prompt "Application build type"
default APP_BUILD_TYPE_APP_2NDBOOT
help
Select the way the application is built.
By default, the application is built as a binary file in a format compatible with
the ESP-IDF bootloader. In addition to this application, 2nd stage bootloader is
also built. Application and bootloader binaries can be written into flash and
loaded/executed from there.
Another option, useful for only very small and limited applications, is to only link
the .elf file of the application, such that it can be loaded directly into RAM over
JTAG. Note that since IRAM and DRAM sizes are very limited, it is not possible to
build any complex application this way. However for kinds of testing and debugging,
this option may provide faster iterations, since the application does not need to be
written into flash.
Note that at the moment, ESP-IDF does not contain all the startup code required to
initialize the CPUs and ROM memory (data/bss). Therefore it is necessary to execute
a bit of ROM code prior to executing the application. A gdbinit file may look as follows (for ESP32):
# Connect to a running instance of OpenOCD
target remote :3333
# Reset and halt the target
mon reset halt
# Run to a specific point in ROM code,
# where most of initialization is complete.
thb *0x40007d54
c
# Load the application into RAM
load
# Run till app_main
tb app_main
c
Execute this gdbinit file as follows:
xtensa-esp32-elf-gdb build/app-name.elf -x gdbinit
Example gdbinit files for other targets can be found in tools/test_apps/system/gdb_loadable_elf/
Recommended sdkconfig.defaults for building loadable ELF files is as follows.
CONFIG_APP_BUILD_TYPE_ELF_RAM is required, other options help reduce application
memory footprint.

default COMPILER_OPTIMIZATION_DEFAULT
help
This option sets compiler optimization level (gcc -O argument) for the app.
- The "Default" setting will add the -0g flag to CFLAGS.
- The "Size" setting will add the -0s flag to CFLAGS.
- The "Performance" setting will add the -O2 flag to CFLAGS.
- The "None" setting will add the -O0 flag to CFLAGS.
The "Size" setting cause the compiled code to be smaller and faster, but
may lead to difficulties of correlating code addresses to source file
lines when debugging.
The "Performance" setting causes the compiled code to be larger and faster,
but will be easier to correlated code addresses to source file lines.
"None" with -O0 produces compiled code without optimization.
Note that custom optimization levels may be unsupported.
Compiler optimization for the IDF bootloader is set separately,
see the BOOTLOADER_COMPILER_OPTIMIZATION setting.

Assertions can be:

- Set to "silent" to save code size (failed assertions will abort() but user
needs to use the aborting address to find the line number with the failed assertion.)
- Disabled entirely (not recommended for most configurations.) -DNDEBUG is added
to CPPFLAGS in this case.

menuconfig COMPILER_HIDE_PATHS_MACROS
bool "Replace ESP-IDF and project paths in binaries"
default y
help
When expanding the __FILE__ and __BASE_FILE__ macros, replace paths inside ESP-IDF
with paths relative to the placeholder string "IDF", and convert paths inside the
project directory to relative paths.
This allows building the project with assertions or other code that embeds file paths,
without the binary containing the exact path to the IDF or project directories.
This option passes -fmacro-prefix-map options to the GCC command line. To replace additional
paths in your binaries, modify the project CMakeLists.txt file to pass custom -fmacro-prefix-map or
-ffile-prefix-map arguments.
menuconfig COMPILER_CXX_EXCEPTIONS
bool "Enable C++ exceptions"
default n
help
Enabling this option compiles all IDF C++ files with exception support enabled.
Disabling this option disables C++ exception support in all compiled files, and any libstdc++ code
which throws an exception will abort instead.
Enabling this option currently adds an additional ~500 bytes of heap overhead
when an exception is thrown in user code for the first time.
config COMPILER_CXX_EXCEPTIONS_EMG_POOL_SIZE
int "Emergency Pool Size"

Size (in bytes) of the emergency memory pool for C++ exceptions. This pool will be used to allocate
memory for thrown exceptions when there is not enough memory on the heap.
config COMPILER_CXX_RTTI
bool "Enable C++ run-time type info (RTTI)"

help
Enabling this option compiles all C++ files with RTTI support enabled.
This increases binary size (typically by tens of kB) but allows using
dynamic_cast conversion and typeid operator.
choice COMPILER_STACK_CHECK_MODE
prompt "Stack smashing protection mode"
default COMPILER_STACK_CHECK_MODE_NONE
help
Stack smashing protection mode. Emit extra code to check for buffer overflows, such as stack
smashing attacks. This is done by adding a guard variable to functions with vulnerable objects.
The guards are initialized when a function is entered and then checked when the function exits.
If a guard check fails, program is halted. Protection has the following modes:
- In NORMAL mode (GCC flag: -fstack-protector) only functions that call alloca, and functions with
buffers larger than 8 bytes are protected.
- STRONG mode (GCC flag: -fstack-protector-strong) is like NORMAL, but includes additional functions
to be protected -- those that have local array definitions, or have references to local frame
addresses.
- In OVERALL mode (GCC flag: -fstack-protector-all) all functions are protected.
Modes have the following impact on code performance and coverage:
- performance: NORMAL > STRONG > OVERALL
- coverage: NORMAL < STRONG < OVERALL
The performance impact includes increasing the amount of stack memory required for each task.

config COMPILER_WARN_WRITE_STRINGS
bool "Enable -Wwrite-strings warning flag"
default "n"
help
Adds -Wwrite-strings flag for the C/C++ compilers.
For C, this gives string constants the type ``const char[]`` so that
copying the address of one into a non-const ``char *`` pointer
produces a warning. This warning helps to find at compile time code
that tries to write into a string constant.
For C++, this warns about the deprecated conversion from string
literals to ``char *``.
config COMPILER_SAVE_RESTORE_LIBCALLS
bool "Enable -msave-restore flag to reduce code size"
depends on IDF_TARGET_ARCH_RISCV
help
Adds -msave-restore to C/C++ compilation flags.
When this flag is enabled, compiler will call library functions to
save/restore registers in function prologues/epilogues. This results
in lower overall code size, at the expense of slightly reduced performance.
This option can be enabled for RISC-V targets only.
config COMPILER_DISABLE_GCC8_WARNINGS
bool "Disable new warnings introduced in GCC 6 - 8"
default "n"
help
Enable this option if using GCC 6 or newer, and wanting to disable warnings which don't appear with
GCC 5.
config COMPILER_DUMP_RTL_FILES
bool "Dump RTL files during compilation"
help
If enabled, RTL files will be produced during compilation. These files
can be used by other tools, for example to calculate call graphs.
