Hi, I needed the GNU toolchain with VFP support because the supplied toolchain does not have floating point support compiled into it. I started with the remarks and the script in thread http://tdg.logicpd.com/viewtopic.php?t=1271. I refined and corrected the script a little. I thought I donate it back to the group. Below you will find a shell script that builds the complete toolchain from scratch. Just put the script in an empty directory on its own an run it. It will start downloading the various tar files, unpack them and build and install the GNU tools. Everything will be build and installed in the directory where the script is located. The first few lines of the script contain some tunable variables. I changed the used versions of the GNU packages from what is mentioned in the 1271 post to the latest (at this moment). When new versions are published you can easily adapt the numbers and run the script again. To get the version mentioned in post 1271 you can replace the versions in the script by this: BINUTILS_VER=2.17 GCC_VER=4.2.1 GDB_VER=6.6 NEWLIB_VER=1.15.0 INSIGHT_VER=6.7.1 # warning: will not compile correctly with the above versions FYI: I only tested it on Ubuntu Gutsy. On my machine the whole process takes about 20 minutes. The directory will take about 1.6 G of disk space at the end. When done, check the log/.err files for errors (they contain lots of warnings for me, I guess that does not hurt. Have fun.
