieces. Presumably it needs the same kind of files as Emu48 on other platforms?

RE: Emu48 for intel Mac
I downloaded and installed the "Emu48 20th Anniversary" package (in Windows), choosing the "Lite" install, and copied the BMP, KML, and ROM files from its installation directory into the Calculators directory in my Emu48 build area in MacOS. After rebuilding, now the New Calculator menu is no longer empty, but selecting any item causes this to get logged on the console:

RE: Emu48 for intel Mac
What is it that Emu48 shall do for you? If you're just looking for a plain old HP48/49/50 emulator, there may be another one that just works.
- For the Saturn-based calculators (48S(X), 48G(X), 49G) I'd suggest x48 - I haven't actually tried it, but I can't think of a reason why it shouldn't work on OSX.
- For the ARM-based calculators (49G+, 50G) there's x49gp which I know has been used successfully on OSX. There are several contributors of that project floating around these forums (including myself), which means you would at least get decent support and quick fixes if it somehow doesn't work.
For more OSX-compatible emulators, check out this older thread. (The bits I wrote about x49gp have become a bit outdated though.)
I know that Emu48 has some features which these replacements don't have (e.g. interface reorganization via KML scripts, or a pretty good built-in RPL and Saturn ASM debugger; x49gp's only debugging facility is aimed at ARM code), but they can calculate, draw graphs, run RPL programs, and most of the other stuff you can do with a physical calculator.

RE: Emu48 for intel Mac
I, for one, want to run various hp rom images e.g. hp10b, hp17b, hp20s, hp28c, hp32, hp42s etc. This is what emu48 does under windows. Would prefer not to have to boot a virtual machine running windows to do it.

RE: Emu48 for intel Mac
Ah, bummer. Have you tried using the Windows version in Wine? It works for me on Linux, and as far as I know Wine is also available for x86-based Macs.

RE: Emu48 for intel Mac
Hello!

I successfully tried the same using Virtual Box running Windows 8 on my MacBook Pro under Mac OS 10.11. I had no luck with the "normal" EMU48 because I couldn't get the ROM image installed (and was too lazy to read the full instructions). Instead I downloaded this easy installation "easy_emu48_gx_e.zip" form somewhere which already has the ROM image. It works fine. All of what I have used to do it is available for free apart from the computer itself.

However I had no luck compiling the original project on my Mac. Using the project file as it is I get a strange error message for which I could not find a solution. And starting a new project into which I copied the source files resulted in a flood of compiler errors. As I am no particular fan of the HP48 series (to put it mildly) I called it a day at this point.

Max

Seems to run ok using the free PlayOnMac too.

Crossover has the advantage of creating a nice desktop icon to launch it, whereas PlayOnMac's shortcut icons are not runnable for some reason - but you can double click within PlayOnMac and emu48 launches fine. On the other hand, launching via PlayOnMac gives a new instance each time, whereas Crossover just takes you to the same single instance each time (making it harder to run all the calcs and make pretty pictures for posting here...;-)

I was not aware of this project, I will give it a run, thanks for the link.

You are right, but if you duplicate the bottle you can then have multiple instances running the same app. Just tried it and it works. Be aware that you will have to deal with the issues of the app that it not multi-instance aware (log file, state file, etc).

Sylvain
