arm环境编译兼容性问题踩坑
pika在arm环境编译
- what: pika在arm环境编译
- where: centos8 aarch64
- when: 2022.1.4
- who: 无名
- why: 记录
- how:
- release： 3.6.6
1.安装依赖
yum -y install epel-release
yum install gcc-c++ gcc make cmake vim wget git which -y
dnf --enablerepo=powertools install glog-devel -y
dnf --enablerepo=powertools install snappy-devel -y
yum -y install gflags-devel
yum install -y diffutils
dnf --enablerepo=powertools install protobuf-devel
yum install rsync -y
2.组件编译
2.1 下载源码
[root@3d852ecb608f /]# cd /usr/local/
[root@3d852ecb608f local]# ls
bin etc games include lib lib64 libexec sbin share src
[root@3d852ecb608f local]# git clone https://github.com/OpenAtomFoundation/pika.git && cd pika

[root@3d852ecb608f pika]#
2.2 切换版本
[root@3d852ecb608f pika]# git checkout v3.3.6
Note: switching to 'v3.3.6'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false
HEAD is now at 9e74c8c vsersion 3.3.6

3.启动
[root@3d852ecb608f pika]# ./output/bin/pika -c ./conf/pika.conf
4.问题解决
4.1问题一：
问题1：使用PORTABLE=1 make编译报如下错：
make[1]: Entering directory `/jrt/pika/third/slash/slash'
g++: error: unrecognized command line option '-msse'
g++: error: unrecognized command line option '-msse4.2'

g++: error: unrecognized command line option '-msse'
问题解决
-msse -msse4.2是x86专属的识别硬件参数，arm没有,利用grep -r msse找到所有带这个参数的文本，进入文本删除该两个参数，若语法中引号中只有该参数，删除该参数时并删除引号

问题解决
#在inlineskiplist.h中约282行，StashHeight函数中增加(void*)，具体见下文
vim /usr/local/pika/third/rocksdb/memtable/inlineskiplist.h
void StashHeight(const int height) {
assert(sizeof(int) <= sizeof(next_[0]));
memcpy((void*)&next_[0], (void*)&height, sizeof(int));
}

4.3问题3：
问题3：执行./output/bin/pika -c ./conf/pika.conf启动服务时只是回显版本，服务未正常启动
问题解决：
yum install rsync -y
#进入pika代码主目录
src/pika.cc 约138行 char c 改为 signed char c
PORTABLE=1 make
./output/bin/pika -c ./conf/pika.conf
#查端口
yum install net-tools
netstat -nltp
- [x] 问题1 等待cmake集成之后，修改slash解决兼容性问题
- [x] 问题2 等待集成cmake之后，升级rocskdb （需要修改blackwidow适配新的rocksdb）
- [x] 问题3已经解决，使用master分支
