Unfortunately, the usual linux tools (7zip, hpmount, loopback mount) are incapable of opening this file.

|
||||
To create a tarball suitable for Gitian input, there are two options:
|
||||
|
||||
Using Mac OS X, you can mount the dmg, and then create it with:
|
||||
```
|
||||
$ hdiutil attach Xcode_7.3.1.dmg
|
||||
$ tar -C /Volumes/Xcode/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/ -czf MacOSX10.11.sdk.tar.gz MacOSX10.11.sdk
|
||||
```
|
||||
|
||||
Alternatively, you can use 7zip and SleuthKit to extract the files one by one.
|
||||
The script contrib/macdeploy/extract-osx-sdk.sh automates this. First ensure
|
||||
the dmg file is in the current directory, and then run the script. You may wish
|
||||
to delete the intermediate 5.hfs file and MacOSX10.11.sdk (the directory) when
|
||||
you've confirmed the extraction succeeded.
|
||||
|
||||
```bash
|
||||
apt-get install p7zip-full sleuthkit
|
||||
contrib/macdeploy/extract-osx-sdk.sh
|
||||
rm -rf 5.hfs MacOSX10.11.sdk
|
||||
```
|
||||
|
||||
The Gitian descriptors build 2 sets of files: Linux tools, then Apple binaries
|
||||
which are created using these tools. The build process has been designed to
|
||||
avoid including the SDK's files in Gitian's outputs. All interim tarballs are
