Testing LLVM LIBC++ with NuttX
|
||||
==============================
|
||||
|
||||
You can use LLVM LIBC++ on NuttX to get a C++ compiler with C++11 features.
|
||||
Follow these steps to get it working:
|
||||
|
||||
Clone the needed repositories:
|
||||
|
||||
$ git clone https://www.bitbucket.org/acassis/libcxx
|
||||
|
||||
$ git clone https://www.bitbucket.org/nuttx/apps
|
||||
|
||||
$ git clone https://www.bitbucket.org/nuttx/nuttx
|
||||
|
||||
Install the libcxx files on NuttX:
|
||||
|
||||
$ cd libcxx
|
||||
|
||||
$ ./install.sh ../nuttx
|
||||
Installing LLVM/libcxx in the NuttX source tree
|
||||
Installation suceeded
|
||||
|
||||
Enter inside NuttX and compile it:
|
||||
|
||||
$ cd ../nuttx
|
||||
|
||||
$ ./tools/configure.sh stm32f4discovery/testlibcxx
|
||||
Copy files
|
||||
Refreshing...
|
||||
|
||||
$ ls -l nuttx.bin
|
||||
-rwxrwxr-x 1 alan alan 58112 Ago 8 11:08 nuttx.bin
|
||||
|
||||
Plug the MiniUSB cable in the STM32F4Discovery board and flash the firmware:
|
||||
|
||||
$ sudo openocd -f interface/stlink-v2.cfg -f target/stm32f4x.cfg -c init \
|
||||
-c "reset halt" -c "flash write_image erase nuttx.bin 0x08000000"
|
||||
|
||||
...
|
||||
|
||||
Info : device id = 0x10036413
|
||||
Info : flash size = 1024kbytes
|
||||
target halted due to breakpoint, current mode: Thread
|
||||
xPSR: 0x61000000 pc: 0x20000046 msp: 0x20001d60
|
||||
wrote 65536 bytes from file nuttx.bin in 2.959432s (21.626 KiB/s)
|
||||
|
||||
Connect the USB/Serial 3.3V dongle to PA2(board TX) and PA3(board RX) use
|
||||
minicom or other serial console configured to 115200 8n1.
|
||||
|
||||
Press Reset pin of the board and you will see:

||||

Builtin Apps:

helloxx
|

|

nsh>
|
||||
|
||||
|
||||
Just type helloxx:
|

|
||||
nsh> helloxx
|
||||
helloxx_main: Saying hello from the dynamically constructed instance
|
||||
CHelloWorld::HelloWorld: Hello, World!!
|
||||
helloxx_main: Saying hello from the instance constructed on the stack
|
||||
CHelloWorld::HelloWorld: Hello, World!!
|
||||
helloxx_main: Saying hello from the statically constructed instance
|
||||
CHelloWorld::HelloWorld: Hello, World!!
|
