config EXAMPLES_ELF
	bool "ELF Loader Example"
	default n

	depends on ELF
	---help---
		Enable the ELF loader example

config EXAMPLES_ELF_FSMOUNT
	bool "Mount external file system"
	default y
	depends on EXAMPLES_ELF_EXTERN

config EXAMPLES_ELF_FSREMOVEABLE
	bool "Removable file system"
	default n
	depends on EXAMPLES_ELF_FSMOUNT

config EXAMPLES_ELF_DEVMINOR
	int "ROMFS Minor Device Number"
	default 0
	depends on EXAMPLES_ELF_ROMFS
	---help---
		The minor device number of the ROMFS block. For example, the N in
		/dev/ramN.  Used for registering the RAM block driver that will hold
		the ROMFS file system containing the ELF executables to be tested.
		Default: 0

config EXAMPLES_ELF_FSTYPE
	string "External file system type"
	default "vfat"
	depends on EXAMPLES_ELF_FSMOUNT
	---help---
		The minor device number of the ROMFS block. For example, the N in
		/dev/ramN.  Used for registering the RAM block driver that will hold
		the ROMFS file system containing the ELF executables to be tested.
		Default: 0

config EXAMPLES_ELF_DEVPATH
	string "Block driver device path"
	default "/dev/ram0" if EXAMPLES_ELF_ROMFS
	default "/dev/mmcsd0" if EXAMPLES_ELF_FSMOUNT
	depends on EXAMPLES_ELF_ROMFS || EXAMPLES_ELF_FSMOUNT
	---help---
		The path to the ROMFS/External block driver device.  This must match
		EXAMPLES_ELF_DEVMINOR for the case of ROMFS.  Used for mounting the
		file system containing the ELF executables to be tested.  Default:
		"/dev/ram0" for ROMFS, "/dev/mmcsd0" for the external file system.

config EXAMPLES_ELF_NOSTRIP
	bool "Do not strip debug symbols"
	default n
	depends on DEBUG_SYMBOLS
	---help---
		By default, if debug symbols are enabled (via CONFIG_DEBUG_SYMBOLS), then the
		ELF executables will also retain debug symbols in the resulting ELF binaries.
		Select this option if you do not want that behavior, this option will permit
		debug symbols in the base code but will strip debug symbols out of the ELF
		binaries for a smaller ROM file system image.

config EXAMPLES_ELF_SYSCALL
	bool "Link with SYSCALL library"
	default n
	depends on LIB_SYSCALL
	---help---
		Link with the SYSCALL library.  By default, all undefined symbols
		must be provided via a symbol table.  But if this option is
		selected, then each ELF test program will link with the SYSCALL
		library and will interface with the OS system calls.  In this case,
		those symbols will not be undefined.  If the SYSCALL library is
		available then you probably will want to select this option.

config EXAMPLES_ELF_LIBC
	bool "Link with LIBC"
	default n
	---help---
		Link with the C library (and also math library if it was built).
		By default, all undefined symbols must be provided via a symbol
		table.  But if this option is selected, then each ELF test program
		will link with the C library and will not require symbol table
		entries.  You probably will NOT want this option, however,
		because it will substantially increase the size of code.  For
		example, a separate copy of printf() would be linked with every
		program greatly increasing the total code size.  This option is
		primarily intended only for testing.

config EXAMPLES_ELF_CXXINITIALIZE
	bool "C++ Initialization"
	default y
	depends on HAVE_CXX && HAVE_CXXINITIALIZE
	---help---
		By default, if CONFIG_HAVE_CXX and CONFIG_HAVE_CXXINITIALIZE are
		defined, then this example will call the NuttX function to
		initialize static C++ constructors.  This option may be disabled,
		however, if that static initialization was performed elsewhere.

config EXAMPLES_ELF_UCLIBCXX
	bool "uClibc++ is installed"
	default n
	depends on UCLIBCXX
	---help---
		By default, uClibc++ is not installed and configured. If the
		user installs and configures the C++ standard library, this
		example will compile the demos using it.
