Lazarus 4.2 and OSX 10.14 How do you make it build?

[fsckit]

I'm trying to get Lazarus to work on my Mac(specs at bottom of post). I've followed this set of instructions https://wiki.freepascal.org/Installing_Lazarus_on_macOS#Step_2:_Xcode_Command_Line_Tools, tested the compiler with a hello-world program, its ok.

I've installed from binary, and the IDE runs, but it refuses to build anything. These are the messages I get. The project is just the initial blank form. Adding a button and code for the button to show a hello world message box produces this same error.

>    Compile Project, Target: /Users/leon/tmp/project1: Exit code 1, Errors: 4
>    Error: linker: Undefined symbols for architecture x86_64:

Changing the compiler from /usr/local/bin/fpc to /usr/local/lib/fpc/3.2.2/ppcx64 in the IDE options as suggested on another page doesn't help.

It looks like the linker is broken.  Has anyone any ideas?




My Mac, in case this matters:
Mac Mini 2012
MacOS Mojave 10.14.6
16GB RAM
~500GB SSD with about 80GB free

Lazarus 4.2, FreePascal 3.2.2

I used Delphi a lot in the 90s, but have been away for a while.

My VM with macOS Mojave is broken now, but I remember the same issue. It can be fixed in the following way:

• Add {$DEFINE DisableCocoaModernForm} to /etc/fpc.cfg
• Run "make clean bigide" in the Lazarus folder
• Sometimes there is another compilation error now, at "initIDECocoaConfigForms" in ide/main.pp -- delete this line and run "make bigide" now.

Just a stab in the dark, but maybe it helps:
You could try using "-WM10.14" in the compiler options.

Go to Project -> Project Options -> Compiler Options -> Custom Options
In the text box "Custom Options" enter this:

Code: Pascal  [Select][+][-]

1. -WM10.14

Is that an early intel or a late PowerPC? Mac Mini 2012 That is not modern Apple hardware.
The -WM option is probably useless in that case since that is only for Apple M series. That is only for newer Apple hardware.
I can't test it anymore since my older Mac mini (intel) died about two years ago, I only have an M4.

Suggest to install an older version of Lazarus and an FPC to match. (3.0.4 is known by me to work for both Powerpc and intel)

I also wonder how you could install recent xcode? May be possible but unlikely?

I may be wrong: the mini's are just a toy for me and I don't use them frequently.
Otherwise you may be the victim of progress.

The 2012 Mac Mini is an intel i5. The last one with upgradable RAM. The last PowerPCs were 2006.

Otherwise you may be the victim of progress.

The whole Macintosh line are toys.
Why does the documentation say it works with 10.10 and later?

@Hansaplast
That doesn't seem to have any effect, except that it now compiles the whole thing and leaves us with that same linker error.

Add {$DEFINE DisableCocoaModernForm} to /etc/fpc.cfg
Run "make clean bigide" in the Lazarus folder

After doing these, and starting Lazarus.app, we get the "Configure Lazarus IDE" window. There is an error in the compiler page:

Error: system.ppu not found. Check your fpc.cfg.

I don't know what system.ppu is or where it should be.

Thanks

I used to build my project on a 2012 Powerbook running Sierra. From memory, I used FPC3.2.2. Thats two releases before Mojave

XCode was not a problem as long as you installed just the XCode command line tools, not the full kit and caboodle.

Reducing down to 3.8 works! It seems 4.2 isn't compatible.

Thanks guys

Maybe I should note that my Lazarus is in the Documents folder to give me full file permissions.
