MySQL5.7.30 Linux编译过程记录

场景

CentOS Linux release 7.6.1810 (AltArch)

1)yum安装已有的GCC(gcc version 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC)),通过scl安装GCC（gcc version 7.3.1 20180303 (Red Hat 7.3.1-5) (GCC) ）

MySQL5.7.30版本源码依赖高版本的GCC，启用7.3版本GCC :scl enable devtoolset-7 bash

编译指令：

cmake ../ -DCMAKE_INSTALL_PREFIX=/opt/mysql  -DMYSQL_DATADIR=/opt/mysql/var  -DSYSCONFDIR=/etc -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DENABLED_LOCAL_INFILE=1 -DENABLE_DTRACE=0 -DDEFAULT_CHARSET=utf8mb4  -DDEFAULT_COLLATION=utf8mb4_general_ci -DWITH_EMBEDDED_SERVER=1 -DDOWNLOAD_BOOST=1 -DWITH_BOOST=/opt/mysql-src/boost_1_59_0

提示错误： error: could not split insn

问题原因：环境中有gcc -4.8.5的没有卸载

问题解决：yum -y remove gcc

如果把gcc version 7.3.1一同卸载，重新安装

2）/usr/bin/c++: No such file or directory

/bin/sh: /usr/bin/c++: No such file or directorymake[2]: *** [mysys_ssl/CMakeFiles/mysys_ssl.dir/build.make:63: mysys_ssl/CMakeFiles/mysys_ssl.dir/crypt_genhash_impl.cc.o] Error 127make[1]: *** [CMakeFiles/Makefile2:1320: mysys_ssl/CMakeFiles/mysys_ssl.dir/all] Error 2make: *** [Makefile:163: all] Error 2

解决：重新建立链接 ln -s /usr/bin/gcc /usr/bin/cc /usr/bin/c++

3）make编译出错

../archive_output_directory/libmysys_ssl.a(my_default.cc.o):(.data.DW.ref.__gxx_personality_v0[DW.ref.__gxx_personality_v0]+0x0): undefined reference to `__gxx_personality_v0'collect2: error: ld returned 1 exit statusmake[2]: *** [extra/CMakeFiles/comp_err.dir/build.make:94: extra/comp_err] Error 1make[1]: *** [CMakeFiles/Makefile2:6587: extra/CMakeFiles/comp_err.dir/all] Error 2make: *** [Makefile:163: all] Error 2

解决：删除cmake下的build的中间目录，编译的时候引用了GCC4.8.3的参与了编译，make clean不一定有效

4）修复源码中的头文件缺少问题

编辑sql/mysqld.cc 添加头文件#include <sys/prctl.h>

/opt/mysql-src/mysql-5.7.30/sql/mysqld.cc: In function 'passwd* check_user(const char*)':/opt/mysql-src/mysql-5.7.30/sql/mysqld.cc:1565:12: error: 'prctl' was not declared in this scope     (void) prctl(PR_SET_DUMPABLE, 1);            ^~~~~make[2]: *** [sql/CMakeFiles/sql.dir/build.make:2829: sql/CMakeFiles/sql.dir/mysqld.cc.o] Error 1make[1]: *** [CMakeFiles/Makefile2:8317: sql/CMakeFiles/sql.dir/all] Error 2make: *** [Makefile:163: all] Error 2

重新make编译
