## By means of this file you can (also) provide default values for the
## configuration process. To set variables, uncomment the VAR=DEFAULT
## lines and set DEFAULT according to your needs.
## See etc/Renviron.in for further variables you may wish to set.
## The command used to spool PostScript files to the printer.
## If unspecified, the system will look for either 'lpr' or 'lp'.
## R_PRINTCMD=lpr
## The paper size for the local (PostScript) printer.
## It must either be left blank or set to one of 'a4' or 'letter'.
## If left blank the system will use 'a4'.
## R_PAPERSIZE=a4
## Set the default behavior of R when ending a session
## Set this to one of '--save' or '--no-save' depending whether you
## want automatic saving of '.RData' or not.
## Note that this applies to interactive and batch use,
## but NOT to the utility R CMD BATCH
## (which defaults to --save irrespective of this setting)
## R_BATCHSAVE=
## The command which runs the C compiler.
## If unspecified, a search is made for gcc and cc (in that order).
## To override this choice, specify the name of the command which runs
## the compiler here, for example 'c99'.
## It is also convenient to set the architecture here, e.g. 'gcc -m32'.
## CC=
## Debugging and optimization options for the C compiler.
## Use this to specify CFLAGS for the version of the C compiler
## specified above.
## If unspecified, defaults to '-g -O2' for gcc,
## and '-g' in all other cases except icc (for which see R-admin.html).
## CFLAGS=
## Defines for C compilation.
## Use this to specify defines to be used in the compilation of R,
## e.g. -DUSE_TYPE_CHECKING_STRICT
## DEFS=
## The following additional CFLAGS to be used only in the main
## compilation and only in building shared objects respectively.
## For example, on some systems one needs 'MAIN_CFLAGS=-pg' when
## profiling.
## MAIN_CFLAGS=
## SHLIB_CFLAGS=
## Header file search directory ('-IDIR') and any other miscellaneous
## options (such as defines) for the C preprocessor and compiler.
## If unset defaults to '-I/usr/local/include', with '-I/sw/include'
## prepended on systems using Fink with root '/sw'.
## CPPFLAGS=
## The command which runs the FORTRAN 77 compiler.
## If this is not specified, a search is made for
## f95 fort xlf95 ifort ifc efc pgf95 lf95 gfortran ftn g95
## f90 xlf90 pgf90 pghpf epcf90
## g77 f77 xlf frt pgf77 cf77 fort77 fl32 af77
## On HPUX fort77 is the POSIX compliant FORTRAN compiler, and replaces
## f77 in the search list.
## If CC is gcc, first preference is given to the matching FORTRAN
## compiler (g77 or gfortran).
## If none of these is found, R cannot be compiled.
## F77=
## Options for the FORTRAN 77 compiler.
## Use this to specify FFLAGS for the version of the compiler specified
## above. If unspecified, defaults to '-g -O2' for g77/gfortran,
## otherwise '-g' if this is accepted, otherwise ''.
## FFLAGS=
## Options for safe compilation under the FORTRAN 77 compiler.
## Use this to specify FFLAGS for the version of the compiler specified
## above, using as accurate a result as possible, e.g. no optimization
## or using -ffloat-store.
## SAFE_FFLAGS=
## The following additional FFLAGS to be used only in the main
## compilation and only in building shared objects respectively.
## For example, on some systems one needs 'MAIN_FFLAGS=-pg' when
## profiling.
## MAIN_FFLAGS=
## SHLIB_FFLAGS=
## The command to be used to load the main R binary.
## This is usually the FORTRAN 77 or C compiler, but the automatic
## choice can be overriden by means of this variable.
## MAIN_LD=
## The flags which are necessary for loading main program which will
## load DLLs at runtime. HP-UX and Linux-elf are examples of platforms
## which use this. These platforms are already taken care of by
## configure, and anything set here will be in addition unless MAIN_LD
## is given.
## For example, one can set flags for profiling here.
## MAIN_LDFLAGS=
## Any special flags which must be used when compiling C code to be
## turned into a shared object. This is typically something like
## '-fpic' or '-fPIC'. If this variable is left unspecified an attempt
## is made to automatically detect the correct value.
## CPICFLAGS=
## The following variable can be used to provide any PIC flags for the
## FORTRAN 77 compiler. If this variable is left unspecified an
## attempt is made to automatically detect the correct value.
## FPICFLAGS=
## The command to be used to create shared objects which contain object
## files from a C or FORTRAN 77 compiler only. This is usually the C
## compiler or 'ld', but the automatic choice can be overridden by means
## of this variable.
## SHLIB_LD=
## Any special flags which are required by the linker when creating
## shared objects containing object files from a C or FORTRAN 77
## compiler only. This is usually automatically detected by configure,
## and anything set here will be in addition unless SHLIB_LD is given.
## SHLIB_LDFLAGS=
## ditto for a dynamic library: DYLIB_LDFLAGS defaults to SHLIB_LDFLAGS
## DYLIB_LD=
## DYLIB_LDFLAGS=
## The appropriate 'lib' dir, normally 'lib', but 'lib64' on Linux on
## x86_64, mips64, ppc64, sparc64, s390x but not ia64.
## LIBnn=
## Stripping ('-s'), path ('-L'), and any other miscellaneous options
## for the linker.
## '-L' options set here will be prepended to LD_LIBRARY_PATH (or its
## system equivalent) at run time.
## If unset defaults to '-L/usr/local/lib', with '-L/sw/lib' prepended
## on systems using Fink with root '/sw'.
## On some Linux 64-bit systems its default is -L/usr/local/lib64.
## If LIBnn is set it defaults to -L/usr/local/$LIBnn.
## LDFLAGS=
## The command which runs the C++ compiler. It not specified, configure
## uses the values of the environment variables 'CXX' or 'CCC' if set,
## and then looks under the names 'c++', 'g++', 'gcc', 'CC', 'cxx', and
## 'cc++' (in that order).
## CXX=
## Options for the C++ compiler.
## CXXFLAGS=
## Any special flags which must be used when compiling C++ code to be
## turned into a shared object. If this variable is left unspecified
## an attempt is made to automatically detect the correct value.
## CXXPICFLAGS=
## The command to be used to load shared objects which contain object
## files from the C++ compiler. This is usually the C++ compiler/linker,
## but the automatic choice can be overridden by means of this
## variable.
## SHLIB_CXXLD=
## Any special flags which are required when creating shared objects
## containing object files from a C++ compiler. This is usually
## automatically detected by configure, and anything set here will be in
## addition unless SHLIB_CXXLD is given.
## SHLIB_CXXLDFLAGS=
## FORTRAN 95 compiler: optional for use in packages.
## Analogous to the F77 and CXX settings.
## FC=
## FCFLAGS=
## FCPICFLAGS=
## SHLIB_FCLD=${FC}
## Unlike SHLIB_CXXLDFLAGS, SHLIB_FCLDFLAGS is never additional
## SHLIB_FCLDFLAGS=${SHLIB_LDFLAGS}
## Tcl/Tk settings.
## Use TCLTK_LIBS for all '-L' and '-l' options needed for linking
## against the Tcl and Tk library.
## TCLTK_LIBS=
## Use TCLTK_CPPFLAGS for all '-I' options needed for finding the tcl.h
## and tk.h headers.
## TCLTK_CPPFLAGS=
## Browser default
## Default setting for the R_BROWSER env variable
## If unset configure searches in turn for (currently)
## firefox mozilla galeon opera xdg-open kfmclient gnome-moz-remote open
## and uses the full path.
## R_BROWSER=
## BLAS and LAPACK settings
## Use BLAS_LIBS for all '-L' and '-l' options needed for linking
## against an external BLAS implementation.
## BLAS_LIBS=
## Use LAPACK_LIBS for all '-L' and '-l' options needed for linking
## against an external LAPACK implementation.
## Note that (see R-admin) that our main intention is to allow a
## LAPACK-containing BLAS to be used, so this is rarely needed, and
## it is not used if the BLAS already contains LAPACK.
## LAPACK_LIBS=
## Make name.
## Set this if you want to use a make by another name.
## For example, if your GNU make is called 'gmake', use 'MAKE=gmake'.
## MAKE=
## Tar name
## Set this to prefer a tar which has the capability to automagically
## read compressed archives. The default is to choose 'gtar' or
## 'gnutar'(normally GNU tar) then 'tar'.
## Note that 'bsdtar' (from the libarchive project) is known to create
## archives in a non-POSIX format that untar() cannot read,
## so should be avoided.
## TAR=
