Installation of various common packages

Task 1: GCC

1. Install Build environment

   [root@master ~]# yum groupinstall "Development Tools"
   

2. Compile GCC

   [install@master ~]$ wget https://ftp.lip6.fr/pub/gcc/releases/gcc-8.3.0/gcc-8.3.0.tar.gz
   [install@master ~]$ tar xvzf gcc-8.3.0.tar.gz
   [install@master ~]$ cd gcc-8.3.0
   [install@master gcc-8.3.0]$ ./contrib/download_prerequisites
   [install@master gcc-8.3.0]$ cd ..
   

   Create build folder

   [install@master ~]$ mkdir build-gcc-8.3.0
   [install@master ~]$ cd build-gcc-8.3.0
   

   Configure GCC (without 32bit support)

   [install@master build-gcc-8.3.0]$ ../gcc-8.3.0/configure --prefix=/data/opt/tools/gcc-8.3.0 --disable-multilib
   

   Compile in parallel; this will take some time, so do next tasks in the meantime

   [install@master build-gcc-8.3.0]$ make -j 4
   

3. Install GCC

   [install@master build-gcc-8.3.0]$ make install
   

4. Create Modulefile for GCC

   • create the file /data/opt/tools/modulesfiles/gcc/8.3.0.lua

Task 2: CMake

1. Download binary distribution from CMake

   [install@master ~]$  wget https://github.com/Kitware/CMake/releases/download/v3.14.1/cmake-3.14.1-Linux-x86_64.tar.gz
   

2. Unpack binary release in /data/opt/tools/cmake-3.14.1

3. Create Modulefile /data/opt/tools/modulefiles/cmake/3.14.1.lua

Bonus Task: Installing Clang

Building clang usually requires a rather current toolchain. Use your new GCC module and CMake module to compile and install it.

1. Download LLVM and Clang via Git

   [install@master ~]$ git clone https://github.com/llvm/llvm-project.git
   [install@master ~]$ cd llvm-project
   [install@master llvm-project]$ mkdir build
   [install@master llvm-project]$ cd build
   

2. Build and install LLVM and Clang

   [install@master build]$ export GCC_HOME=/data/opt/tools/gcc-8.3.0
   [install@master build]$ export CC=$GCC_HOME/bin/gcc
   [install@master build]$ export CXX=$GCC_HOME/bin/g++
   [install@master build]$ cmake -D CMAKE_CXX_LINK_FLAGS="-Wl,-rpath,$GCC_HOME/lib64 -L$GCC_HOME/lib64" \
                           -D CMAKE_INSTALL_PREFIX=/data/opt/tools/clang-8.0.0 \
                           -D LLVM_ENABLE_PROJECTS=clang \
                           -D CMAKE_BUILD_TYPE=Release \
                           ../llvm
   [install@master build]$ make -j 4
   [install@master build]$ make install
   

3. Create Modulefile /data/opt/tools/modulefiles/clang/8.0.0.lua
