Unpack XIP on Linux

Unpacking XIP files on Linux:

  1. Install xar from https://mackyle.github.io/xar/
  2. Install pbzx from https://github.com/NiklasRosenstein/pbzx (use gcc -llzma -lxar -I /usr/local/include pbzx.c -o pbzx and copy the binary into your PATH)
  3. use xar -xf XIP_FILE -C /path/to/extract/to
  4. Change to the directory where you extracted the file.
  5. Use pbzx -n Content | cpio -i to extract the contents.

pbzx compilation should be

gcc -I /usr/local/include pbzx.c -o pbzx -llzma -lxar

because on OS X the linker allows the -l command line options to precede the source files. On Linux it does not.

On modern Linux you need to fix configure.ac: https://askubuntu.com/a/1195797

Also note that you have to install libbz2-dev (and liblzma-dev) on Debian/Ubuntu to extract at least the Xcode xip archive.

In addition to this, you also need to make the changes mentioned in this issue mackyle/xar#10

Alternatively, with less patching & compiling required: use the tool developed by bitcoin

https://github.com/bitcoin-core/apple-sdk-tools

python extract_xcode.py -f Xcode_11.3.1.xip | cpio -d -i

Hi, the following worked for me (inverted lib order while linking) :

sudo ldconfig # after installing xar
gcc pbzx.c -o pbzx -llzma -lxar
