Bonjour, J'ai besoin d'installer un package sous le logiciel R mais j'arrive pas à l'installer, apparemment il y a une librairie "fftw3" qui manque. Voici les résultats du terminal. ghassany@bronze:~$ R CMD INSTALL /users//ghassany/Desktop/VBmix_0.2.5.tar.gz * installing to library ‘/users/ghassany/R/i486-pc-linux-gnu-library/2.11’ * installing *source* package ‘VBmix’ ... checking for gcc... gcc -std=gnu99 checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc -std=gnu99 accepts -g... yes checking for gcc -std=gnu99 option to accept ISO C89... none needed checking for cos in -lm... yes checking for cblas_dgemm in -lgslcblas... yes checking for gsl_blas_dgemm in -lgsl... yes checking for fftw_execute in -lfftw3... no configure: error: "fftw3 library not found" ERROR: configuration failed for package ‘VBmix’ * removing ‘/users/ghassany/R/i486-pc-linux-gnu-library/2.11/VBmix’ Merci de m'aider.
