### Install the required compiler on older Ubuntu versions
-If you are on an older Ubuntu version you can install a newer compiler from the `ubuntu-toolchain-r/test`-repository (with the following steps e.g. you can install GCC 10.3.0 on Ubuntu 20.04):

```bash

+sudo apt-get install g++-{{< dataFile "versions.minimum_version.gcc" 1 >}}
```
To make the newly installed compiler the default one:
```bash
-sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-10 60 \
- --slave /usr/bin/g++ g++ /usr/bin/g++-10
+sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-{{< dataFile "versions.minimum_version.gcc" 1 >}} 60 \
+ --slave /usr/bin/g++ g++ /usr/bin/g++-{{< dataFile "versions.minimum_version.gcc" 1 >}}
```
If you do not do this you have to specify the compiler during the first CMake run:
```bash
-CC=gcc-10 CXX=c++-10 cmake ../ogs [more CMake options]
+CC=gcc-{{< dataFile "versions.minimum_version.gcc" 1 >}} CXX=c++-{{< dataFile "versions.minimum_version.gcc" 1 >}} cmake ../ogs [more CMake options]
```
