Subject: travis-ci: Build C/C++/Python matrix
X-Git-Tag: 5.0.2~186^2~110^2~1
X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?a=commitdiff_plain;h=47bd244f2e7772c2259f2c37ddf9480959c2272a;p=apps%2Fagl-service-can-low-level.git

travis-ci: Build C/C++/Python matrix

* Test a number of C compilers
* Travis CI can't handle three languages (C, C++, Python)
* Add support for swapping python2/3 binaries
* Scons has made no attempts to support python3 yet:
* Build the matrix manually
* Scons doesn't inherit $CC/$CXX from parent environement,
  so pass compiler flags directly
