How To Build NewLib Newlib is a C library intended for use on embedded systems or real time environment system development. It is a mixture of various libraries all under free software license that make them easy to use on embedded systems. For more details visit original site :- https://sourceware.org/newlib/ Why we need Newlib?? We need to port codes from third party sources like freeBSD or NetBSD. Once the code is reviewed and patch is accepted in Newlib then we have to apply the patch in RSB(RTEMS source builder). Newlib Setup steps:- Step 1:- Clone the git repository of newlib in your development folder $ cd development $ git clone git://sourceware.org/git/newlib-cygwin.git Step 2:- Navigate to newlib-cygwin folder and provide the path. $ cd newlib-cygwin $ export PATH=/home/salil/development/rtems/5/bin:$PATH Step 3:- $ cd .. $ mkdir b-sparc-rtems5-newlib $ cd b-sparc-rtems5-newlib $ ../newlib-cygwin/b-sparc
RTEMS Environment Setup First of all you have to see RTEMS open Projects. Then you have to build RTEMS tools and kernels for your project. The tools which I am building is used to create executables which can run on your desired target machine. Prequisites:- First you have to make sure that you are having python 2.7 development version on your PC. Otherwise it will show errors. Step 1 :- $ sudo apt-get install build essentials Step 2:- $ sudo apt-get build-dep binutils gcc g++ gdp unzip git python 2.7-dev Step 3:- $ sudo apt-get install git To get and use all RTEMS Commands we have to set up a Path. In this Path all the GCC executables will be stored. The tools are installed into a build prefix which will be the root of the tree and all the other files are below it which will be used to create a RTEMS applications. Building an RTEMS build will build all autoconf, automake, assemblers, linkers, compilers, debuggers and all the standard RTEMS libr
