config EXAMPLES_ELF
bool "ELF Loader Example"
default n
select LIBC_EXECFUNCS
---help---
Enable the ELF loader example
if EXAMPLES_ELF
config EXAMPLES_ELF_SYSCALL
bool "Link with SYSCALL library"
default n
depends on LIB_SYSCALL && !BUILD_KERNEL
---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
depends on !BUILD_KERNEL
---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 SYSCALL library and will interface with the OS
system calls. 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_DEVMINOR
int "ROMFS Minor Device Number"
default 0
---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 "ROMFS Device Path"
default "/dev/ram0"
---help---
The path to the ROMFS block driver device. This must match EXAMPLES_ELF_DEVMINOR.
Used for registering the RAM block driver that will hold the ROMFS file system
containing the ELF executables to be tested. Default: "/dev/ram0"
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.
