^^^^^^^^^^^^^^^

This example builds a small shared library module test case. The test
|
||||
shared library is built using the relocatable ELF format and installed
|
||||
in a ROMFS file system. At run time, the shared library is installed and exercised. Requires CONFIG_LIBC_DLLFCN. Other configuration options:
|
||||
|
||||
CONFIG_EXAMPLES_SOTEST_DEVMINOR - The minor device number of the ROMFS block
|
||||
driver. 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_SOTEST_DEVPATH - 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"
|
||||
|
||||
NOTES:
|
||||
|
||||
1. CFLAGS should be provided in CMODULEFLAGS. RAM and FLASH memory regions
|
||||
may require long allcs. For ARM, this might be:
|
||||
|
||||
CMODULEFLAGS = $(CFLAGS) -mlong-calls
|
||||
|
||||
Similarly for C++ flags which must be provided in CXXMODULEFLAGS.
|

|

2. Your top-level nuttx/Make.defs file must also include an approproate definition,

LDMODULEFLAGS, to generate a relocatable ELF object. With GNU LD, this should
|
||||
include '-r' and '-e <entry point>'.
|
||||
|
||||
LDMODULEFLAGS = -r -e module_initialize
|
||||
|
||||
If you use GCC to link, you make also need to include '-nostdlib' or
|
||||
'-nostartfiles' and '-nodefaultlibs'.
|
||||
|
||||
3. This example also requires genromfs. genromfs can be build as part of the
|
||||
nuttx toolchain. Or can built from the genromfs sources that can be found
|
||||
in the NuttX tools repository (genromfs-0.5.2.tar.gz). In any event, the
|
||||
PATH variable must include the path to the genromfs executable.
|
||||
|
||||
4. ELF size: The ELF files in this example are, be default, quite large
|
||||
because they include a lot of "build garbage". You can greatly reduce the
|
||||
size of the ELF binaries are using the 'objcopy --strip-unneeded' command to
|
||||
remove un-necessary information from the ELF files.
|
||||
|
||||
5. Simulator. You cannot use this example with the the NuttX simulator on
|
||||
Cygwin. That is because the Cygwin GCC does not generate ELF file but
|
||||
rather some Windows-native binary format.
|
||||
|
||||
If you really want to do this, you can create a NuttX x86 buildroot toolchain
|
||||
and use that be build the ELF executables for the ROMFS file system.
|
||||
|
||||
6. Linker scripts. You might also want to use a linker scripts to combine
|
||||
sections better. An example linker script is at nuttx/sched/module/gnu-elf.ld.
|
||||
That example might have to be tuned for your particular linker output to
|
||||
position additional sections correctly. The GNU LD LDMODULEFLAGS then might

||||
be:

By default, all undefined symbols must be provided via a symbol

table. But if this option is selected, then each SOTEST 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.
