In the following we provide build instructions and how to compile and run software on the VP.
(Cross-)Compiling the software examples, in order to run them on the VP, requires the RISC-V GNU toolchain to be available in PATH. Several standard packages are required to build the toolchain. On Ubuntu the required packages can be installed as follows:
sudo apt-get 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
On Fedora, following actions are required:
sudo dnf install autoconf automake curl libmpc-devel mpfr-devel gmp-devel gawk bison flex texinfo gperf libtool patchutils bc zlib-devel expat-devel cmake boost-devel
sudo dnf groupinstall "C Development Tools and Libraries"
#optional debuginfo
sudo dnf debuginfo-install boost-iostreams boost-program-options boost-regex bzip2-libs glibc libgcc libicu libstdc++ zlib
For more information on prerequisites for the RISC-V GNU toolchain visit https://github.com/riscv/riscv-gnu-toolchain. With the packages installed, the toolchain can be build as follows:
git clone https://github.com/riscv/riscv-gnu-toolchain.git
cd riscv-gnu-toolchain
git submodule update --init --recursive
./configure --prefix=$(pwd)/../riscv-gnu-toolchain-dist-rv32g-ilp32d --with-arch=rv32g --with-abi=ilp32d
make
i) in vp/dependencies folder (will download and compile SystemC, and build a local version of the softfloat library):
./build_systemc_233.sh
./build_softfloat.sh
ii) in vp folder (requires the boost C++ library):
mkdir build
cd build
cmake ..
make install
The install argument is optional, it will copy all VP executables to the local vp/build/bin folder.
In sw:
cd simple-sensor # can be replaced with different example
make # (requires RISC-V GNU toolchain in PATH)
make sim # (requires *riscv-vp*, i.e. *vp/build/bin/riscv-vp*, executable in PATH)
Please note, if make is called without the install argument in step 2, then the riscv-vp executable is available in vp/build/src/platform/basic/riscv-vp.
The toplevel Makefile can alternatively be used to build the VP including its dependencies (i.e. step 2 in this README), from the toplevel folder call:
make
This will also copy the VP binaries into the vp/build/bin folder.
