I want to install Rcpp using install.packages("Rcpp"), but it failed.
The error message:
* installing *source* package ‘Rcpp’ ...

Then I use

std::basic_streambuf<char, std::char_traits<char> >::seekoff(long long, std::_Ios_Seekdir, std::_Ios_Openmode)
I have searched for some solutions for that. It seems that it is because of the gcc version. But I don't know how to change the gcc version that R uses to compile Rcpp package.
回答1:
CRAN tests Rcpp just like any other of the (by now) 6700+ package.
You can see the aggregate test report and the test setups includes two Fedora-based machines:
- one fedora setup using clang and
- one fedora setup using g++.
As such your problems are possibly local, or simply due to using an older setup. In which case the Archive section gives you access to an older version.
回答2:
I've encountered a similar problem. And after some searches, here are the solutions to alter the compiler:
1. If you have the root privilege:
I found that the Makeconf file in R directory actually sets all the information that is needed for compilation.
To find the path to it, echo which R in the command line.
e.g. I got like:
/data/apps/R/3.1.2/bin/R
And then the file is in:
/data/apps/R/3.1.2/lib64/R/etc/Makeconf
then sudo edit the file on line CC = XXX and maybe more relative lines.
Problem solved!
2. If you only have local user privilege.
Add your own configurations to ~/.R/Makevars
However, @Dirk is probably right.
For me, I finally solved my problem by adding -Doff_t=__off_t to CFLAGS (My problem was error: unknown type name 'off_t'). And I got the halted error when I manually altered parts of the compilers...
