| 3 # This script builds and installs binutils, gcc and newlib in the order | |
| 4 # necessary for the whole thing to work. The present version is based | |
| 5 # on OsmocomBB's gnu-arm-build.2.sh script, which is in turn based on | |
| 6 # yet another source. The present version has been concocted by | |
| 7 # Spacefalcon the Outlaw for use in the FreeCalypso project. | |
| 8 # | |
| 9 # This script needs to be invoked with two arguments: | |
| 10 # | |
| 11 # $1: the path to the directory containing the upstream binutils, gcc | |
| 12 # and newlib source tarballs; | |
| 13 # | |
| 14 # $2: the path to the directory where the built toolchain should be | |
| 15 # installed. | |
| 16 # | |
| 17 # Note that there isn't a single install step at the end, instead this | |
| 18 # script will build and install one component, then proceed to build the | |
| 19 # next component which depends on the previous one, etc. For this reason | |
| 20 # you should create a dedicated install directory that is writable by your | |
| 21 # regular (non-root) uid, then run this script to populate that directory | |
| 22 # with the toolchain. | |
