Qt for STM32F417xx ARM® 32-bit Cortex®-M4 CPU GNU Tools for ARM Embedded Processors (arm-none-eabi-gcc)
-
Dear Qt for Embedded Systems developers, researchers, thinkers, support.
I.) Having STM32F417xx ARM® 32-bit Cortex®-M4 CPU based board running FreeRTOS V8.0.0:rc1 and GNU Tools for ARM Embedded Processors (arm-none-eabi-gcc) tool-chain, is it possible to install and utilize Qt 5.5 toolkit/framework of part of it for such embedded system?
The tool-chain and the system already support compilation, linking and run of C++. The build of C/C++ software for such system is done using ( makefile example ):
arm-none-eabi-g++ -mcpu=cortex-m4 -mthumb -mlittle-endian -mfloat-abi=hard -mfpu=fpv4-sp-d16 -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -fno-common -Wall -Wlogical-op -Waggregate-return -g3 -T header.ld -T section_code.ld -T section_data.ld -T trailer_code.ld -T trailer_data.ld -nostartfiles -Xlinker --gc-sections -L"W:\Freelance_projects\EMB\FromClient_\Full_Workspace_27_10_2015\Device\Sources\startup\F4" -L"W:\Freelance_projects\EMB\FromClient_\Full_Workspace_27_10_2015\STM32F4_LIB_Standard\Debug" -L"W:\Freelance_projects\EMB\FromClient_\Full_Workspace_27_10_2015\STM32_USB_Device\Debug" -Wl,-Map,"Device.map" -o "Device.elf" $(OBJS) $(USER_OBJS) $(LIBS)II.) How to integrate Qt 5.5 or a part of it for such Embedded System ?
III.) Is there already Qt 5.5 version for such embedded system ?
IV.) How to know which particular embedded system will theoretically or practically support Qt 5.5 ?
Looking forward your detailed response.
Thanks in advance,
Paul.

If you're already able to build C/C++ applications then you can just try to build Qt (it's a C++ framework written in C++ at the end).

@jsulm Thanks, you wrote:

I don't know whether it is possible (I even do not know which GCC version it is), but you can just try.
I would use the latest Qt version (5.5.1). -
It is impossible.

Thank you tomasz3dk for most correct and informative answer. To continue the mentioned thread, they say:
"FreeRTOS doesn't support POSIX, so you would need some kind of wrapper in between."
As I understand the wrapper is pure software abstraction with utilization of "underlying" hardware, in our case the hardware mentioned are connected LCD - MCU . Has anybody got an idea about such wrapper ?
Kind Regards.
