fail to make cross compiler

[JenniferBrana]

Hi,
I have been attempting to make both elf-gcc and linux-gcc. Both fail to build with the same error messages.

My environment: Ubuntu 18.04.4 LTS, GCC version: 7.5.0.

After a long compile time, I received the error below. Does anyone know how to resolve this?

Please provide full details on how your building the tools for both cases.

1. git clone command lines
2. configure command line
3. make command lines

I built both the bare metal/newlib and Linux toolchains (on Zorin OS Lite 16.2 - a Ubuntu 20.04 LTS derivative) recently (last week) with no issues.

git clone https://github.com/riscv-collab/riscv-gnu-toolchain
cd riscv-gnu-toolchain
./configure --prefix=`pwd`/newlib-installed-tools
make newlib 
make distclean
./configure --prefix=`pwd`/linux-installed-tools
make linux

My environment: Ubuntu 18.04.4 LTS, GCC version: 7.5.0.

GCC 7.5.0 is very old.

• https://gcc.gnu.org/gcc-7/

Even if it's not the cause of your problems you should probably compile the RISC-V tools with a more recent host toolchain.

[TommyMurphyTM1234]

I'm just trying my build instructions above on a clean Ubuntu 18.04 virtual machine and will post back with results as soon as I can.

[TommyMurphyTM1234]

OK - the newlib toolchain build succeeded.

I installed a fresh Ubuntu 18.04 VirtualBox virtual machine, installed all available updates, installed the VirtualBox guest additions, installed the riscv-gnu-toolchain build prerequisites plus git, and then ran the following:

cd ~/Downloads
git clone https://github.com/riscv-collab/riscv-gnu-toolchain
cd riscv-gnu-toolchain
./configure --prefix=`pwd`/newlib-installed-tools
date > make-newlib.log && make newlib 2>&1 | tee -a make-newlib.log && date >> make-newlib.log

Compressed build log: make-newlib.zip

I'll try the Linux toolchain build now.

But it looks like the issue may be with your host setup or something.

[TommyMurphyTM1234]

The Linux toolchain also built fine for me.

Compressed build log: make-linux.zip

So I cannot reproduce the issue on a clean Ubuntu 18.04 installation.

[TommyMurphyTM1234]

Invalid issue - not reproducible.
