RISC-v emulator

Changes are based on https://risc-v-getting-started-guide.readthedocs.io/en/latest/linux-qemu.html

For Ubuntu/Debian, in addition to

sudo apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev \
                 gawk build-essential bison flex texinfo gperf libtool patchutils bc \
                 zlib1g-dev libexpat-dev git

You will need the development headers for

sudo apt-get install libglib2.0-dev libpixman-1-dev libncurses-dev


Before building Busybear Linux, you will need to softlink riscv-pk into busy bear-linux because git checkout put riscv-pk into the riscv64-linux.

cd riscv64-linux/busybear-linux

rm -rf src/riscv-pk

ln -s ../riscv-pk src/

You need to enable the following modules within .config in the linux folder.

CONFIG_E100=y

CONFIG_E1000=y

CONFIG_E1000E=y

Start the QEMU emulator with the following command:

  sudo qemu-system-riscv64 \

        -nographic \

        -machine virt \

        -kernel riscv-pk/build/bbl \

        -append "root=/dev/vda ro console=ttyS0" \

        -drive file=busybear-linux/busybear.bin,format=raw,id=hd0 \

        -device virtio-blk-device,drive=hd0 \

        -netdev type=tap,script=./ifup,downscript=./ifdown,id=net0 \

        -device virtio-net-device,netdev=net0

Hyperledger Problems and Fixes

Problem 1: 
Error: got unexpected status: BAD_REQUEST -- error validating channel creation transaction for new channel 'carsales', could not successfully apply update to template configuration: error authorizing update: error validating DeltaSet: policy for [Group]  /Channel/Application not satisfied: implicit policy evaluation failed - 0 sub-policies were satisfied, but this policy requires 1 of the 'Admins' sub-policies to be satisfied

Solution: 

Remove old channel, chaincode, and other information

$> sudo rm -rf /var/hyperledger

Then, restart all services so that information in the above folder will be recreated. E.g.,

Restart orderer
$> sudo systemctl start fabric-orderer.service

Restart peer
$> sudo systemctl start fabric-peer0-org1.service



Problem 2:
My peer nodes are behind a firewall. The docker container created for building the chaincode cannot resolve URL.

When running peer chaincode instantiate ..., I got

collect2: error: ld returned 1 exit status

This is caused by the installation of the old flint library. Typically done by apt-get install. 

So get remove the error, you need to run

$> sudo apt-get remove libflint-dev

then soft symlink the flint.h to the /usr/local/include/ by this command

$> sudo ln -s /usr/local/include/flint/flint.h /usr/local/include/flint.h

LD_LIBRARY_PATH=/usr/local/lib
export LD_LIBRARY_PATH

then it should work.

NTL library: symbol(s) not found for architecture x86_64

It took me a few days to resolve this problem with the NTL library on Mac OS X.

http://www.shoup.net/ntl/doc/tour-unix.html

So I am going to share the solution with anyone who might run into this problem.

The error:

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Because Mac OS X now using libc++ rather than libstdc++, so you will need to compile the NTL library with libc++. You have to force it to use the libc++ option. The new compiling steps:

1. ./configure  NTL_GMP_LIP=on

2. open makefile under src/ and change to the following

CXX=clang++

# A C++ compiler, e.g., g++, CC, xlC 

LDLIBS=-lm -lc++

# libraries for linking C++ programs

3. make & sudo make install

Then you should be able to use the NTL library natively in Mac OS X.
