'Compilation failed' error during installation

[Yiyio]

Hi,

Just wondering if anyone might know the reason for this error. I am using a pretty freshly installed ubuntu xenial 16.04 on an AWS instance (t2 micro so only 1GB of RAM). My g++ version is 5.4.0

It takes quite long before the compilation error appears.

Don't know about this particular problem, but what I faced - applications which use Eigen take a lot of ram to compile. So I was not able to compile my packages on machine with 1gb of ram. Which is pity.

[eddelbuettel]

We answered similar questions before, and also note you can get precompiled r-cran-rcppeigen from several places including the distribution itself (though possibly dated from the release) as well as current backports from Michael's PPA.

So I am closing this.

[Yiyio]

@dselivanov thanks, this turned out to be the case

[eddelbuettel]

As I said, you don't even need to as RcppEigen exists precompiled for that Ubuntu version.

And yes, C++ requires some RAM.

[dselivanov]

@eddelbuettel but still even if you have binary installation and want to build pkg which rely on RcppEigen you will face same issue, won't you? I googled quite a bit, but didn't find any solution/workaround. So for now I stick to machines/containers with 2gb+ of ram (or using prebuild container images).

[eddelbuettel]

Correct. The real issue are the Eigen (and Boost and ...) headers. But the principle holds: Michael's PPA has 3000+ packages so people who are stuck may be able to resort to binaries.
