Ubuntu 常见问题

yexiang@ubuntu:~/uboot$ arm-linux-g++ -v

/opt/FriendlyARM/toolschain/4.4.3/bin/arm-linux-g++: 15: exec: /opt/FriendlyARM/toolschain/4.4.3/bin/.arm-none-linux-gnueabi-g++: not found

• 这个问题是 ubuntu 64位 需要安装一些32位的库文件
• sudo apt-get install ia32-libs 或者 提示

However the following packages replace it:
  lib32ncurses5 lib32z1

In file included from tools/aisimage.c:10:0: 
include/image.h:920:27: fatal error: openssl/evp.h: 没有那个文件或目录 
# include <openssl/evp.h> 
^ 
compilation terminated. 
scripts/Makefile.host:111: recipe for target 'tools/aisimage.o' failed 
make[1]: *** [tools/aisimage.o] Error 1 
Makefile:1194: recipe for target 'tools' failed 
make: *** [tools] Error 2 

• 这个是 openssl 的依赖的问题，运行命令sudo apt-get install libssl-dev 即可解决

./scripts/dtc-version.sh: 行 17: dtc: 未找到命令 
./scripts/dtc-version.sh: 行 18: dtc: 未找到命令 
*** Your dtc is too old, please upgrade to dtc 1.4 or newer 
Makefile:1353: recipe for target 'checkdtc' failed 
make: *** [checkdtc] Error 1

• 好吧，dtc 是 device-tree-compiler的缩写，即设备树编译器，说明系统中没有安装这个编译器 安装不就行了

sudo apt-get install device-tree-compiler 
sudo apt-get install build-essential
// 编译程序必须的软件包
// Ubuntu缺省情况下，并没有提供C/C＋＋的编译环境，因此还需要手动安装
// 如果单独安装gcc以及g 比较麻烦，幸运的是，为了能够编译Ubuntu的内核，Ubuntu提供了一个build-essential软件包

# 查看该软件包的依赖关系，可以看到以下内容
apt-cache depends build-essential
build-essential
 |Depends: libc6-dev
  Depends: <libc-dev>
    libc6-dev
  Depends: gcc
  Depends: g++
  Depends: make
    make-guile
  Depends: dpkg-dev

In file included from scripts/kconfig/lxdialog/checklist.c:24:

compilation terminated.

• 查找资料后得知，最小系统不支持图形显示造成 解决方法：

sudo apt-get install libncurses5-dev
// libncurses5-dev是Ubuntu操作系统内核编译工具

/bin/sh: 1: bc: not found

• 解决方法：sudo apt-get install bc

fatal error: sys/cdefs.h: No such file or directory

• 解决方法：

sudo apt-get purge libc6-dev
sudo apt-get install libc6-dev
sudo apt-get install libc6-dev-i386
sudo apt-get install lib32readline*
