Hello,

We have an R package with a lot of dependencies. We use Travis-CI’s build caching, which generally really helps this and makes builds very fast. However, we recently had to clear our cache and have been hitting a lot of problem, including that our build log file exceeds the limit of 4mb. I googled this and ended up setting “CXXFLAGS=$CXXFLAGS -w -DEIGEN\_PERMANENTLY\_DISABLE\_STUPID\_WARNINGS” in $HOME/.R/Makevars. This might be helping, but many RcppEigen-related commands dont inherit this and these blocks in particular log a huge amount of text. Has anyone else experienced this, and/or do you have ideas on debugging?

RcppEigen 0.3.3.7.0 gets installed from CRAN. Thanks in advance.

One example output is here:

[https://api.travis-ci.com/v3/job/379691434/log.txt](https://api.travis-ci.com/v3/job/379691434/log.txt)

the first few lines of an example are:

+1 for me. Did you come up with a good solution for this? Thank you, Greg.
