We will need to setup target specific flags for the compiler and linkers.
export BUILD64="[BUILD64 entries]"
To prevent errors when you come back to your build, we will export these variables to prevent any build issues in the future:
echo export BUILD64=\""${BUILD64}\"" >> ~/.bash_profile
The following table gives the entries 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 8.1. 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 |
