ARM机下编辑安装mysql错误处理

 ARM机下编辑安装mysql5.7.38

操作系统：CentOS Linux release 7.5.1804 (AltArch)

make时报错 

错误一：storage/innobase/handler/handler0alter.cc:9025:1: error: could not split insn

解决方案：

编辑CMakeLists.txt文件，添加红色字体部分

vim /opt/mysql-5.7.38/storage/innobase/CMakeLists.txt

# A GCC bug causes crash when compiling these files on ARM64 with -O1+
# Compile them with -O0 as a workaround.
IF(CMAKE_COMPILER_IS_GNUCXX AND CMAKE_SYSTEM_PROCESSOR MATCHES "aarch64")
  # Bug was fixed in GCC 5.2, so workaround only needed < 5.2
  EXECUTE_PROCESS(COMMAND ${CMAKE_C_COMPILER} -dumpversion
                  OUTPUT_VARIABLE GCC_VERSION)
  IF(GCC_VERSION VERSION_LESS 5.2)
    INCLUDE(${MYSQL_CMAKE_SCRIPT_DIR}/compile_flags.cmake)
    ADD_COMPILE_FLAGS(
      btr/btr0btr.cc
      btr/btr0cur.cc
      buf/buf0buf.cc
      gis/gis0sea.cc
      fts/fts0fts.cc
      handler/handler0alter.cc
      row/row0mysql.cc
      srv/srv0srv.cc
      COMPILE_FLAGS "-O0"
      )
  ENDIF()
ENDIF()
 

之后重新编辑即可。

错误二：

sql/mysqld.cc:1565:36: error: ‘prctl’ was not declared in this scope

 解决方案：

cp /usr/include/sys/prctl.h /opt/mysql-5.7.38/include/

 编辑mysqld.cc文件，添加红色字体部分

vim /opt/mysql-5.7.38/sql/mysqld.cc
