![Brian Norris](/assets/img/avatar_default.png)
gcc complains about the 'cols' variable being unused. This is unavoidable, given the ncurses getmaxyx() macro-based API, which wants to assign to a variable directly, even when we're not going to use it. Warning: gcc -O1 -Wall -Wshadow -W -Wformat -Wimplicit-function-declaration -Wimplicit-int -fstack-protector -D VERSION=\"1.0\" -c -o tui.o tui.c tui.c: In function ‘show_dialogue’: tui.c:288:12: warning: variable ‘cols’ set but not used [-Wunused-but-set-variable] int rows, cols; ^ So, add a hack to get rid of that warning.
