That's probably due to the same problem that causes the error you
post below, as that program is also written and and compiled with FPC.
(2) The disk image for UPInterfaces is already mounted.
The installer for Free Pascal for Xcode Integration Kit
appears to proceed normally.
Indeed, then this program is not started.
When working with the default Carbon project:
The projects builds OK.
It does? That's strange, since it requires several changes to work
with XCode 22.1 at least (maybe it's beter with XCode 2.0).
(1) When the program runs, if Command-Q is pressed, it quits
with exit status 0.
(2) When the program runs, and the program's main menu ("Hello"
in this case) is pressed, attempting to reach the Quit menu item,
the program exits with status 207 and the output to the run log as
pasted below.
(3) Additionally, after running the default compiled Carbon
program and clicking the program's main menu ("Hello" in this
case), the "Automatically hide and show the Dock," (System
Preferences, Dock) feature quit working. Option-Command-D still
works, however. Trying to re-set the feature to On from the Pref
panel fails. Control-Clicking on the divider line in the actual
Dock and selecting "Turn Hiding On" succeeds. This entire cycle is
repeatable.
(2) and (3) probably have a similar cause. For some reason, some
procedures in the Carbon framework no longer function correctly if
floating point "invalid operation" exceptions are enabled. FPC
enables these at startup time, while the C runtime does not. You can
work around this problem by adding the following three lines at the
start of your main program:
asm
mtfsfi 6,1
end;
This masks the "invalid floating point operation" exceptions.
