Newlib cross-compiling issue
Posted: Sun Dec 11, 2016 3:11 pm
Good day!
I'm trying to compile Newlib for STM32F4DISCOVERY. My system is Ubuntu 14.04 x86_64, my toolchain is GNU ARM Embedded toolchain (so compiler is arm-none-eabi-gcc).
How do I configure and compile? Show me a command, please?
(Sure) I've done some actions but they are all unsuccessful. Most often cases (while playing with --target, --host, --build) are:

Thanks!

(Sure) I've done some actions but they are all unsuccessful. Most often cases (while playing with --target, --host, --build) are:
- unrecognized target machine,
- host compiler is used instead of target while "compiler checking" (and it doesn't recognize ARM-specific options),
- (target compiler is used and) executable format error.
