GCC toolchain version for SDK 17.0.2 on posix

[Charlie]

I was wondering if I could clarify the GCC version which is suggested for use with SDK 17.0.2.

In the release notes, it states:

The following toolchains/devices have been used for testing and verification:
...
 - GCC: GCC ARM Embedded 9.2019q4.major

However in components/toolchain/gcc/Makefile.posix, it's configured as follows:

GNU_INSTALL_ROOT ?= /usr/local/gcc-arm-none-eabi-7-2018-q2-update/bin/
GNU_VERSION ?= 7.3.1
GNU_PREFIX ?= arm-none-eabi

Makefile.windows in the same directory appears to use "9 2019-q4-major".

Is this a mistake in Makefile.posix, or is something else going on here?

Hi,

This looks strange to me. I would expect 9-2019-q4 to be used for posix as well. I have asked the developers for feedback and will get back to you.

Hi Terje,

Any news on this? I've been using the 9.2019q4 version with SDK17.0.2 with no issues so far.

Hi,

I had not heard back from the developers, so I asked again, and they will look into why the makefiles are the way that they are. From what we can tell at the moment, though, 9.2019q4 is the preferred version for all platforms.

Hi,

I can confirm this is a bug. The correct should be:

GNU_INSTALL_ROOT ?= /usr/local/gcc-arm-none-eabi-9-2019-q4-major/bin/
GNU_VERSION ?= 9.2.1
GNU_PREFIX ?= arm-none-eabi
