Failing to build rv32em: "The riscv32 is not supported" #1312

Closed GlaireDaggers closed 1 year ago

GlaireDaggers commented 1 year ago

So for reference, I am attempting to build this toolchain on Linux Mint 21.1

I have followed the steps outlined in the readme. I first cloned the repository to my secondary drive, fetched the packages as given for Ubuntu, ran the following configure:

./configure --prefix=/opt/riscv --with-arch=rv32em --with-abi=ilp32e

And then did:

sudo make linux

The problem I'm running into is that this is failing in build-glibc-linux-rv32em-ilp32e, printing "checking sysdep dirs" before displaying the error "The riscv32 is not supported". The outputs of the config.log in this folder are as follows:

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by GNU C Library configure (see version.h), which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ /media/hazel/DATA[HDD]/Projects/riscv-gnu-toolchain/glibc/configure --host=riscv32-unknown-linux-gnu --prefix=/usr --disable-werror --enable-shared --enable-obsolete-rpc --with-headers=/media/hazel/DATA[HDD]/Projects/riscv-gnu-toolchain/linux-headers/include --disable-multilib --enable-kernel=3.0.0 --libdir=/usr/lib libc_cv_slibdir=/lib libc_cv_rtlddir=/lib

configure: exit 1

I'm really not sure what I'm missing here, is there some step I skipped? Any help would be appreciated.

TommyMurphyTM1234 commented 1 year ago

Anything relevant here?

GlaireDaggers commented 1 year ago

I'm seeing reference to the fact that this could happen if I somehow had the wrong glibc version checked out, but I'm not sure how that could be the case if I cloned this repo directly from master. Just in case I tried to update the glibc submodule, which had no effect. I'm currently doing a full submodule update --init --recursive as a last ditch effort to see if that helps, but ofc it's going to take a little while.

Possibly a red flag that according to one of those I'm supposed to be seeing some kind of checking for sysdeps preconfigure fragments... line, but I see nothing of the sort in the log.

TommyMurphyTM1234 commented 1 year ago

I did this on a WSL2/Ubuntu 22.04.3 installation on which I have done several toolchain builds recently:

git clone https://github.com/riscv-collab/riscv-gnu-toolchain
cd riscv-gnu-toolchain
./configure --prefix=`pwd`/installed-tools --with-arch=rv32em --with-abi=ilp32e

and I got this config.log without the error that you mention: config.log

Can you try with a new/clean Virtual Machine or other installation?

In the meantime, I've kicked off a build here:

git clone https://github.com/riscv-collab/riscv-gnu-toolchain
cd riscv-gnu-toolchain
./configure --prefix=`pwd`/installed-tools --with-arch=rv32em --with-abi=ilp32e
make linux 2>&1 | tee build.log

Possibly a red flag that according to one of those I'm supposed to be seeing some kind of checking for sysdeps preconfigure fragments... line, but I see nothing of the sort in the log.

I don't get that either so it may be outdated info.

GlaireDaggers commented 1 year ago

Hmm, strange. I guess I can try deleting it and checking it out from scratch, and then trying the same steps on my Windows box in WSL. If the latter works I guess I'll chalk it up to Linux Mint being weird.

TommyMurphyTM1234 commented 1 year ago

I can try a Linux Mint installation/build but it might be tomorrow morning (Irish time) at this stage...

Linux toolchain does not support rv32e, only bare metal toolchain support that

TommyMurphyTM1234 commented 1 year ago

Ok - but the "riscv32 is not supported" issue is arising at configuration and not make/build time.

TommyMurphyTM1234 commented 1 year ago

Ah - I misunderstood this:

The problem I'm running into is that this is failing in build-glibc-linux-rv32em-ilp32e, printing "checking sysdep dirs" before displaying the error "The riscv32 is not supported". The outputs of the config.log in this folder are as follows:

I assumed that this meant the "top level" config.log. But it seems to be a lower level config.log for glibc? In that case @kito-cheng's comment is apposite. The Linux toolchain does not suport rv32e and also requires the A (Atomic) extension.

GlaireDaggers commented 1 year ago

oooh, I see! I think I misunderstood the instructions, I do believe what I actually want is a baremetal toolchain. Sorry for the misunderstanding!

TommyMurphyTM1234 commented 1 year ago

I tried a bare-metal toolchain build and it succeeded.

git clone https://github.com/riscv-collab/riscv-gnu-toolchain issue-1312
cd issue-1312
./configure --prefix=`pwd`/installed-tools --with-arch=rv32em --with-abi=ilp32e
make 2>&1 | tee build.log
