Kexts use boot-args as well, as can be seen when disassembly by calls to PE_parse_boot_argn (usually exported, _PE_parse_boot_argn 8027A8EC on the iOS 6.1.3 kernel, discovered by Haifisch). The arguments of the kernel are largely the same as those of macOS. Arguments may be directed at the kernel proper, or any one of the many KExts (discussed below). Like its macOS counterpart, iOS's XNU accepts command line arguments (though the actual passing of arguments is done by iBoot, which as of late refuses to do so). IRQ and FIQ handlers will also have their own execution stack which is specified by _irqstack. The bootstrap thread has its own specific static kernel stack, which is specified by _intstack.
The kernel maintains thread specific stacks by calling kernel_memory_allocate, this allocates stacks in the specified kalloc zone. On production and development devices, the kernel is always stored as a statically linked cache stored at /System/Library/Caches//kernelcache that is decompressed and run on startup. This makes exploitation harder as the location of kernel code cannot be known. Afterwards, FPC will function correctly.As of iOS 6, the kernel is subject to ASLR, much akin to Mountain Lion (OS X 10.8). To install them manually, open "/Applications/Utilities/Terminal", execute "xcode-select -install" and choose "Install". Xcode 5 and later however no longer install the command line tools by default, which are required by FPC. Xcode 5+ compatibility (OS X 10.9 Mavericks for OS X 10.8 Mountain Lion, see below)įPC 3.2.0 is qualified for use with Mac OS X 10.4 till macOS 10.15. These workarounds are required because we do not pay Apple 79 euro per year, which would prove you can trust us. If this does not work, you may first have to go to System Preferences -> Security & Privacy -> General, and "Allow apps downloaded from: Mac App Store and Identified developers". If you get the message that the FPC installer was created by an unknown developer and cannot be opened, right-click on the installation package and choose "Open" in the contextual menu. "Unknown developer" error when installing (Mac OS X 10.7 Mountain Lion and later) * For additional information visit our homepage, forum, wiki, and FAQ: * For an overview what changed from previous 1.8 versions (includes incompatibilities with earlier versions) see:
* For an overview what changed from previous 2.0 versions LazarusIDE - the IDE, visual components and help files You need to download and install all three packages fpc, fpc-src and LazarusIDE.įpc - the Compiler, some command line tools, base units and non visual components like database accessįpc-src - the sources of fpc and its packages, needed for code browsing For older Macs use the Mac OS i386 version.
