bool "External File system"
|
|
---help---
|
|
The file system is assumed to reside on some external media
|
|
such as an SD card or a USB FLASH drive. In this case, that
|
|
external file system must be created manually by copying the
|
|
files in apps/examples/elf/tests/romfs to the volume.
|
|
|
|
The external volume can optionally be mounted by the test if
|
|
the CONFIG_EXAMPLES_FSMOUNT option is also selected.

If the external file system is on removable media such as an
|
|
SD card or a USB FLASH driver, then this option may be selected
|
|
to build in logic to wait for the media to be installed and
|
|
initialized before trying to mount it.

---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

string "External file system type"

---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_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.
