R and Tcl/Tk system libraries

[jwhite]

Hi,

For the past several days I've been fighting with R to install a software package "compcodeR". This package requires Tcl/Tk libraries be installed on the system. So I installed these libraries on our cluster (since they were not present). The install location is /usr/local/lib for Tcl/Tk 8.6.

Unfortunately, R will not install the compcodeR package because it cannot detect the Tcl or Tk libraries. (Yes, the libraries exists and are functional.) Adding /usr/local/lib to the $PATH and $LD_LIBRARY_PATH env. variables made no difference. Copying the .so library files to R's lib directory --as other libraries are--made no difference. R still complains that it cannot detect the tcl/tk libraries.

Has anyone else had a similar problem? Does anyone know why R cannot detect these libraries even after setting up the environment? Am I using the wrong env variable?

Any help is appreciated.
Thanks,

I think R needs to be compiled with tcl/tk already installed. Some packages need the dev version of tcl/tk and won't work with the normal version.

What does R say when you give it: capabilities("tcltk")

FALSE

possibly because the shared object libraries aren't available or in the right place.

This is the error returned during package installation:

The same error occurs if the package is installed from the command-line.

Hello!

I know this thread is a little bit old but I've got the same error with compcodeR now. The installation seems to work well, but when I try to load the library the following error appears:

sh: otool: command not found
Error : .onLoad failed in loadNamespace() for 'tcltk', details:
call: system2("otool", c("-L", shQuote(DLL)), stdout = TRUE)
error: error in running command

Do you know any trick to fix this? I've never had troubles with compcodeR before, so I'm a bit confused. It worked well until now

otool is pretty much Apple Mac specific.
You need to install the developer tools to get access to otool. I'm not sure if you need Xcode, too.
