3559 编译gdb-7.9

Posted 2022-12-10 eastgeneral

1、安装ncurses-6.0 这个在3559 sdk中有，可以直接使用

./configure --with-shared --without-debug --without-ada --enable-overwrite

 

2、编译gdb

./configure --target=aarch64-himix100-linux --prefix=/opt/hisi-linux/x86-arm/hi3559av100_aarch64_himix100_gdb/ --disable-werror --with-python

3、编译gdbserver

./configure --target=aarch64-himix100-linux --prefix=/opt/hisi-linux/x86-arm/hi3559av100_aarch64_himix100_gdb/ --disable-werror CC=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-gcc AR=/opt/hisi-linux/x86-arm/aarch64-himix100-linux/bin/aarch64-himix100-linux-ar --host=aarch64-himix100-linux CFLGAS=‘-mcpu=cortex-a73.cortex-a53 $CFLAGS‘

 

编译gdbserver过程中会遇到这样的错误，

proc-service.c:148:1: error: conflicting types for ‘ps_lsetfpregs‘
ps_lsetfpregs (gdb_ps_prochandle_t ph, lwpid_t lwpid, void *fpregset)

 

proc-service.c:148:1: error: conflicting types for ‘ps_lsetfpregs‘
ps_lsetfpregs (gdb_ps_prochandle_t ph, lwpid_t lwpid, void *fpregset)

 

linux-aarch64-low.c:1090:1: error: conflicting types for ‘ps_get_thread_area‘
ps_get_thread_area (const struct ps_prochandle *ph,

需要将上面出错的文件中的重复函数定义注释掉

解决方法参考了下面的文章 转载

问题1：
error: this statement may fall through [-Werror=implicit-fallthrough=]
error: right-hand operand of comma expression has no effect [-Werror=unused-value]
error: ‘hexchars’ defined but not used [-Werror=unused-const-variable=
解决：make CFLAGS=’-Wno-implicit-fallthrough -Wno-unused-value -Wno-unused-const-variable’

问题2：
configure: error: no termcap library found
解决：
下载termcap源码安装，下载地址：https://ftp.gnu.org/gnu/termcap/

问题3：
amd64-linux-nat.c:485:1: error: conflicting types for ‘ps_get_thread_area’
linux-x86-low.c:167:1: error: conflicting types for ‘ps_get_thread_area’
还有几处冲突得，使用相同得处理方法
解决：修改文件gdb-7.6.1/gdb/amd64-linux-nat.c gdb-7.6.1/gdb/gdbserver/linux-x86-low.c
，屏蔽ps_get_thread_area定义（不确定是否有影响）
