13449,"Execution of boost_mpl_preprocess.py fails if $(boost_root) path contains the string ""linux""",Mihai Pop <mihaipop11@…>,Aleksey Gurtovoy,"**How to reproduce:**

Build System: Ubuntu 16.04.0 LTS
GCC: all

Let's say that we have the boost sources in `/tmp/boost-linux/boost_1_X_X`

The important thing is to have the string `linux` in the `boost-root` variable.

**Error log:**

**Problem:**
This appears because in `preprocess.cmd` gcc is invoked with include files included with angle brackets, so if we have the string `linux` it will be evaluated to `1` because it is a macro
