Development Environment: Ubuntu 10.04, linux-2.6.26.5

Development steps:

1. Install and download software packages that may be used.

Sudo apt-get install bison flex build-essential patch libncurese5-dev

// Libncurese5-dev in 10.04 seems apt-get cannot be found, but the new force can see

You can also report the deb of these software, and then sudo dpkg-I *. deb

2. downgrade the gcc version.

Ubuntu's default gcc is 4.4, and version height is also a problem (this is really speechless, really terrible) but does not need to uninstall 4.4, because the gcc we input in the terminal is just a soft connection to the gcc-4.4, point this soft connection to 4.1. Two methods:

(A). Install apt-get directly.

Sudo apt-get install gcc-4.1

Gcc is overwritten after installation, pointing to the gcc-4.1.

(B) download the software package

Gcc-4.1_4.1.2-23Ubuntu3_i386.deb

Gcc-4.1-base_4.1.2-23Ubuntu3_i386.deb

Cpp-4.1_4.1.2-23Ubuntu3_i386.deb

Then install sudo dpkg-I *. deb

Modify the soft connection after installation

Sudo rm/usr/bin/gcc

Sudo ln-s/usr/bin/gcc-4.1/usr/bin/gcc

3. Modify the sh version

Run: ls-la/bin/sh

The link to/bin/sh is dash. Run the following command:

Sudo dpkg-reconfigure dash

Select no to delete dash

You can run ls-la/bin/sh again to see that it now points to bash. Don't think it's dash ~

4. Create the installation folders crosstool and downloads, preferably in/home/lnux. Do not move them once they are created.

Mkdir/home/linux/downloads, and input crosstoll-0.43.tar.gz. In addition, there are other source code packages to be used below. If not, the packages will be automatically downloaded below.

5. Unzip the crosstool-0.43.

Cd/home/linux/downloads

Tar-zxvf crosstool-0.43.tar.gz

Cd crosstool-0.43

There are many scripts and configuration files in this directory, and each supported processor has corresponding scripts. The demo-arm-softfloat.sh we choose now is to build an arm cross-compilation toolchain that supports soft floating points
