Configuration to reduce console output?

[bbimber]

We are building an R project on travis-ci with many dependencies. RcppEigen 0.3.3.7.0 is installed. The console output from anything involving RcppEigen is huge, and we're hitting limits on travis-ci with respect to log size. I googled this, and tried a few things, including setting "CXXFLAGS=$CXXFLAGS -w -DEIGEN_PERMANENTLY_DISABLE_STUPID_WARNINGS" in $HOME/.R/Makevars. These flags are passed to many g++ commands, but many dont seem to inherit this. Are there any additional config options I can set to reduce the console output from RcppEigen? Thanks in advance.

One example output is here:

https://api.travis-ci.com/v3/job/379691434/log.txt

the first few lines of an example are:

Good point. I keep a few options "locally" in ~/.R/Makevars because we are "not allowed" to set them in the src/Makevars{,.in} for reasons of "portability". CRAN has its methods and reason but sometimes you wonder...

So the quickest hack I can think of is to simple run a few lines of shell code to echo or cat into ~/.R/Makevars on your Travis account (or prepare and commit a file and just copy it in).

There is little we can do for the official package because of the CRAN Repository Policy.

@eddelbuettel so what are those lines of code?

Not claiming these are perfect for your issue but I would just add compiler flags til Boost and Eigen are quiet. They usually tell you at the end of each line what triggered them so this gives an idea:
