Ubuntu 16.04 installation ARM-LINUX-GCC embedded cross-compilation environment issues summary

Cackle:

Internship for nearly half a year has been doing hardware and the bottom of the drive, recently found a job to find a high demand for Linux, but also a lot of jobs, so the recent time in the occasional contact with Linux.

Text: ( I started to write a blog, not enough preparation, pictures are not saved )

The first is to surf the internet to find out the ready-made tutorials, the following URL is a good tutorial

Http://www.cnblogs.com/softhal/p/5699381.html

Tertiary, I did it all.

　　But at the fourth step, there were some problems for me as a novice:　　

1, the first method, modify the BASHRC file, will always appear the following this hint

* * (gedit:5488): WARNING *: Set document metadata failed: Setting properties not supported Metadata::gedit-position

I have started also very puzzled, always thought out of what mistake, the internet looked up a bit to say this neglect, OK then I also ignored, also did not go to delve into.

And after I changed the file,

I have started also very puzzled, always thought out of what mistake, the internet looked up a bit to say this neglect, OK then I also ignored, also did not go to delve into.

2, and I changed the file after the use of the SOURCE/ROOT/.BASHRC command to display insufficient permissions so I tried the next method.

3,sudo gedit/etc/profile This command to open the profile file on my Computer fonts are gray, no keyword font color changes, I also gave up this method.

Direct third method, simple violence, after the change, restart, enter $echo PATH in the shell to see if the environment configuration is successful.

　　

Here I thought everything was all right, and arm-linux-tab have a normal reaction, but the input arm-linux-gcc-v, found that something was not found, so I went to the relevant folder checked a bit, Found 4.4.3 folder locked, so I feel this is the pot of lock, so I looked for the Internet to remove the folder lock instructions:

　　sudo chmod-r 777 files or folders (first to reach the 4.4.3 directory)

Then the version number will appear when you enter Arm-linux-gcc-v, which means the installation is successful.

Then I quickly set up a hello.c file to try to cross-compile the environment, but found that the following error occurred:

While loading shared Libraries:libstdc++.so.6:cannot open Shared object file

　　Workaround: sudo apt-get install lib32stdc++6

　The pro-test can be used.

Final input Arm-linux-gcc-o Hello hello.c

No error, this is the official installation success.

Also came here, Hangzhou winter frozen feet, want to go back to the Northeast!
