### 1.问题描述

使用PORTABLE=1 make编译报如下错：

```bash
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'
g++: error: unrecognized command line option '-msse4.2'
g++: error: unrecognized command line option '-msse'
g++: error: unrecognized command line option '-msse4.2'
g++: error: unrecognized command line option '-msse'
g++: error: unrecognized command line option '-msse4.2'
g++: error: unrecognized command line option '-msse'
g++: error: unrecognized command line option '-msse4.2'
g++: error: unrecognized command line option '-msse'
```

### 2.问题分析

```bash
-msse -msse4.2是x86专属的识别硬件参数，arm没有,需要删除
```

### 3.问题解决

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

```bash 
[root@598939ec6129 pika]# grep -r msse
Makefile:PLATFORM_CXXFLAGS= -std=c++11 -fno-builtin-memcmp -msse -msse4.2 
third/blackwidow/benchmark/Makefile:CXXFLAGS=-O2 -std=c++11 -fno-builtin-memcmp -msse -msse4.2
third/blackwidow/tests/Makefile:CXXFLAGS= -g -std=c++11 -fno-builtin-memcmp -msse -msse4.2
third/blackwidow/Makefile:CXXFLAGS= -g -std=c++11 -fno-builtin-memcmp -msse -msse4.2 -pipe -fPIC
third/blackwidow/examples/Makefile:CXXFLAGS=-O2 -std=c++11 -fno-builtin-memcmp -mss -msse4.2
```
