Fails to start gui on macOS (version 1.2.0)

[kyrre]

While version 1.1.0 works fine the newest version 1.2.0 fails to launch on macOS:

macOS 14.5 ghidra via homebrew (with rebuilt native binaries)

GHIDRA_INSTALL_DIR=/opt/homebrew/Caskroom/ghidra/11.1.1-20240614/ghidra_11.1.1_PUBLIC pyhidra -g

This is where it gets stuck on 1.2.0. Not sure how to debug this further

Can you supply the print results of the ctypes.find_library calls in runmac_app at the end of launcher.py?

[kyrre]

Like this?

def _run_mac_app():
    # this runs the main event loop
    # it is required for the GUI to show up
    objc = ctypes.cdll.LoadLibrary(ctypes.util.find_library("libobjc"))
    ctypes.cdll.LoadLibrary(ctypes.util.find_library("AppKit")) # required

    print(ctypes.util.find_library("libobjc"))
    print(ctypes.util.find_library("AppKit"))

    ...

/usr/lib/libobjc.dylib /System/Library/Frameworks/AppKit.framework/AppKit

Thanks for providing the additional information. The values you shared seem to be correct, but we're still working to see if we can replicate this error.

Can you attempt to update _run_map_app with the following? It seems that there are some unusual behaviors when Java starts up so this tries to work around it. Please let us know if this works.

def _run_mac_app():
    # this runs the event loop
    # it is required for the GUI to show up
    import ctypes
    import ctypes.util
    from ctypes import c_void_p, c_double, c_uint64, c_int64, c_int32, c_bool, CFUNCTYPE

    CoreFoundation = ctypes.cdll.LoadLibrary(ctypes.util.find_library("CoreFoundation"))

    def get_function(name, restype, *argtypes):
        res = getattr(CoreFoundation, name)
        res.argtypes = [arg for arg in argtypes]
        res.restype = restype
        return res

    CFRunLoopTimerCallback = CFUNCTYPE(None, c_void_p, c_void_p)
    kCFRunLoopDefaultMode = c_void_p.in_dll(CoreFoundation, "kCFRunLoopDefaultMode")
    kCFRunLoopRunFinished = c_int32(1)
    NULL = c_void_p(0)
    INF_TIME = c_double(1.0e20)
    FIRE_ONCE = c_double(0)
    kCFAllocatorDefault = NULL

    CFRunLoopGetCurrent = get_function("CFRunLoopGetCurrent", c_void_p)
    CFRelease = get_function("CFRelease", None, c_void_p)

    CFRunLoopTimerCreate = get_function(
        "CFRunLoopTimerCreate",
        c_void_p,
        c_void_p,
        c_double,
        c_double,
        c_uint64,
        c_int64,
        CFRunLoopTimerCallback,
        c_void_p
    )

    CFRunLoopAddTimer = get_function("CFRunLoopAddTimer", None, c_void_p, c_void_p, c_void_p)
    CFRunLoopRunInMode = get_function("CFRunLoopRunInMode", c_int32, c_void_p, c_double, c_bool)

    @CFRunLoopTimerCallback
    def dummy_timer(timer, info):
        # this doesn't need to do anything
        # CFRunLoopTimerCreate just needs a valid callback
        return

    timer = CFRunLoopTimerCreate(kCFAllocatorDefault, INF_TIME, FIRE_ONCE, 0, 0, dummy_timer, NULL)
    CFRunLoopAddTimer(CFRunLoopGetCurrent(), timer, kCFRunLoopDefaultMode)
    CFRelease(timer)

    while CFRunLoopRunInMode(kCFRunLoopDefaultMode, INF_TIME, False) != kCFRunLoopRunFinished:
        pass

Sorry for the late reply. Replacing the function with the one you provided fixes it.
