In this issue, the editor will bring you about what the Ubuntu embedded cross-compilation environment arm-linux-gcc is like. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

1. Download the installation package

Download arm-linux-gcc-4.4.3.tar.gz and store it in a directory

2. Extract the installation package

Extract the installation package in the stored directory

Tar-zxvf arm-linux-gcc-4.4.3.tar.gz-C / usr/local/arm-linux-gcc-4.4.33, add environment variable sudo vi / etc/profile

Add on the last line

Export PATH=$PATH:/usr/local/arm-linux-gcc-4.4.3/bin

Write and save.

4. The environment variable takes effect source / etc/profile5, and test arm-linux-gcc-v

The following error prompt appears

/ usr/local/arm-linux-gcc-4.4.3/bin/arm-linux-gcc: 15: exec: / usr/local/arm-linux-gcc-4.4.3/bin/.arm-none-linux-gnueabi-gcc: not found

It is said that the reason for this problem is that Ubuntu uses 64-bit, and the solution is to use commands.

Sudo apt-get install lib32z1 lib32ncurses5

Install some 32-bit libraries

After installing the 32-bit library, use the command

Arm-linux-gcc-v

It was a success this time.

6. Verification

Compile a hello.c file

# include int main () {printf ("hello worldviews!\ n"); return 0;}

Use the command

Arm-linux-gcc hello.c-o hello

The following error prompt appears

/ usr/local/arm-linux-gcc-4.4.3/bin/../libexec/gcc/arm-none-linux-gnueabi/4.4.3/cc1: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directorysudo apt-get install lib32stdc++6

After installation is complete

Arm-linux-gcc hello.c-o hello
