ncurses

I'm having some problems statically linking ncurses to one of my programs Here's a really simple sample program: #include<ncurses.h> int main(){ initscr(); printw("Hello world\n"); refresh(); getch(); endwin(); return 0; } When I compile it with gcc -static -lncurses hello_curses.c -o curses I get these errors: /tmp/ccwHJ6o1.o: In function `main': curses_hello.c:(.text+0x5): undefined reference to `initscr' curses_hello.c:(.text+0x14): undefined reference to `printw' curses_hello.c:(.text+0x1b): undefined reference to `stdscr' curses_hello.c:(.text+0x20): undefined reference to `wrefresh'

i'm currently working on a C++ project in which I need to display some extended characters (wchar_t). The main problem is that, even if it works fine in C (using wprintf ), it doesn't work in c++ using mvwaddwstr or waddwstr . Of course, i've set the locale like that: setlocale(LC_ALL, ""); , and nothing is displayed. Does someone got this problem before, or has an idea about that? Thanks. Here is the code: struct charMap { int x; int y; wchar_t value }; int i, x, y; wchar_t str[2]; struct charMap _charMap[2] = { {0,0,9474} {29, 29, 9474} }; initscr(); setlocale(LC_ALL, ""); for (y = 0 ; y <

I have a small ncurse program I'm running, but the output doesn't seem to show up unless I stick the wrefresh() in a while loop. Is there some buffering going on or something? I tried other refresh functions in the library and fflush with stddout (which I don't think makes sense, but worth a try), but nothing seems to work. A second small question: to make getch() non-blocking we need to call nodelay(win,TRUE) , right? void main() { initscr(); start_color(); init_pair(1,COLOR_YELLOW,COLOR_CYAN); WINDOW *win = newwin(10,10,1,1); wbkgd(win,COLOR_PAIR(1)); wprintw(win,"Hello, World."); wrefresh

I'm programming in C using ncurses libraries (it's the first time) and I've two problems. I'm on ubuntu with the default terminal (gnome terminal). 1) I need to resize the terminal. I used resizeter() and resize_term(), but they fail. 2) I use scrollok() function and the problem is that I lose scrolled lines (when I get back with wscrl(), there are blank lines). #include <ncurses.h> int main() { WINDOW *win, *win2; int i; char c; initscr(); cbreak(); noecho(); win=newwin(8,20,1,1); box(win,0,0); win2=newwin(6,18,2,2); scrollok(win2,1); wrefresh(win); wrefresh(win); for(i=0;i<15;i++){ c=wgetch

I am using Anaconda to manage my R-installation. It works great for packages available in the R-channels provided by Anaconda, but I am having troubles installing packages not contained in the Anaconda repos. I have tried a few different approaches, all listed below together with their error output. 1. install.packages('rafalib') Suggested to work here conda - How to install R packages that are not available in "R-essentials"? . My .libPaths() points to '/home/user/anaconda2/lib/R/library' . Out: --- Please select a CRAN mirror for use in this session --- Error in download.file(url, destfile =

I'm learning to program in C and want to be able to type characters into the terminal while my code is running without pressing return . My program works, however when I call initscr() , the screen is cleared - even after calling filter() . The documentation for filter suggests it should disable clearing - however this is not the case for me. #include <stdio.h> #include <curses.h> #include <term.h> int main(void) { int ch; filter(); initscr(); cbreak(); noecho(); keypad(stdscr, TRUE); while((ch = getch()) != EOF); endwin(); return 0; } Why does the above code still clearr the screen, and what

There are several libraries like ncurses that assist in making command-line GUIs. Simply put, how do they work? My first thought was that ncurses intercepts all keyboard input, and draws each "frame" by outputting it line-by-line normally. Closer inspection, however, reveals that each new frame overwrites the previous one. How does it modify lines that have already been outputted? Furthermore, how does it handle color? EDIT: The same question applies to anything with a "fancy" interface, like vim and emacs . Craig Text terminals have command sequences that do things like move the cursor to a

I'm writing an ncurses program and am trying to make it respond correctly to terminal resizing. While I can read the terminal dimensions correctly in my program, ncurses doesn't seem to deal with new dimensions correctly. Here's a (somewhat lengthy) sample program: #include <ncurses.h> #include <string.h> #include <signal.h> #include <sys/ioctl.h> void handle_winch(int sig){ struct winsize w; ioctl(0, TIOCGWINSZ, &w); COLS = w.ws_col; LINES = w.ws_row; wresize(stdscr, LINES, COLS); clear(); mvprintw(0, 0, "COLS = %d, LINES = %d", COLS, LINES); for (int i = 0; i < COLS; i++) mvaddch(1, i, '*');
