We will need to setup target specific flags for the compiler and linkers.
export BUILD64="[BUILD64 entries]" export GCCTARGET="[GCCTARGET entries]"
Lets add the build flags to ~/.bashrc
to prevent issues if we stop and come back later.
cat >> ~/.bashrc << EOF
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 architectures, target triplets, and recommended book
| Processor | BUILD64 | GCCTARGET |
|---|---|---|
| Ultrasparc and Ultrasparc2 | -m64 -mcpu=ultrasparc -mtune=ultrasparc | -mcpu=ultrasparc -mtune=ultrasparc |
| Ultrasparc3 | -m64 -mcpu=ultrasparc3 -mtune=ultrasparc3 | -mcpu=ultrasparc3 -mtune=ultrasparc3 |
