Build options

This specific page documents specific build options and flags that can be used in order to build packages for Procursus. The variables listed here can all be found within the Makefile.

The table below showcases supported commands (along its function) provided by Procursus

Command	Function
make, make all, make package	Compiles the entire Procursus suit and packs it into Debian packages
make env	Prints the proenv shell function to stdout to give a cross-compilation environment in your POSIX shell (e.g make env >> ~/.zshrc)
make everything	Similar to make and make all, except that every supported host platform gets compiled and packed into Debian packages
make (tool)	Compiles a specific tool, sending headers and libraries to BUILD_BASE so that they can be accessed by other packages
make (tool)-package	Similar to make (tool). After compiling, the tool gets packed into a Debian package
make rebuild-(tool)	Re-builds an entire package
make rebuild-(tool)-package	Similar to make rebuild-(tool). After re-compiling, the tool gets packed into a Debian package
make (tool)-deps	Finds and returns a list of dylibs linked to (tool)
make clean	Cleans out BUILD_STAGE, BUILD_STAGE, and BUILD_WORK
make extreme-clean	Similar to make clean, cleaning out BUILD_SOURCE and BUILD_DIST

These commands can have specific build flags attached to them; the table below showcases build flags you can pass as options when using Procursus build commands

Variable	Required	Function	Example
MEMO_TARGET	Yes	Specific architecture type that packages are built in	iphoneos-arm64
MEMO_CFVER	Yes	CoreFoundation value of the minimum *OS version to compile for	1700, which represents the CoreFoundation version that corresponds to iOS 14
NO_PGP	No	Specifies whether GPG signature checks on tarballs should be skipped. Set this option to 1 to enable it	NO_PGP=1
MEMO_QUIET	No	Allows unnecessary warnings to be silenced. Set this option to 1 to enable it	MEMO_QUIET=1
TARGET_SYSROOT	Yes	Specifies the PATH of your iOS SDK. Check the Makefile to see what each supported build system defaults to	/usr/share/SDKs/iPhoneOS.sdk on iOS
MACOSX_SYSROOT	Yes	Specifies the PATH of your macOS SDK. Check the Makefile to see what each supported build system defaults to	/usr/share/SDKs/MacOSX.sdk on iOS
BUILD_ROOT	No	Allows for specific packages or architecture suits to sent to a different place once compiled, rather than within the Git respository itself	This can be any path, as long as the directory exists
MEMO_FORCE_LTO	No	On macOS, LTO is enabled automatically, however on Linux and FreeBSD, it must be explicitly enabled in cctools-port.	MEMO_FORCE_LTO=1
MEMO_ALT_LTO_LIB	No	Specify an alternative libLTO.{so,dylib} path that will be passed to the linker with -lto_library.	/usr/local/llvm11/lib/libLTO.so
