# Memgraph Toolchain v$TOOLCHAIN_VERSION

## Included tools

 - GCC $GCC_VERSION
 - Binutils $BINUTILS_VERSION
 - GDB $GDB_VERSION
 - CMake $CMAKE_VERSION
 - Cppcheck $CPPCHECK_VERSION
 - LLVM (clang;clang-tools-extra;compiler-rt;libunwind;lldb[;libcxx;libcxxabi]) $LLVM_VERSION

## Required libraries

In order to be able to run all of these tools you should install the following
packages:
\`\`\`
./$ENV_SCRIPT_RELATIVE list TOOLCHAIN_RUN_DEPS)
\`\`\`
by executing:
\`\`\`
./$ENV_SCRIPT_RELATIVE install TOOLCHAIN_RUN_DEPS)
\`\`\`

## Usage

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

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

On the other hand, \`deactivate\` will get back your original setup by restoring
the initial environment variables.
