We will need to setup target specific flags for the compiler and linkers. You can choose the appropriate BUILD32 and BUILD64 from the table at the bottom of the page.
export BUILD32="[BUILD32 entries]" export BUILD64="[BUILD64 entries]" export GCCTARGET="[GCCTARGET entries]"
Let's add the build flags to ~/.bashrc
to prevent issues if we stop and come back later:
cat >> ~/.bashrc << EOF
export BUILD32="${BUILD32}"
export BUILD64="${BUILD64}"
export GCCTARGET="${GCCTARGET}"
EOF
The following table gives the entires for different Sparc 64 capable processors. Pick the processor that matches your system. Note: GCC settings are only needed in the early sections of the book, and will not be used in the final-system builds.
Table 5.1. List of 32-Bit settings, 64-Bit Build settings, and GCC setting
| Processor | BUILD32 | BUILD64 | GCCTARGET |
|---|---|---|---|
| Ultrasparc and Ultrasparc2 | -m32 -mcpu=ultrasparc -mtune=ultrasparc | -m64 -mcpu=ultrasparc -mtune=ultrasparc | -mcpu=ultrasparc -mtune=ultrasparc |
| Ultrasparc3 | -m32 -mcpu=ultrasparc3 -mtune=ultrasparc3 | -m64 -mcpu=ultrasparc3 -mtune=ultrasparc3 | -mcpu=ultrasparc3 -mtune=ultrasparc3 |
