Merry Chrismas to everyone, I have came across a problem when I tried to install 'qvalue' package, which depends on 'tcltk', in Centos 5.x, 64 bit. I compiled R 2.12.1(./configure --enable-R-static-lib --with-x --enable-memory-profiling) and tcl/tk(8.5.9). There is no warning message when I finished configure and make step. But when I finshed install and tested 'tcltk', I recieve the following messgae: Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error in library(tcltk) : .First.lib failed for 'tcltk' BTW, standalone tcltk code can be excuted in my platform. Does anyone have some suggestions? -- Best Regards, Yang Yifan | Statistic and Probability| School of Management | University of Science and Technology of China | Mobile: +86 1386672 1658 | E-mail: enthumelon@gmail.com | Privileged/Confidential information may be contained in this message.
