"fatal: The remote end hung up unexpectedly" when building RISC-V 32-bit toolchain

[LucaUrbinati44]

Describe the bug I get a fatal: The remote end hung up unexpectedly when launching ./utils/toolchain/build_riscv32imc_toolchain.sh inside the esp folder, as described in the "Software toolchain" paragraph of the ESP documentation: https://www.esp.cs.columbia.edu/docs/setup/setup-guide/.

To Reproduce Steps to reproduce the behavior:

1. Just run ./utils/toolchain/build_riscv32imc_toolchain.sh inside the esp folder.

Expected behavior A clear and concise description of what you expected to happen. I'm expecting the scripts build_riscv32imc_toolchain.sh ends with: *** Successfully installed RISC-V (rv32imc) toolchain to $TARGET_DIR ***

Screenshots Screenshot of the error message:

Desktop (please complete the following information):

• OS: CentOS7
• CAD tools versions: not needed for this issue

Any suggestion to solve this issue is appreciated. Thank you

Hi Luca, please see the work around in my reply on this issue: https://github.com/sld-columbia/esp/issues/164

Hi @jzuckerman, I did as you suggested in issue #164 and it worked. However, I had to change the URLs that are reported in my previous screenshoot. Apparently, the problem is not related to ESP itself: https://lists.gnu.org/archive/html/qemu-discuss/2017-10/msg00046.html. In particular, I had to do the following operations manually (I found the new URLs by searching for the "non-working" URLs on Google):

1) Cloning https://gitlab.com/qemu-project/dtc.git https://gitlab.freedesktop.org/pixman/pixman.git into ${ESP_ROOT}/_riscv32imc_build/riscv-gnu-toolchain/riscv-qemu/.

2) Cloning https://gitlab.com/qemu-project/SLOF.git https://gitlab.com/qemu-project/ipxe.git https://gitlab.com/qemu-project/openbios.git https://gitlab.com/qemu-project/openhackware.git https://github.com/rth7680/qemu-palcode.git https://gitlab.com/qemu-project/seabios.git https://gitlab.com/qemu-project/sgabios.git https://gitlab.com/qemu-project/u-boot.git https://gitlab.com/qemu-project/vgabios.git into ${ESP_ROOT}/_riscv32imc_build/riscv-gnu-toolchain/riscv-qemu/roms/.

3) Then, I commented lines 84 and 95 of ${ESP_ROOT}/utils/toolchain/build_riscv_toolchain.sh, similarly to what is suggested in #164.

4) Rerun the script.

The strange thing is that I already installed ESP and the "riscv32imc toolchain" on another CentOS7 machine (2 months ago) and I did not encounter this issue.

I hope my contribution can help you to solve this issue. On my side, the issue can be closed. Thanks
