鲲鹏916安装Ne10出现的问题

先说一下，这个帖子我都在线编辑完了，然后提交的时候网页崩溃了。

然后又在LiberOffice重新写了一遍。

==============================================

错误现象是：

ERROR: Couldn't read the file "/proc/cpuinfo". NE10_init() failed.

Failed to initialise Ne10.

代码是

#include <stdio.h> 
#include <stdlib.h> 
#include "NE10.h" 
int main() 
{  
if (ne10_init() != NE10_OK) 
 {  
 fprintf(stderr, "Failed to initialise Ne10.\n"); 
  return -1;  
 } 
}

返回值是  NE10_ERR 即  -1

我试了其他 NE10_XXXX的函数，都不可运行。

使用的IDE是QT

Qt Creator 4.9.2

Based on Qt 5.12.4 (GCC 9.1.0, 64 bit)

================================怀疑之前安装NE10有错误========

服务器泰山2280 V1 ，鲲鹏916

系统是CentOS7.6

编译器gcc9.1.0

系统自带cmake version 2.8.12.2

安装的是Ne10-v1.2.1-72-g1f059a7

按照Building.md流程安装

在线可在这看：https://github.com/projectNe10/Ne10/blob/master/doc/building.md

=====第一次======

按照这个方式安装

## Native compilation on \*nix platforms

export NE10_LINUX_TARGET_ARCH=aarch64

cmake -DGNULINUX_PLATFORM=ON ..    

-- The C compiler identification is GNU 9.1.0

-- The CXX compiler identification is GNU 9.1.0

======第二次=======================

按照这个方式安装

## Cross compilation on \*nix platforms...

### ...for other general \*nix platforms

export NE10_LINUX_TARGET_ARCH=aarch64

cmake -DCMAKE_TOOLCHAIN_FILE=../GNUlinux_config.cmake ..

-- The C compiler identification is GNU 9.1.0

-- Warning: Did not find file Compiler/-ASM

-- Target architecture: aarch64

-- Building type: RELEASE

-- Configuring incomplete, errors occurred!

###############我找了，我的gcc目录下没有 linux-gnu-as类似的东西########

======第三次=======================

继续上一次的方式

首先，把GNUlinux_config.cmake 文件的57行，注释掉。

elseif(NE10_LINUX_TARGET_ARCH STREQUAL "aarch64")

set(CMAKE_C_COMPILER aarch64-unknown-linux-gnu-gcc)

set(CMAKE_CXX_COMPILER aarch64-unknown-linux-gnu-g++)###（本来没有-unknown-，都是我后加的，为了和编译器一致）

#set(CMAKE_ASM_COMPILER aarch64-unknown-linux-gnu-as)##########注释掉这行####

find_program(CMAKE_AR NAMES "aarch64-unknown-linux-gnu-gcc-ar")

find_program(CMAKE_RANLIB NAMES "aarch64-unknown-linux-gnu-gcc-ranlib")

endif()

执行

export NE10_LINUX_TARGET_ARCH=aarch64

cmake -DCMAKE_TOOLCHAIN_FILE=../GNUlinux_config.cmake ..

-- The CXX compiler identification is GNU 9.1.0

========自以为安装成功了=====

结果出现了帖子开始的情况。。。。

1、我自认为可能是gcc安装有问题。为什么没有ASM的编译器？

2、鲲鹏916支持neon吗，支持硬件浮点运算吗？

3、有可能是Ne10安装有问题，不知道选择那种安装方式：本地编译？交叉编译？

谢谢各位专家，请不吝赐教！
