5.4. Build Flags

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:

echo export BUILD32=\""${BUILD32}\"" >> ~/.bashrc
echo export BUILD64=\""${BUILD64}\"" >> ~/.bashrc
echo export GCCTARGET=\""${GCCTARGET}\"" >> ~/.bashrc

The following table gives the entires for different Sparc 64 capable processors. Pick the processor that matches your system.
