installation issue about rcpparmadillo HOT 8 CLOSED

1. Your question is poorly formatted. Do you use quoye (>) when you mean code. See the help.
2. Installation from devtools is not supported or encouraged.
3. We make monthly (!!) releases to CRAN. Use those. The command is install.packages().
4. Your error message, buried in the ill-formatted question, suggested that the compiler in Ubuntu 12.04 may be too old. Nothing we can fix. Use an older RcppArmadillo if this is the binding issue--or better still upgrade your compile or Ubuntu version.
5. For what it is worth we run Travis CI on that Ubuntu version too. The last test four days ago preceding the last release used gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3.

I see, sorry for the trouble.

Nevertheless, CRAN-based installation throws exactly the same exception:

My gcc version is also 4.6.3

$ gcc --version

Updating OS at the host is not possible. Where can I get older sources?

Thanks!

from rcpparmadillo.

As I told you, g++-4.6.3 has been used for hundreds of builds by us. It is fine.

Now that you questions is legible, we see ccache clang++. Turn off that clang version and try again.

Older sources are in Archive/ section of CRAN. Each package has its full history.

Done! Thank you guys!

Ok. For that record, what does clang++ --version say? Something from the dark ages likes 3.2 or so? Newer versions should all work too.

There will be a cutoff point at which g++-4.6.* will be too old too once Conrad switches to a C++11 based version.

from rcpparmadillo.

Ha, 3.0!!!

$ clang++ --version

Jeebus. John von Neuman wrote that one himself while he was at Los Alamos, right?

True story!

Thank you again for the help and a good joke!
