Hello, I am trying to install R-3.4.1 on a linux?cluster. ?I always get the following error message: checking readline/history.h usability... yes checking readline/history.h presence... yes checking for readline/history.h... yes checking readline/readline.h usability... yes checking readline/readline.h presence... yes checking for readline/readline.h... yes checking for rl_callback_read_char in -lreadline... no checking for main in -lncurses... no checking for main in -ltermcap... no checking for main in -ltermlib... no checking for rl_callback_read_char in -lreadline... no configure: error: --with-readline=yes (default) and headers/libs are not available As you can see, the R configure script finds the header files, but something happens with the rl_callback_read_char. Here is more info on this from the config.log: configure:22995: checking for rl_callback_read_char in -lreadline configure:23020: mpicc -g -o conftest -O2 -fPIC -I/home/giessen/ivanov/build/packages/usr/include -I/home/giessen/ivanov/build/packages/usr/include/readline -I/home/giessen/ivanov/build/packages/usr/include -I/home/giessen/ivanov/build/packages/usr/include/readline -L/home/giessen/ivanov/build/packages/usr/lib64 -L/home/giessen/ivanov/build/packages/lib64 conftest.c -lreadline ? >&5 /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `PC' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tgetflag' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tgetent' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `UP' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tputs' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tgoto' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tgetnum' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `BC' /home/giessen/ivanov/build/packages/usr/lib64/libreadline.so: undefined reference to `tgetstr' collect2: error: ld returned 1 exit status I have the readline-6.3 library installed. I compiled it from source, so nothing should be missing. Any suggestions will be appreciated. Best regards, Martin
