[BioC] tcltk problem under Linux (both 32 and 64 bits)

[Groot, Philip de]

Hello Robert,
 
tcltk is FALSE (but I allready knew this):
 
 > capabilities()
    jpeg      png    tcltk      X11 http/ftp  sockets   libxml     fifo 
    TRUE     TRUE    FALSE     TRUE     TRUE     TRUE     TRUE     TRUE 
  cledit    iconv      NLS 
    TRUE     TRUE     TRUE 

The corresponding output of the configure script is as follows (after unpacking R again and running the configure script for the first time again):
 
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... no
checking /usr/include/tcl8.4/generic/tcl.h usability... no
checking /usr/include/tcl8.4/generic/tcl.h presence... no
checking for /usr/include/tcl8.4/generic/tcl.h... no
checking /usr/include/tcl8.4/tcl.h usability... no
checking /usr/include/tcl8.4/tcl.h presence... no
checking for /usr/include/tcl8.4/tcl.h... no
checking /usr/include/tcl.h usability... yes
checking /usr/include/tcl.h presence... yes
checking for /usr/include/tcl.h... yes
checking for tk.h... no

Thanks for your help (the tip to look at the configure-output). Apparently, the tcltk-devel rpm-package is installed instead of the tk-devel rpm-package (confusing names anyway). The problem is corrected, the compilation is fine, and the tcltk library works properly now.
 
Thanks!
 
Philip

Start up your R and look at the output of
capabilities()

On my system I get:
     jpeg      png    tcltk      X11 http/ftp  sockets   libxml     fifo
     TRUE     TRUE     TRUE     TRUE     TRUE     TRUE     TRUE     TRUE
   cledit    iconv      NLS
     TRUE     TRUE     TRUE

anything that is FALSE indicates functionality you will not be able to
access.

Does it say tcltk is TRUE or FALSE

the problem below is clearly a problem with the tcltk library which is
part of R and NOT part of Bioconductor. So, I am doubting that it is
properly installed.  Probably you have tcl/tk in some odd spot. You can
find out what is happening by closely examining the output of configure
(which would have run when you first installed R, if done from source)

best wishes
   Robert

However, both the normal and development packages for both tcl and tk are properly installed. tclsh and wish can be executed properly. No problem at all!
