OpenRISC Development GNU Tool Chain Repository |
============================================== |
|
This directory is where you will find all the source trees for the development |
version of the GNU tool chain. The newlib library is included, since that is |
required for GCC testing. The code in this directory should be functional, but |
is not considered stable. |
|
Note that the Linux tool chain requires uClibc and Linux, which should be |
downloaded using git. |
|
Stable release source trees are found in the gdb-src directory. |
|
The file structure mirrors that of the main Free Software Foundation |
repository. There are two main directories: |
|
"or1k-src" mirrors the upstream src directory and contains the code for |
CGEN, binutils, newlib, gdb and associated libraries. |
|
"or1k-gcc" mirrors the upstream gcc directory and contains the code for gcc |
and its associated libraries. |
|
The tool chains (or1k-elf for bare metal and or1k-linux-uclibc for Linux |
applications) are built using a source tree, combining these two |
directories. |
|
Three scripts are provided |
|
"bld-elf.sh" to build the newlib tool chain |
"bld-linux-uclibc.sh" to build the uClibc tool chain |
"bld-all.sh" to build both tool chains |
|
By default the tests (which require DejaGnu to be installed) are *not* run. |
|
Any questions should be posted on the OpenRISC forum at |
opencores.org/forum,OpenRISC, or discussed on IRC at freenode.net, channel |
#opencores. |
