# Description

It seems the export of compiler variable name is ill-formed i.e. it uses `["gcc"]` instead of `gcc`

# Protocol

Just create a simple `.travis.yml`

```auto
sudo: false
language: cpp
matrix:
  include:
   - os: linux
      dist: trusty
      compiler:
        - gcc
...

```

# Observed

```auto
$ export TRAVIS_COMPILER=["gcc"]
$ export CXX=g++
$ export CC=gcc
$ ["gcc"] --version
[gcc]: command not found

```

My bad, when using Matrix include you must use

```auto
  include:
   - os: linux
      dist: trusty
      compiler: gcc

```

note: for `env` the interpreter simply call `export X` for each row  
e.g.

```auto
 include:
   - os: linux
      dist: trusty
      env:
        - FOO=ON
        - BAR=OFF

```

you’ll get

```auto
...
export FOO=ON
export BAR=OFF

```
