与郭德华的gcc-arm-none-eabi交叉编译。

I'm trying to test a cross compile using Terry Guo's gcc-arm-none-eabi. In a nutshell, here are the steps to install on Ubuntu:

我正在尝试使用郭台铭的gcc-arm-none-eabi来测试交叉编译。简单地说，下面是在Ubuntu上安装的步骤:

sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo add-apt-repository ppa:terry.guo / gcc-arm-embedded
sudo apt-get update
sudo apt-get更新
sudo apt-get install gcc-arm-none-eabi
sudo apt-get安装gcc-arm-none-eabi

The problem I am having is I can't find the documentation (or I'm doing something wrong). I know I can't ask for documentation or other off-site resources, so I'll cut right to the chase:

我遇到的问题是我找不到文档(或者我做错了什么)。我知道我不能要求文件或其他非现场资源，所以我直接切入正题:

What is the name of the compiler?
编译器的名称是什么?
Where is the compiler located?
编译器位于何处?
Where are the arm-eabi headers located?
arm-eabi标头在哪里?
Where are the arm-eabi libs located?
arm-eabi libs在哪里?
Where is the arm-eabi sysroot located?
艾比雪藏在哪里?

$ find /usr -iname *arm-eabi*
$ find /usr -iname *gcc-arm*
/usr/share/lintian/overrides/gcc-arm-none-eabi
/usr/share/doc/gcc-arm-none-eabi
$ info gcc-arm-none-eabi
No menu item `gcc-arm-none-eabi' in node `(dir)Top'.
$ man gcc-arm-none-eabi
No manual entry for gcc-arm-none-eabi

The problem was I got Debian's anemic arm embedded tools on Ubuntu 14; and not Terry Guo's tools even though I added Guo's PPA. This can be fixed with:

问题是我在Ubuntu 14上安装了Debian的贫血工具;而不是郭台铭的工具，即使我加入了郭台铭的PPA。这可以用以下方法来解决:

sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi
sudo ap -get remove binutils- armno -eabi gcc- armno -eabi
sudo apt-get autoremove
sudo apt-get autoremove
sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded
sudo add-apt-repository ppa:terry.guo / gcc-arm-embedded
sudo apt-get update
sudo apt-get更新
sudo apt-get install gcc-arm-none-eabi=4-8-2014q2-0trusty10
sudo apt-get安装gcc-arm-none-eabi = 4 - 8 - 2014 - q2 - 0 - trusty10

With the proper package in place:

适当的包装:

What is the name of the compiler?
Where is the compiler located?

编译器的名称是什么?编译器位于何处?

/usr/bin/arm-none-eabi-gcc and friends.

/usr/bin/arm-none-eabi-gcc和朋友。

Where are the arm-eabi headers located?
Where are the arm-eabi libs located?
Where is the arm-eabi sysroot located?

arm-eabi头在哪里?arm-eabi libs在哪里?艾比雪藏在哪里?

SYSROOT is /usr/lib/gcc/arm-none-eabi/4.8.2/armv7-m.

SYSROOT /usr/lib/gcc/arm-none-eabi / 4.8.2 / armv7-m。

I also needed to compile with -mcpu=cortex-m3, -mthumb and --specs=nosys.specs.

我还需要使用-mcpu=cortex-m3， -mthumb和-spec =nosys.specs进行编译。
