Unfortunately the building of SST (in "ext/sst") depends on generated header files. Therefore it adds the build directory to the include path. For this to work the libgem5.so must be build with "--duplicate-sources".

# Installing SST
|
|
|
|
The links to download SST source code are available here
|
|
[http://sst-simulator.org/SSTPages/SSTMainDownloads/].
|
|
This guide is using the most recent SST version (11.0.0) as of September 2021.
|
|
The following guide assumes `$SST_CORE_HOME` as the location where SST will be
|
|
installed.
|
|
|
|
## SST-Core
|
|
|
|
### Downloading the SST-Core Source Code
|
|
|
|
```sh
|
|
wget https://github.com/sstsimulator/sst-core/releases/download/v11.1.0_Final/sstcore-11.1.0.tar.gz
|
|
tar xf sstcore-11.1.0.tar.gz
|
|
```
|
|
|
|
### Installing SST-Core
|
|
|
|
```sh
|
|
cd sstcore-11.1.0
|
|
./configure --prefix=$SST_CORE_HOME --with-python=/usr/bin/python3-config \
|
|
--disable-mpi # optional, used when MPI is not available.
|
|
make all -j$(nproc)
|
|
make install
|
|
```
|
|
|
|
Update `PATH`,
|
|
|
|
```sh
|
|
export PATH=$SST_CORE_HOME/bin:$PATH
|
|
```
|
|
|
|
## SST-Elements
|
|
|
|
### Downloading the SST-Elements Source Code
|
|
|
|
```sh
|
|
wget https://github.com/sstsimulator/sst-elements/releases/download/v11.1.0_Final/sstelements-11.1.0.tar.gz
|
|
tar xf sstelements-11.1.0.tar.gz
|
|
```
|
|
|
|
### Installing SST-Elements
|
|
|
|
```sh
|
|
cd sst-elements-library-11.1.0
|
|
./configure --prefix=$SST_CORE_HOME --with-python=/usr/bin/python3-config \
|
|
--with-sst-core=$SST_CORE_HOME
|
|
make all -j$(nproc)
|
|
make install
|
|
```
|
|
|
|
Adding `PKG_CONFIG_PATH` to `.bashrc` (so pkg-config can find SST .pc file),
|
|
|
|
```sh
|
|
echo "export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$SST_CORE_HOME/lib/pkgconfig/" >> ~/.bashrc
|
|
```
|
|
|
|
### Building gem5 library
|
|
|
|
At the root of gem5 folder,
|
|
|
|
```sh
|
|
scons build/RISCV/libgem5_opt.so -j $(nproc) --without-tcmalloc --duplicate-sources
|
|
```
|
|
|
|
**Note:** `--without-tcmalloc` is required to avoid a conflict with SST's malloc.
|
|
`--duplicate-sources` is required as the compilation of SST depends on sources to be present in the "build" directory.
|
|
|
|
### Compiling the SST integration
|
|
|
|
At the root of gem5 folder,
|
|
|
|
```sh
|
|
cd ext/sst
|
|
make
|
|
```
|
|
|
|
