I'm new to Linux and R.

I installed R 2.12 in Ubuntu 11.04. Today I tried to install a new package, so I ran the following command:

install.packages('XML')

But the installation failed and gave the following information:

* installing *source* package ‘XML’ ...
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... yes
checking whether we are cross compiling... no

ERROR: configuration failed for package ‘XML’
* removing ‘/home/spirit/R/i686-pc-linux-gnu-library/2.12/XML’

The downloaded packages are in
    ‘/tmp/RtmpoZYxnv/downloaded_packages’
Warning message:
In install.packages("XML") :
  installation of package 'XML' had non-zero exit status

I also tried:

sudo install.packages('XML')

But it gives the same error information.

Anyone can give me any advice?

The install.packages method

You need to install the ubuntu package libxml2-dev So in a shell prompt type:

sudo apt-get update
sudo apt-get install libxml2-dev

You will need special sudo powers for this.

Ubuntu package method

As Richie and Dirk mentioned, you can also use:

sudo apt-get install r-cran-xml

If you go down this path, I would recommend that you check out the R ubuntu sources page which will ensure you have a current version of R and the associated R packages. This could be important if you are using the LTS version of ubuntu.
