Create an arm cross compiler Arm-Linux-GCC on ubuntu0.94 using crosstool 0.43

I. Ensure that the following software packages are installed on Ubuntu

 

Bison
Flex
Build-essential
Patch
Libncurses5-dev

 

View the dependency of the software package. You can see the following:

$ Apt-Cache depends build-essential

 

Install the package using $ sudo apt-Get install package name

 

II. Crosstool

Crosstool is a set of script tools that build and test different versions of GCC and glibc for those architectures that support glibc. It is also an open-source project, namely http: // kegel.com/crosstool. It is much easier to build a cross-tool chain using crosstool than to compile the tool chain by step. This method is recommended for readers who only need to build a cross-compilation tool chain for their work. Use the crosstool tool to build the required resources, as shown in.

Table 2.2 required resources

3. Crosstoo Installation Steps

 

1. Prepare resource files

First, download the required resource files from the Internet, put these toolkit files under the newly created $ home/downloads directory, and then decompress crosstool-0.43.tar.gz in the $ home/downloadsdirectory. The command is as follows:

# Cd/home/zhoug/downloads (note $ home =/home/zhoug)

# Tar-xzvf crosstool-0.42.tar.gz

(

For the tar.bz2 file, decompress the command

# Tar-xjvf xxx.tar.bz2

)

2. Create a script file

# Cd home/downloads/crosstool0.43

# Cp demo-arm9tdmi.sh arm. Sh

# Sudo gedit arm. Sh

 

#! /Bin/sh
# This script has one line for each known working toolchain
# For this architecture. uncomment the one you want.
# Generated by generate-demo.pl from buildlogs/all.dats.txt

Set-ex
Tarballs_dir = $ home/downloads # resource download directory
Result_top =/opt/crosstool # The final directory generated by the compilation tool
Export tarballs_dir result_top
Gcc_languages = "C, C ++" # definitions support C and C ++ languages
Export gcc_ages

# Really, you shoshould do the mkdir before running this,
# And chown/opt/crosstool to yourself so you don't need to run as root.
Mkdir-p $ result_top

# Eval 'cat arm9tdmi. dat gcc-3.2.3-glibc-2.2.5.dat 'sh all. Sh -- notest
# Eval 'cat arm9tdmi. dat gcc-3.2.3-glibc-2.3.2.dat 'sh all. Sh -- notest

# Eval 'cat arm9tdmi. dat gcc-3.3.6-glibc-2.3.2.dat 'sh all. Sh -- notest
# Eval 'cat arm9tdmi. dat gcc-3.3.6-glibc-2.3.2-tls.dat 'sh all. Sh -- notest
# Eval 'cat arm9tdmi. dat gcc-3.4.5-glibc-2.2.5.dat 'sh all. Sh -- notest

# Eval 'cat arm9tdmi. dat gcc-4.0.2-glibc-2.3.5.dat 'sh all. Sh -- notest

Eval 'cat arm9tdmi. dat gcc-4.1.0-glibc-2.3.2-tls.dat 'sh all. Sh -- notest -- nounpack

Echo done

 

3. Create a configuration file

# Gedit arm9tdmi. dat

Bytes ----------------------------------------------------------------------------------------------------------

Kernelconfig = 'pwd'/arm. config
Target = arm-Linux # compiled tool chain name
Gcc_extra_config = "-- with-CPU = arm9tdmi -- enable-cxx-flags =-mcpu = arm9tdmi"
Target_cflags = "-o"

 

Bytes ----------------------------------------------------------------------------------------------------------

# Gedit gcc-4.1.0-glibc-2.3.2-tls.dat

Binutils_dir = binutils-2.16.1
Gcc_core_dir = gcc-3.3.6
Gcc_dir = gcc-4.1.0
Glibc_dir = glibc-2.3.2
Linux_dir = linux-2.6.15.4
Linux_sanitized_header_dir = linux-libc-headers-2.6.12.0
Glibcthreads_filename = glibc-linuxthreads-2.3.2
Gdb_dir = gdb-6.5
Glibc_extra_config = "$ glibc_extra_config -- With-TLS -- With-_ thread -- enable-kernel = 2.4.18"

Bytes ----------------------------------------------------------------------------------------------------------

4. Execute the script

After preparing the crosstool script file and configuration file, run the arm. Sh script to compile the cross-compilation tool. Run the following command:

# Cd crosstool-0.43

#./Arm. Sh

 

5. Set Environment Variables

# Sudo gedit/etc/bash. bashrc

Export Path = $ path:/opt/crosstool/gcc-4.1.0-glibc-2.3.2/ARM-Linux/bin:

 

4. Compilation errors

 

1. The GCC version on my machine is GCC 4.3.3, and an error occurs during compilation.

GCC version high or low, sudo apt-Get remove GCC, sudo apt-Get install gcc-4.1. Because ubuntu can install multiple versions of GCC, I only execute

Sudo apt-Get install gcc-4.1.

After installing gcc-4.1

Sudo RM/usr/bin/GCC (delete GCC, it's just a soft connection file to the gcc-4.3.2)
Sudo ln-S/usr/bin/gcc-4.1/usr/bin/GCC (build a soft connection from GCC to gcc-4.1)

 

2. The error is as follows:

Make [2]: *** [/home/zhoug/downloads/crosstool-0.43/build/ARM-Linux/gcc-4.1.0-glibc-2.3.2/build-glibc/CSU/version. O] Error 1
Bash: Make [2]: The command cannot be found.
Make [2]: Leaving directory '/home/zhoug/downloads/crosstool-0.43/build/ARM-Linux/gcc-4.1.0-glibc-2.3.2/CSU'
Make [1]: *** [CSU/subdir_lib] Error 2
Make [1]: Leaving directory '/home/zhoug/downloads/crosstool-0.43/build/ARM-Linux/gcc-4.1.0-glibc

 

Solution:

Modify the following file:
Gedit/crosstool0.43/build/ARM/Linux/gcc-4.1.0-glibc-2.3.2/build-glibc/CSU/version-info.h
"Available extensions:/N"
"/N"
Vim Demo-arm.sh.
Add -- notest -- nounpack after the tool chain version

 

3. Other online errors

1) "Install GCC" after installing the gcc-4.1, re-compile. Have you thought about this ?! No, the following error occurs:
In file already ded from version. C: 33:
/Home/tekkaman/working/crosstool-0.43/build/arm-9tdmi-linux-gnu/build-glibc/CSU/gcc-4.1.1-glibc-2.3.2: 2: 1: Missing terminating "Character
/Home/tekkaman/working/crosstool-0.43/build/arm-9tdmi-linux-gnu/build-glibc/CSU/gcc-4.1.1-glibc-2.3.2: 3: 1: Missing terminating "Character
Google found that Ubuntu set the system's default shell to dash (the Debian almqualified shell), so the file format generated by the script is different from that generated by bash, resulting in compilation errors. In use

Sudo ln-SF bash/bin/sh

 

2) An error was reported when Skyeye was compiled today.
/Usr/include/bits/fcntl2.h: 51: Error: Call '_ open_missing_mode'. The declared error attribute: open with o_creat in second argument needs 3 arguments
It can be compiled in ora 10. It should be okay in Ubuntu, but this problem occurs. Quickly follow up. First, compare the two versions of/usr/include/bits/fcntl2.h, and find that there is no difference, that is, the code problem. Code change. The error message is in line 1.
If (! NF-> writebuffer)
Free (NF-> writebuffer );
Free (NF );
The error message is "Open", but the first row is "free". If you comment out the first two rows, the false positive is "free (NF)". Continue to comment out "free (NF)". Finally, the error is given, if (NF-> fdump = open (Dev-> dump, file_flag) 0 in the row 519)
Open has only two parameters. Add a 0777 parameter and the code is (if (NF-> fdump = open (Dev-> dump, file_flag, 0777) 0)
Thank God. The compilation is successful.

Arm-Linux-ar Stack Overflow

It is mainly about the 4.3.2 compiler. Change it to the 4.1 compiler.
