交叉编译android版本的gdb

来源：互联网发布：mac怎么下载单机游戏编辑：程序博客网时间：2024/06/08 18:26

(1)配置交叉编译链接

make-standalone-toolchain.sh

然后

make-standalone-toolchain.sh

然后配置PATH,CC,C++

export CC="aarch64-linux-android-gcc -pie -fPIE --sysroot=..."

export CXX="aarch64-linux-android-g++ -pie -fPIE --sysroot=..."

export CXXFLAGS="-lstdc++"

(2)下载源码

./configure --host=aarch64-linux-android --target=aarch64-linux-android --prefix=.......out

make

make install

-----------------

问题

(1) 找不到stdio_ext.h这个文件

需要将android 6.0中的./bionic/libc/include/stdio_ext.h 拷贝到sysroot环境中。

https://android.googlesource.com/platform/bionic/+/android-6.0.1_r73/libc/include/stdio_ext.h

可以从这里下到

(2)../common/sim-events.h:94:3: error: unknown type name 'SIM_ELAPSED_TIME'
SIM_ELAPSED_TIME resume_wallclock;

需要在sim-events.h中添加 #include "sim-utils.h"

(3) ./memory.h:29:44: error: unknown type name 'sim_cpu'

在sim/aarch64/cpustate.h中增加#include "sim-base.h"

(4)linux-thread-db.c: In function 'thread_from_lwp':
linux-thread-db.c:344:5: error: 'td_thrhandle_t' has no member named 'th_unique'
th.th_unique = 0;

//th.th_unique = 0;将该文件中的这行注释掉

(5)undefined reference to `setpwent'

修改complete.c对应行

改为：

#if defined(HAVE_GETPWENT)

setpwent();

#endif

(6)linux-low.c:130:3: error: conflicting types for 'Elf64_auxv_t'
} Elf64_auxv_t;

修改sysroot/usr/include/elf.h文件，将冲突名，改为其他名称

(7)tracepoint-ipa.o: In function `get_timestamp':
/home/secniu/works/android_tools/android_gdb/gdb-7.11/gdb/gdbserver/tracepoint.c:7349: undefined reference to `rpl_gettimeofday'

(8) line 81: makeinfo: command not found

安装makeinfo命令，ubuntu环境需要安装texinfo命令
