From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322) Description of problem: When configuring software that uses "make menuconfig" and wants to draw the extended ASCII "line" characters (busybox, uClibc or buildroot, for example), the display does not look right (it is "blocky" and "flat" (2 dimmensional), and sometimes does weird things that makes it hard to use (like having text from a previous screen appear when navigating into a menu tree)). The issue is that menuconfig should be drawing the special "line" characters, but it is not. I have noticed this on fc3 and fc4. When I do the same thing on RH 7.3 or a "Linux From Scratch" build, the display is correct: It has shadowed areas of the screen, and nice clean lines as borders. I assume that this has something to do with ncurses, or perhaps supported character sets. Version-Release number of selected component (if applicable): ncurses-5.4 How reproducible: Always Steps to Reproduce: 1. download buildroot-x.x.x (http://buildroot.uclibc.org/downloads/snapshots/) 2. tar jxvf buildroot* && cd buildroot 3. make menuconfig Actual Results: Ugly malfuctioning configuration menues. Expected Results: Nice clean configuration menues. Additional info: Observed on FC3 and FC4. RH9 returns an error: usr/bin/ld: cannot find -lncurses (Even though ncurses 5.3 is installed.) Works as expected on RH 7.3
It can be depend on many things: a) terminal emulator type b) selected font c) LANG environment variable d) TERM environment variable e) TERMINFO environment variable f) how your application is writen (ncurses or slang). We have tried your issue using 'xterm' (Launch 'xterm' and set some shell-environment-variables at the command prompt of this new 'xterm'): 1) Launch (at command prompt) : xterm -fn 8x16 2) Set shell-environment-variable LANG : export LANG=en_US 3) Set shell-environment-variable TERM : export TERM=xterm 4) Set shell-environment-variable TERMINFO: export TERMINFO=/usr/share/terminfo 5) Launch (in the corresponding directory): make menuconfig Expected Results: Nice clean configuration menues. Your application probably uses ncurses-library. This library does not support UTF-8 fonts. A UTF-8 font needs slang-library. NOTE: Not every terminal is able to support UTF-8 encoding. Not every 'selected font' contains 'extended ACSII' characters (ACS_HLINE, ACS_VLINE, ...). Use shell-environment-variable LD_LIBRARY_PATH to help the dynamic-loader to find curses/ncurses library. Example: export LD_LIBRARY_PATH=/lib:/usr/lib Petr Raszyk
