Misconfigured environment

[KozhinovAlexander]

Building on of the existing examples leads to misconfigured environment error.

Steps to reproduce on mac OS X 10.15.4:

1. Checkout master using tutorial Getting Started Guide
   ( in my case: West version: v0.7.2 and master of Zephyr's project )

2. Run build of an existing example project:
   west build -b nucleo_l432kc samples/hello_world

3. Get the error:

Obviously the error is in environment variable:

CROSS_COMPILE: /usr/local/bin/bin/arm-none-eabi-

Following temporar fix works for me:

In the file:

/Users/<your_user_name_here>/Documents/DevProjects/zephyrproject/zephyr/cmake/compiler/gcc/generic.cmake

add following command:

set(CROSS_COMPILE "/usr/local/bin/arm-none-eabi-")

@Nukersson is your GNU Arm Embedded toolchain installed in /usr/local/bin ? We don't support generic installations of GNU Arm Embedded (like the one from Homebrew), you need to download it manually from:

https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm

and then install it in a fixed directory and point to it via the GNUARMEMB_TOOLCHAIN_PATH environment variable.

[KozhinovAlexander]

is your GNU Arm Embedded toolchain installed in /usr/local/bin ?
Yes it is.
But what I am confused of is:

CROSS_COMPILE: /usr/local/bin/bin/arm-none-eabi-
has bin twice while TOOLCHAIN_HOME: /usr/local/bin. How can it be?

[carlescufi]

@Nukersson how did you install GNU Arm Embedded?

[KozhinovAlexander]

My GNU Arm Embedded environment installed according to toolchain-gnuarmemb

P.S: I've updated west/zephyr today and the behavior is no more there.

Thanks, will close the issue then.

HI I have the same issue.

[Alex-EEE]

CROSS_COMPILE: /Users/alex/toolchains/arm/bin/bin/arm-none-eabi-

Why is it bin/bin?

[KozhinovAlexander]

CROSS_COMPILE: /Users/alex/toolchains/arm/bin/bin/arm-none-eabi-

Why is it bin/bin?

I think, It is fixed already. Thus it can not be, that it not works for you. I've installed completely new Ubuntu 20.04 virtual machine with latest Zephyr toolchain like it done in corresponding Docker file @ line 111 about a month ago and it worked nicely for me.

P.S.: please read some of my posts above - there I explained, why bin/bin is a mistake.

Hi,

Here are my env vars:
(dsp-quantized-too-big-fix) benchmark-fw $ echo $GNUARMEMB_TOOLCHAIN_PATH
/Users/alex/toolchains/arm

Is there some way to reset any cached things in the build system? I did have a different env var at the start. Here is the full output, showing the vesrion of Zephry

(dsp-quantized-too-big-fix) benchmark-fw $ ZEPHYR_BASE=~/work/tool-repos/zephyr/zephyr/ west build -p auto -b stm32f4_disco .

The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

Ok, I figured it out. If you need to change your toolchain path (GNUARMEMB_TOOLCHAIN_PATH) you need to delete your build folder first. Otherwise, west uses some cached copy of that path

It is always a very good idea to remove your build folder after each toolchain / west update and / or git pull.

[WayneKeenan]

It's not just a good idea, it is necessary, I hit this issue after a clean Docker image install/update then project compile, it was only eventually resolved by removing the build folder.

Fixed by setting GNUARMEMB_TOOLCHAIN_PATH=/opt/homebrew, as my toolchain was installed through homebrew.
