# Memgraph Toolchain v$TOOLCHAIN_VERSION

## Included tools

 - GCC $GCC_VERSION
 - Binutils $BINUTILS_VERSION
 - GDB $GDB_VERSION
 - CMake $CMAKE_VERSION
 - Cppcheck $CPPCHECK_VERSION
 - LLVM (Clang, LLD, compiler-rt, Clang tools extra) $LLVM_VERSION

## Required libraries

In order to be able to run all of these tools you should install the following
packages:

\`\`\`
$($DIR/../../os/$ENV_SCRIPT.sh list TOOLCHAIN_RUN_DEPS)
\`\`\`

## Usage

In order to use the toolchain you just have to source the activation script:

\`\`\`
source $PREFIX/activate
\`\`\`
