Hello Team,
I hope you are well and good .
While I am doing the compilation of osmocom BB , There are errors as following , I committed the "Hello world" in the Makefile then there was another error and it kept coming one after another after I did the commit .
Please note I have installed all the pre-requisites , GnuARM ToolChain and Libsomocomcore as directed in document . Also I have tried on both Ubuntu 20 and 22 but still the error keep coming .
Please let me know for any know solutions for the same and also let me know if you need some more information from myside .
Advance thanks for your support and all this good work .

Please try reverting this commit:

It was reported by several other people that this commit breaks the firmware builds when using the old "arm-elf-*" toolchain.

Many Thanks for your reply Vadim,
I reverted the suggested commit and now getting the below error

Also you mentioned that people are getting this error while using the old "arm-elf-*" Toolchain, May you please guide me on where I can get the new Toolchain ? So I do need to make these reverts .
Currently I am following the OSMOCOM Guide and installing the toolchain as mentioned below .
sudo apt install gcc-arm-none-eabi

interestingly enough, this is exactly the error that the commit I suggested to revert is supposed to fix. I was getting this error with arm-none-eabi-gcc v13.2.0 and that commit fixed the problem for me.
As a temporary workaround, in addition to having the Harald's commit reverted, I suggest applying this patch:
--- a/src/target/firmware/Makefile.inc +++ b/src/target/firmware/Makefile.inc @@ -22,7 +22,7 @@ CFLAGS += -g$(DEBUGF) #ASFLAGS=--g$(DEBUGF) $(INCLUDES) -D__ASSEMBLY__ ASFLAGS=$(INCLUDES) -D__ASSEMBLY__
-LDFLAGS = -nostartfiles -nostdlib -nodefaultlibs --gc-sections --cref +LDFLAGS = -nostdlib -z nodefaultlib --gc-sections --cref
#### QUIET OUTPUT ####
This is how I used to workaround the problem when building locally, before the Harald's patch was merged.
Also you mentioned that people are getting this error while using the old "arm-elf-*" Toolchain, May you please guide me on where I can get the new Toolchain ? So I do need to make these reverts .
It appears like you're already using a more or less recent toolchain. But we would need to know the version, of course ;) I thought were using arm-none-eabi-gcc v4.8.2.
Currently I am following the OSMOCOM Guide and installing the toolchain as mentioned below .
sudo apt install gcc-arm-none-eabi
Please tell us the exact version(s) of the toolchain components:
$ dpkg -l | grep arm-none-eabi
And what kind of linux distribution you're using (Debian? Ubuntu?).
I just gave it a try in docker, using debian:bookworm image:
root@a2fb7cb6978c:/osmocom-bb/src# dpkg -l | grep arm-none-eabi ii binutils-arm-none-eabi 2.40-2+18+b1 amd64 ii gcc-arm-none-eabi 15:12.2.rel1-1 amd64 ii libnewlib-arm-none-eabi 3.3.0-1.3 all ii libstdc++-arm-none-eabi-dev 15:12.2.rel1-1+23 all ii libstdc++-arm-none-eabi-newlib 15:12.2.rel1-1+23 all
And could successfully build the firmware without having to revert anything.
Many Thanks Vadim for your reply , I am getting the new error now .

Hello Neeraj,
I managed to reproduce the problem in a Docker container using ubuntu:jammy (22.04.4 LTS) as the base image. Doing what I suggested in a previous mail fixes build errors, so please carefully check if you followed my recommendations closely enough.
Below is the Dockerfile I used for testing, including the workaround:
------------------------------------------------------------------
FROM ubuntu:jammy
RUN apt-get update && \ apt-get install -y --no-install-recommends \ autoconf automake libtool \ build-essential \ gcc-arm-none-eabi \ libnewlib-arm-none-eabi \ ca-certificates \ python3 git
WORKDIR /root
RUN git clone https://git.osmocom.org/osmocom-bb
# workaround for the ARM toolchain provided by Ubuntu 22.04.4 # ii binutils-arm-none-eabi 2.40-2+18+b1 # ii gcc-arm-none-eabi 15:12.2.rel1-1 RUN cd osmocom-bb/ && \ git config --global user.email "you@example.com" && \ git revert --no-edit 818133cd23b493da472daff2cda9a8e97d0c9637 && \ sed -i "/DCONFIG_TX_ENABLE/c\CFLAGS += -DCONFIG_TX_ENABLE" \ src/target/firmware/Makefile && \ sed -i "/LDFLAGS =/c\LDFLAGS = -nostdlib -z nodefaultlib --gc-sections --cref" \ src/target/firmware/Makefile.inc
RUN cd osmocom-bb/src/ && make firmware
------------------------------------------------------------------
I don't think there is anything we can do to support the variety of toolchain variants/versions. We're using 'debian:bookworm' Docker image for the build verification, so I would suggest to use it too. We also have a Dockerfile for building the old toolchain:
https://cgit.osmocom.org/docker-playground/tree/arm-none-eabi-gcc-4.8.2
