go-macholibre
A library for dealing with wrapping and unwrapping Mach-O multi-architecture binaries (a.k.a. Universal binaries).
Developing
When developing / running tests, note that there is data being referenced that is not checked into the source tree but instead residing in a separate store and is managed via git-lfs. You will need to install and initialize git-lfs to work with this data:
git lfs install
git lfs pull
Grab local tooling:
make bootstrap
To run tests:
make fixtures
make unit
Note on testing: since lipo is used to verify that the resulting binaries are as expected, these test fixtures
can only be generated on a Mac.
To run all checks:
make

Functions ¶
func IsUniversalMachoBinary ¶
IsUniversalMachoBinary returns true if this is a valid multi-architecture (universal) binary.
Types ¶
type ExtractedFile ¶
type ExtractedFile struct {
Path string
UniversalArchInfo
}
type ExtractedReader ¶
type ExtractedReader struct {
Reader interface {
io.Reader
io.ReaderAt
}
UniversalArchHeader
}
func ExtractReaders ¶
func ExtractReaders(r io.ReaderAt) ([]ExtractedReader, error)
type UniversalArchHeader ¶
type UniversalArchHeader struct {
UniversalArchInfo
Offset uint32
Size uint32
Align uint32
}
A UniversalArchHeader represents a fat header for a specific image architecture.
type UniversalArchInfo ¶
type UniversalFile ¶
type UniversalFile struct {
UniversalFileHeader
Payloads [][]byte
}
A UniversalFile is a Mach-O universal binary that contains at least one architecture.
func NewUniversalFile ¶
func NewUniversalFile() UniversalFile
NewUniversalFile creates a new universal file object
func (*UniversalFile) Add ¶
func (u *UniversalFile) Add(binaries ...string) error
Add takes one or more paths to Mach-O formatted binaries to be added to the universal binary.
type UniversalFileHeader ¶
type UniversalFileHeader struct {
Magic uint32
Count uint32
Arches []UniversalArchHeader
}
