Using crosstool-0.43 to generate cross-compiler for ARM

Using crosstool-0.43 to generate cross-compiler for ARM 

 

[Environment setting] 

Ubuntu-10.04 

 

apt-get install patch 

apt-get install bison 

apt-get install flex 

 

apt-get install uboot-mkimage 

apt-get install libncurses5-dev 

 

 

[Initial prepare] 

1: download crosstool-0.43.tar.gz from 

http://kegel.com/crosstool 

2: unzip tar 

 

[Configuration] 

1: demo-arm.sh 

this script is the overall control, uncomment the line that you want to build for specific gcc and glibc version 

e.g.: uncomment the line 

eval `cat arm.dat gcc-3.4.5-glibc-2.3.2.dat` sh all.sh --notest 

 

2: set dirs: 

TARBALLS_DIR: set download tarballs 

RESULT_TOP: set the final build dir 

 

[Running] 

$sh dem0-arm.sh will start the build 

 

[Notes for some internal procedure] 

1: the tool will check and download necessary packages in folder TARBALLS_DIR 

2: the internal files are in folder crosstool-0.43/builds 

3: one drawback is that the scripts will process a tarball one at a time, e.g.: it will do download-unzip-patch-compile procedure for each tarball. If anyone is missing or compile error, run the script again will redo the whole thing 

4: Some error needs to be resolved. see page Resolving some errors 

 

 

Resolving some errors 

 1: Need to lower down gcc version
