I've looked through the archives and have seen that others had a similar problem: http://tolstoy.newcastle.edu.au/R/e2/help/06/09/0571.html I'm trying to install rimage and I get the following warning: ===========================================downloaded 323Kb * Installing *source* package 'rimage' ... checking for g++... g++ checking for C++ compiler default output... a.out checking whether the C++ compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... checking for suffix of object files... o checking whether we are using the GNU C++ compiler... yes checking whether g++ accepts -g... yes checking for gcc... gcc checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ANSI C... none needed checking how to run the C preprocessor... gcc -E checking for egrep... grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking fftw.h usability... no checking fftw.h presence... no checking for fftw.h... no configure: error: Sorry, can't find fftw header ERROR: configuration failed for package 'rimage' ** Removing '/usr/lib/R/library/rimage' The downloaded packages are in /tmp/Rtmp2IVErp/downloaded_packages Warning message: installation of package 'rimage' had non-zero exit status in: install.packages() ===================================================== I have installed fftw2 and libjpeg and they reside in /usr/include where I believe R should find them, but the above indicates that it does not. I also copied them to usr/local/ in case R looked for these files there. System: opensuse10.2 R2.4.1 Thanks for any help, james [[alternative HTML version deleted]]
