Build Profile

The build profile used by the configure command is an argument of the mkmerge command. There is one default profile for each board, as shown in"Families, Targets and Profiles" . For non-standard system generation, customize the build profile using the information on the file entries described here.

The build profile contains entries of the following type:

• var = value

The range of value values depends on the variable. Note that:

• on and yes are equivalent values (both mean included)

• off and no are equivalent values (both mean not included)

Build profile files provide configuration flags used during the merge. The following listing shows an example microkernel build profile file for UltraSPARC^TM family targets.

The predefined flags include:

Table 4-6 Configuration Flags

Name	Possible values	Description
debug	(off|on)	Indicates whether to compile with debugging information; default is off
devsys	(gcc)	Indicates which host development tool chain is used for compilation; default is gcc
flm	(off|on)	Indicates whether flat memory is in use.
prm	(off|on)	Indicates whether protected memory is in use
vm	(off|on)	Indicates whether virtual memory is in use
locks	(gp|rt)	Specifies which type of locking to use in the core executive; default is gp
merge_dir	(dir)	Specifies the path to the root of the merge tree
optim	(off|on|size|speed)	Indicates how to optimize compilation; setting this flag to speed might make symbolic debugging impossible; default is on, a compromise between size and speed optimizations
profile	(off|on)	Indicates whether to compile with performance profiling capabilities; default is off
shared_lib	(off|on)	Shared library support. Default is on.
softload	(off|on)	Library fp emulation. Default is on.
tree	(dir1,dir2,...)	Specifies projected tree directories to merge
