5 years ago Looks like the linker uses
/usr/arm-none-eabi/lib/libc_nano.a and /usr/arm-none-eabi/lib/libm.a
instead of
/usr/arm-none-eabi/lib/hard/libc_nano.a and /usr/arm-none-eabi/lib/hard/libm.a.
If I overwrite the libraries in lib/ with the libraries from lib/hard/ linking works fine.
Is this a GCC, a Fedora packaging or a modm issue?

5 years ago modm:build only specifies the modm:build:archflags once and they are then added to all relevant tool flags only once. That's all modm can do.
Then the GCC compiler uses internal configuration files called spec files, which translate the compile flags into more specific commands, for example, which libc/libm to include for what flags.
There may be an issue there (check arm-none-eabi-gcc -dumpspecs output for *multilib entries), but then again every time I sought to blame the compiler I was wrong…

5 years ago On the other hand, thumb/v7e-m+fp/hard;@mthumb@march=armv7e-m+fp@mfloat-abi=hard is what should be used for the F4 series, so why is it not?
Did they mess up the combination of using libc nano and FP?

5 years ago Also, 🤓🤓technically🤓🤓, your toolchain isn't supported by modm. #RuleLawyering
Install the ARM toochain by downloading the pre-built version for 64-bit Linux and adding its /bin directory to your path. Even though your distribution may ship their own ARM toolchain, we very strongly recommend using the official toolchain, since all of modm is tested with it.

5 years ago Could someone else using the arm-none-eabi toolchain provided by their Linux distribution be kind enough to check if they get the same bug? @ekiwi @chris-durand @mhthies @daniel-k

5 years ago Looks like Fedoras arm-none-eabi-newlib update from September 11 has fixed the issue.
When compiling a STM32F429 example on my Linux/Fedora 30 machine with GCC 9.2 I get the following error:
