Hello, I should use R on cygwin. I have ever install cygwin and now I try to install R. I have read the R manual and particularly the part : Installation R under Unix but I improved some difficulties for succeed in this task. Actually I have create a R repertory where I have unzipped the file R-2.9.1.tar.gz. In this repertory I do ./configure in cygwin but some errors appear and I don't understant them. I would specify that I'm a beginner on cygwin. ######################################################################### $ ./configure checking build system type... i686-pc-cygwin checking host system type... i686-pc-cygwin loading site script './config.site' loading build specific script './config.site' checking for pwd... /usr/bin/pwd checking whether builddir is srcdir... yes checking for working aclocal... missing checking for working autoconf... missing checking for working automake... missing checking for working autoheader... missing checking for gawk... gawk checking for grep that handles long lines and -e... /usr/bin/grep checking for egrep... /usr/bin/grep -E checking whether ln -s works... yes checking for bison... no checking for byacc... no checking for ar... ar checking for a BSD-compatible install... /usr/bin/install -c checking for sed... /usr/bin/sed checking for less... /usr/bin/less checking for perl... /usr/bin/perl checking whether perl version is at least 5.8.0... yes checking for dvips... /usr/bin/dvips checking for tex... /usr/bin/tex checking for latex... /usr/bin/latex checking for makeindex... /usr/bin/makeindex checking for pdftex... /usr/bin/pdftex checking for pdflatex... /usr/bin/pdflatex checking for makeinfo... /usr/bin/makeinfo checking whether makeinfo version is at least 4.7... yes checking for texi2dvi... /usr/bin/texi2dvi checking for unzip... /cygdrive/c/Program Files (x86)/Insightful/splus80/cmd/unz ip checking for zip... /cygdrive/c/Program Files (x86)/Insightful/splus80/cmd/zip checking for gzip... /usr/bin/gzip checking for firefox... no checking for mozilla... no checking for galeon... no checking for opera... no checking for xdg-open... no checking for kfmclient... no checking for gnome-moz-remote... no checking for open... no configure: WARNING: I could not determine a browser checking for acroread... no checking for acroread4... no checking for evince... no checking for xpdf... no checking for gv... no checking for gnome-gv... no checking for ggv... no checking for kghostview... no checking for open... no checking for gpdf... no configure: WARNING: I could not determine a PDF viewer checking for pkg-config... /usr/bin/pkg-config checking for gcc... gcc checking for C compiler default output file name... a.exe checking whether the C compiler works... yes checking whether we are cross compiling... no checking for suffix of executables... .exe checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -E checking whether gcc needs -traditional... no checking how to run the C preprocessor... gcc -E checking for g77... g77 ########################################################### Next I wrote : make on cygwin ##################################### $ make make: *** No targets specified and no makefile found.
