8.8. Build Flags

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 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 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
