一、GDB在海思平台上的编译

编译环境

一、[下载GDB压缩包 gdb-8.3.tar.gz][GDB_ gdb-8.3.tar.gz]

二、解压压缩包

tar xvf gdb-8.3.tar.gz

三、配置编译器

进入到GDB的文件目录，然后执行

./configure --host=arm-himix100-linux --program-prefix=arm-hisi- --prefix=`pwd`/output

四、修改文件

由于海思提供的交叉编译工具的版本比较旧，在编译的时候回出现一些错误

1、dwarf-index-write.c的错误

CXX    dwarf-index-write.o
    dwarf-index-write.c: In member function 'void debug_names::build()':
    dwarf-index-write.c:704:32: error: 'log2' is not a member of 'std'
           (std::pow (2, std::ceil (std::log2 (name_count * 4 / 3))));
                                    ^~~
    dwarf-index-write.c:704:32: note: suggested alternative:
    In file included from /opt/toolchain/arm-himix100-linux/target/usr/include/features.h:416:0,
                     from /opt/toolchain/arm-himix100-linux/target/usr/include/stdio.h:28,
                     from build-gnulib/import/stdio.h:43,
                     from common/common-defs.h:76,
                     from defs.h:28,
                     from dwarf-index-write.c:20:
    /opt/toolchain/arm-himix100-linux/target/usr/include/bits/mathcalls.h:158:1: note:   'log2'
     __MATHCALL (log2,, (_Mdouble_ __x))
     ^
    make[2]: *** [dwarf-index-write.o] Error 1
    make[2]: Leaving directory `/opt/hisi-linux/GDB/gdb-8.3/gdb'
    make[1]: *** [all-gdb] Error 2
    make[1]: Leaving directory `/opt/hisi-linux/GDB/gdb-8.3'
    make: *** [all] Error 2

解决方法：使用log函数替换log2方法

将dwarf-index-write.c
        m_bucket_table.resize
          (std::pow (2, std::ceil (std::log2 (name_count * 4 / 3))));
    使用log函数替换log2方法
        m_bucket_table.resize
          (std::pow (2, std::ceil (std::log(name_count * 4 / 3) / std::log((float)2.0))));

2、undefined reference to \`\_obstack\_free' 错误

解决方法：使用宏定义使用\_obstack\_free函数替换obstack\_free

在obstack.h中增加定义
    #ifndef obstack_free
    #define _obstack_free obstack_free
    #endif

五、编译、安装

make && make install

六、生成编译文件

在GDB的目录下会有一个Output目录，下面就是我们编译出来的文件。
