e.g. GNU tar version 1.15 or later, or that from the `libarchive' (as used on OS 10.[67]) or `Heirloom Toolchest' distributions.


for some Subversion clients `http:' may appear to work, but requires continual redirection.


which use `lib' rather than `lib64' for their primary 64-bit library directories.


for example, if you configured R with `--without-recommended'.


Debian/Ubuntu use a rather old version of TeXLive and so need Debian package `texlive-fonts-extra' installed.


with possible values `i386', `x64', `32' and `64'.


mainly on RedHat and Fedora, whose layout is described here.


For those using GNU binutils, where gold is used as the linker: this might be enabled when gcc was built or selected via the alternatives mechanism.


formerly known as EM64T.


unless they were excluded in the build.


its binding is locked once that files has been read, so users cannot easily change it.


If a proxy needs to be set, see ?download.file.


for a small number of CRAN packages where this is known to be safe and is needed by the autobuilder this is the default. Look at the source of `tools:::.install_packages' for the list.


`X/Open Portability Guide', which has had several versions.


On some systems setting LC_ALL or LC_MESSAGES to `C' disables LANGUAGE.


If you try changing from French to Russian except in a UTF-8 locale, you will most likely find messages change to English.


the language written in England: some people living in the USA appropriate this name for their language.


with Americanisms.


also known as IEEE@tie{}754


at least when storing quantities: the on-FPU precision is allowed to vary


this comment has been in the manual since 2005.


e.g. Bessel, beta and gamma functions


including copying `MkRules.dist' to `MkRule.local' and selecting the architecture.


also known as IEEE@tie{}754


Note that C11 compilers (when they appear) need not be C99-compliant: R requires support for double complex which is optional in C11 but is mandatory in C99.


`-std=c99' excludes POSIX functionality, but `config.h' will turn on all GNU extensions to include the POSIX functionality.


apparently when built by default, but not for example as built for Fedora 15.


specifically, the C99 functionality of headers `wchar.h' and `wctype.h', types wctans_t and mbstate_t and functions mbrtowc, mbstowcs, wcrtomb, wcscoll, wcstombs, wctrans, wctype, and iswctype.


Such as GNU tar 1.15 or later, bsdtar (from http://code.google.com/p/libarchive/, as used by FreeBSD and OS 10.[67]) or tar from the Heirloom Toolchest (http://heirloom.sourceforge.net/tools.html).


texi2dvi is normally a shell script. Some versions, e.g. that from texinfo 4.13a, need to be run under bash rather than a Bourne shell as on, say, Solaris.


also known as ttf-mscorefonts-installer in the Debian/Ubuntu world: see also http://en.wikipedia.org/wiki/Core_fonts_for_the_Web.


ttf-liberation in Debian/Ubuntu.


Using the Oracle Solaris Studio cc and f95 compilers


We have measured 15-20% on `i686' Linux and around 10% on `x86_64' Linux.


On HP-UX fort77 is the POSIX compliant FORTRAN compiler, and comes after g77.


as well as its equivalence to the Rcomplex structure defined in `R_ext/Complex.h'.


In particular, avoid g77's `-pedantic', which gives confusing error messages.


e.g., to use an optimized BLAS on Sun/Sparc


for example, X11 font at size 14 could not be loaded.


or -mtune=corei7 for Intel Core i3/15/17 with gcc >= 4.6.0.


TeXLive is recommended.


including gcc for Sparc from Oracle.


Windows DLLs need to have all links resolved at build time and so cannot resolve against `R.bin'.


For example, the Cygwin version of make 3.81 fails to work correctly.


for R 2.14.2 and later.


such as sort, find and perhaps make.


these flags apply to the compilers: some of the tools use different flags. 32-bit builds are the default.
