编译GDB支持TUI模式 #

方法1：按照下面两个参考链接中尝试无效 #

https://mikeframpo.net/notes/2021/06/20/yocto-debugging-gdb.html

$ cat meta-kaba-hacks/recipes-devtools/gdb/gdb-%.bbappend 
EXTRA_OECONF += " --enable-tui"

方法2：更换顺序tui的配置顺序，重新编译 #

 vi ../sources/oe-core/meta/recipes-devtools/gdb/gdb-common.inc +40
 
 40 #PACKAGECONFIG[tui] = "--enable-tui,--disable-tui"
 41 PACKAGECONFIG[tui] = "--disable-tui,--enable-tui"

MACHINE=am335x-evm bitbake  -c clean gdb
MACHINE=am335x-evm bitbake  -c cleansstate gdb
MACHINE=am335x-evm bitbake  -k gdb
MACHINE=am335x-evm bitbake package-index

提示出错 #

Cannot enable the TUI: terminal doesn’t support cursor addressing [TERM=dumb]

解决办法

export TERM=linux
