R devel - Dec 2005 - R-beta: configure problem (tcltk) on 64 bit Red Hat EL

Dear developeRs,

I use Red Hat Enterprise Linux WS release 4 (Nahant Update 2) on an
x86_64 machine (two Intel P4 CPUs with 64 bit support), and
R-beta_2005-12-12_r36712.tar.gz.

If I run configure without any options, it does not list tcltk among
the supported interfaces:

./configure
[...]
R is now configured for x86_64-unknown-linux-gnu

  Source directory:          .
  Installation directory:    /usr/local

  C compiler:                gcc  -g -O2
  C++ compiler:              g++  -g -O2
  Fortran compiler:          g77  -g -O2

  Interfaces supported:      X11
  External libraries:        readline, BLAS(generic)
  Additional capabilities:   PNG, JPEG, iconv, MBCS, NLS
  Options enabled:           R profiling

  Recommended packages:      yes

It seems to find tcl and tk, but not be able to compile/link them:
[...]
checking /usr/include/tcl.h usability... yes
checking /usr/include/tcl.h presence... yes
checking for /usr/include/tcl.h... yes
[...]
checking /usr/include/tk.h usability... yes
checking /usr/include/tk.h presence... yes
checking for /usr/include/tk.h... yes
checking whether compiling/linking Tcl/Tk code works... no


Looking in config.log, it seems that even though libX11 has been found
in /usr/X11R6/lib64, it is not searched for in that directory when
testing compiling/linking Tcl/Tk:

configure:35654: checking for X

configure:38486: $? = 1

Running ./configure LDFLAGS="-L/usr/local/lib64  -L/usr/X11R6/lib64"
solves/avoids the problem for me.

I thought I'd report the problem anyway, since I don't know if it is the
intended behaviour of configure.

Yes, the R-admin manual warns of this.

It is a problem with your particular OS, as e.g. FC3 does

checking for tclConfig.sh... no
checking for tclConfig.sh in library (sub)directories... 
/usr/lib64/tclConfig.sh
checking for tkConfig.sh... no
checking for tkConfig.sh in library (sub)directories... 
/usr/lib64/tkConfig.sh

and that config file has

# Additional libraries to use when linking Tk.
TK_LIBS='-L/usr/X11R6/lib64 -lX11 -ldl  -lieee -lm'

Unfortunately you have removed the crucial parts of where your configure 
got the configuration info from.

You are right.  I have both the i386 and x86_64 RPMs installed.

Thank you!  This works like a charm.

You are right.  As Martyn suggested, configure picked up
/usr/lib/{tcl,tk}Config.sh instead of /usr/lib64/{tcl,tk}Config.sh
because I have both i386 and x86_64 versions of the RPMs installed.

Typically me! :-)


Thanks, both of you!

At a closer look, R was searching /usr/lib before /usr/lib64 which seems 
sub-optimal, so I have reversed this (and added /usr/local/lib64 to the 
list before /usr/local/lib).  Nevertheless, for some builds (e.g.
32-bit R on 64-bit Linux) you will need to specify the paths as the manual 
says.
