For example: $ echo -e "Line: \033(0qqqqqqqq\033(B Normal: qqqqqqqq" Results in output: Line: qqqqqqqq Normal: qqqqqqqqq When it should result in a horizontal line after "Line:". (Screen terminal type is "screen" and underlying terminal type can be for example "vt102" or "xterm"). The problem is due to screen being compiled without TERMINFO defined, meaning that it uses termcap control codes, while ncurses is built with terminfo support only (without termcap backwards compatibility support). The root of the problem is the termcap/terminfo detection at line 666 in configure.in. The detection uses AC_TRY_RUN which always fails when cross-compilation is used, and TERMINFO is therefore never defined. An easy fix could be to force terminfo support in the Buildroot screen makefile: --- screen.mk 2012-02-29 23:19:47.000000000 +0100 +++ screen-fixed.mk 2012-05-07 10:42:50.938185870 +0200 @@ -10 +10 @@ -SCREEN_CONF_ENV = CFLAGS=-DSYSV=1 +SCREEN_CONF_ENV = CFLAGS="-DSYSV=1 -DTERMINFO" -- Configure bugmail: https://bugs.busybox.net/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
