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:
- 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.
CFLAGS I add:
Code: Select all
-DPREFER_SIZE_OVER_SPEED -mfloat-abi=softfp -mcpu=cortex-m4 -mthumb
Switches I add:
Code: Select all
--disable-libquadmath --disable-libquadmath-support --disable-libstdcxx --disable-newlib-fvwrite-in-streamio --disable-newlib-fseek-optimization --disable-newlib-wide-orient --disable-newlib-unbuf-stream-opt --disable-multilib --disable-newlib-multithread --disable-newlib-io-float --disable-newlib-supplied-syscalls
Thanks!
