Hi, I'm trying to install readline to work with iyt via: yt/bin/pip install readline But gcc can't find the libncurses library: gcc -pthread -shared -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ -L/home/taskere/yt/lib/ -L/home/taskere/yt/lib64/ build/temp.linux-x86_64-2.7/Modules/2.x/readline.o readline/libreadline.a readline/libhistory.a -lncurses -o build/lib.linux-x86_64-2.7/readline.so /usr/bin/ld: cannot find -lncurses which is totally on this machine: [taskere@iqaluk ~]$ locate libncurses /lib64/libncurses.so.5 /lib64/libncurses.so.5.7 /lib64/libncursesw.so.5 /lib64/libncursesw.so.5.7 /lib64 is in my LD_LIBRARY_PATH, but it looks like gcc doesn't check that. Any ideas? Elizabeth
