build error when using --toolchain=cmake/toolchain_mcu_stm32f7.cmake
I'm building JerryScript attempting to directly run it on STM32F767, so I clone the project and then execute the command
python2 tools/build.py --toolchain=cmake/toolchain_mcu_stm32f7.cmake
Then I got an error. Log will be put under the description.
The first problem seems to be VFP problem, which can be solved by changing the content of toolchain_mcu_stm32f7.cmake from "-mfloat-abi=hard" to "-mfloat-abi=softfp". But does this affect the performance of JerryScript?
The second problem seems to be a link problem. I'm really not good at this, could anyone tell me the solution?
